Grimmjow Jaegerjaquez (Seireitou)

"Once you stepped within my territory, you lost any hope of escaping alive. You've become my prey. I will decorate this desert with your flesh and bones!"

- Grimmjow's declaration.

Grimmjow Jaegerjaquez (グリムジョー・ジャガージャック, Gurimujō Jagājakku) is an Arrancar that had once served Sōsuke Aizen as the Sixth Espada. After Aizen's defeat and the concordant fall of the Vandenreich, which left behind a vacancy over the dominion of Hueco Mundo, he became the leader of the newly established Titan. Subsequently, as the current ruler of Las Noches, Grimmjow has bestowed himself with the self-proclaimed moniker of Night King (屋王, Yaō; literally "King of the Night"); referring Hueco Mundo's constant night skies.
