Saitama
Saitama is not a playable character from the roster, due to his ability to OHKO opponents with one strike. Spike Chunsoft instead integrated him not as a playable character but as a representative of time.

From gameplay trailers, Saitama is revealed to be a timer, taking around 120 seconds to reach the fight. If a character can stall the fight long enough, they will be rewarded with Saitama's one hit knock out.

The timer can be shortened by performing perfect guards.
