Verno: No noticeable class/caste division in Japanese continuity.

drahsrebu: The Obliterators were part of the very last batch of Transformers released under "Transformers" (G1), and as such were later repackaged as G2 Transformers. As such, they are commonly referred to by fans as "G1.5" because the toys are identical, and the only way you can tell if it's G1 or G2 is by the packaging that it came in. I only ever got Colossus/Clench -- never got Pyro. I quite like Clench... Pyro suffers from brittle gold plastic syndrome, whereas Clench doesn't (to this day my Clench remains in good nick! ). As for aftermarket value... I did see one at a collectors fair sell for $50, but that was years ago. No idea how much they'd sell for now I'm afraid.
