"Karate Guy"
"Karate Guy" isnt his actually name but a nickname he picked up after loosing a bet and having to wear only his gi for 30 years. His real name is a secret, so he embraces the name "Karate Guy" or sometimes just "K"or "KG".

KG is actually a human, but he was not born on Earth. His current appearance is the direct result of his intense intergalactic martial arts training. He does not actually practice Karate either but an Ancient Alien form of martial arts known by many names throughout the Universe. However, the style does look and perform much like our Earth Karate, utilizing power chops and kicks that could level a mountain when mastered.

K is a good guy for the most part and 2nd in line to be Grandmaster, now that he has earned his Rainbow belt. He has set out on a journey to take his training to the next level and make the style his own. He uses martial arts to fix ALL PROBLEMS, if a cat is stuck in a tree he will more than likely karate chop it down.
