This is gonna take a while...
*brings up my list of all Pkmn in existance*
Firstly, some of the weird, creepy ones they seemed to "try" in Gen. 1, like Mr. Mime and Jynx... They freak me out... Are they even Pokémon, or are they humans classed so by racists? O_o
Next up, ehm, Snubbul and Granbull, Idk why, but they're really annoying... To look at. Sorry...
Then Pikachu. I don't know why, it's just that I think there are so many out there, knowing virtually nothing about Pkmn, getting the feeling from Pikachu in the anime and such... It's just... Sickening.
Then, oh, then those annoying good-for-nothing new evolutions...
Magnezone, Probopass, Lickilicky, Tangela's evo... whatever it was called, Rhyperior... Excuse me, but WHAT good did they do again?
I mean, Lickitung > Lickilicky... Is that even an improvement, Lickitung looks hecka better, as a sarting point...
And then, randoms! Grumpig bothers me, the gen4 cat family (I don't remember their names, Pur(e)ugly and whatever). Then Bibarel. I hate it. I actually use one as HM slave, in Platinum, but I make sure it doesn't have a very good time... >:3
