Battle is on Earth(and entire Solar System)
Round One:Odin ,Zeus and Amateratsu all at full power vs Standard Galactus-No help from Thor,Hercules,Avengers and No Heralds
Round Two:Odin with Destroyer Armor,Zeus and Amateratsu, if they are about to lose then the rest of Earth's Skyfathers appear to help(Hindu,Egyptian and any other) vs Standard Galactus
Round Three:Same as above but Odin empowers the destroyer with every Asgardian soul,gets the Odinsword and Thor,BRB,Hercules and Silver Surfer(on earth's side) intervene.Just Zeus and Amateratsu this time.
Can Earth's skyfathers protect the planet?
