Ghost

Ghost's History

Ava Starr is the daughter of Elihas and Catherine Starr, who gained the ability to render herself intangible and generate extreme amounts of power following a quantum accident, which killed her parents. At a young age, S.H.I.E.L.D. began taking advantage of her powers, enlisting her as a stealth operative under the moniker of Ghost prior to the HYDRA Uprising. Under Bill Foster's care, Ava realizes that she is slowly dying due to a lack of quantum energy, which she involuntarily harnesses.

Within weeks of succumbing to her disease without a cure, Ava learns that an updated version of the Quantum Tunnel, a gateway to the Quantum Realm engineered by Hank Pym has been completed, and embedded into a portable lab. Her plans to harness quantum energy from the Quantum Realm conflict with Pym's plans to rescue Janet van Dyne, whose survival in the Quantum Realm relies directly on the quantum energy Ava is seeking to extract. Ava begins making attempts to steal the lab by force, putting her in conflict again, this time with Ant-Man and the Wasp. At the verge of dying, Janet transfers some of her energy to Ava, temporarily stabilizing her abilities. With this, she slowly makes a recovery and goes into hiding with Foster.
