Goldgoyle

Goldgoyle was Divatox's last and most powerful monster and the primary antagonist of the first part of the two-part season finale episode of Power Rangers Turbo, "Chase into Space". During his entire time on the show, he was a giant monster, and was nicknamed "The Most Destructive Monster in the Whole Universe."

He was indeed among the strongest monsters in the entire franchise due to his incredible firepower and his absurd durability, as he was easily able to best the Turbo and Rescue Megazords with absolutely no trouble, zords which were stated to be more powerful than the Zeo Zords which were stronger than all of the Dinozords, Thunderzords or Ninjazords.

Goldgoyle was hired from an outside source (presumably the United Alliance of Evil) as a final attempt to defeat the Turbo Rangers. He was first seen on the moon, where Divatox was highly impressed with this monster and sent him down as the final attempt to defeat the Turbo Power Rangers once and for all. He then appeared in front of them in a red and black robe before transforming into his true form, after he introduced himself to the Rangers and mocked them. They mocked him right back but he showed that he meant business by using his signature lightning breath to take the five of them down. The Rangers summoned the Rescue Megazord to battle this super monster. Initially, the Rescue Megazord was able to dodge Goldgoyle's attacks but when Goldgoyle ruined their blasters, they called on the Artillery Cannons, which had no effect whatsoever on Goldgoyle. He then tossed some energy of his own at the Rescue Megazord. T.J tried in desperation to self-destruct the Rescue Megazord, fleeing into the Turbozords in the process, which slowly walked over and held onto Goldgoyle, who was surprised at what was going on for a second, then after the explosion, he remained intact and taunted them.

The only option left was the Turbo Megazord which despite being weaker overall, could get in closer. The Turbo Megazord used a special variation of the Spinout, dodging Goldgoyle's mouth blasts, shooting itself through the monster, a finisher much more powerful than the original and even more potent than the Artillery Cannons. It did not finish off Goldgoyle, but it did a great amount of damage that the monster didn't let on to. He used what was left of the spinout energy and infused some of his own to create the biggest blast he could to hit the Turbo Megazord, which went down in three hits but wasn't destroyed. All that was left to do was fire the Turbo RAM at his mouth. The RAM normally would have been eaten with little to no effect on the monster's insides, but the Turbo Megazord drill spinout through his midsection weakened him enough inside that he was destroyed when the Turbo Rangers launched their Turbo R.A.M, in self-destruct mode, into Goldgoyle's mouth, causing both of them to explode, and thus, Goldgoyle is destroyed for good.

In spite of his death, Goldgoyle proved to be a posthumous success since Elgar and Rygog saw the Rangers teleport back to the Power Chamber so they brought down the entirety of Divatox's army on it, leading to its destruction and the events of Power Rangers in Space.
