First Appearance: Mirror Of Regret (02x32)Voice Actor: Tom Fahn
A skeletal hyena monster created by Lord Zedd from the hyena picture on the cover of a magazine in the Youth Center that Shawn had been using to write a paper. He had a hysterical nature, laughing and mocking his enemies. After Adam regains his confidence, he joins the battle against Skelerena. Despite Tommy's comments that Skelerena was tough, the monster was not shown once attacking the Rangers. The Rangers receive the new Power Cannon, which easily destroys the monster.
Skelerena appears as the third boss of the Mighty Morphin Power Rangers: The Movie video game for the SNES. Skelerena could breath fire from his mouth and use his claws to attack. He also had an attack where he'd jump into the sky before crashing back down upon the Rangers. He was also very agile on top of his ski board.
