Full Powered Galactus...
They have to kill him. Remember the Avengers have a month of prep. The Gauntlet combatants have none. For the last battle(if they make it), All members allied with the Avengers have a month of prep. Galactus doesn't. No Ultimate Nullifier, No IG, No Cosmic Cubes, NO HOTU.
They easily get past 6. King Thor alone could probly take out a 25% Galactus and then everyone else gangs up on Stardust.
They'd probly get past 7 too. Sersi can keep Strange occupied. King Thor & Quasar could take out Dormammu. Binary & Everyone else can take out Shuma Gorath, then everyone comes to the aid of Sersi and now it's everyone against Strange.
They easily beat a full powered Galactus. In my opinion Full Power Big G is equal to 3 high-level Skyfathers. King Thor is one, Binary is close to one, Genis is close to if not one, Thanos is close to one, Champ w/ Power Gem is close to one, plus there's other extremely powerful guys like SS, Quasar, Mar-Vell, Sersi, Strange, Magus, Warlock, and then add the distractions and physical damage from the powerhouses like Savage Hulk, Immortal Hercules, Namor, Wonder Man, and Gilgamesh! I think Big G's screwed.
Plus with Tony Stark there and gettin a month of prep, Big G or anyone else for that matter has no chance.
