Ego the Living Planet

Few cosmic concepts in comics history hit as hard as a literal living planet, and Ego the Living Planet has been unsettling the Marvel Universe since Stan Lee and Jack Kirby dreamed him up in Thor #132 in 1966 — a Silver Age masterstroke of imagination that only those two could have conjured. Over five decades of Marvel storytelling, this singular being has kept extraordinary company, sharing adventures with Thor, Reed Richards, and the Thing across titles including Thor and Marvel Zombies 2. Ego is the kind of concept that reminds you why the Silver Age felt genuinely limitless — when the cosmos itself could have a face, a will, and an attitude.
