Black Brothers

The Black Brothers (ブラックブラザーズ), are three brother scorpion-like creatures developed by Dr. Indigo for Shiki's plot to use monstrous animals to attack East Blue to force the World Government to submit to him.

A trio of stingers, each brother has a different appearance from each other.

Big Sasori (巨大サソリ) is the eldest son of the three brothers. Working in conjunction with his brothers he soundly brings down his prey.

The second son is characterized by his sharp form, pincers, and stringer. Using his sharp pincers he tears his opponents to pieces.

The third son has on his single tail two stingers. He overpowers by using his thick and heavy build.

Trivia
