For this one, I'll make an exception. I'll use the way Iron Man and Thor killed him in, I think it was the Sentry comic series. They stole the Helicarrier and crashed it into him, and the explosion was enough to turn him back into his normal human form, and then they killed him easily. That's probably the only way to kill him, too!
