Spike is a slothful, listless, indifferent, and lazy person. He passes the vast majority of his time on the Bebop lounging, watching TV, or sleeping. In a few rare occasions, he is also seen reading or practicing Jeet Kune Do, a martial arts practice he is very skilled in, being among other things passionate of Bruce Lee films. He is also a heavy smoker, being shown with a cigarette in his mouth in practically every shot. Spike is rarely seen excited about something.
