Ultimate Impostor

Ultimate Impostor is a character from the Danganronpa 2: Goodbye Despair game.

Ultimate Impostor is a student of Hope's Peak Academy's Class 77-B, and a participant of the Killing School Trip. They impersonate Byakuya Togami as the Ultimate Affluent Progeny.

In the Heroes Coalition fics, Ultimate Impostor is spared from canon fate. Ultimate Impostor is a member of the Heroes Coalition as a Solo Hero.

Appearance
The Ultimate Imposter's real appearance is that of a person with long, black hair and green eyes. Their age is unknown, though they appear to be in their early twenties. They have a very heavy build; despite this, they can fool others with their disguises.

Their gender is unknown, but they are able to give off a largely male impression while disguised as Byakuya and even mimic his voice and poses perfectly. In Danganronpa 3, their real voice is quite deep and masculine. However, originally in Danganronpa 2, the brief glimpse of their apparent real voice sounded notably different, more high-pitched and rather gender neutral. The Imposter also refused to go swimming in front of others, which implies that removing their clothes would reveal their true gender.

Personality
Ultimate Imposter's true personality is somewhat unclear, because they spend most of their time mimicking someone else's behavior. However, during chapter 6 of the second game, they speak briefly without disguise and it's implied that their real nature is polite and meek. In Danganronpa 3, they're shown to have a quite serious personality.

Most notably, the imposter appears to have a truly kind and caring personality. They impersonated Ryota Mitarai so that the real one could focus on making anime, as well as get some rest, and kept checking on his well-being even after a year of impersonating him. The imposter is also shown to be smiling in a friendly manner and being protective and supportive to others even while acting as the cold and arrogant Byakuya Togami. As part of their Byakuya impersonation, they act arrogant, rude and somewhat bad-tempered, but they're also reliable and feel responsible of others' safety.

The imposter enjoys their build, which appears to be their aim, as they've stated to have intentionally sculpted their physique to be that way (while acting as Byakuya, they appear condescending towards "skinny people", though this is most likely part of their act). They have a strong liking for food, especially fast food; while they normally appear attentive, they are rather easily distracted by food. They are shown to be surprisingly passionate on the topics related to food and eating, such as body fat percentages, the amount of energy coming from specific foods, and fast food restaurants. They explained that, since virtually all fast food restaurants serve the same kind of food, it gives them a sense of security to keep being around something familiar.

Due to their nature as an imposter, they have a lack, if not absence of, self-esteem. Because of it, they feel very lonely as if they do not exist. They simply want to exist and live a normal life, but they believe they cannot unless they assume someone else's appearance and "disappear" if they're found out. They describe their life as a living hell, as they're in constant need of affirmation and they have to lie to other people. Because of this, they preferred not to become close with other people, thinking that only thing in the world you can truly rely on and believe in is "fats and sugars".

At one point, in Danganronpa 2, they ask if Hajime Hinata likes being around them, and they seemed very happy when Hajime answers that they are friends. After spending time with Hajime, they are convinced that they really do exist, and they decide they don't want to lie anymore and wish to live as their true self with their friends. Despite having better sense of self, it's shown in Side: Hope that they still prefer being in disguises (albeit only physically).

Abilities
The Ultimate Imposter doesn't have a name, family register, relatives, and anything that could link them with their true identity. In order to have their existence acknowledged, they took other people's data and learned it so they could able to impersonate them flawlessly. They could impersonate the person in question's voice and personality perfectly.

No one could tell the difference between the Ultimate Imposter and the real person that they impersonated. According to Monokuma, even their noticeably heavy body build does not affect their ability to fool others. This, along with the fact that they are capable of changing their appearance extremely quickly without anyone noticing, implies that their talent is near superhuman.

In Danganronpa 3, all of Class 77-B and Chisa don't recognize the real Ryota Mitarai's true appearance until they accidentally met with Chisa, who wondered how the real Ryota could lose his weight in a very short time.

In Despair Arc #09, they revealed to their classmates that they were a fake version of Ryota and decided to become themselves afterward.

Trivia

 * In their Free Time Events, the Ultimate Imposter implies that the reason they chose to put on so much weight was in order to ensure survival should they ever have to withstand extreme cold.
 * Like Junko and Izuru, the Imposter has no listed likes or dislikes. This may be due to their background where they have nothing that pertains to their true identity.
 * Their title was translated as the Ultimate Swindler instead of Ultimate Imposter in the PC version of the English localization of the second game's ending credits, despite the fact that they were referred to as Imposter earlier in the game.
 * In Danganronpa 3: The End of Hope's Peak High School, the voice actor portraying both Ryotas, Kanata Hongō, also portrayed Makoto Naegi in Danganronpa: Kibō no Gakuen to Zetsubō no Kōkōsei THE STAGE (2014).
