Canon
In the past life Beryl seemed to have a thing for Prince Endymion. After being reincarnated Queen Beryl abducted Tuxedo Mask and brainwashed him to fight as Prince Endymion for the Dark Kingdom.

He is eventually freed from her control and injured her with a rose forcing her to fuse with Queen Metalia to become Super Beryl who is later slain by Sailor Moon.
