While this may seem like a blow out for Juggernaut don’t underestimate Firestorm. His power is amazing. He can create anything he wants. Remember he did beat Superman by trapping him in a kryptonite bubble. With Juggernaut he could just put him in a missile and launch it…never to be seen again. Sadly in the comics he never does things like that. Firestorm wins.

Now I’ve changed my mind. Firestorm has great powers but is lousy at using them. Juggarnaut wins.
