Dora Laygor

Dora Laygor appeared in 1992 TV series called Kyoryu Sentai Zyuranger. Dora Laygor (ドーラレイガー Dōra Reigā): A Dora Monster who possessed a blue-jewel of great power on her crown, using it to send children to her dimensional realm where she turns them into a blue liquid. This liquid would be used to create a massive storm that would wipe out the city. Both this jewel and a red-one were sister fairy-princesses whom Bandora turned into gems. Only by the gems touching each other would the curse be lifted. Laygor was invincible until the owner of the red-jewel, Saori, slammed her jewel into the blue-jewel and broke the curse. Rendered powerless, Laygor was quickly destroyed by the Ranger Slingers.

Her name seems based on the Japanese word "Rei" which means "cold".
