Character from Kingdom Hearts by Tetsuya Nomura / Square Enix & Disney
The Luna Diviner — Organization XIII's cold second-in-command who draws power from the moon and secretly plotted with Axel to overthrow Xemnas before their friendship shattered.
Saix is ice where Axel is fire — calculating, emotionless, and utterly devoted to his goals. As Xemnas's second-in-command, he managed the Organization's day-to-day operations with ruthless efficiency, dispatching members to their deaths at Castle Oblivion without hesitation and manipulating Sora's emotions by dangling Kairi as bait. But Saix was not always this cold. As Isa, he was Lea's childhood best friend in Radiant Garden. Together, they infiltrated Ansem the Wise's castle. Together, they became Nobodies. And together, they plotted to overthrow Xemnas from within. But the plan required sacrifice — required Saix to become something monstrous — and somewhere along the way, the mask became the face. His berserk mode under moonlight transforms him from a cold strategist into a howling, unstoppable berserker — a werewolf in all but name. His final defeat in Kingdom Hearts III breaks the mask at last, and Isa weeps for the friendship he destroyed to chase a heart he already had.
A tall figure with long, frayed dark blue hair slicked back in wild spikes, amber eyes, and a distinctive X-shaped scar between his eyes. He wears the standard black Organization coat. In battle, he wields a massive claymore called Lunatic. When berserk under moonlight, his eyes turn completely yellow, his scar becomes jagged, and his hair grows wild.
Also known as: Saix, Isa, The Luna Diviner, Number VII
