Deathbird (Cal'syee Neramani) is a fictional character. She is a Marvel Comics supervillainess, an adversary of the X-Men. Created by writer Chris Claremont and artist Keith Pollard, she first appeared in Ms. Marvel #9.
Deathbird is part of a segment of the extraterrestrial Shi'ar race that possesses talon-tipped wing. She is the hated sister of the Shi'ar empress Lilandra Neramani, 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.
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 as 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 first appeared on Earth and became an associate of MODOK and AIM 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 female fury, who got distracted by 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 either Danvers or AIM remains unknown. She did battle Hawkeye while still on Earth.
