3 Justice League Heroes Who Can Beat Saitama — and 3 He One-Punches

Ready for the ultimate power-scale meltdown? It’s Justice League vs Saitama, the Caped Baldy who ends battles before they begin. Can DC’s mightiest survive his first punch, or is this the quickest crossover clash ever?

Alright, let’s stir the nerd pot: Justice League vs Saitama from One Punch Man — the guy whose whole brand is ending battles before they even start. On paper, that’s a mismatch. In practice? Depends on what kind of comic-book nonsense you’re willing to allow.

Why Saitama is the end credits

Here’s the deal with Saitama. He’s not just strong — he’s parody-level strong. We’re talking jump-from-the-moon-and-stick-the-landing strong. We’re talking one punch that can erase a city strong. He’s designed to be the final boss who got bored and went grocery shopping.

If you can mess with time, the mind, or reality itself, you might actually have a shot. Otherwise, good luck touching him before the fight is already over.

The matchups that actually matter

Some Justice Leaguers have the kind of game-breaking abilities that could tilt this into an actual fight. Others... would not last long. Here’s the whole thing in one go:

• The Flash (Wally West): Not just a fast guy in red. Wally has outrun death, bent timelines, and pulled Speed Force tricks that spit in the face of physics. Against Saitama, speed is the one real counter: he can dodge the punch, time-dilate the battlefield, or drag Saitama into a Speed Force trap. Outcome: could win.
• Superman: The poster child for overpowered. Clark has shoved planets, tanked supernovas, and gone toe-to-toe with literal gods. This one turns into a shonen brawl where continents cry. It’s less instant KO and more who blinks first while the universe files an insurance claim. Outcome: 50/50 slugfest.
• Martian Manhunter: J’onn isn’t just ‘green Superman.’ He’s a telepathic nightmare who can phase through attacks, read and disrupt your thoughts, and go intangible so punches do exactly nothing. He could turn to mist while Saitama winds up, or just flick the brain’s off switch. Outcome: very likely to win.
• Batman: Love the guy. But at the end of the day he’s a peak human in a very expensive suit. Even with prep, there’s not a gadget that meaningfully answers ‘fight ends in one punch.’ Take away prep and it’s Gotham to stratosphere in seconds. Outcome: one punch and out.
• Green Arrow: Oliver’s trick arrows and elite aim are great against, say, anyone who isn’t a bald hurricane. Against someone who shrugs off meteor-level threats, arrows are props. Outcome: KO before the shot lands.
• Nightwing, Black Canary, The Question, other street-level heroes: Love them, watch them every time — but this is like trying to spar with a natural disaster. Even the best dodges and combos don’t matter when the other guy’s whole move-set is ‘instant delete.’ Outcome: roadkill in under a minute.

The inside baseball

Saitama’s core bit is narrative overkill — he exists to end fights. That’s why your only real counters are cheats like time control, telepathy, phasing, or reality hacking. The Justice Leaguers who live in that lane make it interesting. Everyone else? Fun to imagine, not fun for them.

So who actually wins?

If you’re betting: Wally and J’onn have the best tools to break the bit. Superman makes it an instant classic coin flip. Batman, Green Arrow, and the rest of the street-level crowd? Brave, doomed, and airborne.

One Punch Man is streaming on Hulu if you want to revisit why this debate is chaos in the first place.
