Jin Bubaigawara

Jin Bubaigawara (分倍河原仁), also known by his villain alias Twice (トゥワイス), is a villain affiliated with the League of Villains and part of its Vanguard Action Squad. He and the rest of his team serve as the main antagonists of the School Trip Arc.

Appearance
Jin is an average adult man with light spiked hair and a large scar on his forehead. His civilian outfit consists of a tank-top and a dark-colored coat; he carries his mask around with him to wear it when he feels he is going to "split".

In his villain costume his entire body is covered by a black-and-grey, full-body suit that hides any distinguishing features about his body. He has red and blue wristbands.

Personality
Jin has an explosive and lively personality. He appears to have a contradicting personality, insulting Dabi one moment then praising him in another. He is also contradictory in his speech, asking Himiko if someone hurt her when she was happy, and exclaiming it was cold when hit by Shoto's fire.

Twice believes that understanding your own identity is the most important aspect in life.

Behind his outgoing and contradictory personality, Twice suffers from dissociative identity disorder due to the history of his Quirk that drove him to insanity. When his mask is off, he shows a strong sense of self-conflict over who he actually is. Jin is also unsure whether he is the original Jin or if he is a clone that killed the original.

History
In his past, Jin cloned himself over and over until he had created a team of himself. Jin made the clones do everything for him and he was their king. However, the clones began claiming that they were the original, which resulted in an argument as to who was the real Jin. The argument resulted in the clones and the real Jin all fighting each other in a brutal brawl; Jin suffered an injury to his head as a result of this fight which left a scar on his forehead. The brutal fight dragged on for a week and two days, and at the end, the clones killed all of each other and they vanished, with the remaining one unsure whether he was the original or not.

School Trip Arc
Jin joins the other members of the Vanguard Action Squad as they look down at the camp where the U.A. High students are staying.

The Vanguard Action Squad attacks the training camp on the night of the third day, filling the forest with poisonous gas and fire. After Dabi's clone is defeated by Shota Aizawa, Jin begins to insult Dabi's clone saying that he was weak. However, when the real Dabi appears, Jin quickly retracts what he said and begins to praise him, though Dabi appears not to notice his previous insult. Dabi then orders him to make two clones of him so that he can resume his fight, and Jin happily complies. He sends the Dabi clone to attack the students at the camp facility, serving as a distraction for the Pro Heroes Sekijiro Kan and Shota.

Eventually, Mr. Compress manages to capture Katsuki Bakugo and informs Dabi along with the rest of the Vanguard Action Squad. At the rendezvous point Dabi notes that their only action now is to wait for their fellow villains. However, he states that there are no gas or walls of fire to make the escape better. He relents and accepts that plans do not always go accordingly, and looks at the bush Yuga Aoyama is hiding behind, much to Yuga's fear. Dabi prepares to go and check but is stopped after Jin informs him that they must also call back Nomu since it only responds to Dabi.

Dabi and Jin wait for their fellow villains to reach the rendezvous point. When Himiko Toga arrives, Dabi asks how her mission went, and she replies that she could get the blood of only one person. Jin is unimpressed and wonders why Himiko is excited, to which Himiko replies that she found a boy she is interested in. As Himiko and Jin converse, Dabi orders them to keep quiet. Dabi sees something approaching them; Izuku Midoriya, Mezo Shoji, and Shoto Todoroki smash Atsuhiro onto the ground and then apprehend him. Dabi is seemingly displeased while Jin contradicts his knowledge about the identity of the Heroes.

After Dabi attacks with his flames, Jin appears behind Shoto and attempts to attack him, only for Shoto to block him with ice, which sends Jin reeling. Jin gets back up and tries attacking again, but Shoto holds him back. Soon, Kurogiri arrives in order to retrieve the Vanguard Action Squad. Jin stops his battle with Shoto, jumping into Kurogiri's Warp Gate and successfully teleporting away from the training camp.

Hideout Raid Arc
After completing the mission, Jin is present when Tomura Shigaraki talks to the restrained Katsuki inside the League of Villains' hideout.

After Katsuki and the League of Villains watch a video clip of U.A.'s public apology, Tomura understands why society is criticizing U.A. for their failure and that is because the current Hero society is not just. Shuichi Iguchi agrees that the current Hero society is not just since the modern Heroes are only doing their job for compensation and not out of selflessness. Tomura explains that the League of Villains are fighting for a just society and intends to win this battle. Tomura orders Dabi to remove Katsuki's restraints, although Dabi is unsure since Katsuki might attack; Tomura wants to treat Katsuki as an equal and is aware that Katsuki knows he has no possibility of winning. Dabi has Jin remove the restrains. As Jin removes the restrains, Atsuhiro apologizes to Katsuki for forcibly kidnapping him and explains that the League of Villains are not just a group of hoodlums perpetuating crimes nor did they casually abduct him; he goes on by saying that everyone in the League of Villains is shackled by the current society and hopes that Katsuki understands their discrimination.

Katsuki's restraints are removed. As Tomura approaches him, Katsuki attacks Tomura with his Explosions and tells the League of Villains that it is pointless to try and make him change his mind as he has already been won over by the way All Might looks when he wins. Katsuki says that from the beginning he has dreamed of becoming a Hero and surpassing All Might and nothing they say will change that.

Suddenly, All Might breaks in while Kamui Woods swings in and restrains Jin and the other League of Villains with his Lacquered Chains Prison.

Suddenly, Artificial Humans appear from a mysterious back liquid which takes the Pro Heroes off guard. Jin along with the League of Villains are teleported by the mysterious black liquid to the League of Villains' destroyed warehouse where All For One is.

All For One forcefully activates Kurogiri's Quirk, creating a portal for the League of Villains to escape through. Seeing that Katsuki will not willingly go with them, Jin, Atsuhiro, and Himiko battle Katsuki, who fends them off with Explosions.

After Katsuki is rescued by Izuku, Tenya, and Eijiro, Atsuhiro along with Kenji and Shuichi hatch a plan to recapture Katsuki. Kenji magnetizes Atsuhiro and Shuichi pushes him, causing Atsuhiro to fly at Izuku's group. Suddenly, Mount Lady uses Titan Cliff and intercepts Atsuhiro, which causes them to smash into each other, preventing Atsuhiro from getting to the students. Kenji and Shuichi prepare to throw Jin, but Gran Torino blitzes them, knocking them unconscious.

The unconscious Jin along with Tomura and the Vanguard Action Squad are magnetized by Kenji's Quirk, courtesy of All For One; Jin is forcefully sucked into Kurogiri's Warp Gate and is teleported away.

Two weeks after the battle between All Might and All For One, Twice recovered and the League of Villains scattered to prevent the Heroes and the Police Force from finding them. Jin began living in an apartment in Kanagawa Prefecture. He goes outside and witnesses a crime committed by Team Reservoir Dogs. Giran calls and informs Jin that Tomura wants the League of Villains to gather once more, warning Jin not to do anything crazy. After the phone call ends, Jin begins to start splitting into two but stops this by putting a mask over his face. He looks back at the crime scene only to find that another group of villains has defeated Team Reservoir Dogs. Jin wonders what he should do now.

Internship Arc
Jin leads Overhaul to a meeting with the League of Villains. He is later shocked when Overhaul kills Kenji Hikiishi.

When Overhaul's subordinates arrive, Jin is suprised and notes that he made sure that he was not being followed by anyone, though Tomura assumes that it must be part of someone's Quirk. He holds an injured Atsuhiro and tells Overhaul that he will kill him. As Overhaul leaves the scene, a furious Jin asks Tomura to let him take responsibility, only for Tomura to deny him.

In his meeting with Tomura, Chisaki requested Himiko and Jin to join as temporary members, and later has the two impede the heroes infiltrating the headquarters. Jin made a clone of Himiko, which she used to attack Rock Lock who destroyed it. After Joi Irinaka separates the heroes, Jin and a clone of Rappa confront Sir Nighteye.

Quirks and Abilities
Double: Jin's Quirk can clone things, making one into two. Jin normally uses his Doubling to create clones of himself and others; the clones have the same appearance, personality, and Quirk as the original. The clones have durability as they need to take a certain amount of damage before they disappear; when they take too much damage, they turn into some kind of liquid and evaporate. Jin is aware of when a clone is destroyed.

A drawback to this Quirk is that Jin has little to no control over his Doubling. JIn is unable to control the clones because they have their own autonomy. Jin's Quirk has given him a contradicting personality, where a voice in his head contradicts whatever he says. Jin greatly struggles from involuntarily splitting himself into two; this weakness is countered by wearing a mask as it allows him to stay as one entity.

Equipment
Measuring Tapes: Inside Jin's wristbands are measuring tapes of some extremely sharp material, which, by grasping it with two hands, he can use as a weapon. With it Jin manages to cut a thick spike of ice.

Chisaki
Jin is the one who introduces Overhaul to the League of Villains. Initially, Jin is impressed by Overhaul's display against Team Reservoir Dogs and decides to recruit him.

His impression of Overhaul changes drastically when Overhaul kills Kenji and destroys Atsuhiro's arm. Jin holds a grudge against Overhaul for what he has done to the league, vowing it is his responsibility for what happened and he would be the one to kill him.

Kenji Hikiishi
Both are members of the League of Villains. Jin becomes indirectly responsible for Kenji's death when he brings Overhaul to the league. Jin feels remorse for Kenji's death at the hands of Overhaul and vows to take responsibility of killing Overhaul.

Atsuhiro Sako
Both are members of the League of Villains. Jin becomes indirectly responsible for Atsuhiro losing his arm at the hands of Overhaul. Jin protects his fellow member, vowing to kill Overhaul for what he did to Atsuhiro and Kenji.
