GoBots: Rock Lords is a spin-off toy line to the GoBots from Tonka in 1986 after the movie GoBots: Battle of the Rock Lords. They are transforming rocks that came with weapons such as axes, guns and swords. There were vehicles for the Rock Lords to drive in battle. The Rock Lords were imported from Bandai's Machine Robo "Ganseki Chōjin" sub-line. Like other transforming toys, there were "good guys" (led by Boulder) and "bad guys" (led by Magmar). The tagline associated with these toys was "Powerful living rocks!". Rock Lords was not a successful toy line. Transformers was getting the better sales, but Rock Lords was able to last for three series. There were unreleased Rock Lords toys such as the Stone Head playset and Crackpot in meteorite colors. Toyline Good Rock Lords Boulder (Japan: Battle Rock) Rock Type: Tungsten Bio: "Brave and wise with an awesome physique, Boulder leads the defense of Quartex against Magmar's villainous plots. Boulder has rallied the remaining free kingdoms of the planet under his leadership. His fiery temper strikes fear into friend and foe alike. In the heart of the battle, he scatters enemies with stungun blasts and zaps them with his Power Sword." Nuggit (Japan: Mecha Rock) Rock Type: Gold Bio: "Though he's a robot, Nuggit is worth his weight in gold! He's smaller than the other rock warriors but brave and bold beyond his size. Nuggit is very proud of his shiny finish. Nuggit's Tri-Gun does triple duty: the top barrel hypnotizes; the second barrel paralyzes; the third barrel revives the unlucky victim for questioning." Granite (Japan: Guts Rock) Rock Type: Granite Bio: "A happy-go-lucky rock with a ready laugh, Granite is truly a "gentle giant". But put him in the thick of the fight and he's one of the most fearsome combatants on the battlefield. Despite its ordinary appearance, the T-Gun's shiny bullets will pierce anything and that's enough to send any evil rock running for cover!" Marbles (Japan: Mask Rock) Rock Type: Cristobalite In the movie he has psychic powers. Crackpot (Japan: Cross Rock) Rock Type: Azurite Bio: "Crackpot's name describes his personality-slightly goofy. The other warriors give him a hard time about his crazy notions but Crackpot can think of good ideas that save them from a jam. His magnetic pulse ray "attracts" bad rocks and turns them into magnetic heaps!" Pulver Eyes (Japan: Sand Rock) Rock Type: Dolomite
