Nobody 11 MarluXia

A relatively new recruit to the Organization, courtesy of Xigbar, Marluxia (マールーシャ, Mārūsha^?) is lord of Castle Oblivion and Sora's main antagonist in Kingdom Hearts: Chain of Memories. He is also referred to as the "Graceful Assassin" (優雅なる凶刃, Yūga naru Kyōjin^?, lit. "Graceful Assassin's Blade"). Marluxia is voiced by Tatsuya Kando in Kingdom Hearts: Chain of Memories^[12] and Shūichi Ikeda in Kingdom Hearts Re: Chain of Memories. He uses a scythe and his control over flowers to attack.^[4]
In Chain of Memories, Marluxia and Larxene conspire to
overthrow the Organization by using Naminé to manipulate Sora's
memories. He gives Sora his first set of world cards to proceed through
the castle. He assigns Axel to eliminate Vexen when his plan to use the
Riku Replica fails. Larxene fails to kill Sora and is eliminated as
well. Marluxia is later confronted by Axel, who accuses Marluxia and
Larxene of being traitors for conspiring against the Organization. Axel
attempts to kill Marluxia, however, Marluxia returns to the thirteenth
floor with Naminé, tricking Sora into fighting Axel for him. Seeing
Axel defeated, Marluxia anticipates Sora's arrival on the thirteenth
floor. He orders Naminé to erase Sora's memories, but she refuses. When
Marluxia implies that he will kill her for disobeying him, Sora demands
that Naminé erase his memories for her safety, as his promise will
remain and he can protect her. Marluxia says that Sora would become
just like the Riku Replica, but the Riku Replica surprises Marluxia,
who then engages Sora. The two fight, but Sora realizes he has been
fighting a replica of Marluxia. He later finds the real Marluxia, in a
new form, and kills him.
