Despite the physical similarities, that's not Odin you see above, but a very ancient Thor who is the last surviving Asgardian on a dying Earth. His one arm - which the present day God of Thunder only recently lost - has been replaced by that of a Destroyer's, and he doesn't hesitate to still do his all to protect the world he loves. That included a mighty battle against Galactus, and despite literally being punched through the moon by the gigantic Fantastic Four foe, Thor took him down and managed to renew life on Earth. Whether he's young or old, Thor remains one of the toughest and greatest heroes of the Marvel Universe.
