Kingdom Hearts: Superhero Keyblade Taisen

Superhero Keyblade Taisen, AKA Superhero Keyblade Wars, is (currently) a fan project taking place after the upcoming Kingdom Hearts 3. It is the first title in the Kingdom Hearts series not to feature Disney characters, but instead have characters from other Disney-owned properties such as the Marvel Superheroes, and also characters from Capcom and Toei properties, including Street Fighter, Megaman, Super Sentai/ Power Rangers, and Kamen Rider. It was conceptualized as an action/RPG like the other games in the series, but the creator is currently entertaining the idea of turning it into a web-series, similar to Alvin-Earthworm's Super Mario Bros. Z.
