Deathbird (Cal'syee Neramani-Summers) is a fictional character appearing in American comic books published by Marvel Comics. Created by Chris Claremont, John Byrne, and Dave Cockrum, she is usually depicted as a supervillain, an adversary of the X-Men. Deathbird is part of a segment of the extraterrestrial Shi'ar race that possesses talon-tipped wings. She is the hated sister of the Shi'ar empress Lilandra Neramani, the mother of the Shi'ar warrior, Deathcry, and constantly seeks to usurp her sister's throne. She is also a sister of D'Ken, the first depicted ruler of the Shi'ar. Publication history Created by writer Chris Claremont and artists John Byrne and Dave Cockrum, she first appeared in Ms. Marvel #9. Fictional character biography Deathbird was born Cal'syee Neramani to the ruling house of the Shi'ar Imperium on the Aerie (now known as Chandilar), native world of the Shi'ar. Her name was stripped from her after it was prophesied that she was destined to commit great evil. She was exiled after brutally murdering both her mother and an unnamed sister. During this exile, she traveled on Earth and became an associate of MODOK and A.I.M. at some point. 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. The skirmish was interrupted after Deathbird severely injured the superhero, who became distracted trying to save the lives of two small children. It later resumed when Carol, going undercover, discovered that AIM had a secret headquarters underneath Alden's Department Store. The battle between the two seemingly ended with Deathbird's demise and MODOK's escape after betraying her. Whether Deathbird sought revenge on AIM remains unknown. She did battle Hawkeye while still on Earth. She battles Ms. Marvel again. Some time later, her younger sister Lilandra became Majestrix of the Empire following the events that left their brother, D'Ken, comatose. 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. 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). She later succeeded in deposing Lilandra with the aid of the Brood, and took the throne for herself. As ruler of the Shi'ar Empire, she contended with the Starjammers
