Galactus as written by people who are determined to make it really obvious that the heroes fighting him are powerful and who want to make a lazy Galactus loses story, will lose to godforce, Superteam and Wolverine. Galactus written as he was first described, is generally described and as befits his status, the one who crushed the skrull homeworld and can consume multiverses, wins easily.
You know, I really like Galactus but this is getting ridiculous. These Galactus threads are getting like Wolverine was a couple months ago. If you want Galactus to lose then you need to put him up against an uber Cosmic, not some version or versions of Superman who will never stand a chance against G.
Big G has jobbed once or twice. But given his power level and versatility, there's no way he should lose.
He's a better telepath than Xavier (yes, he is...read Secret Wars). He can create people on a whim that could beat your average herald-level person. He Eats Planets. Planets. Even ridiculous numbers can't compete against someone like him. Would you be scared of 100 ants? 500?? Even if they had prep? Didn't think so. Annoyed maybe, but not scared for you life.
