Sōō Zabimaru, Zaga Teppō

is a technique of Renji Abarai's true Bankai, Sōō Zabimaru.

Description
After impaling the enemy with his blade, Renji clenches his fist, forming a jaw of spiritual energy behind him. These jaws close down on the enemy, forming the visage of a large, serpentine skull, crushing them with its fangs. Simultaneously, Renji fires a blast of spiritual energy through the enemy. The attack is powerful enough to reduce its target to ashes.
