What's your least favorite Pokémon [of Each Type]?

[KorpiklaaniVodka]

K.

Bug = Genesect because it's so ugly with that look, and it reminds me of those buzzes from DKC3, bleh. Genosekto > Genesect by far. Annoying competitively (that Scarf set could smash any team in OU, hence why it was banned) and very strong even in Uberz
Dark = Absol. Overrated and it looks too bland, and it's not that good.
Dragon = Palkia. Its head. ITS HEAD. Wanna know what it looks like? I get how good it is competitively, but when your head looks like a male's private part, you have problems.
Electric = Thundurus. All three genies were poorly designed in their Incarnate forms, but Thundurus is probably the worst of them all, with an ugly name, ugly color, and an overpowered ability which ultimately send it to Ubers.
Fighting = Probably Breloom, but I don't hate it. Maybe because of how annoying it is.
Fire = Flareon or Volcarona. Flareon is so underpowered... plus it's an Eevee evo, and I never liked them. Volcarona... *cough* Quiver Dance *cough* 4x weak to SR *cough* 135 Special Attack *cough* horrible physical defense. Yes, Volcarona is in my opinion one of the most overrated OU Pokemon, and every one of its advantages are mitigated by a horrible weakness. It's great on paper, but it never worked for me.
Flying = Tornadus (-T) / Thundurus / Landorus. Lazy designs, basically they made one of the three and the other two are just recolors. Tornadus-T is creepy too.
Ground = Landorus. Uber + uber ugly.
Ghost = Dusclops. Lame design, lame cry, lame in competitive play even with the Eviolite. It might look better than Dusknoir, but if I managed to get 1950+ ACRE with Dusknoir, I don't think it is better than its evo.
Grass = Celebi / Ferrothorn. I don't hate them, I just like them less than the other grass-types. Although I have to give props to Ferrothorn for being so annoying.
Ice = Kyurem-White / Glaceon. Kyurem-W is overpowered and it doesn't look like a legendary Pokemon. It's the perfect example of an overdesigned thing. 170 Special Attack? STAB Draco Meteor? Choice Specs? No no. Glaceon is just dissapointing.
Normal = REGIGIGAS (aka Regigigigigigigigigigigigas. Impossible name to spell. Extremely annoying to obtain in-game. Extremely ugly (what is it supposed to be?). Useless in competitive play, even in NU. Need I say more?)
Psychic = Mr. Mime / Gardevoir (Mr. Mime looks soooooo creepy. Gardevoir is overrated and it sucks even in NU from my experience.)
Poison = Tentacool and Tentacruel.

*throws his DS at the wall*
And for the record, Tentacruel is even more annoying competitively, thanks to Rain Dish and its secondary Water typing.
Rock = Aggron. Overrated and too slow to be of any use.
Steel = JIRACHI.
The foe's Jirachi used Iron Head!
Your Pokemon flinched!

Water = There are many Water-types I hate.
a) Did I mention Tentacruel? I think I did.
b) Ludicolo. It looks horrible.
c) Piplup because of its annoying voice in the anime. I don't like Oshawott either because it's fugly, but it's not nearly as bad.
d) Did I mention Palkia?
e) Politoed because of Drizzle. When will Drizzle get banned, Smogon?
f) Keldeo because of being able to abuse Drizzle so well and because it looks like a MLP character.

[Arise]

I tried my best to narrow it down, but it was impossible for some of the types. I apologize in advance if I happen to insult a Pokemon someone likes. Remember that it's just my opinion and that I mean no disrespect towards anyone. >< Spoiler tag 'cause it's long.

Spoiler:

Bug: Pinsir, Shelmet
Both are downright ugly and have creepy mouths.
Dark: Drapion, Stunky/Skuntank
Drapion looks like a scorpion that fused with a jack-in-the-box, and it's ugly. Real skunks are adorable, whereas Stunky and Skuntank are hideous.
Dragon: Bagon/Shelgon/Salamence, Druddigon
Bagon reminds me too much of Yoshi. Shelgon is just...I don't know, I just don't like it. Salamence's wings are stupid as h***. Druddigon is just really ugly.
Electric: Stunfisk
I literally said to myself "What the h*** is that?!" when I encountered it for the first time. It's facial animation scares me (as does Palpitoad's).
Fairy: Swirlix
That derpy face, and that tail that looks...disturbing.
Fighting: Combusken, Hitmonlee, Hitmonchan, Throh, Sawk
I would have hated Combusken's design anyway, but ever since I read someone's opinion of what it looks like...cannot unsee. Hitmonchan, Throh, and Sawk look too human-like for my taste, and Throh and Sawk look like they should be part rock type. Hitmonlee's design is just too weird for me.
Fire: Chimchar, Combusken
Chimchar doesn't look right for a Pokemon, it looks more like a Sonic or Samba de Amigo character to me. Maybe it's the eyes. Also, it looks like it lit a fart on fire. See Fighting for Combusken.
Flying: Pelipper, Tropius
The shape of Pelipper's body, what is up with that? It looks like a flying axe. Tropius' "wings" are as stupid as Salamence's, not to mention the fact that bananas growing out of its neck just kind of grosses me out.
Ghost: Cofagrigus, Spiritomb
Both just seem like really lazy designs to me. And bad designs, at that.
Grass: Exeggcute/Exeggcutor, Tangela
Don't even get me started on Exeggcute and Exeggcutor. Someone really needs to explain to me how a bunch of rotting eggs turn into coconut heads on a walking palm tree. And even if they were unrelated, their designs are still terrible. Tangela's design is just stupid, especially the shoes. It reminds me of those old McDonald's mascots, the Fry Kids, which makes me hate it more (if you have no idea what I'm talking about, just google image search it). Plus, I've done most of my post-game training in SoulSilver at the base of Mt. Silver, and Tangela are everywhere.
Ground: Diglett/Dugtrio
Lamest designs after Grimer/Muk. How can NO ONE know what the rest of their bodies look like?! Don't they get released inside buildings, or ever have to get serious medical treatment from injuries? Just stupid.
Ice: Jynx
She and her clothes look way too human-like (and I don't care that she's the "Human Shape" Pokemon).
Normal: Happiny, Lickilicky, Patrat/Watchog, Smeargle
I hate Happiny's design, especially the bumps on her head. Lickilicky is just stupid. I was so disturbed when I saw the artwork for Patrat and Watchog for the first time - their eyes are disturbing, and Watchog just has a plain hideous design. Smeargle just bugs me.
Poison: Drapion, Garbodor, Stunky/Skuntank
See Dark for Drapion, Stunky, and Skuntank. Garbodor is self-explanatory.
Psychic: Exeggcute/Exeggcutor, Jynx, Mr. Mime
See Grass and Ice. (Mr. Mime is in the same boat as Jynx.)
Rock: Nosepass/Probobass
Some of the worst designs for a Pokemon, imo. Don't know what else to say.
Steel: Probopass
See above.
Water: Keldeo, Pelipper
Keldeo looks like an awful My Little Pony fan character. I particularly hate its nose. See Flying for Pelipper.

Woo, so nice to get that off my chest. XP
