Invasion of Las NochesEdit
Mayuri is present at the captains' meeting to discuss the mysterious shapeshifter. When Paradox arrives and explains Ben's presence and the power of the Ultimatrix, Mayuri becomes excited and clearly desires to study Ben.
Escorted by Paradox, Mayuri arrived at Hueco Mundo to assist the heroes in the battle against the Espada, accompanied by his lieutenant, Kenpachi Zaraki, Yachiru Kusajishi, Byakuya Kuchiki, Retsu Unohana, and Isane Kotetsu. Mayuri, Kenpachi, Nemu, and Yachiru specifically arrived at the spot where Ben, Nelliel Tu Odelschwanck, and Uryu Ishida were battling Nnoitra Jiruga, Tesla Lindocruz, and Szayel Aporro Granz.
Mayuri introduced himself and expressed an interest in studying Ben, noting that Brainstorm in particular had piqued his curiosity. When Ben asked how Mayuri knew of the form, Mayuri revealed that he had observed the former's previous fight with Szayel through miscroscopic surveillance cells he had infected Uryu with in a previous fight, much to the latter's outrage. After Ben and his friends left, Mayuri battled Szayel in Ben's place, killing the Espada without much trouble, though it is not shown specifically how he did so.
After Ben defeats Sosuke Aizen using Alien X, Mayuri arrives at Fake Karakura Town with several other Shinigami, and quickly becomes interested in studying Alien X, becoming more and more eager to do so with each detail he hears. He also expresses his wish to test the possibility of Arrancar being able to procreate with humans, much to Ben's embarrassment and causing Nelliel and Tia Harribel to imagine what having children with Ben would be like.
