Killer wears a full face mask helmet. Because he is insecure and hates his laugh. He never laughs and will kill you for laughing at his laugh. Killer is a man of few words. Unless you are friends or a crew mate he will not say much. He is the first mate of the Kid pirates. He is best friends with Eustass Kid, the captain. He likes to play the drums, cook, and research history and facts. Killer is very calm and analytical.
