Use of power ring/gem grants: Caroline "Carol" Ferris is a fictional character appearing in the DC Comics Universe.

She is one of many characters who has used the name Star Sapphire, and the long-time love interest of Hal Jordan, the Silver Age Green Lantern.

Kari Wahlgren, Jennifer Hale, Olivia d'Abo, and others have voiced the character in animated television series and films.

When the Zamarons discover that she is in love with Green Lantern, a servant of their estranged friends, the Guardians of the Universe, they brainwash her with the ring of the Star Sapphire, and command her to destroy him.

In this retelling, the two first meet when they are eight, as they watch Hal's father, Carl Ferris' best friend, experience mechanical problems with his plane.

Hal hated Ferris for what happened to his father, but, after discovering the truth, he and Carol find solace in each other's grief.

[6] When Carol Ferris is cured of her evil Star Sapphire persona, she develops a third subconscious identity, the male "Predator".

Deprived of Hal Jordan's love at the time, Carol finds everything she wants from a man in the Predator—masculinity, strength, and care.

Physically separated from Carol's body, the Predator repeatedly appears as a mysterious figure, protecting Ferris Aircraft from the threats of Eclipso, the Demolition Team and Jason Bloch.

In the third Green Lantern series, the nature of the Predator entity is retconned as being a parasite creature from the planet Maltus.

But her time under the creature's control, along with the destruction of Coast City and the discovery that her father faked her mother's death, causes Carol to reject a distraught Hal Jordan.

She realizes that Star Sapphire was not a subconscious identity created by her, but an energy-based being who inhabited her body.

Shortly after she gives birth, Neron appears and offers to purge her of both Predator and Star Sapphire.

Carol agrees, and then watches as the now separate entities are killed by Neron, who departs with their baby in his arms.

Blackest Night #1 establishes that in an untold story, Carol gets free of the Star Sapphire persona sometime before Katma Tui's death.

He hands the gem to Carol and lets her finish the job, which she does (essentially finally killing the Star Sapphire persona that would take control of her), and starts feeling much better.

Carol refuses to accept the ring, which shows her a vision of the War of Light and indicates that Hal Jordan will not survive.

The fight takes a turn when Carol attempts to encase him in one of the brainwashing crystals that the Zamarons use to "recruit" new followers.

Before he can capitalise on the advantage, the Black Lanterns invade, led by Amon Sur, shocking both Carol and Sinestro.

The group escapes Zamaron moments before Black Lantern rings reanimate the bodies of the two beings whose love fueled the Star Sapphire's central power battery, devastating the planet in the process.

Eventually, she deputizes Wonder Woman as a temporary Star Sapphire, due to her great ability to feel love, thus undoing Nekron's control of the Amazon.

In an attempt to stop the Spectre, Hal releases Parallax's essence, deciding to join with him again to fight back.

[23] She is in Las Vegas where she takes on the Predator who has possessed a man who is infatuated with a young woman to the point of obsession.

Carol, having renounced her role as a Star Sapphire (although she retains her power ring), bails Hal Jordan out of jail after he saw a woman being attacked on a film shoot and thinks it's real.

[37] In the illusions of Carol, she is battling the Atlantean warship on the carrier, but she eventually regains her Star Sapphire ring and escapes from the First Lantern's influencing powers.

[40] Despite her past with Hal, Carol goes on to develop feelings for Kyle as she spends more time with him as he explores his White Lantern abilities, to the extent that she is one of the few people aware of his survival after he seemingly sacrifices himself to recharge the emotional spectrum.

[41] Carol Ferris has broken up with Hal Jordan for unknown reasons, has given up her power ring, and is dating Nathan Broome.

[43] Hal Jordan's recent actions with Sinestro has caused Ferris Air to lose all of their military contacts which makes her company nearly bankrupt.

While slightly intoxicated at a bar, she asks Nathan to marry her, and they travel to Las Vegas to hold a make-shift ceremony at a superhero theme chapel.

[57] Star Sapphire was ranked fourth on Comicverse's "Top 5 DC Comics Villains Turned Heroic" list.
