Coyote Starrk

is an Arrancar in Sōsuke Aizen's army, and one of the top three most powerful Espada.

Arrancar Arc
Stark is briefly seen as a shadowy figure for a short period of time observing Aizen creating Wonderwice Margera.

Hueco Mundo arc
He next appears when the Espada are gathered by Aizen about Ichigo Kurosaki, Yasutora Sado and Uryu Ishida entering Hueco Mundo to save Orihime Inoue, apparently sleeping right before it. He is later seen sleeping when the 9th Espada Aaroniero Arruruerie is killed by Rukia Kuchiki. His Fracción, Lilinette, wakes him up and informs him of the event but Stark already knows about it. Lilinette urges him to do something, but Stark simply replies: "What do you want me to about it?"

Later, after Las Noches is invaded by the Gotei 13 and the 8th, 7th and 5th Espada are killed in battle, he appears suddenly before Orihime to bring her back to Aizen. He appears reluctant to do so, as he comments he feels uncomfortable doing such a thing. Regardless, he brings her back to Aizen, just as he begins to set his plan to destroy Karakura Town into motion.

Fake Karakura Town arc
After Aizen travels to Karakura Town he is met with resistance by the other Gotei 13 captains currently not in Hueco Mundo. Aizen summons Stark, along with Lilinette, to the fake Karakura Town along with the two other strongest Espada to do battle with the Gotei 13. When Yamamoto uses his Shikai to trap the opposing captains, Aizen, Ichimaru, and Tōsen in his shikai, he narrowly avoids the attack. When Barragan himself decides to take control of the situation, tells Stark to "not have a problem with that", he lazily agrees, which earns him a kick from Lilinette. Currently he and Lilinette are seemingly about to engage in battle with Captain's Jūshirō Ukitake and Shunsui Kyōraku. Stark even goes as far as to ask if they can "pretend to fight" until it's over. Ukitake is surprised by this suggestion, but Kyōraku gleefully states that it is an excellent idea. But he declines the offer, saying that he must fight, likely because of the knowledge of what's at stake. Stark lazily remarks "What a pain" and draws his sword ready to battle.

Appearance
He resembles Shunsui Kyōraku in looks and demeanor in that he is lazy and easy going. His shoulder-length hair is dark and parted down the middle. He also has a goatee. The remains of his hollow mask consist of a bottom jaw that is positioned like a necklace. His hollow hole is on his sternum, right below the tip of his mask.

Personality
Stark is a male arrancar who appears to be very lazy; he is seen sleeping when the Espada learn of Aaroniero Arruruerie's death, and does not appear overly concerned by the news, stating there was nothing he could do it now.

In comparison to the other more serious Espada members he is often shown in a much more comical light, with situations often ending in him on the receiving end of physical abuse. When he is shown to be serious however his personality changes completely; he comes off as reluctant but nonetheless willing to do what has to be done to complete the task at hand. Such is the case when he was ordered to take back Orihime despite saying he abhors such a strategy.

Powers & Abilities
Sonido Master: Starks' abilities have yet to be seen other than a form of teleportation (or most likely, a very skilled usage of Sonido) used to avoid both Kenpachi Zaraki's and Ichigo Kurosaki's attacks and to recapture Orihime, returning her to Aizen within an instant. Cero:

Great Spiritual Power:

Zanpakutō

 * Resurrección

Fracción

 * , is a female arrancar who seems quite mischievous, in that she enjoys waking Stark up in unusual ways: first by shoving her fist in his throat, then by squeezing his testicles. Despite her initially childish behavior, she does seem to show some concern for the ominous occurrences in Hueco Mundo. Currently she is with Stark in the fake Karakura Town.

Trivia

 * In German, 'Stark' means strong or heavy. In accordance to fashion, 'Stark' means cool.
