Rotter has a small stature, with his hair sticking around his head like a small crown and a large grin always placed on his face. He wears a small Parthevian uniform.
Rotter seems fairly confident in his abilities, boasting about it in battle and seems to have fun toying with his enemies. He also shows a soft side to himself, crying over his rat friends when most of them got destroyed by Drakon's Household Vessel, and he swore he wouldn't forgive Drakon for hurting his friends.
