Marluxia, the Graceful Assassin (優雅なる凶刃 Yūga-naru Kyōjin, lit. Graceful Assassin's Blade), is Rank XI within Organization XIII, the lord of Castle Oblivion and the main antagonist of Sora's story in Kingdom Hearts: Chain of Memories. He controls flowers, and uses his control to command beams of destructive energy from flower-themed minions, bombard the opponent with flurries of petals, and to attack opponents with his massive scythe.
Originally discovered by senior Organization members Xigbar and Xaldin, Marluxia is the mastermind of an internal rebellion in the Organization against Xemnas. Marluxia makes an appearance in Kingdom Hearts 358/2 Days, and is a playable character in Mission Mode.
Marluxia is voiced by Keith Ferguson.
Similar to Nagito Komaeda, Marluxia creates Kiritsugu Emiya's genocide monster clone with Kiritsugu's heartless and sadistic personality. After Kiritsugu defeats Larxene, Marluxia released Omega to kill Kiritsugu once and for all.
Marluxia created Nagito Komaeda AKA "The Hopeness" as a means to bind the Truth Stone to his soul. When Nagito served him, he look down at him as inferior and didn't take him seriously when he announced his intent to betray him. However, with the threat of Komaeda's shadow demon army, Marluxia has come to acknowledge him as a threat.
