In an earlier version of Avengers: Infinity War , Thor, Rocket, and Groot were going to travel to Jormungard, the home of the World Serpent in order to retrieve Thanos-killing weapon, Stormbreaker.That monster first appeared in 1952's Marvel Tales #105 and according to Senior Visual Development Artist Rodney Fuentebella, the axe/hammer would have been buried in the head of the monster but after the God of Thunder retrieved it, he and the Guardians would have had to battle the World Serpent's children in what sounds like it would have been an insanely cool action sequence!Now, some concept art shows both those monsters and the trio's journey to the mythical realm.As if that's not enough for you, we also have some pieces from Avengers: Endgame revealing that Thor was originally going to come face to face with his ex-girlfriend Jane Foster in 2013-era Asgard.To check out this new concept art, all you have to do is click on the "View List" button below!
