7 Best Upgraded Versions of Marvel Heroes, Ranked

by

Marvel Comics has some very powerful heroes, but when you usually think of superlatively powerful superheroes, you think of their distinguished competition (unless you’re an MCU fan; then you think Marvel has the most powerful heroes, which isn’t correct). Sure, there are exceptions to this rule and most who have read Marvel can name numerous heroes who do have phenomenally high power levels, but for the most part, the House of Ideas’ main heroes are on the weaker end when you compare them to heroes at the same level at DC. However, that doesn’t mean their power levels are set in stone; over the years, many heroes have gotten major power upgrades, sometimes temporarily and other times as a permanent buff.

Over the years, many Marvel heroes have received power boosts, with varying degrees of impact. Some were minor, but others dramatically increased their abilities, becoming iconic moments in their stories. Here are seven of the most impressive power-ups that made these heroes even stronger.

7) Immortal Hulk

The Hulk and power-scaling go hand in hand, to the extent that any time you talk about the Jade Giant online, you get inundated with power scalers talking about “feats” and never stories. In a lot of ways, the most beloved Hulk run of recent years made it worse. The Immortal Hulk is outstanding and it changed everything about the character. First off, obviously, it made him an immortal, and then it changed the nature of powers, revealing that he is an avatar of the One Below All and the living embodiment of entropy. It took an already powerful character and made him more so. Sure, it’s partly ruined online Hulk discourse but it’s given us great stories at least.

6) Phoenix

Jean Grey is considered the most powerful member of the X-Men due to her connection with the Phoenix Force. She was already a remarkably strong telepath and telekinetic mutant, but the Phoenix Force dramatically amplified her abilities. It boosted her mental powers to an incredible degree and granted her immense cosmic power, essentially allowing her to do anything. Though recent portrayals of her as a force of death and rebirth haven’t been universally praised, fans remain captivated by Jean as the Phoenix, and it’s likely to remain a key aspect of her character for years to come.

5) Binary

Rogue drained Carol Danvers’ power in Avengers Annual #10, and she ended up hanging out with the X-Men for a while. Eventually, she’d end up developing powerful energy manipulating abilities and become Binary, joining the Starjammers. She was able to channel massive amounts of energy – she created a white hole to save the Sun in Quasar #34 during “Operation Galactic Storm” – and was at her most powerful during this period. She’d lose her Binary powers and get her old ones back, but they’ve showed up again numerous times, making her more powerful than ever.

4) Omega-Level Iceman

Omega-level mutants are the most powerful in X-Men history. Some Omegas are pretty surprising but the one that shocked readers the most was Iceman. Bobby Drake’s powers had been getting better for years – he had to wear an inhibitor belt for a time after a battle with Loki and Emma Frost was trapped in his mind showing him how to use his powers better in the early ’90s – but his Omega buff took it to another level. He can create an army of ice constructs that can move on their own and has been able to freeze the flames of Hell. He’s reached a rather ridiculous level of power and has become one of the most potent X-Men.

3) Godkiller Iron Man

Iron Man is famous for constantly improving his suits of armor, making them more and more powerful. He’s been designing specialized suits for years – the Hulkbuster is a prime example, becoming iconic thanks to the Marvel movies (though the comic book version wasn’t much more than a pile of spare parts!). He’s built armor to battle incredibly powerful beings like the Phoenix Force and those with cosmic abilities, among many others. But his most impressive creation is the Godkiller armor, which transforms him into a giant, kaiju-sized hero capable of fighting Celestials. Tony Stark only uses this ultimate suit when facing the biggest, most dangerous threats, and it’s easily one of his most visually striking designs.

2) Cosmic King Thor

There have been numerous power upgrades for Thor, with Warrior Madness Thor (his power was tripled and he got the Power Gem) and Rune King Thor previously being the most powerful. However, all of that would change in 2020 when readers were introduced to Cosmic King Thor. He was King of Asgard at this point, tapped into the power of the Odinforce fully, and fooled Galactus into making him a Herald, adding the Power Cosmic to the mix. Then he killed the World-Devourer. It’s rare for anyone under a legitimate capital G God to be able to even defeat him, let alone kill him, proving that the Cosmic King Thor is easily the most powerful version.

1) Cosmic Spider-Man

I’ve always loved Spider-Man because he feels so human, even with powers! It’s funny, he’s super strong – like, able to lift ten tons – but compared to other heroes in the comics, that’s actually not that strong. He usually wins fights because he’s quick, his spider-sense is amazing, and he just never gives up. But there was this one time he got even more powerful! He merged with this cosmic energy called the Enigma Force and became Captain Universe – most of us just call him Cosmic Spider-Man. He got a huge boost in strength, gained these incredible energy powers, and could even control matter with his mind! It let him take down some seriously powerful villains, and it was awesome to see.
