Might Duy

, often referred to as the, was a genin-level shinobi of Konohagakure and the father of Might Guy.

Background
Dai spent his entire career as a genin, causing many to look down upon him. After twenty years of training, Dai learned how to use all Eight Gates. He later had a son, Guy, who showed little progress himself as a shinobi. When Guy began feeling sorry for himself, Dai scolded him for not having faith in himself. Later, Dai taught Guy how to use the Eight Gates. Some time afterwards, Dai rescued his son Guy and his team-mates, Ebisu and Genma Shiranui, from the Seven Ninja Swordsmen of the Mist, giving up his life by using all Eight Gates.

Personality
Despite his status even in adulthood, Dai was a proud and upbeat man. Like his son, he was overzealous, regularly using a "nice guy" pose. He believed strongly that one must have confidence in themselves in order to achieve anything. He also believed that one's true youth only ends when one turns their back on their beliefs and joy. Dai had a very strong relationship to his son, constantly pushing Guy to be his best and lifting his spirits when upset. A committed man, he had no fear in facing his enemies.

Appearance
Dai was a tall and well-built man with high cheek-bones, a somewhat bulbous nose, dark hair and thick eyebrows. His hair was cut in a bowl style that was combed to his left and also sported a bristling moustache with a small goatee and stubble. He wore a green jumpsuit, orange striped leg warmers, and a scarf around his neck.

Abilities
Dai possessed a superb physical condition and capabilities in taijutsu. Having spent twenty years perfecting it, Dai mastered all eight of the inner gates. While admitting to it being his only technique, Dai was able to fend off the entire Seven Ninja Swordsmen of the Mist with it and was confident enough in his abilities to teach it to his son.

Legacy
Dai's sacrifice left a huge impression on Guy. He continued his father's belief of maintaining one's youth. Guy also formed a similar relationship to his student Rock Lee, as he did to his father, yet in reversed roles.
