Everything in history predating the re-creation of the Multiverse has gone malleable. Thanks mostly to Mr. Mind and that Kryptonian boy's tantrums, which I still find ridiculous to believe. Punching history. Please.
I'm a scientist, really. I prefer thinking, strategy, and proving hypothesis to physical altercations or fisticuffs. But that's not to say that I'm inexperienced in them. In fact, I've studied and mastered the martial arts and fighting techniques of cultures and societies from B.C. to the end of time. You say you're doing what should be done? I say something else entirely. Simply put, Junior... your ass is mine.
