To expand on my earlier post, this is how it could go down (if that idiot Loeb is writing) Juggy and Rulk run into each other in L.A. Rulk says "Well well, Juggernaut, my mutant friend, you're next on my list"
The two charge into each other, and as he would expect, Cain starts to push Rulk back. Rulk, with a wry smile on his face utters a mysterious phrase "Cyttorakus neutralisus" With that, the tide turns, and Rulk starts pushing Juggy back. He then proceeds to rip Cain's helmet off, and punches him in the face, repeatedly, making a real bloody mess of it. "h..how?" asks Cain "Simple" replies Rulk "my little spell neutralised your enchantments for unstoppability and total invulnerability. Your strength is as great as ever, but you can now be stopped or hurt by sufficient physical force- and baby, I got that in spades"
Rulk then laughs and continues with his brutal two fisted assualt. He is just about to administer the final, killing blow when there is a loud 'THOOM' and turns to see Galactus behind him, with the Silver Surfer at his side. "Cease your rampage fake Hulk" demands the Surfer "or we will finish it for you" utters Galactus.
Rulk just smiles, and nonchalontly kicking Juggernauts prostrate body away, says "So now I get to add the Silver Surfer and the vaunted Devourer of Worlds to my growing list of smashed opponents"
The issue ends with Galactus firing his destructive eye beams at Rulk who easily blocks them with his hands and then deflects them back at their source, toppling Galactus. A clearly fearful Surfer prepares to launch his own attack, saying to himself "This is a truly unbeatable opponent, against whome, I cannot prevail-but for the sake of the multiverse, I must try"
And you can imagine how the next issue goes-Rulk wins again
