10 Characters Who Have Defeated Galactus
8. Thanos
The Mad Titan and the World Eater have crossed paths quite a few times within the pages of Marvel Comics. The one showdown to remember is the fight that went down during the epic Infinity Gauntlet storyline.
Thanos gets all the Infinity Gems becoming the most powerful being in the universe. This catches the Great Destroyer's radar and he can't have any entity in the galaxy be bigger and worse than him.
Things got more heated when Thanos interrupted Galactus' dinner by destroying a planet with his new-found powers Big G was hoping to munch on. This caused a big blow to the cosmic baddy's pride and would have him do something he never dreamed of doing in order to stop the newly crowned purple planet destroyer - he would have to partner up with mortals.
Earth-616's finest and Adam Warlock fight alongside the Devourer of Worlds, and they are quickly decimated by the Mad Titan very easily. Thanos does eventually get taken down after things don't exactly go as planned, but the thing to remember is that it happens after Galactus gets swatted like a fly. This kind of beatdown stays with a person long after and stings every time.
