'Monstrous Rockasaurs'
Gobots Packaging '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 Terra-Roc! This winged menace soars through the air spreading fear and terror with his piercing cries warning everyone to 'Look out below!'
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 as of 2026 have not been sighted as released in Australia for Bandai's Machine Men Rock Lords distribution.

* Unlike previous EU Rock Lords packaging that showed, 'Gobots, A Robo Machine Product' packaging for Jewel Lords, (Action) Shock Rocks and Rockasaurs displayed only the Gobots branding.
** The grey Terra-Rock bootleg was purchased by Charles Ross from a seller in Indonesia. While this isn't a confirmation of original country of origin, a wide range of unofficial, prominent 80's toy line bootlegs were sold in Indonesia, often in different colours. It's highly likely this item was originally on shelves in Indonesia.
