Despite a somewhat mixed commercial debut due to bugs (especially on PC), Marvel Tōkon: Fighting Souls is already gearing up to introduce new content.

On ResetEra, user Neoxon has datamined elements that reveal upcoming additions. For example, a screenshot shows the phrase: "Kamala is thrilled to see Groot and Rocket (but watch out for his appearance, as this is an upcoming DLC)." Thus, it seems Rocket Raccoon from Guardians of the Galaxy is expected to join the ranks as a playable character.

In addition, Legacy and Classic costume variants for Hulk, Spider-Man, the Green Goblin, and Doctor Doom have been spotted. Finally, a Battle Pass will be available, offering various rewards.
