Street Fighter Alpha
Dan is introduced in "Street Fighter Alpha" and "Street Fighter Alpha 2" as a martial artist who developed his own fighting style called "Saikyō-ryū", "The Strongest Style", despite the considerable lack of power in his techniques. During these two games, Dan seeks to defeat Sagat to avenge his father's death. While Dan is an unlockable character in "Street Fighter Alpha", in following games he is already available. By "Street Fighter Alpha 3", Dan has succeeded in his quest (As Sagat purposefully threw the fight out of pity) and seeks to perfect and promote his fighting style. In this game, he also declares himself the mentor of the fighter Sakura Kasugano and is revealed to be one of Blanka's friends.
