Coyote Starrk

Coyote Starrk is one of the most powerful characters in Bleach, serving as the Primera Espada (Espada #1) under Aizen's command.

Brief description:

• He is an Arrancar who was originally an extremely powerful Hollow whose mere presence was so overwhelming that other Hollows would instinctively die or disintegrate around him, leaving him in perpetual loneliness.
• Personality-wise, Starrk is laid-back, melancholic, lazy, and surprisingly polite. He dislikes fighting and would rather sleep or avoid conflict, but he is fiercely protective of his only companion, Lilynette Gingerbuck (who is actually a part of his soul split off from him).
• In combat, he is extraordinarily powerful, possessing immense spiritual pressure, incredible speed, great swordsmanship, and the ability to fire powerful Cero blasts with ease.
• His Zanpakutō is named Los Lobos ("The Wolves"). When released, he gains a wolf-themed Resurrección, dual pistols that fire Cero Metralleta (a rapid-fire barrage of Ceros), and can summon powerful wolf-like spirit wolves that explode on contact.

Starrk is generally considered one of the most tragic and sympathetic Espada due to his deep loneliness and desire for companionship rather than destruction.
