Mechanics
The game features battles of teams of heroes and villains, with up to three characters in each team. Characters can be tagged out at any time.

Saitama
Just like in the anime and manga, Saitama can instantly KO any opponent with just one punch, and in invulnerable to any attack. As this would make for a one-sided fighting game, matches with Saitama employ a special timer.

If Saitama is selected for a player's team, he will not immediately be playable. Instead, a timer will appear at the side of the screen, showing Saitama running to the scene of the fight. If the player can keep their remaining two fighters alive until the timer runs out, Saitama will appear and can be used to win the battle. (Unless the opponent also has Saitama on their team, in which case the two can only punch each other ineffectively until the timer runs out) Performing combos and perfect counters will shorten the timer.

Alternatively, players can also select Dream Saitama, a pyjama-clad version of Saitama based on the dream he has at the beginning of the anime. In this form, Saitama has all of his usual attacks, but cannot KO opponents with one hit, allowing him to be used in more fair battles.
