Dataminers say they have found references to five possible future characters in Marvel Tokon: Fighting Souls: Doctor Strange, Wasp, Gambit, The Thing and Daredevil. The discovery has prompted speculation about the game’s DLC plans, although there is no confirmation that any of them will become playable and the listed assets may change.

Arc System Works reportedly made it difficult to extract unreleased content from the game’s files, with another dataminer finding mainly battle-pass assets. The game’s next confirmed addition is Phoenix Cyclops, due in autumn 2026; he will lead a team whose remaining members have not yet been announced.
