Optimus Prime; he who wasn't a Headmaster originally, who now has 2 new toys in 2016 which are both Titan Masters..

In all honesty though, I actually like this voyager a better than the Leader PM Optimus. PM Optimus seems rather fragile, while this seems more solid. Also, If you look at this one's robot mode from the front, it's hard to believe that it can turn into a cylincrical-shaped cargo plane. Even though it's an homage to G2 Laser Prime, the option to fold down the shoulder "towers" and push down the antennae makes a pretty definitive-looking classic G1 Prime.
