Luppi Antenor/Expanded Universe

was the Sexta (6th) Espada in Sōsuke Aizen's army, having temporarily replaced Grimmjow Jaegerjaquez before his death at the latter's hands. He was later resurrected by Mayuri Kurotsuchi.

History
At some point after Luppi was promoted to Sexta Espada, Szayelaporro Granz openly speculated that Luppi was only chosen to be promoted because of his destructive nature that was similar to that of Grimmjow, and that their similarities are the true reason the two cannot stand each other.

Bleach: Can't Fear Your Own World
Several months after the Quincy Blood War, Luppi is part of the thralls deployed by Mayuri Kurotsuchi in an attempt to capture the Fullbringers residing in the Rukongai. When Grimmjow appears looking for Hikone Ubuginu, Luppi quickly recognizes Grimmjow's Reiatsu as well, and despite Dordoni and Cirucci's warnings, leaves the group to confront him.

As Grimmjow confronts the Fullbringers Kūgo Ginjō and Shūkurō Tsukishima, Luppi interrupts his fellow thralls Meninas McAllon and Candice Catnipp, and warns them to stay out of his way, making his desire to kill "the leopard" more than clear. Luppi proceeds to exert his Reiatsu and unyielding killing intent, intimidating the two Quincy, and enters his Resurrección, Trepadora. Wasting little time, Luppi fires a Gran Rey Cero at Grimmjow, who barely manages to dodge it.

As Grimmjow is surprised to find Luppi alive before him, the latter expresses his relief that Grimmjow remembers him and states his intentions to kill his usurper. Grimmjow and Luppi then proceed to exert their Reiatsu to show dominance while taunting and insulting each other. Eventually the two come to blows, and after trading a few hits Grimmjow uses a Gran Rey Cero of his own on Luppi, hitting him directly. Luppi survives his attack while only losing a few of his tentacles; delighted at his own increased power, Luppi strengthens his resolve to kill Grimmjow. As the two continue their fight, Luppi reminisces of how ever since his death and revival, he has felt nothing but an unquenchable thirst for Grimmjow's blood. Increasing the ferocity of his attacks, Luppi puts Grimmjow on the defensive, forcing the latter to enter his own Resurrección, Pantera.

In addition, he is capable of easily fending off three lieutenant-level Shinigami and a captain during the initial stages of the Espada's second invasion of Karakura Town. After being resurrected and receiving further enhancements, Luppi's Reiatsu increased to the point that it was capable of intimidating both Candice and Meninas.

Toxic Blood: As a part of his modifications, Mayuri Kurotsuchi added several of his own drugs to Luppi's bloodstream, including one that paralyzes anyone on contact.
