After 88 Years, DC Finally Reveals Superman’s True Power Limit

In his 88 years of comics, Superman has pulled off countless incredible feats, yet his strict moral code has always forced him to hold back, keeping the true extent of his powers hidden. Now, DC has finally put the Man of Steel in a situation where there are no limits, giving fans their first true look at just how far his power can go.

DC’s latest crisis event continues in DC K.O. #4 by Scott Snyder, Joshua Williamson, Xermánico, and Javier Fernández, where Earth’s heroes and villains are forced into tournament-style deathmatches to collect Omega Energy and crown a single champion powerful enough to take on Omega King Darkseid.

This issue raises the stakes by introducing Darkseid-controlled versions of Absolute Wonder Woman, Batman, and Superman into the battle. The clash culminates in a brutal one-on-one confrontation between Earth-Prime Clark and Absolute Clark, revealing the full extent of Superman’s power.

Even though the DC K.O. event has technically given Superman the moral freedom to unleash his powers to their full extent, the Man of Steel has consistently held back when facing his friends and foes. Until now. DC K.O. #4 pits Superman against Superman, giving Clark the final push he needs to truly unleash himself.

Facing off against a Darkseid-imbued Superman, Clark is forced to tap the full extent of his powers as the two clash. The battle reveals some absolutely insane power metrics, including that when the two Supermen collide, they unleash 52 megatons of energy, the approximate yield of the Tsar Bomba, the largest nuclear weapon ever detonated.

This is a blast with world-altering destructive potential, and if Clark hadn’t reabsorbed the energy, it could have obliterated his allies. It’s rare for DC to give exact numbers for Superman’s powers, making this a notable moment in the Man of Steel’s comic history. And this wasn’t the only staggering power metric revealed in the issue.

Earth-Prime Superman soon begins to feel the toll of the fight, his body tiring against the “younger, scrappier,” Darkseid-empowered, Absolute version of himself. In a moment of desperation, he amps up his heat vision to “a million bursts per second,” another insane metric. Yet even this is not enough to overcome Absolute Superman.

Superman then turns his attention to the Darkseid-possessed Booster Gold, targeting the source of the malevolent power. The narration reads: “Clark gives it everything. Every ounce of energy, physical, mental, spiritual. It’s a punch that could break the world. Even a god’s concentration. Even for a moment.”

This punch serves as the cherry on top of the incredible feats Superman achieves in DC K.O., offering perhaps the most definitive depiction of the Man of Steel’s true limits to date. To find out how this Superman vs. Superman battle ends, you’ll need to check out the full issue.
