Patros is an Arrancar who only appeared in the anime, known for being one of the few who actively rebelled against Sōsuke Aizen's rule. He was part of a conspiracy to overthrow Aizen and take control himself.
You'll recognize him by his slicked-back blue hair, thin mustache, and distinctly sunken eyes. His hollow mask covers the left side of his upper face, and his hollow hole sits in his stomach. His gear resembles Ulquiorra's typical Arrancar outfit, except his jacket has a high cut that leaves his hollow hole exposed.
As a fighter, Patros is legit—he could go toe-to-toe with Renji Abarai without looking outmatched. He's got serious pride in his combat skills and loves showing off his sword technique, generally treating most opponents like they're beneath him. What really gets under his skin is the whole dynamic of Hollows having to serve under a Shinigami. That resentment toward their arrangement under Aizen apparently fueled his desire to rebel and take power for himself.
