So the first time I did this I actually misread the OP. I read "Generate 1 Pokemon" as "Generation 1 Pokemon", so I made the generator only select those. I was wondering whether others in the thread didn't read the OP when Pokemon of all gens were being posted, but I'm actually the one who read it wrong.
Doing it again, I got Seviper. I guess I try to not be anyplace where there's a Zangoose.
