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, having realized through Dan how far gone a person can be for revenge, purposefully threw the fight) 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. Dan also appears in the console versions of
Street Fighter IV, entering the tournament in an effort to make his Saikyo-style more popular. However, his plan fails due to lack of publicity used for his dojo, he didn't pay his phone bills and when he made his commercial to promote his dojo, he forgot to put the address to his dojo. Dan is used as the "dummy" opponent for the Challenge Mode in the home versions. Prior to being released as a playable character for the fifth season of
downloadable content in
Street Fighter V, he provides descriptions of items that players can purchase from the in-game store, occasionally breaking the
fourth wall. In the game's story, Dan may have won in a certain world martial arts tournament legally off-screen, but is still dissatisfied about still lacking of students in his dojo. However, thanks to Sakura and Blanka's tips, Dan is inspired by the success of the latter's "Blanka-chan" dolls and attempts to become popular by creating his own variation called "Saikyo-boy" dolls. His stance as a "weak" character is emphasized in the puzzle game
Super Puzzle Fighter II Turbo, in which Dan is a hidden character who drops only red counter gems, making him extremely easy to beat. In
Super Gem Fighter Mini Mix, Dan's story begins with himself looking to expand his Saikyo-ryu school and subsequently chooses Sakura as his student. Upon meeting Sakura, he offers to teach her his style and she accepts after Dan defeats her in a fight. Sakura masters the entire Saikyo-ryu style and chooses to forget the entire style three days after mastering it, humiliating Dan. Dan appears as a playable character in some Capcom crossover projects, including two crossovers with Marvel:
Marvel Super Heroes vs. Street Fighter and
Marvel vs. Capcom 2 as well as the crossovers with
SNK starting with
Capcom vs. SNK Pro. During the debut trailer for the crossover fighting game
Street Fighter X Tekken, Dan is beaten through a door following an encounter with
Tekken character
Kazuya Mishima. Even then, Dan does make a non-playable appearance as the "dummy" in the game's training mode. He is also seen in Sakura and Blanka's ending, trapped inside of Pandora. Dan makes a cameo in
Sentinel's
Marvel vs. Capcom 3 ending, being beaten and dragged by one of the giant robots. In
Street Fighter X Mega Man, Dan appears in between stages as Mega Man tests his new weapons on him. Dan is also shown to have a younger sister, Yuriko, who appears in his
Marvel Super Heroes vs. Street Fighter ending and as the in-game shopkeeper in
Street Fighter V.
In other media Additionally, Dan has had a small appearance in the
original video animation Street Fighter Alpha: The Animation. In the
manga Street Fighter: Sakura Ganbaru!, Dan is featured as a supporting character, where he is shown to be knowledgeable on how Ki is channeled through a person's body, acts as a guide for Sakura's first few fights and is competent enough to take on small-time fighters, but hopelessly outclassed with more skillful challengers such as
Balrog. Dan is also featured in
UDON's
Street Fighter series, where he views Sakura as a rival, though he is usually defeated without much effort on her part. A few issues have revealed that if angered enough he can tap into the Satsui no Hado, but still is not as intimidating as he trips over Sakura's backpack when he tries to use the Raging Demon. By the time of
Super Street Fighter: New Generation (which adapts the events of
Street Fighter III), Dan is shown to have lost his dojo and now works as a chef for
E. Honda. He assists Guile and Alex in rescuing Ryu and curing Sakura of the Satsui no Hado. In
Street Fighter Unlimited, Dan finally faces off against Sagat to avenge his father. Though Sagat dominates him throughout the fight, he gives up out of guilt and gives Dan the opportunity to finish him off, but Dan ultimately refuses to kill him as he realizes his father would not have wanted this. Dan' s name is mentioned in ''
Street Fighter: Assassin's Fist'' as a former student taught by Gouken before Ryu and Ken. In a deleted scene, Gouken tells Ryu and Ken how he taught Dan in his early days as a sensei but sent him due to wanting to use his training for revenge. Dan will appear in the
upcoming film, played by
Andrew Schulz. The casting of Schulz as Dan has been criticized as
whitewashing. ==Concept and creation==
