These action-figures are a spin-off from Bandai’s and Tonka’s successful GoBots line of the mid-1980s. In 1986, specifically, there was an animated feature film called GoBots: Battle of the Rock Lords (1986) and it involved the GoBot Guardians protecting “powerful living rocks” from the likes of Cy-Kill and the leader of the evil rocklords, named Magmar (and voiced by Telly Savalas). Margot Kidder voiced the Rock Lord queen, Solitaire, and Roddy McDowall played Nuggit, the sort of R2D2 of this particular franchise.
Now, unlike Transformers or GoBots, these Rocklords don’t actually transform into vehicles…they transform into…fucking rocks.
What seems indeterminate to me is what exactly these rock lords are when they aren’t rocks. Are they robots? Biological organisms? WTF?!?
