2. Primus
Hasbro/TakaraPlanet-Transformer-God Primus has been a part of the Transformers story since the Marvel comics, but hes only made a handful of onscreen appearances, far less than that other planet dude. While its unlikely that such a character could exist in the live-action films in terms of story (the Unicron/Primus origin story has been retconned out of that universe, sort of), just think of how hed look! But of course, if the character redesigns of the live-action films are anything to go by, hell look a right mess. Plus, creating such a character would perhaps burn too much of a hole in the film-makers wallets. But we chouldnt give up hope. Primus is, after all, the creator of the Transformers, even though the live-action films say that the Transformers originated from the Allspark. But we can still dream, cant we?
