The Mighty Thor (Vs.) Swamp Thing
Could Thor stop Swamp Thing? Could Thor, being the son of an Earth goddess, stop someone as powerful as Swamp Thing, who himself is an Earth elemental?
Let's say that Thor, instead of rebuilding Asgard above a Nebraska cornfield like in his current series, he decides to rebuild Asgard smack dab in the middle of a Louisiana swamp, above where the Parliament of Trees already is.
Well, this doesn't sit well with Swampy and he tells Thor he needs to move Asgard somewhere else. Thor then tells Swamp Thing to pretty much go **** himself, he'll do whatever the hell he wants to do.
And so thus begins the battle of the children of Earth, with The Mighty Thor battling The Swamp Thing.........
