Marluxia, working with Larxene and Axel, plots to overthrow the Organization. They formulate a plan to use a young girl named Namine, who has a mysterious power over memory, to deceive Sora into thinking he had sworn to protect her, and then have her use Sora to help them defeat the senior Organization members. This plot stems from a rivalry between some of the younger Organization members and the original six core members.
Marluxia, Vexen, Axel, and Larxene all do their part to feed Sora with information and lure him further into the castle. Each of them fight him on their own, although none of them use their full strength and throw the fights. They also make use of Vexen's Riku Replica to compete with Sora for Namine's loyalty.
Marluxia and Larxene eventually learn that Vexen has been reporting back to Lexaeus and Zexion regarding their revolt. After Vexen loses control of the Riku Replica, Marluxia pronounces his project a failure. Although Vexen arrogantly protests that Marluxia has no business speaking to him in such a manner, Marluxia claims that his mastery over Castle Oblivion allows him the authority to do so.
Marluxia threatens to tell "the Superior" of Vexen's failure, but Vexen pleads with him not to do so. Marluxia agrees not to if Vexen eliminates Sora. Although confused by the order, Vexen agrees, and heads Sora off in the Twilight Town world. He fights Sora for the second time, but is again defeated. Before he can reveal Marluxia's plans to use Sora, however, Axel destroys him on Marluxia's orders, making Vexen the first Organization member to be eliminated.
"Your project has failed, Vexen. Do not disappoint us again."
