Here are all the canon heights of all the starter Pokemon (excluding the latest 2 gens)

Damn I did not expect my boi Feraligatr to be so tall
That's not a ten year old trainer either, that's Red as an adult (Him and Blue turn up in the Sun and Moon post game) so that's how tall they are compared to an adult dude.
I also just realised that Feraligatr is just the words feral and alligator smooshed together. Lol. Based.
I expected Blastoise to be bigger. He's Gamera coded after all, he should be taller!
A lot of numbers in Pokemon are super made up and weird. i.e. half the pokedex entries for fire pokemon talking about how they somehow contain the heat level of the fucking sun.
