Carter Hargrave is the Grandmaster and founder of a new martial art style. Well its new in the sense that it was founded in 1992, so in martial arts time it is new. The style Carter Hargrave founded and expert in is American Combat Kempo Karate. What that is in a nut shell is a modern self defense system that Hargrave devised to allow people with no training whatsoever, and those with physical limitations to be able to defend themselves in about six months.

He also is a descendant of the famous Bruce Lee School in California.
