Deadpool famously has one of the most powerful healing factors in the Marvel Universe, as there aren’t many people who can be decapitated or totally obliterated and get back up (not even the likes of Wolverine and the rest of his ‘Snikt’ Family). However, during one particular storyline, Deadpool utterly outdoes even himself by proving he’s immune to Marvel’s most powerful god.

In Deadpool Team-Up #899 by Fred Van Lente and Dalibor Talajic, Deadpool has teamed up with Hercules, and the two are trapped in a labyrinth built by Arcade. However, the labyrinth is secretly being powered by the otherworldly magic of a being who has proven himself to be even more powerful than Marvel’s strongest gods: Nightmare.

Hercules offended Nightmare during one of their previous encounters, so he sought to make him pay – and Deadpool was just along for the ride. While Nightmare saw Deadpool as nothing more than an additional inconvenience in his plan to torment Hercules, he soon learned that Wade was far more than that. When Deadpool realized Nightmare’s powers were controlling the hellish maze, he severed his own corpus callosum, meaning Nightmare’s dream-based powers had no effect on the Merc with a Mouth, leading to Nightmare’s ultimate defeat.

Why Deadpool Defeating Nightmare is His Most God-Tier Trick Yet

Marvel #4 “Overture” by Alex Ross, Steve Darnall, and Kurt Busiek

While Deadpool’s trick against Nightmare may seem like a run-of-the-mill Deadpool gag, it’s actually one of the most god-tier feats he’s ever pulled off, and Nightmare’s storyline in “Overture” proves it. In “Overture”, Nightmare decides to try to take over the entire Marvel Universe. In that effort, Nightmare kills Galactus, an army of Celestials, and even Ego the Living Planet before confidently challenging the likes of Eternity and the Living Tribunal.

Nightmare channeled his power from the Dream Dimension – within which he is a true god – to use it against Marvel’s strongest entities, and effectively came out on top. And that’s why the fact that Deadpool defeated Nightmare by severing the connection between the left and right sides of his brain (which made Nightmare’s dream-based powers ineffective) is so incredibly impressive – perhaps, even, the most impressive victory Deadpool has ever won.

Deadpool’s Victory Over Nightmare Proves He Actually COULD Kill the Marvel Universe

The Deadpool Kills the Marvel Universe books are way over exaggerated, especially in regard to Deadpool’s power level. Sure, most of the heroes and villains Deadpool kills would actually lose in a fight to the death against Wade, but the idea that he could kill the Marvel Universe (Abstract Entities and all) is laughable. Except, that’s not true anymore.

Deadpool can defeat Nightmare, and Nightmare can defeat the strongest beings in the universe. That means, if Deadpool really did decide to kill the Marvel Universe, he’d have to find a way to get Nightmare to launch an attack like he did in “Overture”, wait until he’s victorious, and then use this trick to beat him. At that point, Deadpool would actually be successful in killing the Marvel Universe – no meta over exaggeration required.

While the implications of Deadpool’s victory over Nightmare are fascinating, and a lot of fun to consider, the biggest takeaway isn’t what Deadpool could do with this trick, but what he’s already done. By utilizing his healing factor (in a decidedly R-rated way), Deadpool made himself immune to Marvel’s most powerful god.
