Ichimaru Gin is a badass captain who destroys any enemies in his way. Ichimaru Gin was believed to have killed Aizen, a different captain, but later we found out that Aizen's dead body was an illusion.

Ichimaru is always smiling and mocking others. Some characteristics of him include his annoying smile, his eyes that never show, his cocky attitude, and his eyebrows. When other Shinigami find out he's evil, one says "Damn Ichimaru he has funky eyebrows!"
