Masutatsu Oyama is a legendary master of martial arts, and is the ancestral progeny of Kyokushin Karate, the strongest form of karate. During his era he went completely without rival within the realm of karate as a whole, and may very well be the single most powerful human martial artist of all time, due to his ridiculous striking force which was enough for him to be nicknamed "God Hand", as a testament to his ability to fell nearly any opponent with one strike. Masutatsu's power comes about as a result of the Xuan Wu fragment he inherited as chosen by fate to be a champion of the martial arts to an extent like that of no other.
