Spike

Spike is the quaternary protagonist in the series. He likes to swordfight, as the scar on his cheek. He hates a guy named Serpent because his great great grandfather family long ago, unfairly killed Spike's great great grandfather in a swordfight. Ever since, the two families have always made their second-born child the swordfighter of the house. Enough fancy lore, Spike also likes mint chocolate ice cream. Spike's appearance is black sawblade hair (that's what the creator calls it), a light gray shirt with black pants, and gray shoes. And most importantly, the scar on his cheek. Spike is VERY self-conscious about his scar, and gets really mad when people make fun of him for it. He has an older brother too, his name is Frank, and he is a very VERY strong Russian dude you would not want to mess with. Also yeah Spike's Russian too. But Spike has a MUCH higher pitched voice and talks a little differently.

Spike's first appearance was in the animation: Spike hurts himself, where Spike introduces himself and hits a dummy which spins around and the arm falls off, hitting Spike right in the face.
