Apperance

On the character select screen Crispin appears to be a normal zombie that has been set ablaze. However when you begin playing with him on Arcade mode he is badly burnt but his body is not on fire.

Trivia

When character ablities are turned on, Crispin is virtually fireproof due to his high amount of Fireproof Stats.
