Yaksha

Yaksha is a creature who belongs to Mystique Sonia. He is usually worn by Sonia as a hat, although he sometimes works independently. Whenever Mystique Sonia gets mad to abandon Yaksha, he temporarily worn by Mighty Ray.

A former tank driver was transformed into a Yaksha when he fell in love with Mystique Sonia and came under her curse, which transformed him when he told her that he loved her three times. He took the place of a Yaksha who worked with Sonia until his passing in Liger Castle. It's as of yet unknown if the same Yaksha is reborn when one passes away.
