The Ultimate Imposter is a student of Hope's Peak Academy's Class 77-B, and a participant of the Killing School Trip featured in _Danganronpa 2: Goodbye Despair_. They impersonate Byakuya Togami as the Ultimate Affluent Progeny. The Ultimate Imposter's real appearance is that of a person with long, black hair and green eyes with a heavy build. Their age and gender is unknown, but they are able to give off a largely male impression while disguised as Byakuya and even mimic his voice 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. Their true personality is also somewhat unclear as they spend most of their time mimicking someone else's behavior. However, they speak briefly without disguise and it's implied that their real nature is polite and meek. Most notably, they appear to be truly kind and caring, but also quite serious. 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 take other people's data and learn it so they can impersonate them flawlessly. No one can tell the difference between the Ultimate Imposter and the real person that they impersonate. 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.
