Tekken X Street Fighter was a planned crossover fighting game that was being developed by Bandai Namco Entertainment. It was supposed to cross the universes of Namco's Tekken and Capcom's Street Fighter into one game, creating a roster from both franchises. The game was announced at the 2010 San Diego Comic-Con International by Bandai Namco producer Katsuhiro Harada. The gameplay of Tekken X Street Fighter was going to feature the same 3D fighting game engine of the Tekken franchise, as opposed to Street Fighter X Tekken, which features the 2D-style gameplay of Street Fighter IV. Bandai Namco put the game's development on hold in 2016.

Jin Kazama is a character of the Tekken fighting game series created by Bandai Namco Entertainment. Introduced as the protagonist in the 1997 game Tekken 3, he has been the central character of the series from that game onwards. Trained by his grandfather Heihachi Mishima, Jin wishes to avenge the apparent death of his mother Jun Kazama by Ogre.
