Monster Creation

This article is about a recurring event in the Super Sentai and Power Rangers franchises.

A staple in Super Sentai and Power Rangers is the plethora of episodic monsters, most of which are created by the main villains through various means. However, there are some monsters that are simply recruited to the group or are already lesser members, and in some cases it is never revealed how the main villains are supplied with monsters.
