Beast

"Beast" (ビースト, Biisuto) is the name given to Amon's other persona, though rarely takes a turn in using the body, having no purpose when he has control over the body, making him wander aimlessly. Beast's existence isn't well known, due to Amon having control of the body more often than Beast himself, and the fact the two share no conflict over who controls the body.

Appearance
Beast has the same physical appearance as Amon, and same hair, though his eyes are noted to have faint black pupils, and visible iris, unlike Amon's blank eyes, showing Beast is capable of sight. The noted difference between Beast and Amon is that Beast doesn't wear the hoodie on and that he dislikes the bandages covering his face, due to they are uncomfortable and feels like they're choking him, instead wearing a gas mask, or simply loosen the bandages when he doesn't have it.

Personality
Unlike Amon, Beast is much more silent, and only seems to talk when he is spoken to, though most of his comments involve sarcastic or half hearted replies, as well as speaking in an emotionless tone, almost as if he doesn't care about what's going on. However, Beast does show concern towards Amon, even admitting he sees him as a brother to him, as he is the only one he can always talk to.

Trivia

 * Beast's appearance is based off of Nagito Komaeda from Dangan-ropa.
 * Amon calls Beast by how he calls others by what they are, rather than who they are.
 * Beast and Amon are considered brothers and/or twins.
