Galactus invades the dimensions of the Hell Lords
We saw how things turned out when big G took on Mephisto for the life of the Silver Surfer. As a side comparison we've also seen the Stranger take on Pluto in Hades.
So how would Galactus fare if he had to invade the dimensions of other Hell/Demon Lords? Could he defeat them even by trying to consume their dimensions and could they stop him? Where is Galactus victorious and from which dimensions does he not return?
1) Dormammu in the Dark Dimension
2) Surtur in Muspelheim
3) Ymir in Niffelheim
4) Magik in Limbo
5) Pluto in Hades
6) Hela in Hel
7) Blackheart in the Darkforce Dimension
8) Nightmare in the Nightmare Realm
9) Lucifer in Hell
10) Cyttorak in the Crimson Cosmos
Remember, this is not a gauntlet - each fight is separate and Galactus is at his average classic levels having recently fed.
