10 Most Powerful Characters Killed By Iron Man
1. Galactus - Marvel Zombies Dead Days
A primordial cosmic entity, Galactus is easily one of the Marvel universe's most powerful beings and can easily mow his way through multiple teams of powerhouse heroes. This is unsurprising since the being formerly known as Galan of Taa wields the Power Cosmic and is fueled by consuming whole worlds.
That said, the Devourer of Worlds is not all-powerful, as evidenced by the gory thrills of the Marvel Zombies series. After his herald the Silver Surfer was eaten by the zombified heroes of Earth, Galactus makes his way to the planet to confront the heroes, which included the likes of Iron Man, Hulk, Spider-Man and Luke Cage.
Initially, he fared off fairly well against the undead humans, despite them being powered by his former herald's cosmic energies. This advantage was however short-lived as the zombies devised a weapon to weaken the extraterrestial being and then feed off him, gaining even more power in the process.
