Almost nothing is known about about Brian's past. Being adopted at a young age, the only thing that Brian has learned about his kind is prejudice. He has been a loner all his life, not because of his lifestyle, or his social status, but because of his species. No one understands that skunks don't always smell, but it's just a defense mechanism. Brian has always been a laid back kinda person, so it's doesn't bother him much when everyone around him start holding their noses and start walking away. His best friend Kenny seems to be the only that understands him.
The only thing that seems to be a link to his past, is his supreme ability in the martial arts. He teaches his own dojo and even taught Kenny a few moves. But does this mean about his past?
