Kamen Rider
Saboteguron was originally a commander of Shocker's Mexico branch responsible for destroying the Paras Dam and solidifying Shocker dominion of Mexico. After advancing Shocker's hold on Mexico to 99%, the Great Leader summoned him to go to Japan to deal with the Kamen Rider, who had become the top enemy of Shocker.

Saboteguron arrived in Japan in the disguise of an FBI Agent. After Kazuya Taki uncovered his true identity Saboteguron attempted to kill him. Saboteguron hatched a scheme to destroy Japan's Sakuma Dam with the "Flower of Mexico" bomb similar to how he destroyed the Paras Dam. He was destroyed as he was fighting Kamen Rider #2 when he crashed onto a rock while carrying several Flower of Mexico bombs.
