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.
