Celos is a humanoid Hollow with some traits of a chameleon, green skin, large eyes, curved tail and a crest-like mask amongst them.
Talkative and enthusiastic, her attitude clashes with her nature as an advanced Menos. She is very eager to fight and witness her enemy's abilities, and she tends to mock them as long as she has the upper hand.
Celos, along with her six "siblings", has been personally chosen by Tinieblas as one of the candidates to become Vasto Lorde. She has been trained and nurtured together with the others, and eventually has achieved the pinnacle of natural Hollow evolution.
During the Shinigami mission to Hueco Mundo, she faces Captains Tarō Kinzoku and Sakamoto Risa. When she begins introducing herself, Kinzoku releases his Zanpakutō and promptly attacks her. Initially astonished, Celos quickly pulls herself together and fights him back, using his copied Shikai to do so.
Despite the Captain's ferocity, she seems to have the advantage. Eventually, when Kinzoku proceeds to unleash his Bankai, Captain Risa interfers and implores him to allow her to continue the fight instead of him. Celos acquiesces, eager to see her abilities. Subsequently, Risa tries to finish the fight quickly, but the Vasto Lorde imitates her technique and begins the duel anew.
Seeing she has no other choice to win, Captain Risa utilises Bankai, which is then promptly copied by Celos. The two fight further, and Sakamoto retorts to bolster her offence with mid-level Kidō spells. Reluctant to discard Bankai in order to easily nullify the spells, Celos struggles to counter the Captain, but ultimately fails. As she is pinned to La Aguja Blanca's wall with a Bakudō, Risa explains the Hollow her mistake and wishes her farewell before she eventually kills her.
Powers and Abilities
Envy: Celos's signature ability involves copying a single technique displayed in her vicinity, even a Bankai. She seems to wield these quite proficiently, and their power is proportional to her own Reiryoku. However, in order to emulate a new technique, she has to discard the previous one.
Hierro: Thanks to her dense Reiatsu, she can block relatively strong attacks with her bare hands.
Bala: In order to diversify her attacks without discarding a copied power, Celos can fire fast bullets of solidified Reiatsu.
Sonído Practitioner: She can utilise this technique to avoid damage or gain some distance, albeit she does so sparingly.
Great Spiritual Power: As a Menos who has achieved the peak of natural evolution, she has a large amount of spiritual energy at her disposal. Her Reiatsu has a green hue.
