Oozemen

Oozemen are Ivan Ooze's minions and was seen in the MMPR: The Movie.

They returned after ooze belonging to Ivan Ooze brought him back and planned his revenge against Zordon and the Power Rangers and went into his egg to wait for the right moment to strike.

When the Ninja Fighters tried to get to Ivan's egg to make sure Ivan Ooze didn't return and found it open, they faced off against the Oozemen and managed to beat them and they weren't seen after that though they were presumably destroyed after the Ninja Fighters launched Ivan Ooze (controlling Hornitron) into Ryan's Comet and onto the sun.
