The Avengers must confront Ego, a cosmic being of immense power, whose awakening poses an existential threat to humanity. They must find a way to defeat a foe that is literally the size of a world, operating under rules and scales far beyond their usual experience.

The premise of a sentient planet threatening Earth positions this story as a high-stakes science fiction adventure.
