Quimera Parca

is a collaborative technique used by the Arrancar Emilou Apacci, Franceska Mila Rose, and Cyan Sung-Sun, which results in the creation of the bipedal monstrosity Ayon.

Description
After viciously amputating the majority of their left arms, the three Arrancar combine these severed limbs to produce a creature of monstrous proportions named Ayon. This creature towers over average-size combatants and boasts considerable offensive abilities, possessing both inhuman durability and immense physical strength. Despite some very limited sentience, Ayon is apparently ignorant to its creators' instructions. However, it does seemingly express a small amount of concern to their current conditions, only evidenced after they were severely injured.

Ayon's appearance is an amalgamation of elements taken from each of the Arrancar's appropriately themed Resurreccións. These include a deer-skull for a nose, cloven-hoofed legs, a massive muscular torso, a long black mane, and a large serpent for a tail.

Whilst this technique could originally only be performed once all three had adopted their respective Resurrección, in the time since Sōsuke Aizen's defeat and the ability's next use, they have become capable of executing it in the same manner even within their normal forms.

Censorship
Due to the graphic nature in which this technique is performed (amputating of the arms of its users), its depiction was drastically altered in the anime. Rather than severing their left arms, they instead simply hold them outwards before firing red beams which converge and become Ayon. When observed later, their left arms are absent with a red aura covering the area where it would have been removed.
