Coyote Starrk

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. 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.

Stark is an Arrancar in Sōsuke Aizen's army. He is as stated in an interview by Tite the Primero Espada. Stark resembles Shunsui Kyōraku in looks and demeanor in that he is lazy and easy going. Stark is first shown during Aizen's meeting about Ichigo Kurosaki, Yasutora Sado and Uryu Ishida entering Hueco Mundo to save Orihime Inoue, apparently sleeping right before it. Then he is later seen sleeping when the Noveno Espada Aaroniero Arruruerie is killed by Rukia Kuchiki.

Tite Kubo also stated that Stark will not fight Ichigo or any Captain, yet he will fight someone else. What Kubo meant by this however, is, as of yet, unknown.

Abilities
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.

Lilinette
Stark's Fracción, Lilinette, 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.
