As I see the favorite pokemon thread going on, how about sharing what your most hated were, too?
Most hated pokemon for me before black/white? Probobly Tangrowth.
Bidoof. Enough said.
Generation 1: Bulbasaur(I tried raising it once and it was the worst choice I ever made on pokemon)
Generation 2: Delibird(I don’t like healing the enemy)
Generation 3: Feebas(Ever try finding one?)
Generation 4: Leafeon/Glaceon(3 eevee evolutions was enough, 5 was too much, 7 is ridiculous)
Overall: Bulbasaur(Only starter that I ever raised and ended up for HM’s only)
My most hated would be Missingno
Generation1: Zubat. That freakin’ bat never leaves me alone, no matter what cave I am in.
Generation2: Jumpluff. Never dealt with one, but it seems to be the worst one in the generation. Rarely ever talked about, in my opinion.
Generation3: Feebas. (same reason as Molten)
Generation4: Bidoof. There’s nothing really to him.
Generation5 (based on looks): Either Woobat or Dangoro.
There are several pokemon I hate, simply due to them being so overly used in competitive battling. Cresselia was probably number one in my eyes simply due to her immense defensive capabilities, and the fact that I never seemed to prepare for her appearance.
Grant it Garchomp and Suicine had their places in the blackest pit of my heart as well…
The main Pokemon I dislike are those that are overhyped in competitive battling - they’re talked up everywhere and never do anything productive. Electivire, Weavile, and Cresselia are the main culprits.
Wait, I’m on Chief Delphi, right?

nuff said.
I’m going to have to go with the electabuzz/magmar evolutions. I’ll always remember those two Pokemon as JUST electabuzz and magmar, with no evolutions. That’s the way I was raised, that’s the way it shall stay!
Also, the majority of the black/white pokemon are pretty dumb. But hey, that’s what I thought about D&P before I started playing it.
Pikachu Deffinetly I abhore that annoying little rodent.
My least favorite gen 1 Pokemon is probably Muk or Grimer. They are ugly, a pain to fight, and I never even got as far as to raise one.
I never played anything after gen 1 so I can’t comment on the newer ones.
Edit: I forgot about Ditto…
Everything after the original 151 Pokemon.
Freaking Zubat.
Level 57 Blaziken uses Slash against level 20 Zubat…and it’s NOT a one shot KO. Stupid Dark type.
Dark type? Zubat is Poison/Flying, a normal move like Slash should do normal damage.
As for my most hated pokemon, I would have to say Celebi, as it was a very disappointing legendary.
Any pokemon my friend battles me with that doodoo. He cheats 
Dido, it was useless unless you used it for breeding in gold and silver…
Blaziken is Fire/Fighting using a Normal attack against a Poison/Flying pokemon. Type advantage doesn’t even come into play.
The ones that aren’t released.
Everything after Gen II, especially evolutions for already established pokemon…although there are some sweet Gen V’s, like the grass/steel mace thing (more of a novelty than good)…also I think that the abilities added in Gen III were cool, but contests and pokeathalon are just STUPID BEYOND BELIEF!!!
i agree except arceus and lucario
