Nonagon is a nonbinary character, competing in Animatic Battle, on a team called DIET.

Nonagon is… well, a nonagon; a shape with nine sides. Nonagon has no legs, but they have arms; usually outstretched in an A-pose. Nonagon always has a big smile on their face; never actually opening their mouth, even when talking. They refer to themself and others EXCLUSIVELY in third-person.

Nonagon seems to be a very powerful entity, but it’s unknown what they’re capable of.
