2. Annihilus
The Negative Zone has always been a huge part of the Fantastic Four’s world. This was especially true of its leader, the Cosmic Control Rod-wielding bug lord known as Annihilus.
He occasionally referred to himself as the living death that walks, although the phrasing feels at least a little bit redundant. In keeping with the redundancy theme, his other nickname was Annihilus the Annihilator. Annihilus the Lord of Redundancy was more like it.
Annihilus was the driving force behind Annihilation, a huge Marvel Cosmic event that spun out into books like Nova and Guardians of the Galaxy.
Annihilus and his invasion force, the Annihilation Wave, began pushing in an outward direction to conquer and destroy the universe. This plan did not end well for him, because Nova ripped him inside out. Which was, I’d assume, not a fun experience.
After Annihilus was reborn, he almost killed the Human Torch, and became a huge part of Infinity. He also fought the All New All Different Avengers in a pretty fun story arc.
