What Happened To Everyone Who Became Horsemen Of Apocalypse?
11. Deathbird
Another of Horseman of Apocalypse who joined his ranks during the events of The Twelve, Deathbird already had a history of being a nasty piece of work long before that comic came to pass.
A member of the Shi'ar Empire, Deathbird was the treacherous sister of Empress Lilandra, and was repeatedly foiled in her attempts to usurp the throne by the Imperial Guard, the X-Men, and occasionally even the Starjammers.
Bizarrely, it was actually a period where Deathbird wasn't all that evil where she found her way to Apocalypse. She was involved in a brief romance with Bishop, but she betrays him to the Skrulls, who are themselves aligned with En Sabah Nur. Deathbird is then betrayed by Apocalypse in turn, and is transformed into the new War.
Deathbird ultimately flees once Apocalypse is defeated though, and eventually even marries the third Summers brother, Gabriel.
