Hmmm, as to getting something more powerful than swords. Its not like two pieces of metal with grips. (I'm sure seriananth will understand this) but, They are my friends, I have fought countless foes. They have saved my life many times. I've grown quite comfortable with them. They are part of me, ya know? To replace them, would be like saying to your right hand. "Time to go, You need replacing" Its wouldn't be right. I dunno maybe I'm rambling.

As to limited powers. I like a challenge. And as they say, absolute power corrupts absolutely. Sure, I could cause each atom inside the hulks body to split and have him evaporate into billions of seperate particles. but wheres the fun in that?
