I’m not sure what is considered overrated and underrated pokemon but my two favorites are Feraligatr and Saxsquatch-squatches-shirt. Feraligatr because whenever I played gen II I never really felt like the other starters were all that great. Maybe I just sucked. But when I tried playing through them with a different starter they just felt really weak while I would curb stomp with Feraligatr. Scyther cuz when I was a little kid he had giant blades on his arms and I thought he looked dope.

Best Saxsquatch-squatches-shirt
Favourite overrated has to be Espeon, when I played Platinum my brother said Eevee could “evolve lots” not “into lots of different things” and back then I was 9 so all I cared about was evolving Pokémon and Saxsquatch-squatches-shirt. I couldn’t surpass Cyrus as my team was a couple of level 30-36 mons and one Lv 64 Espeon. That story always makes me chuckle.
