Lexaeus (レクセウス ,Rekuseusu?) is a well-built fighter in Organization XIII's ranks, one of the two members of the Organization in Kingdom Hearts: Chain of Memories that only appear in Riku's story. He is also known as the "Silent Hero" (静かなる豪傑 ,Shizuka-naru Gōketsu?). His original self was Aeleus (エレウス ,Ereusu?, mistransliterated as Eleus in the North American version). He employs a large tomahawk, able to break rocks and shake the area itself with his earth-based powers and superhuman strength.
Lexaeus, along with Vexen and Zexion, are older members of the Organization who occupy the basement levels of Castle Oblivion in the second game. When they find Marluxia plans to overthrow the Organization by capturing and manipulating Sora, Lexaeus and Zexion decide to capture Riku and use him in the same fashion to counter Marluxia. When it becomes dangerously apparent that Sora might fall into Marluxia's grasp, Lexaeus confronts Riku directly, trying to convince him to open himself up to the power of the darkness in his heart. In the original Chain of Memories, Riku manages to defeat the warrior, but with his last bits of strength, Lexaeus releases all of the darkness within him in hopes of overwhelming and consuming Riku. In Re:Chain of Memories, however, Riku is knocked unconscious by Lexaeus, only to be possessed by Xehanort's Heartless, who swiftly cuts Lexaeus down, the dying warrior lamenting his decision to battle Riku.
