Double was the Quirk used by Jin Bubaigawara and the Nomu Mocha.
Description#
Double allowed the user to create a copy of anything, two at a time, through touch.
With Double, Jin could produce replicas of anyone to provide support in numbers. He did this by creating a dark-coloured, viscous fluid from his hands that formed into the person in question. In order to conceive a perfect clone, Jin required knowledge of precise measurements and physical features of the person or object he was replicating. Doubles possesed the same personality and abilities as the original, making it hard to distinguish them from the real person at a first glance.[1] The copies only recalled the memories of the last time they interacted with Jin himself.[2]
Jin had a limit of creating only two doubles at a time. However, because Jin was able to copy himself and his copies also had access to Double, he was theoretically capable of producing infinite replicas of himself by letting his doubles duplicate themselves further. His creation speed was much faster for himself than for others.[2] Even half-destroyed doubles could keep multiplying themselves as long as their arms were intact. This gave Jin the manpower to easily carry out a large task or several smaller ones at once, provided that his doubles cooperated with him. Skeptic claimed that Double could even replicate dead people.
While Jin himself didn't suffer any repercussions from his doubles getting destroyed, he was still capable of detecting their destruction, even if they were far away from his location.[3][4]
With Mocha's duplicate of the Quirk, it is unknown whether the Nomu carried the exact same strengths and weaknesses of Twice's Double. However he was shown creating a clone of his master, Kyudai Garaki, by releasing the same viscous fluid from his ears. The doctor's clone also melted away after being drilled in the arm by another Nomu.
Weaknesses#
The copies were less durable and powerful than the real thing, dissolving into a viscous mud-like liquid after receiving enough damage, and a second copy was apparently even more fragile. According to Jin, physical injury equivalent to a broken bone was usually enough to extinguish a clone.[5]
Jin needed a flawless image of whatever he planned to duplicate stored within his mind, so the measurements and physical features had to be extremely accurate. Without a perfect image, all Jin would get was a poorly formed copy that wouldn't last long.[1] Therefore, every time a person undergoes any physical change, Jin had to take the measurements again.[6]
When it came to trying to create objects, apart from a clear image, Jin also seemed to need data about the basic composition and structure of the object in question, otherwise the copy would be defective and decompose.[7]
When creating clones of other people, they would be created to match their last "point of measurement", meaning that acquired injuries or conditions would be passed from the original to the clone as well. This is seen with a clone of a fatally injured Himiko Toga, as well as a clone of Mr. Compress still missing his left arm and having to rely on his prosthetic.[8]
Furthermore, people cloned with Double possess complete autonomy and freedom of action, so even if they know they're copies, they don't feel the need to follow their creator's orders if they don't share a common goal or are afraid of being destroyed.[9]
It can get to the point where the clones can eventually turn against the user, with the user unable to undo them and having to wait for them to be damaged enough to disappear on their own.[10]
Usage#
Double had a major role in shaping Jin's character, to the point of making him insane. In the past, Jin initially used Double in order to cope with loneliness, since he had no friends or relatives to interact with, but he eventually devolved into criminal life, committing theft and robberies alongside copies of himself.
Jin would abuse his copies to act as servants and follow his bidding. However, due to Jin's doubles sharing the same personality as the original Jin (who was lazy and overbearing), they disliked the slave work they were put in and ended up rebelling against their creator, attacking Jin with a knife and then tying him to a chair. Because each clone believed they were the real Jin and the others were fakes, they then engaged in a bloody brawl that lasted for nine days, and Jin could only watch in horror as his own clones kept attacking and killing themselves repeatedly. Once it finally ended, Jin was left unsure as to whether he was the real him or a clone that killed the original.
As a result of this traumatic event involving his Quirk, Jin became afraid of using his ability on himself again. If he was left through long periods of time without covering his face with a mask, Jin, as he claims, will end up splitting himself, although it's unknown if this phrase referred to an actual physical consequence or just a metaphor for his dissociative identity disorder. During the Meta Liberation Army Arc, due to a strong desire to protect his comrade, Himiko, and receiving multiple injuries, which confirmed that he was, in fact, the original and not just a clone, Jin overcame his trauma, becoming willing to duplicate himself once more. His clones could also be used for blood transfusion, as shown when Jin created a clone of Himiko to perform one and make up for the blood she had lost. Also, as shown by a Dabi clone's fight with Shota Aizawa, and later noted by Kyudai Garaki's clone, doubles were not melted by Erasure.
Having no qualms in replicating others, Jin was a very useful asset to the League of Villains as his Quirk granted him a way to temporarily increase their numbers if they found themselves short-handed, giving the organization more "subordinates" to attack or distract enemies. This also helped prevent actual members of the League from being killed or caught and arrested by sending clones of them into battle. Giran claimed that Jin could potentially take over the entire country with his ability if used correctly. Because of this, Tomura Shigaraki considered Jin a vital part of his villainous goals, and even the Meta Liberation Army had shown interest in drafting Jin into their own ranks.[5]
During the buildup to the Final War, Himiko was given a vial of Twice's blood by Dabi,[11] which she ended up using, utilizing Twice's Sad Man's Parade against the Heroes, as well as a deadlier version dubbed "Sad Man's Death Parade", and a version involving Doubles of other people dubbed "Sad Man's Legion".
Jin had doubled the following people:
- Himself[10]
- Dabi[3]
- Mr. Compress[9]
- Himiko Toga[12]
- Kendo Rappa[12]
- Tomura Shigaraki[13]
- Spinner[14]
- Re-Destro[15]
Jin usually reassured copies that they're nothing more than that, probably to prevent them from rebelling or feeling confused.
The Nomu Mocha used the Quirk to double the following people:
Kyudai used Mocha's Double to create a clone of himself to perform his physician duties at Jaku General Hospital while the doctor was busy with Tomura's surgery.
Named Ultimate Moves#
Twice#
Sad Man's Parade: Twice creates doubles of himself, then the doubles created doubles of themselves, then those doubles created doubles of themselves. This cycle continued, resulting in thousands of doubles of the user.[7]
Himiko Toga#
Sad Man's Parade: By copying Double, Himiko is able to replicate Twice's signature Ultimate Move, swarming her opponents with countless Doubles of Twice.[17]
Sad Man's Death Parade: Himiko's deadlier version of Sad Man's Parade. Fuelled by rage, she summons countless Doubles of herself transformed into Twice with the express intent of killing anything in her path.[18]
Sad Man's Legion: By using her Transform Quirk to duplicate Twice's Double Quirk, Himiko is able to create a legion of clones that take the appearance of several Heroes and Villains, whose blood was taken from the battlefield of the Gunga Mountain Villa Ruins.[19]
Trivia#
- This Quirk was functionally similar to Clones, as they both revolve around creating duplicates out of a viscous liquid. There are a few key differences, though:
- Ectoplasm can only make replicas of himself, whereas Jin was capable of making doubles of anyone, including himself as well.
- Ectoplasm can create up to 30 (36 at best) clones, whereas Jin was limited to only 2 Doubles of other people.
- Ectoplasm's clones retain the 30-36 clone limit, whereas Jin's doubles don't retain the 2 double limit, bypassing it.
- Ectoplasm can create a massive clone of himself, whereas Jin had not shown such an ability.
- In the original release, despite creating a copy of Himiko in the Shie Hassaikai Arc,[12] Jin later claims in the Meta Liberation Army Arc that Himiko never allowed him to take measurements of her.[20]
- This was amended in the Volume 24 release, with Jin stating he had to re-measure her because her body had grown again since then.
- This Quirk was also similar to Creation, as they both enable the creation of objects and both require extensive knowledge of the object's structure to do so. There are differences though:
- Momo Yaoyorozu cannot create living organisms, whereas Jin was able to do so.
- Momo can create as many objects as she wishes so long as she has enough fat stored in her body, whereas Jin could only create two objects at any one time.
