I am on my phone so no link but have you looked up any of the avengers threads?
This is something that's pretty hard to do without house-ruling things pretty substantially. Quite frankly, Pathfinder isn't very good for it. If other game systems are an option, try Aberrant. It's exactly what you are looking for - super-hero powers with things that are close enough to magic/psychic abilities that you can pretend to be The Hulk, Magneto, Superman - whomever.
If you are set on Pathfinder, consider granting effects like Bull's Strength, Expeditious Retreat, Cat's Grace and the like as permanent effects, and giving them spells like Telekinesis as spell-like abilities. Let them really get those stat scores up there. Possibly a 40 or 50 point buy.
There are plenty of good super hero based rpg games out there. Take a look at Mutants and Masterminds or Palladium Heroes Unlimited. I think I remember seeing a Marvel rpg at a book store once. No real reason to recreate the wheel when someone else has already done the work.
Ah, I was imagining you creating a marvel campaign from Pathfinder, which would be quite difficult. If anything comes to me, I'll let you know.
