Ego the Living Planet
Ego
A planet with a face, an appetite and a superiority complex.
Biography
Ego is exactly what the name promises: a planet-sized consciousness with a human face pressed into its crust, drifting in the Black Galaxy and considering itself the most important thing in the universe. Kirby drew him as a giant scowling world with tentacles made of its own landscape, and Thor's first encounter with him in 1966 remains one of the purest expressions of Silver Age cosmic imagination.
He has fought Thor, Galactus and the Fantastic Four, mostly by consuming things. Galactus at one point bolted engines onto his crust and used him as a mobile weapon, which is the single most humiliating thing that has happened to a sentient planet in fiction. The MCU rebuilt him entirely as a Celestial who takes humanoid form, murders his own children and seeds worlds with his genetic material, making Peter Quill's father into one of Marvel's best film villains.

Comics history
Thor #132 introduced him during Lee and Kirby's cosmic run, and he became one of the era's signature ideas: not a monster on a planet but the planet itself, with a face and an opinion. He returned to fight Thor repeatedly, tangled with the Fantastic Four, and was eventually pressed into service by Galactus, who fitted him with propulsion and aimed him at problems.
Later writers have used him to explore the outer edges of Marvel's biology, including the Black Galaxy's bizarre ecosystem. His profile exploded after 2017, when the film version turned him from an obscure Kirby oddity into a household name and a Celestial.

Frequently asked
Is Ego a Celestial?
In the comics, no. He is a living planet, a distinct type of cosmic being from the Black Galaxy. Guardians of the Galaxy Vol. 2 reclassified him as a Celestial to connect Peter Quill's parentage to the MCU's larger cosmic hierarchy.
How do you kill a living planet?
You go inside it. Both the comics and the film settle on the same answer: Ego's biology has a central nervous core, and destroying that kills the whole world. Attacking his surface is effectively pointless.
Is Ego Star-Lord's father in the comics?
No. In the comics Peter Quill's father is J'son, the emperor of Spartax. The MCU swapped in Ego, which raised the stakes from a royal inheritance to a Celestial-scale extinction plan.
