The Street Fighter franchise is about to get a major boost with the potential addition of four new characters in Season 4 of Street Fighter 6. The leak, sourced from a credible Reddit user RnK_Clan, suggests a crossover with Final Fantasy, specifically featuring Tifa Lockhart, a fan-favorite character. This would be a significant development, as Tifa would be the first non-fighting game crossover character in Street Fighter, not from Final Fight. The inclusion of Tifa in Street Fighter 6 has been a long-standing request from Tekken fans, who have been hoping for her inclusion in their 3D fighter for years. The leak also includes Vega, Gouken, and Mike Haggar, adding to the excitement. The addition of Tifa would mark her return to an official fighting game for the first time in almost three decades, since Ehrgeiz: God Bless the Ring in 1998. This potential crossover with Final Fantasy is a significant development, as Square Enix has been open to giving out their big characters to other fighting games. The leak's credibility is a concern, as the original post was deleted, but the source's track record is generally reliable. With Ingrid set to release later this Spring, the official announcement of Street Fighter 6 Season 4 is expected in June or July, providing further clarity on the leak's validity.
