Kokichi wears a white jacket of sorts with white pants to match, and a checkered scarf that stays around his neck. He's 5'1, 97 pounds, and his strength reflects his size. He's fairly weak, but as a trade off he can easily squirm and slither around like a sneaky little kid. Also, he's quite good at hide n' seek. He has purple eyes, and his hair is dark purple/black.
Ultimate Supreme Leader
Mischievous. Childish. Deceive. Most importantly, a liar. He acts like a child, spurts lies left and right, can be moody and also manipulative. He gets enjoyment out of others' suffering and finds it amusing.
Aside from what was mentioned above, Kokichi was the leader of a small group that would cause minor misdemeanors and pranks. Known as D.I.C.E., the ten members of this mentioned group are said to be like family to him. Every crime they commit was just "laughable crimes" and small things here and there, but nonetheless would cause some sort of disruption.
