Boxer Penguin

The Boxer Penguin (ボクサーペンギン) is a creature 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. It is a large penguin with tall legs and a large beak.

With a hair-raising straight right this fighter lives on intensely cold land. With its unleashed assault it accurately punches through its prey.

Trivia

 * It resembles a cross between a Great Auk, a bird that looks like, but not related to penguins and a Magellanic Penguin due to its color pattern.
