This category contains a list of episodes in which multiple villains are featured, such as the time Romeo worked with Night Ninja in "Catboy and the Shrinker."

Note: Episodes in which the sidekicks appear with their leader do not count as they are one group. For example, the Ninjalinos seen with Night Ninja count as a group.
