Aaroniero Arruruerie

Aaroniero expresses some amount of pride in his ability to "continue evolving" and his position as an Espada, despite his Gillian status. Somewhat cruel and sadistic, Aaroniero enjoys toying with his opponents, particularly those he has information on from his absorbed memories, asking Rukia to kill her comrades to make up for Kaien's death. Interestingly, his two heads have a degree of individuality, since they refer to themselves in plural when exposed, and each reacted differently to the idea of death

Aaroniero is a main antagonist from the series Bleach. He is ranked the 9th espada among Aizen's arrancar army and not like a traditional arrancar like his comrades. In his past he was a Gillian hollow before joining Aizen, he is an amalgamation of countless other hollows in one that Aaroniero devoured with his zanpakutou including one who had devoured a particular soul reaper named Kaien Shiba, displaying that he can transform into the likeness of others even Kaien. Aaroniero is garbed in a long white arrancar robe and hakama with a large frilly collar that helps conceal part of the cylindrical jar filled with red liquid that contains both ball-shaped heads of Aaro and Niero, both of which possess individual personalities. Unlike other arrancar whose zanpakutou are swords, his is solely a tentacle appendage with a gaping mouth concealed in his sleeve in place of a forearm. Upon going into resurreccion form, Glotoneria, the only difference is Aaroniero's lower body is replaced and infused to a purple fleshy mass of numerous octopus tentacles as well as sinular eyes on two sides of the mass which have individual gaping mouths. Despite not being like a traditional arrancar, he still also possesses natural abilities as one.
