Galactus wants to eat Earth but is well aware that he is not powerful enough to do it. Therefore, he recruits some new power heralds to assist him with his quest. He gets the following characters:
All of them have sacrificed their willpower to Galactus in exchange for power enhancements (each character has doubled in their intelligence, durability and power) the opportunity to take his place when he dies. They preplanned their assault by assassinating Illumanti (so no infinity gems) and destroyed the ultimate nullifier but they did not plan on cosmic or otherworldly hero being able to assist (ie Silver Surfer, Thor).
Under what scenario and/or what Marvel heroes can defeat Galactus and his super powered heralds?
