Ego the Living Planet
First seen Thor #132 (Sep 1966)
It seems ridiculous to call an entire planet a supervillain – but not to Jack Kirby, who was tossing out bizarre lost worlds and incredible cosmic villains every issue in mid-’60s Thor and Fantastic Four. Ego was a nefarious sentient world of near limitless power and malevolence who lurked within the Black Galaxy. When Thor first met him he introduced himself as “the largest, most powerful intelligence in all of infinity! You are like dust unto my feet!” (We suspect he meant “under”, but who are we to argue with someone who possesses “powers without end”?) Along with Galactus, the Silver Surfer, the Kree and the Colonizers of Rigel, Ego’s one of the building blocks of Marvel’s space mythology.
