RE: What Is Your Most Disliked Pokemon?
There really aren't many Pokémon I dislike at all. There are only two that I actively despise, though.
My second least favourite I shall keep undisclosed, because it's love by so many people I might get burned at the stake.
My least favourite, however, is Togekiss.
Back in the days of Gold and Silver I always used to have the Togepi you hatch on my team (I reset the game A LOT back then), train it up to level 7, and just enjoy the lulz every now and again with Metronome. It was always a pain to evolve, too, especially back in those days, so I would just keep it in my party in the hopes of that raising its happiness. Only, on one run through of Gold, I actually used it often enough for it to evolve into Togetic and loved it a lot. It was adorable, and actually its stats weren't that bad. Certainly one of my favourites considering it was a trophy of having to go through raising the happiness of a Pokémon with little to no damaging moves.
When Diamond and Pearl came around, I was... surprised GF was willing to take the risk of adding SO many evolutions to old Pokémon. The worst of course was Togekiss. Not only do I despise its design (it looks like a cloud with eyes, they could have done SO much better), but also Togetic - once an adorable trophy of the suffering you went through trying to evolve it - is now all but forgotten and useless. Evolving a Togetic instantly will grant it an amazing moveset with Sky Attack, Aura Sphere and Extremespeed, so there is no need for Togetic to even exist any more in competitive terms, besides a sort of okay Special tank w/ Eviolite (and the only thing that makes it better than Chansey in that regard is that it can dodge Earthquake).
I short, Togekiss has a god-awful design and completely erases one of my favourite Pokémon from existence. I would have been okay with a Togetic evolution - excited even. But because of these reasons, it's shot itself to my no. 1 least favourite Pokémon. Togekiss is the only Pokémon ever which I would be happy if it was erased from existence - I literally can't say that about any other Pokémon. Great job
