Shuckle. Don't know why, but I ****ing loved that thing. It doesn't even look menacing, but for some reason I thought it was amazing. And Pidgeot....I'm still sad he's so bad. Oh, Feraligatr and Pikachu too. What can I say, they were my starters in the first two games I ever played.
I actually DID always think Gengar, Starmie, Tyranitar, Gyarados, Snorlax. and Alakazam were really good. I suppose some of them had their weaker moments in Pokemon history, but I was sort of on the money with those guys.
On the flip side, I used to assume everything that didn't evolve sucked (non-legend, cause as a little kid those guys were all UBER). It still works with some of them, particularly the gimmicky ones, but it's obviously a VERY stupid rule to abide by. Skarmory was my wake-up call to give these guys a chance.
I summoned a baby to attract a lion. It didn't seem to work, so I tried a delicious baby. Regular baby ATE delicious baby. Horror....horror.~Gameplayingperson
To be fair, there are a lot of pokemon in lower tiers that are pretty decent stat-wise and/or movepool-wise, but are either outclassed by a pokemon that does it better, ruined by weather or entry hazards, or just don't have access to those one or two moves that would make them much more viable.
Case in point: Swellow with guts is a fan-freaking-tasticly powerful physical attacker that out-speeds and out-powers MANY pokemon. However, its movepool lacks coverage and it's weak to stealth rock, so it goes in the never-used tier. Is it a bad pokemon? Hellll no. It just lacks in pretty much one key area that holds it back.
I can't really think of a specific pokemon that was in a lower tier than I thought it would be at the moment, however I recently discovered that my favorite pokemon Sandslash was actually much more viable than I thought. Huzzah!
