Solomon Grundy vs. The Incredible Hulk
I almost thought that Bane would be a better fit here, but seriously if you are going to pit two total brutes against each other, let’s grab the two that are nigh indestructible. That way the battle won’t have an obvious handicap. One is a gamma radiation-fueled beast of immeasurable rage. The other is the undead spawn of evil who never seems to be truly dead, no matter how many times he is killed. Both have super-strength and seem to be able to fight on for days without tiring. These things alone make this a match of monumental proportions and one that I look forward to.
