౨ৎ Ava Starr/Ghost

Ava Starr is the daughter of Elihas and Catherine Starr, and a founding member of the New Avengers. During her childhood, she 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 Hydra's uprising. Under Bill Foster's care, Starr realized that she was slowly dying due to a lack of quantum energy, which she involuntarily harnessed.

Ava Starr is a tall, slim woman with long curly brown hair (usually in a low bun) with a tan-skinned tone and green eyes. She has an English accent. Besides her suit, she tends to go for loose, dark colored clothing, like hoodies, band tees, and sweatpants.

She is shown to be sarcastic to other people sometimes, when she interacts with people she knows. She can show determination of how to work together as team when the Void persona inside the Sentry who was terrorizing Manhattan and was able to protect as many civilians as possible reducing collateral damage. She cares about others, even if she doesn't show it. She can be sometimes grumpy and is NOT a morning person. Will have a grudge if someone eats her leftovers. Gets mad when Yelena steals her clothes yet does the exact thing to Bob (his sweaters are very comfy). She doesn't like talking in great detail about her feelings, usually brushing it off, but does bring up her past from time to time in her usual sarcastic tone.

Within weeks of succumbing to her disease without a cure, Starr learned that a Quantum Tunnel had been created by Hank Pym and embedded into a portable lab. Her plans to absorb energy from the Quantum Realm conflicted with Pym's plans to rescue Janet van Dyne, whose survival in the Quantum Realm relied directly on the energy Starr sought to extract. Starr began making attempts to steal the lab by force, putting her in conflict with Ant-Man and Wasp. Upon her return, Janet transferred some of her quantum energy into Starr, stabilizing her affliction. With her pain healed, she went into hiding with Foster.

On the run from fifteen nations, Starr found herself under the employment of Valentina Allegra de Fontaine, working as a shadow operative for O.X.E. When de Fontaine was faced with incoming impeachment, she sent Ghost and her other operatives to kill each other in an attempt to get rid of any incriminating evidence. Following a brief battle, where Ghost murdered Taskmaster, the group learned the truth and agreed to work together to escape. Ghost, now teamed with Yelena Belova, U.S. Agent, Red Guardian, and Winter Soldier, decided to take down de Fontaine and stop her plans to use Bob Reynolds as her own weapon. The team saved Manhattan from Void, and de Fontaine publicly declared them as the New Avengers.

As a child, Ava Starr grew up in Argentina as the daughter of Catherine and Elihas Starr. Starr witnessed the fallout of her father's partnership with Hank Pym, who kicked him out of S.H.I.E.L.D. and smeared his name within the scientific community. Embittered, Elihas continued to research quantum energy on his own, despite the risks. When an experiment involving the Quantum Tunnel went wrong, Starr tried to run to her father to ensure he did not die alone, but the tunnel ruptured before she reached him, killing her parents and inundating her with quantum energy.

When the Fire Department arrived, they were unable to touch Starr as she had become intangible from the accident. Starr was placed in an orphanage and later met her father's ex-colleague Bill Foster, who gave her a teddy bear. Although she was upset for her inability to hold the toy, Foster encouraged Starr to focus her powers, eventually allowing her to solidify and pick it up. Foster promised to find a way to cure her condition and began to act as a surrogate father to Starr, developing the quantum chamber to allow her to briefly stabilize and ease her pain.

Observing the potential asset her powers could become, S.H.I.E.L.D. took Starr and began to train her in espionage so that she could go on missions to take down threats that proved too difficult for conventional operatives. They developed the Ghost Suit for her to harness her abilities, granting her the option to slip between intangible and solid states, and promised to help find a way to cure her.

Even with the suit, it still caused tremendous pain and wasn't a long term solution. She went after a chamber in a lab that could help cure her, but failed, but was healed by a woman who had powers from being trapped in the quantum realm.

While on the run, Ghost was encountered by Valentina Allegra de Fontaine, who recruited her to work for O.X.E., undergoing shadow ops assignments. Ghost was provided with a new suit to help her control her powers, which she utilized to complete various assassination and infiltration missions.

After being sent on a new mission, she quickly realized that Valentina had confused all of them (Yelena Belova, John Walker, Taskmaster) to eliminate themselves since they were "loose ends." Although, they all survived, except Taskmaster. They met Bob Reynolds, a civilian who was chosen for an experiment from Valentina, although he couldn't remember it at the time. Valentina once again tried to kill them, but was unsuccessful and took Bob back to the Tower, to manipulate him into using his powers to kill the rest of them. He refused to, and was "terminated" with a kill switch and then transformed into the Void, a entity revolving around his trauma and depression. The team fought by his side, and won, and Valentina forced them to become the New Avengers (or Thunderbolts). Bob lives at the Tower, not using his powers as the Void could still come out and hurt others.

Ava Starr has been trained by S.H.I.E.L.D. to become an elite and ruthless stealth operative tasked with infiltrating and eliminating criminal organizations, terrorist cells, and other threats.

When the Void went on a rampage in Manhattan, Ghost alongside the rest of the Thunderbolts made a desperate attempt to save as many innocent civilians as she could, notably without needing any encouragement from others but by her own volition. After Belova had seemingly sacrificed herself to the Void, Starr was the first to express desire to go into the Void to go after Belova, even though she had no proof Belova was still alive. Despite having felt insulted earlier by Belova's outburst after the Thunderbolts lost to Sentry, Starr still expressed desire to find her and save her, showing her attachment to the Thunderbolts despite her attempts to appear unconcerned beforehand. She understood that violence would not stop Void's rampage but rather showing Bob compassion and empathy would.

Her entire state allows her to phase through things and move faster when she is in phase; she can generate zero friction and resistance and is able to stay in this state for around a minute. She turns invisible, practically transporting in small distances. While phased, Starr can move at speeds greater than a normal human. Starr can phase through solid objects and living beings at will. The use of her powers is accompanied by flickering, prismatic afterimages of her body as she quantum shifts through space. With the aid of her suit, she can choose whether to become solid or intangible, which allows her to quickly evade attacks and counterattack in tandem.

Her other abilities include: martial arts, knife mastery, acrobat, marksman, spy, assassin.
