Fizzarolli is a clown Imp wearing a jester outfit. His arms and legs are mechanical prosthetics. He used to be childhood friends with Blitzo, but now hates him for causing the accidental fire that killed Fizzarolli's foster parents and cost him all of his limbs.
Blitzo is a tall Imp, and leader of the Immediate Murder Professionals (IMP for short). He hates Fizzarolli, and believes himself to be innocent, in spite of any evidence to the contrary.
