Kaiser is a small plushie with blue eyes and blonde hair. He has a mullet with blue streaks at the end of his hair (rat tail haircut). Kaiser also has blue rose tattoos on his neck, turning into chain-like intertwined thorny stems down his left arm culminating in a crown with a keyhole on his left hand. He's an arrogant young man who has a superiority complex. Even though Kaiser is arrogant and rude, he knows when to control himself around people who are definitively better and superior to him.
