In one of its winposes they looks around to make sure they isn't being seen, jumps into the air, transforms their hands into wings and flies away while shouting 'woohoo!'. Twelve isn't without quirks in its personality, however. In its rival battle against Necro however, Twelve is shown speaking in a normal manner. Their winquotes imply a simplistic, aggressive and even thuggish personality, akin to that of an arrogant foot soldier. Beyond this, Twelve is only capable of expressing themselves in a binary code cypher (00001 = A, 00010 = B, etc.).

Twelve bears no active personality, usually copying their opponents' quips and uttering 'target' and 'complete'. Though it can alter its shape, the transformation is not perfect: they will maintain its coloring even on details such as clothing. Its head is equally smooth and sloped like a helmet with a pair of thin, red eyes, covered by black veils, set above an expressionless, narrow mouth. Its body is generally smooth and featureless. While they can theoretically take on virtually any form, Twelve's default appearance is a milky-white semisolid male humanoid.
