Kingdom Hearts: Chain of Memories

The Organization make their first appearance in the series (apart from Xemnas's appearance in Kingdom Hearts Final Mix). The neophytes, Marluxia and Larxene, tried to take control of the Organization by using Sora as their puppet by having Namine rewrite his memory, while the senior members, Zexion, Lexaeus, and Vexen, tried to oppose them by using the darkness in Riku. However, all of them, save Axel, who was sent to kill traitors in the group, were eliminated.
