Heheheh.
Just to clarify a lil…
Transformers more or less runs on the idea that if it’s officially-licensed, “everything is canon”, no matter how batshit. But just because everything is canon, that doesn’t mean it’s all “one story” that’s supposed to make any goddamn internal sense where everything lines up.
It’s not Hasbro’s goal to make everything matchy-matchy; it’s to tell the best stories we can, and if we can all squint and go ‘yeah, they connect,’ then we’re happy. Most people aren’t engaged in every aspect of what we do. — Aaron Archer[1]
Everything DID happen. Somewhere. Sometime. And in lots and lots of realities, it didn’t. Lots of alternate universes and timeline splinters (and re-merges). Quantum is heavily involved. The TF multiverse (in-universe) is a Koosh ball of reality that folds in on itself while ever expanding outward. That “timey-wimey” ball the Who fans like, writ large.
It is canon that in the G1 cartoon universe, the Constructicons were built in a cave on Earth without Vector Sigma in 1984 (“Heavy Metal War”), yet were also on Cybertron four million years or so prior. Which of those is true in-universe at the time all depends on where you are as the observer. (And if some later official fiction then No-Prizes that inconsistency, then that too is true, at least for that universe fragment.)
Am I talking out my ass? Kinda. It is, after all, pseudo-scientific gobbledygook meant to put an in-universe spin on that sage advice “it’s just a show, I should really just relax”.
But it gives us a canonical universe where Megatron has fought Master Higgins, and I think we can all agree that this is awesome.
