Starrk is a minor antagonist from the series Bleach. He serves as the 1st Espada in Aizen's Arrancar army in Las Noches either due to his incredibly high spirit energy or in order of when the Arrancar enlisted. Prior to being recruited by Aizen, Starrk was a singular powerful Vasto Lorde before splitting his being into two due to feeling a sense of loneliness as well as his very presence being too overpowering to those he met, even feeling some jealousy toward weaker brings. So he now lives on as himself and his other half, Lilynette, a younger green-haired female arrancar who acts similarly to a little sister to him while also being his lone fraccion within the arrancar army.

Starrk has blue-gray eyes and wavy, dark brown hair, which ends at the base of his neck, is always unkempt, and is parted down the middle. He has a faded goatee. His clothing is typical of an Arrancar: he wears a white jacket outlined in black, though altered with the collar upturned. A black sash is worn in a manner similar to a matador around his waist and he wears white gloves. The remains of his Hollow mask consist of a fanged bottom jaw which is positioned along his neck. His Hollow hole is on his sternum, right below the tip of his mask. His Espada tattoo is featured on the back of his left hand, which is usually hidden underneath his gloves.

As a naturally powerful Arrancar he is capable of basic techniques such as high speed movement Sonido, unleashing a Cero in the form of blue spiritual energy as a beam from the front of his hollow mask along his collarbone, and even going into Resurreccion form "Los Lobos" which requires merging his form and energy with Lilynette to his original form. When released his attire changes to that of a gunslinger with added features like fur trimming along the jacket collar, forearms and legs while now wielding dual pistols which Lilynette now takes the form of while retaining sentience as well as the eyepatch of her hollow mask now over his left eye.
