Aisslinger Wernarr is an Arrancar, the seventeenth in Sōsuke Aizen's army and one of the guardians of the underground passage in Las Noches. He gave up his human form for greater power, which is why his body has an unusual structure. Aisslinger was born on November 23. He is 173 cm tall and weighs 56 kg. He died at Uryū's hands, but before his death he managed to say that Aizen fears no one, and that is exactly why the Arrancars follow him.
