Patros

パトラス

Patros is the only Arrancar in the anime who rebels against Sousuke Aizen and plans to dethrone him.
He is recognizable by his slicked-back blue hair, a thin mustache, and notably sunken eyes. His mask covers the left half of his upper face, and his hollow hole is located in his stomach. His outfit resembles Ulquiorra Cifer's, but features a high cut in the jacket that exposes his hollow hole. Patros is a capable combatant, able to match Renji Abarai. He shows great pride in his ability, flaunting his powerful sword draws and generally treating opponents as trash. Patros hates the fact that, as Hollows, they have to serve a Shinigami.
