Madame Woe

Madame Woe is an elemental monster. She gets her name from bringing woe or trouble to everyone she touched. Madame Woe's jewel allowed her to control wind, rain, heat, and cold and could send people to other dimensions.

It is unclear how Madame Woe came into existence. Rita Repulsa contacts Woe and asks her to come to the palace, yet at another earlier Rita seems to infer that Finster is responsible for creating her, as she asks him to create a monster, and when he asks which one, her response is "a Madame Woe". Though it's likely Finster created Madame Woe some time ago before Rita and her minions were trapped in the space dumpster, and she's been stranded on Earth since.

She was defeated when Billy ripped the crystal off of her head, crumpled it, freeing the other Power Rangers and Marge. They then used the Power Blaster to finisher her off.
