I don't want to sound naieve (hope I spelled that right) but who is a bigger authority on Marvel characters then the Marvel writers?
Was it not Greg Pak who said Juggernaught was the strongest?
I believe that is who said it, if I am wrong please correct me.
I stated earlier that Sentry at his full power during WWH was beaten by Hulk, the same Hulk who was barely holdling his own against Juggernaught just a day or two earlier.
Many have debated the fight at the Xmansion between those two but if you closely look Xavier distracts Juggs, and Hulk trips him, it can be said that Hulk knew he could not beat Juggs and used a cheap shot to delay Juggs.
Just my spin on it
