Saitō Musashibō Benkei (西塔武蔵坊弁慶)
A sōhei / warrior monk who lived in the Heian period.
His birth was said to have been divine according to folklore. Some say he his father was a God.
He was called Oniwaka (鬼若 "demon/ogre child" and grew up to being 6 ft 6 inch.
He fought alongside Minamoto no Yoshitsune, and to defend Koromogawa no tate castle, he was said to have defested 300 men on his own on a bridge.
Benkei is, though, by some in Esoteric Buddhism to he an Dharmapala (protector of the dharma) even after his death, as he was on his life, and thereby a Saint.
Personally, he is a figure I have always looked up to as a Buddhist and as one who practices martial arts.
