John-Jitsu
John created his own style of martial arts, John-Jitsu. He borrowed heavily from Japanese monster movies (Godzilla, Rodan, Mothra, King Kong vs Godzilla, Mothra vs Godzilla, etc.), Universal monster movies (Frankenstein, Bride of Frankenstein, Dracula, The Wolf Man, Abbott and Costello meet Frankenstein, etc.), and Moe Howard. His signatures moves included rearing up and shooting flames from his mouth, implied threats ("We belong dead."), and direct threats ("Why I oughtta!"). John-Jitsu was so effective that actual physical force was rarely needed, but when it was, it was probably two fingers to the eyeballs. He was a traditionalist.
