Deathbird (X-Men: The Animated Series)

Cal'syee was seen at D'ken's side when Christopher and Katherine Summers were abducted.

Following Lilandra's ascension to the throne of the empire, Deathbird sought to overthrow her sister and install herself as Majestrix, for which she joined Apocalypse. However, Apocalypse was merely using Deathbird for his own plans.
