No it is not.
I don't care
how much of a Transformers fan you are. Learn common sense.
Optimus Prime is in the same exact boat as Goku, Shrek, and SpongeBob.
The only difference is that he isn't memetic in relation to Smash.
"B-b-but MUH SPLATOON"
But
nothing. It got a theme for a Splatfest
exclusive to North America.
When Squid Girl got actual gear for the Inklings to use.
SQUID GIRL FOR SMASH?!?
Or how about the fact that Nintendo owns (or owned; not sure if those rights expired or not) the rights for Hamtaro when it comes to video games?
HAMTARO FOR SMASH?!?
Hell, even
Popeye has more reason to be in Smash than any other character of non-gaming origin, yet no one seems to go POPEYE FOR SMASH?!?!
EDIT: I'm not saying you can't want Optimus Prime. Anybody can want whatever they want no matter
how ridiculous.
But don't act like he has reasonable odds just because you're biased for him.
