In Cybertron, Optimus had a gorilla toy (redeco of the 10th anniversary toy), so that's counted... but the bat is conjectural if you take retconning into account or if you follow toy bios and ignore cartoon/comics.

However, if you go by just "Optimus" like you would "Megatron" as a name & homage, the Primal would count with Prime... as the point of the list would be the same as if you did up a Megatron list.
