AAP said:I mean in terms of brute strength. Not any fancy pants powers.
I always thought the Hulk was. However, I have a comic where a dude named Hyperion knocked Wonder Man all the way through an entire planet into the sun.
^^^In pure form, The Hulk and The Thing are neck in neck for strongest superhero.
However, The Beyonder can change form in to anything he wants including another Hulk or Thing, so he technically is the strongest in the marvel universe.
The Beyonder is the guy who fucks with the superheroes for shits 'n' giggles.
