What, Jubilee Prime is God+2... What's so specious?(Superman, while angry, is God+1. Batman in his true form is GodxInfinity)
And I do believe Maelstrom can only stop select types of energy. Now Galactus, being Galactus, would probably have a way around something as small as losing all kinetic energy... Plus his "full power" puts him at the same level as Death and Eternity (I don't think it's possible for him to actually get there, but seeing as that's how he falls in terms of importance...)
