Furio was the first villain introduced in Power Rangers: Lost Galaxy.
Furio (whose name is based on a term "Furious", hence his frowny face) is Scorpius ' general who led the brutal attack on the planet Mirinoi, seeking to gain the powers of the Quasar Sabers. Not amongst those chosen however, Furio couldn’t pull the saber from the stone, just like numerous warriors before him. He was confronted by six warriors (Mike, Leo, Maya, Kendrix, Damon and Kai) who battled his army of Stingwingers to protect the people. It was in this awesome battle, five of the six warriors than pull the legendary Quasar Sabers from the rock. Enraged, Furio sought to destroy everyone in Mirinoi by turning Maya's people and every other living thing in the area to stone. He pursued the warriors and managed to create a crevice in the jungle like planet, which tragically sealed Mike inside. Furio witnessed the warriors transform into Power Rangers and was no match against their energy. He left the planet and reported to his superior that he was going to retrieve the sabers for him. His next encounter with the rangers would take place on Terra Venture , where he attacked Leo but left abruptly. With Scorpius growing impatient with him, Furio assigned several monsters to snatch the sabers. When Horn succeeded, Furio ordered him to destroy the weapons, having been commaded by Scorpius to do so. He then allied with Scorpius’ daughter, the adventure starved Trakeena, and sought to gain the Lights of Orion, yet another ancient source of power. In a devious plot to use Leo for the Lights, Furio and Trakeena managed to trick Leo into believing that his brother had returned. When this plan failed, Scorpius almost destroyed him, having grown tired of his constant failures. Desperate to prove his worth, he finally stumbles on what he believes are the Lights of Orion. Before he can retrieve it to his master however, he’s interrupted by Leo once more. The two engage in battle and Furio, at his last straw, commits suicide by exploding himself and Leo, in a fruitless attempt to destroy his enemy because Leo is saved by Magna Defender.
He was one of the most loyal and sinister generals of Scorpius, having turned all the inhabitants of Mirinoi into stone. As the first major threat to Terra Venture, Furio often proved to be Leo's equal in swordfight; thus, his ruthlessness was instrumental in the maturity of the Red Galaxy Ranger.
