onslaught is super powerful. It took the might of even the stongest of the strong (thor, hulk, jean grey etc..) plus some brave non-mutants to tek him down
war hulk only beat normal juggy. He would have gotten slaughtered if he fought 8th day juggernaut. You must not know how strong and unstoppable that version of juggernaut is. He manhandled thor, who couldn't even phase him. Thor had to use his hammer to suck up all the magic from around them and even then he still had a fight on his hands. No doubt that war hulk might become stronger than 8th day juggs, but more powerful is a whole other story. I say the fight lasts 5 mins then juggs rips the armor from hulk along with his limbs.
As for the fight with onslaught, 8th day juggs is more powerful than cyttarak(I know I spelled it wrong) and cyttarak is near as powerful as onslaught, which would give 8th day juggs a good shot at winning or at knocking him the flipp out. Oh, as for the people saying that superman could beat 8th day juggs. Answer this, if 8th day juggs is as powerful as pre-crisis superman, who is 1,000 more powerful than post crisis superman,then why the hell would you say that post crisis supes can whoop 8th day juggs. Must be if juggs had real bad writing. Other than that, supes gets trampled like a spectator at the running of the bulls. What are you people smoking.
