12 Comic Book Heroes More Powerful Than Superman
7. Doctor Strange
He might not have started his appearances in the MCU particularly powerfully, but back in the golden days of the comics, Doctor Strange was a supremely formidable character and a hugely powerful one at that. He might not have the superhuman capabilities of Superman - in that he can't match him for speed, power, strength or anything else quite so blunt - but he's a far more elegantly gifted figure.
Most crucially, he's the most accomplished magical character in all of Marvel's gallery, able to cast forcefields that would repel Superman without much effort. His command of the Crimson Bands - a favourite spell and a famous one - means he's capable of easily restraining beings as strong as Hulk. and that's without even considering the offensive spells that would incapacitate him or worse, which he'd have little chance of defending himself against.
And if my praise of him isn't sufficient, he was also called "the mightiest magician in the cosmos" and "more powerful by far than any of your fellow humanoids" by Eternity, Marvel's omnipotent version of God, basically.
