is a cloaked Sternritter who is the severed left arm of the Soul King. Pernida possesses the epithet "C" for , a sight-related ability that causes the opponent to collapse inward through a distortive variation of a Quincy's Blut ability invading the target's body. Pernida can also use that ability to manipulative inanimate objects and environments as well while absorbing the traits of those his Blut nerves infected. As one of the Schutzstaffel, Pernida was hidden away in Yhwach's shadow until summoned to fight Senjumaru Shutara's forces with her largest guard fatally distorted by Pernida's power before being killed by Ōetsu Nimaiya. Pernida is revived by Yhwach activating his Auswählen, facing Kenpachi Zaraki when he and Mayuri Kurotsuchi confront the mysterious Quincy who has orders to kill any intruders in the altered Royal Realm. Though he effectively takes Kenpachi out of the fight by forcing the latter to amputate his distorted right arm, Pernida is forced to discard his cloak after Mayuri deduces the Quincy's attack method and severely injures him. Pernida proceeds to use his power as the Soul King's left arm to take out Mayuri, who wants to study the entity a while more. But Pernida's regenerative abilities prove difficult for Mayuri before he uses Konjiki Ashisogi Jizō: Makai Fukuin Shōtai to create a Konjiki Ashisogi Jizō designed to counter Pernida before having his Zanpakutō eat Pernida. But Pernida destroys Konjiki Ashisogi Jizō from the inside before managing to destroy Mayuri's left arm prior to Nemu getting involved to heal her captain's arm, with Mayuri realizing Pernida's evolution ability as Nemu goes out all to protect him. But a Pernida clone manages to kill Nemu and eats her body, only to end up dying from excess regeneration due to the lieutenant's cellular makeup.
