Coyote Starrk (コヨーテ・スターク, Koyōte Sutāku), sometimes incorrectly romanized as Coyote Stark, is an Arrancar and the Primera (1st) Espada in Sosuke Aizen's army, along with his other half, Lilynette Gingerback.

Starrk has blue-gray eyes and wavy, shoulder-length dark brown hair that he keeps unkempt and parted down the middle. He also 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. He wears white gloves. The remains of his Hollow mask consist of a fanged bottom jaw that is position along his neck as if it were a necklace. 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 he conceals with his glove.

Starrk is a lazy and unenthusiastic character who apparently spends much of his time asleep and no one, except Lilynette, appears to try and stop him from doing so. In fact, he rarely directly addresses any Arrancar other than Lilynette, his other half. Despite being the highest-ranking Espada, he is not eager to take a leadership role, shown when he easily allows Baraggan to take over at the battle of the fake Karakura Town. He is not particularly interested in whatever is going on around him, although he is surprisingly observant and a capable analyst. Unlike many of the Espada, he is not violent or overly arrogant.He initially does not seem to care a great deal for his fellows, showing no visible signs of distress or concern.

When he learns of Aaroniero Arruruerie's death, he lazily states there is nothing he could do about it, and when Baraggan and Harribel are apparently overwhelmed by their opponents' respective Bankai, he only asks Kyoraku if all the captains' Bankai are so powerful. However, this indifferent attitude seems to be dispelled with Baraggan's death. Starrk comments that it's horrible that Sosuke Aizen doesn't spare even a word for Baraggan. Starrk himself is notably affected by this turn of events, being drained of his motivation to fight.

After arguing with Lilynette for a while, he restates that he's not the type for revenge, but his desire to not see any more comrades die proves to be enough motivation for him to keep fighting. Starrk seems to be opposed to the notion of killing people, offering Love Aikawa and Rōjūrō Ōtoribashi a chance to run away instead of having him finish them off.

In comparison to the other, more serious Espada members, however, Starrk is often shown in a much more comical light, with situations often ending in him on the receiving end of physical abuse from his partner Lilynette, even though he does little to stop her actions. He can be serious on occasion, although his personality does not change much; he comes off as reluctant, but nonetheless willing to complete the task at hand. Such is the case when he was ordered to take back Orihime Inoue, despite saying he abhors such a strategy. He is fairly similar to Shunsui Kyōraku in personality, something Starrk himself acknowledges.
