"From Kamen Rider J".

Garai ( ガライ ):

The oldest of the Fog Mother's children, assuming the form of a youngman. He is called the "Prince" from the Fog Mother. His true form is Cobra Man. An armored cobra-like monster who wields a laser saber, a constricting whip, and can use a ball that can turn into a claw. He preceded to carry out the ceremony while his younger siblings battled J. He eventually took on Kamen Rider J himself to keep the sacrifice going, until Berry came to his aid in vain. But with Kana now in the egg chamber and Berry knocked out, Garai absorbed the surround mist to assume his true form. Garai was even stronger in this form when Kamen Rider J impaled a sharp object in him. Garai used his ball attack on him. When Kamen Rider J got free from it, he used the Rider Kick to knock Garai unto the alter, fatally wounding him.
