Vexen, the Chilly Academic
"I'm a scientist. Experiments are what I do, yes." - Vexen
Vexen, the Chilly Academic (いてつく学究 Itetsuku Gakkyū), is the Nobody of Even and the Rank IV member of the original Organization XIII. He controls ice and uses it to command storms and blizzards, freezing his opponents solid, while defending himself with his massive shield. Vexen was the highest ranking member of the Organization inside Castle Oblivion, but ironically he is the first Organization member to be eliminated. He creates the Riku Replica and uses the Replica to carry out several experiments on Riku and Sora. Vexen appears in Kingdom Hearts Chain of Memories, and in Kingdom Hearts 358/2 Days as a playable character in Mission Mode.
