Joker (character)

Jack Jones (also known as Kaitou Joker, or Phantom Thief Joker) is the main character of Kaitou Joker and one of the first apprentices of Kaitou Silver Heart.

Appearance
Joker has bluish white hair and blue eyes, along side an unusual blue scar on his left eye.

Joker usually wears a dark blue hat, with a blue and white check theme along it, purple googles, a red suit with a blue shirt and yellow tie, with a yellow J on the chest, a purple cape, purple shoes and white gloves.

As a child, he wore a blue shirt and red pants with suspenders.

Joker has had a many different disguises so far in the series.

Personality
Joker is childish a lot of the time, but he can also act like an adult at times where it matters. He loves to eat (his favorites being curry or hamburger steak), and likes Hachi's cooking to the point where he describes it as "best in Japan". He has a pretty high sense of loyalty towards his "profession" and refuses to call anyone who doesn't act phantom-thief like a Phantom Thief. While he really is the short-tempered type, he sometimes exaggerates it to lure his enemies to fall into his traps, and doesn't hesitate to throw his ego away and act desperate even though he knows he's already won. Not only does he like to fool his enemies with magic tricks but he's also very clever and uses of psychology whenever it's needed.

Before Series
Formerly known as Jack Jones, he lived with his mother and father in their manor. Life was happiest for him at this time with his family and everything he'd need.

But his parents died shortly in a place accident after he received the code to find the key he wanted so badly from his father. Not believing at first, he stayed in his family's mansion alone believing his parents would return. Night after night he scared thieves away, who wanted to steal his father's treasure.

One night, he received a note from Silver Heart, saying he would come for the treasure and Jack thought that was just another pathetic thief. Silver Heart had to put up with a lot, including cages and ultimately gets hit on the head from Jack by the remote Jack had. He was tied to the safe by Jack and the doorbell rang, revealing Jack's parents. But those two were Professor Clover and his female assistant, dressed up as the Jones'. Jack only found out that they were fake after they returned to the hall with the safe (Silver Heart was gone) and they acted strange, meaning they forgot about several important things (like his father makes the curry, not the mother). Even though they were small differences, that was enough for Jack to see through their disguise. After that, they turned into two figures with silly outfits, introducing themselves.

Professor Clover tried to hurt, or rather kill Jack, who was clever enough to use the remote, activating a few traps and hide. But as he fled through the vent a cat chased after him, this cat was Professor Clover's assistant, who turned from human form into a cat.(This may have contributed to his fear of cats, although it has not been confirmed).

A little later, as the Professor grabbed Jack and lifted him into the air, Silver Heart reappeared. After a silly sentence ("I wanna kick that little boy's ass!" and Jack's "AND YOU CALL YOURSELF A GROWN UP?!") coming from him, they made a deal. Silver Heart found the key in a family picture of the Jones, after which he opened the safe and traded the treasure for Jack. There was a little fight (Clover and his assistant ended up pinned to the magnetic safe and the treasure broke) after what the Professor and his assistant, a woman if I should mention, disappeared.

Jack later gave Silver Heart what was left from the treasure and he flew away on his plane. He looked back, hoping that Jack would be okay all alone in this mansion, but a voice from behind him said "It's Jack!". In the end it turned out that Jack sneaked on the plane and became Silver Heart's student in order to make "miracles" as well.

"Welcome to the shining night!" were Silver Heart's last words after what they flew away, and the flashback in the episode ended. (Episode 5, for those who want to know.)

After his intense training with Silverheart, he entered the Phantom Thief Academy, along with Queen, Spade, and Roko from which they all graduated before becoming professionals (vols 18 & 19).

Episode 01
In the beginning of the episode Joker is stealing the treasure the Golden Elephant (This is presumably Joker's first mission as a Phantom Thief since the crowd seemed confused on who he was, causing him to introduce himself while escaping.) Hachi is standing in the crowd watching Joker's spectacle with awe. Joker then sends an advance notice to Kaneari saying that he will be stealing the Dragon Gem. Joker disguises himself as Kaneari's assistant Kaneko after he put her to sleep with his sleeping powder cookies and while checking out the room with the gem in it, he discovers Hachi who is hanging on the edge of a spike trap that he triggered in an attempt to steal the Dragon Gem. While teasing Hachi, Joker hears the guards running to the room after they discovered the camera was blocked (Hachi covered it up when he came into the room) and quickly hauls Hachi up, while disguising himself as Kaneari. He then tricks the guards to return to their stations and covers up the camera with an image card. It is then that Joker introduces himself to Hachi and then he heads toward the treasure to steal it. Hachi then blocks his path stating that "I have to have this!". Joker grabs him and tries to make him move so he can steal the treasure but Hachi clings to him and reveals that Kaneari stole the Dragon Gem from his village and he came to steal it back. Joker then tells him "Even so, being a burglar isn't good." to which Hachi points out that he is a burglar too since he came to steal from Kaneari as well. Joker then uses Joker Vision to examine the case while telling Hachi the difference between Burglars and Phantom Thieves. While searching the case, Joker discovers that there is a bomb on the case and explains to Hachi that if anyone other Kaneari opens the case it will explode. Hachi refuses to accept that and tries to find another way to open the case. Joker was about to warn Hachi when he noticed the eyes of one of the paintings behind Hachi was glowing. He rushed up there and pushed Hachi out of the way, getting his leg wounded in the process (It also triggered the alarm). Hachi bandages Joker's leg up and starts to escape when Joker tells him that he was still going to steal the treasure. When Kaneari and his men bust in through the door they find the room empty and two pedestals instead of one. Joker then walks in disguised as Oniyama and tells Kaneari that one of the cases is a fake. To figure out which is the real one Kaneari twists his pink bear's(Kintaro) nose and the real case opens. He then points a gold pistol to Oniyama(Joker) and tells him that he knows he is Joker due to his leg injury. Joker then reveals himself and the fake pedestal turns out to be Hachi, who used image gum to disguise himself. Joker then throws his J on the ground and creates a smokescreen. In the smoke he disguised all of the guards and Kaneari as himself and then disguised Hachi and himself as Kaneari to escape (Hachi steals the Dragon Gem during the smokescreen). After escaping the mansion Joker tells Hachi he can have the treasure and Hachi (who ends up being impressed by Joker's tricks and skill) asks Joker to let him become his apprentice. Joker turned him down at first but when Hachi cleaned up his messy ship and made him his favorite food(curry) he reconsidered and asked Hachi to become his apprentice.

Episode 02
Joker and Hachi head to Paris to steal the Recollection of Napoleon, which is inside the 100-year safe that only opens up every 100 years. Joker shows up at the museum disguised as Inspector Oniyama and meets the detective Viridian. Viridian reveals Joker after calling Oniyama on his cellphone (Oniyama was in a different part of Paris making salty ramen in an effort to find out where Joker was), Joker and Hachi then reveal themselves. Joker tells Viridian that he already stole the painting and takes it out without showing the picture. Viridian tells Joker he is bluffing and they both wait for the safe to open. When the safe opens, it reveals a childish drawing and Joker turns around the painting to show that he indeed, had already stolen it. Joker and Hachi then head for the exit only to discover that Viridian had painted over the door and Virdian tells Joker that the room spins along with the clock on the safe. Joker and Hachi then rush around trying to figure out where the exit it but it was futile due to Viridian painting new pictures as Joker and Hachi tore the others down. In a last ditch effort, Joker pulls out a bomb card (which is a joker card) and attempts to blow a hole in the wall to escape. Before he could throw it however, his cape tickles Hachi's nose and he sneezes, causing Joker to drop the card. Hachi runs up to grab it but is stopped when Viridian throws a paintbrush at him. Joker rushes between Viridian and Hachi to which Viridian seizes the moment and handcuffs him. Viridian then takes the "childish" painting from inside the safe and tosses it back to Joker believing that Joker had painted it. At that moment a delivery guy walks in delivering the food that Hachi ordered and reveals the exit. Joker and Hachi seize their chance and run towards the exit but Viridian prevents them from escaping by attacking them with his paint. Hachi then runs to the closing safe in order to retrieve the painting but gets knocked in the safe and a vase gets stuck on his head after dodging Viridian's attack. Joker runs up to the safe and jams the gears with a piece of image gum (which prevented the safe from fully closing) and at the same time throwing a card that made a smokescreen for their escape. Hachi apologizes to Joker while making him some salty ramen from Oniyama's stand (he abandoned it after hearing the curator's scream) since he thought they didn't manage to get the treasure. Joker the says "What are you talking about? It was a huge success!". It is then revealed that Joker used the list that depicted all of the things in the safe to make Viridian think that Joker's painting was the real one instead. After eating his ramen Joker runs off to steal more treasures with Hachi following close behind.

Episode 03
Joker and Hachi sneak into Kaneari's private luxury cruise ship in order to steal the Mermaid's Crystal. While on board they run into Joker's rival Spade,also known as King and his assistant Dark Eye.(King and Joker were raised under the same master) When they first met Joker assumes that Dark Eye is the Phantom Thief Spade due to the spade mark he wears, and King is his apprentice. King decides to not correct him and they both begin to go for the treasure. King attempts to steal the crystal by using Dark Eye's evil glance(Which works like Joker's Straight Flash) to blind them while King uses a tranquilizer gun to put them to sleep. However it doesn't work because Joker had taken King's tranquilizer gun and replaced it with a fake one made of image gum. Dark Eye is then captured and Joker uses this chance to go for the treasure himself. Joker then walks out on stage as himself but isn't immediately arrested due to the fact that Kaneari dressed up as Joker before and fiercely yelled at the police for tackling him. Oniyama still was suspicious and asked Joker to remove his mask and which Oniyama tore it off for him revealing Kaneari again (but this time it was actually Joker disguised as him). Kaneari(still Joker) suggests that he should win the Mermaid's Crystal since he fooled the police twice and declared himself the winner. Before Joker could leave with it however another Kaneari popped up (this one is King) and stated that the other Kaneari (Joker) is a imposter. This causes them to argue and reveal themselves to the inspector, who locked them up in a special cage (Dark Eye was locked up in it earlier but King helped him out before disguising himself as Kaneari). At this point it is revealed that one summer(in their childhood) King put soy sauce in Joker's drink and to get revenge, a furious Joker(Known as Jack at that time) tied a parachute to King's bed and dropped him out of an airship they were in. While they were arguing, Dark Eye and Hachi worked together in order to free their respective masters. Hachi made curry and Dark Eye applied sleeping powder to it to make everyone at the party fall asleep. After being freed Joker takes the Mermaid Crystal and sends it up to his airship "The Sky Joker" only to find out King disguised his airship as Sky Joker and ended taking the treasure from Joker. *It should also be noted that around this time Joker finds out that King is actually Spade.* Hachi was shocked there was someone that could actually out smart Joker, while Joker vowed to beat him next time.

Episode 04
Joker plans to steal the Ice Sculpture of Odin, which is on display on the 88th floor on the skyscraper known as the Valhalla Tower. While heading to the elevator, Joker recognizes Spade in the crowd heading for the elevator and he attempts to kick him only to be stopped by Dark Eye. Dark Eye holds him down and tells Spade to go ahead and steal the treasure. Before Spade could go however, Hachi intervenes which causes a scuffle in the elevator. In the scuffle, Joker accidentally hits the machine on Hachi's back (It was designed to help them get the treasure out of the room) this causes the machine to malfunction and the balloon on the device expands, sending Joker and Spade out of the elevator while sending Hachi and Dark Eye up to the 88th floor. While Joker and Spade are waiting for the elevator to come back down they notice people running down the stairs yelling there was a fire. Joker and Spade then rush up the stairs to the 88th floor to discover their respective apprentices with other people trapped on the floor along with the treasure. Due to the circumstances, Joker and Spade team up and work together to get everyone out of the building. They use Joker's balloon machine to launch the elevator up to the roof (after Spade fixes it) and then used bomb cards to make a hole for it to pop out of. After successfully escaping, both thieves return to get the treasure (it didn't melt in the fire due to Joker using his machine to make the glass containing the sculpture a vacuum.) and manage to successfully escape the police again but this time with the treasure. Spade and Joker are seen at the end fighting over who deserves the treasure while Silver Heart is watching them from a distance

Episode 05
While Hachi is cleaning Joker's room, he discovers a key and asks Joker (who walks in asking for food) what it was for. The episode then flashbacks to Joker's childhood. Joker's father had a treasure called the Time Goddess and kept it locked in a special case. Joker (known as jack at this time) rather than like the treasure, ended up liking the key that unlocked the safe instead. His father amused by this, set up a riddle for Jack to solve and hid the key for him to find while they were gone on a 3 day business trip. However the plane carrying the Jones' crashed into the Pacific ocean and they were announced to be missing. Jack refused to accept this and kept intruders from stealing the treasure, while also trying to solve his father's code. He continued this until Silver Heart came to the mansion to steal the treasure. After trapping Silver Heart, Jack's parents miraculously returned to the house. Jack was overjoyed at first but then began to realize that they were not his parents after they made a few slight mistakes (Such as when he told Jack his mom will make the curry, when his dad is the one that usually makes it). The fakes reveal themselves and attempt to capture Jack in order for him to tell them where the key is for the safe. Jack was captured eventually but before they could do anything, Silver Heart shows himself after successfully escaping Jack's trap.Silver Heart then solved the riddle and prevented them from stealing the Time Goddess (Although it broke during the chaos). Jack then gave Silver Heart the remains of the statue and Silver Heart flew off in his propeller plane, wondering if Jack will be alright. After he says "Be well,boy", Jack pops up behind him saying "It's Jack!" and asks him if he could become his apprentice. Much like Joker with Hachi, Silver Heart rejected the idea at first but then allowed Joker to become one of his apprentices. The episode ends with Silver Heart calling Joker (present) saying he needs help because he threw out his back again.

Episode 06
Joker is framed for serious of thefts involving "violent measures" around the world. It is then revealed by Spade that there is a person impersonating Joker. Spade tells Joker that imposter plans to steal the Gemini Crown that is located at the Moonlight Grand Hotel, so they form a plan to find out who is doing this while also clearing his name. The episode then goes to Joker(who is actually Spade) and Hachi heading in the hotel disguised as a camera crew. While they are in the room, the treasure is stolen and "Joker" points out the imposter who was disguised as Ginko (one of the officers, the one with purple hair). The imposter introduces himself as Shadow Joker and Oniyama (who is Joker), Hachi, and "Joker" head off after him. After tricking Shadow, Joker reveals himself and so does Spade. Joker asks Shadow why he is pretending to be him and Shadow gives him a vague reply (He says "I see so you don't know. Then that is all the more reason I can't say why.") and then uses the temporary distraction from the police to escape. Joker then uses the video to prove his innocence and him and Spade are seen at the end of the episode fighting over who gets the crown. *It should be noted that Joker has it in a later episode, so it is assumed that Joker eventually won.

Episode 07
Joker and Hachi are after a gem called the Scarlet Heart, which legends say once belonged to the island's great king. After climbing a cliff and finding the village, they discover the villagers being harassed by a group of people with a clover emblem. One of the men discovered a stone tablet that has a riddle that will lead to the treasure after searching the Elder's House. Thinking the Elder was holding information the general, who they call General Manbou, tries to whip the elderly man for his insolence. Before he could do that, Joker used what he calls his "Joker Kick" and kicks him to the ground while taking the tablet from him. After exchanging some dialogue Joker and Hachi escape with gunfire on their backs. After escaping with the tablet, they run into Spade and Dark Eye who are also after the treasure as well. Spade suggests that they team up and they both begin to try to solve the mystery behind the tablet. Spade leads them to a statue that the riddle refers to but before they could solve the rest Manbou appears and drives them to a cliff. It is on that cliff that Joker solves the rest of the riddle and tries to prevent Manbou from taking the tablet as well as seeing where the treasure is. At that moment Spade holds his gun to Joker's head and tells him to give the tablet to Manbou so he wouldn't shoot them. Joker attacks back but Spade still manages to shoot him. Dark Eye then knocks out Hachi and Spade gives the tablet to Manbou. He and his minions head to the statue and apply it to the tablet shaped hole where the statue's finger was pointing. It ended up being a trap and the statues hand comes down and traps Manbou and his men under it's giant golden hand. It is then Joker and Hachi come up and it is explained that Spade shot Joker with a paintball filled with fake blood to make it look like he shot and killed Joker. Joker tells Manbou that "Like our master says:"A Phantom Thief has no need of killing tools.After, Joker tells the others that he figured out the rest of the riddle while on the cliff and explains that they need to head to the point that the statue's shadow pointed to instead of the actual statue's finger. They head to that spot and dig up the container that has the Scarlet Heart inside. As usual Joker and Spade fight over who should get the treasure but the Elder and the villagers walk up and praise them for finding their lost treasure. They end up taking the treasure back and the two thieves get a party and a large portion of food in return(much to Joker and Spade's disappointment). They then leave the island empty handed.

Episode 08
The treasures Joker goes after are being destroyed one after another. Joker and Hachi think that their next treasure the Silver Egg of the Russian Tsar is next. So in order to prevent it from being destroyed as well they both hastily steal the egg. As they are escaping however, Queen (the third apprentice of Silver Heart) appears and slices Joker's car, Road Joker, in half. She then slices the treasure in two revealing the treasure to be a fake with a transmitter implanted in it. Queen then tells Joker that she will kill him and begins to attack him. Before a fight could break out Silver Heart comes in from Sky Joker and breaks it up. Queen then reveals that Professor Clover told her that Silver Heart is the one who killed her parents and she attacks him. The police rush up at that moment making Queen unable to finish Silver Heart off and she escapes. Joker uses Silver Heart's alcohol and lighter to blow up both halves of the Road Joker making a smokescreen for an escape. Silver Heart then asks Joker to save Queen and tell her she had been fooled by Professor Clover.

Episode 09
Joker tracks down the plane holding the real Silver Egg of the Russian Tsar and encounters Queen who was about to steal the treasure. They end up battling but due to Joker's quick thinking he was able to break Queen's diamond sword by covering it up in alcohol and making it brittle enough to break, due to the cold temperatures caused from the high altitude they were at. Joker then tells Queen the true story of what happens to her parents (Silver Heart actually saved her before the castle she lived in exploded) and Queen finally came to her senses. Their cheerful reunion was short-lived after Queen was knocked off the plane after it suddenly shook. Joker quickly grabbed her hand and hung onto the edge of the wing but due to the wound on his hand that she inflicted on him earlier, he was slowly loosing his grip(the high winds also could've been a factor). Hachi and Roko (Queen's friend, who is a genetically altered dog that can talk) threw a rope at them but the support keeping the rope on the plane fell off causing Joker to slip from the unexpected wait of Queen's body falling. Fortunately Silver Heart shows up in his propeller plane and saves them. Queen apologizes and Silver Heart forgave her, while also making her an official Phantom Thief. Joker, in the end, obtained the real Silver Egg of the Russian Tsar

Episode 10
Joker and Hachi sneak onto the private Golden Express to steal "a top class item" from it. Hachi assumes the treasure they are stealing is the Golden Necklace and sets up a device meant to separate the cars at a junction in the tracks. After setting it up he heads to the train car where Joker is and they head up to the top of the train where they run into Inspector Oniyama. After knocking Oniyama off the train they end up in Kaneari's car (which Kaneari called all the passengers up to) and Joker disguises himself and Kaneari's bear (Kintaro) as the conductor, while Hachi disguises himself as Kintaro. After Kaneari confirms that all of the passengers aren't Joker, he reveals himself and runs to the observation car (where the Golden Necklace is) and gets trapped inside the car by Kaneari. While he is in there, Kaneari gloats at him that he could never open the cage because he needed to turn Kintaro's nose to open the cage. At that moment, the "Hachi" with Joker is revealed to be Kintaro and Joker releases himself and traps Kaneari in the trap instead. Meanwhile, Hachi managed to hop off the train and separate the cars at the junction with a card bomb. He then tries to get himself back on the train to impress Joker but ultimately fails. At the same time a confused Joker is pondering why the observation car is still attached, when he hears Hachi banging along side the train, and Joker pulls him up to safety. Hachi then saw Kaneari still in the observation car and followed Joker to the top of the train confused. They had to hurry before the train tracks converged again and Joker told Hachi: "Jeez, your bungling has made all of this extra work for me." to which Hachi reminds Joker of all the things he did in order to help steal the Golden Necklace. Joker then asks him if he knew what the treasure actually was and he was going to explain when Oniyama climbed back on to the train. Again however, Oniyama is knocked off the train by another sign. After getting rid of the inspector, Joker sees a sign that warns about the cliff at the end of the set of tracks they are on. Joker quickly separates the second to last car and the observation car, the last car turns out to be Road Joker and they drive off with the dining car before careening off the cliff (Joker returns Kintaro to Kaneari first). It is then revealed that the true treasure they were stealing was a top class frying pan for Hachi. Moved by this, Hachi cheerfully makes them both a meal and they dine in the dinning car.

Episode 11
Taking place in a flashback during Joker, Spade, and Queen's childhood, a mutant dog known as Super Dog #101 was created in a laboratory and escapes along with a mutant lizard who wants to destroy the human race. He gets injured, falls into a river, and later gets saved by Joker, Spade, and Queen while they were fishing. They name the dog "Roko" after its love for corn and are told by it about the lizard's plan. They decide to pursue the lizard in order to save the human race.

Episode 12
Joker and Hachi are after the Golden Shachihoko that are on the roof of a ninja castle. While in the castle, Hachi runs into(more like almost killed by) Hyakimaru, a classmate in his ninja school who protected him from bullies. All the ninja's in the castle turn out to be Hachi's schoolmates and they reveal that Hachi was the one ninja failure that comes once in a decade while Hyakimaru is the one ninja genius that come once in a decade. In there conversation Hachi tells them that he is Joker's assistant, they didn't believe it at first but after Hachi continued insisting (Joker remained silent) they began to believe him. Hyakimaru then tells Hachi that he isn't cut out to be a Phantom Thief since he tripped Joker up earlier and to Hachi's dismay. Joker agrees. Hachi then tackles Joker into a room and they get into a mock argument in order to escape. In the chaos, Hachi told Joker to disguise himself as him while he disguises himself as Joker. The ninjas came in and captured Hachi (Joker) while Joker (Hachi) left him there. Angry that "Joker" abandoned "Hachi", Hyakimaru chased after "Joker" while "Hachi" was thrown in a cell. After he managed to lure Hyakimaru outside of the mansion Hachi revealed himself and Joker did the same. They then sat on top of the Golden Shachihokos and used Sky Joker (which was disguised as the moon) to carry them away. Hyakimaru was happy to see how much Hachi has changed and wondered if Joker had something to do with it. Joker then put the treasure in Hachi's room as a joke.

Episode 13
Joker,Spade,Queen and their assistants are all after the "Treasure of Olympus" but Hachi and Roko are stuck outside waiting for Joker and Queen who haven't shown up yet. While waiting, Spade and Dark Eye appear and head for the treasure. Hachi and Roko go after them to prevent them from stealing the treasure before their respective masters show up. Meanwhile Queen shows up and starts to wait for Roko when Shadow Joker appears. He was about to hit her with his attack Bloody Rain but Joker showed up just in time to deflect it. Shadow then runs into the ruins for the treasure with Joker and Queen in hot pursuit. While chasing Shadow, Joker and Queen run into a room where they discover everyone had been turned to stone. Medusa then appears in front of the trio and turns a surprised Queen to stone. Before she could turn them to stone Shadow blinds Medusa by using Bloody Rain and they escape with her pursuing them. They run to a locked door with two buttons they each push a button but it didn't work. With Medusa quickly gaining on them, they frantically press the buttons until the door opened(They had to push both at the same time). The doors shut behind them but before Medusa could attempt to break down the door Silver Heart appeared calling his apprentices names. Medusa appears and quickly turns Silver Heart to stone, before heading back to Joker and Shadow. Silver Heart however was fine since she turned a image gum version of him into stone instead of the real one. Medusa re-enters the bridge before the door to find Joker staring into a mirror. She easily figured out that the mirror was a fake from Joker's shadow, showing it was a clever trick set up by him and Shadow. She happily began slithering up to them thinking she won but ends up falling into a hole that Joker had covered up with image gum (she made earlier when chasing them). Shadow then takes the treasure from her neck as Joker uses Straight Flash to make her fall into the lava below. Before she fully sinks into the lava she begins destroying the ruins and the two Jokers rush for the exit. Since Medusa was killed the others were no longer stone and they all end up following Silver Heart to the exit. The ruins crumble, the treasure is destroyed, and Shadow gets away with the magic crystal that was around Medusa's neck. Everyone returns to Sky Joker and the episode ends as well as the season.

Silver Heart
Silver Heart is the one that inspired Joker to become a Phantom Thief after showing him a miracle. Joker then became his apprentice until he graduated and became a full fledged Phantom Thief. Joker respects Silver Heart and thinks of him as a part of his family. Joker cares for him and even cries when he thinks his past self was dead. Silver Heart also thinks of him as his own and will go to great lengths to protect him such as, shielding Joker when Professor Clover froze time and tried to shoot them. He is also the one that saved Joker after Rose blew up the bridge he was on.

Hachi
Hachi first met Joker when he watched Joker escape the police after stealing the Golden Elephant. They met once again when he discovered Joker was after the same treasure as him, the Dragon Gem. Hachi tells Joker that Kaneari got lost, found his ninja village and tricked the village elder into giving him the Dragon Gem. After that, his village became poorer and poorer, making the inhabitants miserable. After Joker saved him from getting injured, impressing him with a miracle, and letting him take the Dragon Gem back to his village, Hachi asks Joker to let him become his apprentice. Although Joker denied it at first, he ended up giving in after tasting Hachi's cooking. Ever since then Hachi has helped Joker in his various thefts around the world. Even though he won't admit it, Joker values his partnership with Hachi and like wise for Hachi. Joker stole a top class frying pan for Hachi from Kaneari's Golden Express so he can make some "delicious meals". When Hachi tells Joker he is going back home, Joker frantically tries to apologize to Hachi thinking that he was leaving permanently. In the manga Hachi apologizes to Joker for being useless during one of their heists. Joker then says "Idiot, I've never thought of you as useless. Not to mention... If you weren't around I would never get to eat your delicious meals!". Joker even asks Hachi if he wants to go back to his family and looks relieved when Hachi tells him "My place is here! Besides I can visit my family anytime."

Spade
Joker and Spade are rival/friend Phantom Thieves that were trained under the same master. They argue and fight over almost everything especially when a treasure is involved. Despite their rivalry, they will save each other in pinch and are seen working well together when the situation calls for it. Spade is quick to help Joker (usually) when their goals are common such as, Spade suggesting they work together when they were stealing the Scarlet Heart.

Queen
Queen is the third apprentice that trained under Silver Heart. Joker brought Queen back to her senses when Professor Clover tricked her into thinking Silver Heart killed her parents. Even though they consider themselves rivals, Joker gets along with Queen and, unlike Spade, won't hesitate to team up with her when they end up going for the same thing. He even asks her to steal the "Big Wedding Bell" from Kaneari in season 3. They also team up to get the "Gaia Bird" during the Phantom Thief Olympics (Episodes 12 and 13 of season 3).

Shadow
Shadow Joker's actual name is Cyan. Joker (when still in training) snuck out of Silver Heart's cabin and accidentally ran into Cyan and Rose. When talking to them it is discovered that they are twins and Rose has magical powers (She is known as a time witch). Being devious as usual, Joker decided to switch places with Cyan and disguised himself as him, while Cyan dressed up as Joker. Silver Heart came up just as they finished and (mistaking Cyan for Joker) dragged Cyan away. Joker and Rose then headed towards her village where they would discover that the village was in flames, due to Professor Clover's minions looking for Rose. While trying to escape, Joker is shot (giving him that scar he has on his eye) and Rose is captured. Cyan then shows up and tries to get her back. However, he ends up getting shot and thrown into the river. This sends Rose into a state of shock and she uses her powers to blow up the bridge they were on. Joker was rescued by Silver Heart, who told him that they were killed and he sort of forgot all about it until Shadow showed up. Throughout season 1 and 2, Joker and Shadow are more enemies than rivals. However, if the situation calls for it, they will team up in order to achieve their goals (Such as working together to kill Medusa in season 1 episode 13). In season 3 they act more like rivals and even work together to catch a team of imposters.

Hosshii
Hosshii (His actual name is Acrux) is a God-Beast that Joker obtained after stealing back the "Crystal Skull Key" from Phoenix. Hosshii was originally Joker's 1000th treasure but due to Hoshi being very cat-like, he makes the ancient treasure that Pheonix is also looking for as well, it instead. Since Joker is scared of cats he tends to avoid Hosshii and freaks out when he comes into contact with him. Instead of calling him Hosshii, (which is the name Hachi gave him) Joker calls him a "Pseudo Cat". Joker also dislikes that he eats his treasure even though it pops out an egg with a "Guidance Stone" to lead to the ancient treasure or a object that he will eventually need in the episode. It is not clear on what Joker fully thinks of him yet. Hosshii seems to like Joker however.

Phoenix
Phoenix,a.k.a Akai Tsubasa, is a alien from space that got stranded on Earth along with his navigator Acrux (or Hosshii). Phoenix likes Joker's view of things and is impressed by the miracles he can create. Joker refers to Phoenix in three ways, Akai Tsubasa (Rarely), Phoenix, and yawning-jerk. Despite their bantering, Joker sees Phoenix as a strong rival (like Spade and Shadow) and refuses to lose to him. Joker was agitated at Phoenix because he couldn't figure out why he could fly, use magic and other things. After finding out that Phoenix was an alien, he shrugged it off stating it makes sense since he is an alien. At the end of season three he gives Phoenix a advance notice for his treasure.

Trivia

 * Joker owns a white Koala he stole in volume 2. No one knows what happened to said Koala in the later volumes, though.
 * Volume 2 also reveals he has a deep fear of cats. While it isn't explained in the manga, Doubt turning into a cat (which happened solely in the anime) and chasing him in episode 5 of the anime could be the origin of that phobia.
 * His catchphrase in the manga is "Au Revoir" (goodbye in French), and he is shown to know French (although whether he is fluent or not remains unknown) as he is seen reading a book in French in volume 7.
 * While his actual nationality remains unknown, it is believed that he is either from England or North America.
 * Although the author refused to give his actual age (because he has no idea, either), he said in an omake that he is somewhere between the end of middle school and high school (13-14 ~ 15-16)
 * In episode 4 of the anime, it is revealed by Hachi that Joker has a cavity on his back tooth.
 * His favorite food is curry, though he also enjoys other kinds of food and isn't that picky.
 * In the second season, it was revealed that he has Image Gum in one of his back teeth
 * In the manga, it is revealed that Joker's favorite foreign show is MacGyver, a American show about an agent that uses science and brains to thwart his enemies instead of a gun.
