Chosan (Invasion of the Cat-People) was one of the Cat-People who, under Queen Aysha's command, invaded Earth in search of Euterpian beacons.
Chosan was killed by the energy backlash when the Cat-People's ship unintentionally attacked Aysha, who was returning via Thorsuun's reverse tachyon-chronon unit. (PROSE: Invasion of the Cat-People)
