Hasbro's original plan for the Beast Wars was to have Optimus Prime, renamed Optimus Primal, and Megatron be reformatted versions of their 1980s selves. This was shown in the toy's Tech Specs, and in the comic packaged with the basic Optimus Primal/Megatron two-pack. Hasbro also wanted the "Mutant Heads" found on all of the deluxe sized first year toys as battle helmets, but Mainframe scrapped the idea as it would have required three animation models for each character instead of two. Another designed feature for the 1995/1996 toys was carried over from , transparent "light pipe" eyes. However, most toys had those parts cast in opaque plastic.
