Big Tree

The Big Tree (ビッグツリー) 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.

An imposter of the jungle, mimicking a tree it waits for prey. To tell it apart is a near impossible task.

Trivia

 * The Big Tree is based off of the Phasmatodea, commonly known as the stick insect. While the Phasmatodea resembles small twigs and branches, the Big Tree imitates an entire tree.
