In order to defeat a character your powers have to give you an advantage. The Rhino is stronger than Spiderman, but Spiderman's superior agility, Spider sense, reflexes, and webbing allow Spiderman to constantly kick the crap out of the Rhino. The sum total of Spiderman's powers trumps the sh!t out of Rhino’s strength. That being said...
Wolverine simply isn't bringing enough to the field of battle to fight some one with Class 100 strength, flight faster then speed of sound, a body that can not only effortlessly withstand the pressure of the ocean, but thrive in it, last for short periods of time unaided in the vacuum of space, reflexes so fast that he has effortlessly dodged bullets and lasers, and has went toe to toe with the most powerful heroes and villains in the MU.
Oh yeah that's right.....Wolverine has a healing factor.
OK so when they fight wolverine can scratch at him with his Martial arts techniques and Namor can grab him (with the same reflexes that can effortlessly dodge gun and laser fire) and chuck him into outer space and let him "heal" from that. Or hold his little peak human ass or hell give him the strength of Spiderman (10 tons) because he still won't be able to break Namor's grip that could crush a wrecking ball and fling his little 5' 3" ass into a volcano and let him "heal" over and over again until the fricken Beyonder feels sorry for his ass.
Why the hell is this fight lasting 16+ pages again?
