The Chained Ninja is a Mini Boss enemy that appears somewhat often in Quetzelcostl. This creature has the AI of a Ninja enemy, and uses chains and kitchen knives to its aid. This enemy can also be found in the Netherlands while getting the good ending. While this seems like a totally random enemy, its actually based off the Chained Monstrosity, while having the chains and fleshy look. Technically, these enemies are spawns of the Chained Monstrosity.
