During the Espada meeting in which Ben Tennyson's, Grimmjow insists that Ben and Ichigo should be dealt with immediately, in contrast to Ulquiorra Cifer's belief that they might be useful to Aizen's plans in the future. Grimmjow is particularly adamant after Eon reveals that Ben's strongest form, Alien X, can warp reality; he declares that, while Ben currently does not have control of the form, he might be able to gain control of it in the near future, which would make Ben unbeatable. Aizen ignores him and agrees with Ulquiorra, much to Grimmjow's fury.
Night Attack on Karakura TownEdit
Despite Aizen's orders not to proceed any further, Grimmjow takes his five Fraccion and leads a night attack on Karakura Town, determind to kill any spiritually aware person in the area. Grimmjow's Fraccion are all killed by the Shinigami sent to defend the town, whereupon Grimmjow himself confronts Ben (as Snare-oh), Ichigo, and Rukia Kuchiki. Grimmjow swiftly defeats Rukia by brutally punching her in the solar plexus and assaults the others, easily shrugging off several of their attacks, though he is unable to sufficiently damage Snare-oh. Eventually, Ben transforms into Heatblast, and he and Ichigo unleash a combined attack that leaves Grimmjow burned and scarred. Seething, he is about to attack again, but is stopped and forced to return to Las Noches by Kaname Tosen. Before disappearing into the garganta, Grimmjow introduces himself to the pair and vows that he will kill them in their next encounter with him.
After returning to Las Noches, Grimmjow is brought before Aizen to answer for his insubordination. Grimmjow is unrepentant and mocks Tosen, who angrily threatens him. Aizen, amused, refuses to punish Grimmjow for his conduct, despite Tosen's insistence that Grimmjow should face execution. Dissatisfied, Tosen severs Grimmjow's left arm instead with his Zanpakuto and destroys it with Kido. A shocked and enraged Grimmjow moves to attack Tosen, but is stopped by Aizen. Seething, Grimmjow storms back to his personal chamber.
Second Attack on Karakura TownEdit
Despite having only one arm, Grimmjow is permitted to participate in the second attack on Karakura Town. Upon arrival, he quickly breaks off from the group of Arrancar and searches for Ichigo.
Invasion of Las NochesEdit
Rematch with IchigoEdit
Thousand-Year Blood WarEdit
Sometime after the Vandenreich take over Hueco Mundo, Ben and his friends go to rescue Harribel, who was deposed and captured by Yhwach. Grimmjow offers his assistance, much to the groups' surprise and suspicion. Nevertheless, they reluctantly accept his offer. After Quilge Opie is dealt with, Grimmjow accompanies Ben and the Tres Bestias to the Vandenreich's headquarters, where he rampages through the area, causing massive destruction and slaughtering any Quincies unfortunate enough to get in his path or try to stop his rampage.
