[6] Deathbird debuted in Ms. Marvel #9 (September 1977), created by writer Chris Claremont and penciler Keith Pollard.

Following AIM's orders, she battled Ms. Marvel in New York one evening after Carol Danver's Park Avenue penthouse was destroyed by a bomb.

[13] It later resumed when Carol, going undercover, discovered that AIM had a secret headquarters underneath Alden's Department Store.

Deathbird decided to take the throne for herself, and allied with the councilman Samedar, alien parasites called the Brood, and renegade members of the Imperial Guard in an attempted coup.

[16] The X-Men defeated her and her allies, but not before being infected by the Brood (although they were ultimately cured thanks to the efforts of Danvers and the Acanti Soulsinger).

[17] As ruler of the Shi'ar Empire, she contended with the Starjammers and Excalibur, and sought to capture Rachel Summers, but was nearly killed by Lilandra in combat.

[18] Some time later War Skrulls impersonating Charles Xavier and the Starjammers aided Lilandra in deposing Deathbird and restoring her to the throne.

With Lila Cheney's help, she and the X-Men defeated the War Skrulls, but Deathbird ceded the empire back to Lilandra, since she had grown bored of the bureaucracy.

They managed to fend off a Phalanx assault on the Shi'ar Empire, and during the conflict, Deathbird and the X-Man Bishop forged a warrior's respect for each other.

[29] During their journeys, the two were accidentally transported to an alternate future Earth that was ruled by the evil daughter of Shi'ar Empress Lilandra and Charles Xavier.

[30] Eventually, Bishop and Deathbird return to the Sol System and encountered the inert planetary mass of the Living Monolith on their way to Terra Firma.

[39] An entry from Destiny's diary seems to imply that at least Heather was "Mothered by War," which happened to be Deathbird's Horseman moniker while she was serving Apocalypse.

The entry shows a picture of Deathbird facing off some of the X-Treme team members (Storm, Bishop, Thunderbird and Lifeguard in her Shi'ar appearance).

[volume & issue needed] Deathbird convinces Vulcan to finish the healing process that the Shi'ar members of the secret order had begun on D'Ken, who remained in a coma since the M'Kraan Crystal incident.

[volume & issue needed] During the fight Polaris crushes the ribs of Deathbird's husband and she instructs the Imperial Guard, still loyal to the ruling family, to protect them as they flee.

[volume & issue needed] At some point after Vulcan's death she was captured by a top secret organization, however they were not interested in Deathbird, but in her child - a hybrid of an atavistic Shi'ar and a Human Mutant.

[43] Sharada Darthri, the geneticist of the Providian Order, experimented on the baby and infused it with Kree geneline, thought the influx was stopped by the awakening of Deathbird, who rampaged through the laboratory.

[45] She possesses superhuman strength, speed, stamina, agility, flexibility, reflexes, coordination, balance, and endurance well beyond the average limits of her race.

Deathbird has also used other equipment of Shi'ar design, including battle armor, and a large, advanced, one-woman energy cannon.

"[48] Liz Wyatt of Comic Book Resources referred to Deathbird as an "iconic villain" of Captain Marvel.

[49] Darby Hart of Screen Rant called Deathbird one of the "best female villains" of the X-Men and a "major cosmic antagonist" of the superhero team.
