seriously? 10x?? anyone who looked at that first fight and thought--damn, g was MORE than 10x as powerful as odin must be del-f******-irious. g had more reserves, but was still flash ko'd by odin in that fighgt. christ, it's almost like people quite literally don't know how to read. an 'average' galactus is not exactly impressive in a lot of instances btw. hell, give THOR 10x his usual power and he'd give avg galactus a tough time. 10x odin? c'mon.
Galactus smites the impertinent one-eyed fool.
Galactus could simply consume EVERYTHING that empowers Odin, and Odin wouldn't have a thing to say about it.
Just because Marvel makes him job out to make one-eye look less ... irrelevant, doesn't mean we ignore the monstrous gulf in power between these two.
Galactus destroyed a third of the Annihilation wave, whilst weak and almost drained, vapourised a Watcher and many solar systems...
The only reason Galactus "runs away" is because PIS requires a way for Thor to survive and Galactus, like Surfer, has no real stake in anything so he never really cares to fight.
In a forum battle, he would be angry and intent on causing damage, which would mean that Odin would die painfully.
