Zexion

Zexion, the Cloaked Schemer, is number VI in Organization XIII, and the youngest of the original six members. He appeared in Kingdom Hearts:Chain of Memories as a participant in the struggle within the Organization between the newer and veteran members. He was also central to the plot to use Riku as a puppet in Castle Oblivion.

Unlike the other Organization members, Zexion's weapon is unknown, and his talents lie outside of normal combat.
