Patros

Patros (パトラス, Patorasu), is an (anime only) Arrancar who rebels against Sōsuke Aizen and plans to dethrone him.

Character Outline
Patros is recognizable by his slicked back blue hair, a thin moustache, and notably sunken eyes. His mask covers the left half of his upper face, and his hollow hole is in his stomach. His outfit is similar to Ulquiorra Schiffer's, but with a high cut in the jacket that bares his hollow hole. Patros is a capable combatant, being able to match against Renji Abarai. Patros 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

After dispaching them he engages on combat with Renji Abarai. When Renji realeases his limiter Patros releases his Zanpakutō and their battle rages fiercely. With the help of the three Mod Souls Renji is able to overpower and defeat Patros.

Zanpakutō
Patros' zanpakutō is Jerifalte (ヘリファルテ, Herifarute, Spanish for "leader"). It takes the form of a normal katana with a diamond-shaped guard when sealed. The sheath and grip are yellow. Patros' zanpakutō is not used like a normal sword in combat; instead of attacking with it, Patros can fire energy blasts from long range by quickly drawing and resheathing the sword, in a style reminiscent of iaidō. The attack has twenty different levels to it, each stronger than the last (He calss this attacks in English as opposed to in Spanish something uncommon among Arrancar). The weakness of the technique is how it's performed: in order to build up the energy, Patros must sheath the sword. If prevented from doing so, the technique is rendered useless. Jerifalte's released form, activated by the command "pollute" (汚れよ, kegareyo), covers Patros' upper body in armor and grows his mask over all but the upper-right side of his head. It also transforms his right arm into a hinge-like copy of his sealed zanpakutō. His left arm, while appearing the same, opens at the middle to generate energy blasts.
