Was thinking about it and got way curious... From Dreamwaves MTMTE profile books: 1. Alpha Prime 2. Guardian Prime 3. Sentinel Prime 4. Optimus Prime 5. Rodimus Prime From AEC: 1. Vector Prime 2. Nemesis Prime And Don's Macromasters comic had a Maraudimus Prime (I don't know if that counts but its an awesome name) Am I forgetting any?
