Are you saying that Optimus isn't humble enough to lend his power to his friends for their benefit? If others have combined with Optimus before to power him up, shouldn't it be only common courtesy for Optimus to take a turn at powering up someone else? He's a team player.
Of course Optimus would gladly act as a belt and backpack for his comrades, he's just that kind of prime, by why would TakaraTomy even ask such a thing of him? And you literally can't tell he's even involved, he could have at least been visible from the front!
I know I shouldn't be saying this for several reasons, but hey, I'm going to:
In the Japanese Masterforce cartoon, the Powermaster Optimus Prime design was repurposed into a new character named Ginrai. Same overall archtype though, he even had his own combination gimmick in the shape of Godbomber. In the Victory series Ginrai was killed off and turned into Victory Leo, who for all purposes was a power-up for the new leader, Star Saber.
In short, from mighty leader with magic mushrooms, to a mere magic mushroom for a new leader. It has been done before folks. P.S. Sabrblade, I already know about the human + transtector thing and the transtectors being given proper life, so don't you dare.
