'Monstrous Rockasaurs'
The Gobots packagaing lists Spike Stone as a Rockasaur, while the European Robo Machine box shows this creature is a type of Rockasaur called a 'Styracosaurus'.
Gobots Packaging 'Spike Stone and other Rockasaurs roam the land showing no favor to either good or evil rock warriors. Rockasaurs guard their territory jealously attacking all who are foolish enough to challenge their might! When Spike Stone changes from rock to beast, he becomes a menacing monster!
Robo Machine Packaging (shared text on both EU boxes) 'Among the hazards of the planet Quartex are Rockasaurs. Both good and evil Rock Lords must be on their guard when travelling in the wilderness. The large rock they stumble over might change into a Rockasaur!'
Rockasaurs were not sold with any accessories and were not released in Australia for Bandai's Machine Men distribution.
See main Rock Lords index page for more general details.
