* OneHitKO: Unless it's a MirrorMatch against another Saitama, Saitama knocks out any opponent with a single punch.

* TakesOneToKillOne: According to this game, the only character that can defeat Saitama is another Saitama.[[PlayingWithATrope Of course since other characters can chip Saitama's lifebar no matter how small, then if you're that much of a]] GodlikeGamer [[PlayingWithATrope you ''could'' defeat Saitama without the use of another one]]; [[ScratchDamage but since Saitama has so much health]], is ImmuneToFlinching, [[LightningBruiser has the highest speed in the game along with Sonic and can kill you with only a single melee attack]], along with every one of those moves [[Unblockable Attack being completely unblockable]], then being able to do so is incredibly unlikely.]] Not that it hasn't been done against a CPU Saitama before as seen [[https://www.youtube.com/watch?v=TjLIxZySLq4 here]].
* UnblockableAttack: Metal Bat and Child Emperor's Super Killer Moves can pierce though the opponent's block it's nothing to fully deliver their strongest attacks. But the already overpowered Normal Saitama ups the ante by having ''every'' attack he has be unblockable attack. If you're doing the Rematch mission against Saitama where you have to reduce 10% of his lifebar with your custom character in 180 seconds (thankfully the timer stops temproarily when Super Killer Move animations are playing), then using Metal Bat's Ultimate when selecting Weapon Type A or B as your character's moveset is a big neccesity to clear the mission as seen [[https://www.youtube.com/watch?v=1liY3-gkgYs&t=394s here]].

* HopelessBossFight: Fittingly the final boss battle in story mode is against Saitama himself. Naturally, you're not gonna win this because Saitama's health bar barely even chips. Eventually he finishes it with a punch that thankfully doesn't destroy the player character but does knock them on their back.

* UnstoppableForceMeetsImmovableObject: It's possible to get a fight between two Saitamas. If this happens, they're technically able to damage each other, but remain ImmuneToFlinching, and if one's life meter is reduced to zero they suddenly realize that [[SkewedPriorities Bargain Day at the local supermarket is almost over]] and take their leave.

* BigDamnHeroes: Enforced with Saitama: he can't be used at the beginning of the fight, and is meant to arrive when the player is struggling to hold out against an opponent.

* AdaptationalJerkass: In the source material, Genos is nice enough to others despite being TheComicallySerious. Here, his desire to become Saitama's disciple clashes with the custom protagonist's own, resulting in him becoming very short with the protagonist and even threatening them with violence (and being [[IllKillYou "erased"]]) ''despite knowing they're a fellow hero''. Though he mellows out pretty much instantly when [[spoiler:Saitama assigns the protagonist to be ''Genos's'' disciple]], implying this is mostly from his desire and desperation to learn from Saitama.

%%* DifficultButAwesome: Saitama is built to be this. Choosing him forces you into a 2-on-3 fight (unless the other player chooses Saitama as well), but if you're able to HoldTheLine and run down Saitama's timer, you win.
