Monkey Trooper

The Monkey Trooper (モンキートルーパー Monkī Torūpā) is a creature developed by Dr. Indigo using the chemical SIQ for Shiki 's plot to use monstrous animals to attack East Blue to force the World Government to submit to him.

A weapon master, this armed monkey picks up and uses man-made weapons. He masters swords, needless to say guns as well.

It appears in One Piece Film: Strong World, after the animals from Merveille are summoned to the main island, and after they've invaded Shiki's palace. One was seen trying to fight Sanji, but is defeated with a single kick.
