Szayel was present at the Espada meeting when Ben Tennyson arrived in Hueco Mundo and entered Las Noches. Like the others, he was visibly surprised when Ben used the Ultimatrix against Yammy. After Aizen tricked Ben into serving him, Szayel introduced himself to Ben, saying that he was looking forward to observing him, much to Ben's discomfort. When Aizen asked Ben to show the group all of his forms and Ben was about to reluctantly comply, Szayel interrupted, saying that such a thing would be boring and suggested that Ben show more of his forms through combat, a suggestion that Aizen ultimately agreed with. Ben revealed more of his forms through fighting the Privaron Espada while Szayel watched with delight.
Szayel would continue to observe Ben as the latter revealed more of his forms. One early occasion was when Ben was sparring with Tia Harribel's Fraccion (having joined them). He initially attempted to conceal his presence, but Harribel easily detected him and he revealed himself. He voiced his regret that Aizen would not allow him to study Ben up close, to which Harribel responded by coldly threatening violence against the mad scientist if he attempted to harm Ben, but Harribel brushed her off, saying he would do nothing of the sort. Szayel was disappointed that Cannonbolt was not extremely unique in some ways, but became more intrigued when he saw Ben use Upchuck to spit a Cero at Apacci Emilou. He made note of how familiar that particular maneuver looked to Nnoitra Jiruga, whom had also come to watch, reminding him of Nelliel Tu Odelschwanck, though he did not mention her by name.
Invasion of Las NochesEdit
Battle with BrainstormEdit
Szayel recovered from his defeat by eating one of his Fraccion, as they had been designed as such. He tracked down Nnoitra, whom had been handed a brutal defeat by Ben as well, and healed him. Accompanied by Nnoitra's Fraccion, Telsa Lindocruz, Szayel and Nnoitra ambushed Ben and his friends, with Szayel perversely revealing the nature behind his regeneration, much to Ben's disgust.
Szayel was killed by Mayuri, though how Mayuri killed him is not known. His death was confirmed by Ulquiorra Cifer, and out of all the deceased Espada, Szayel's death was the only one that Ben did not mourn.
