You can remove one Pokémon (or evolutionary line) from the Pokédex. Which do you choose?

I mean, they've never once in their life added a beaver pokemon and never will, so no need to remove a hypothetical line known as a "bidoof" line. Seen so many people trying to gaslight me into thinking that isn't some shitty line created by some of the same people who made those shitty early pomemon fan games with horrible fakemon that people have been putting into games as a meme.
Still waiting for an official first beaver based pokemon line. Hell, I'd even settle for my dumb idea of essentially a ghost water type beaver where the bottom half of the body is water, the tail is covered in a water shell, and the top half is a rotting dead beaver carcass.
- Shame, sounds like a great HM slave.

Pikachu (the Pokémon, not the evolutive line).
- I don't personally have anything against Pikachu as a Pokémon, but oh god once I opened a Falinks video for kids just because I like Falinks and was curious, and like… Pikachu was shoehorned into the Falinks video and I was displeased. I can see how people might dislike Pikachu for overexposure. Is that your reason, or is it something else?
  
  The oeverexposure is a big factor yes (Pikachu and Charizard are pretty much the official whores of the franchise). Gets more variants than Charizard, and gets variants solely so that it can be shoehorned in context where there's no need for it, such as flying battles. Doesn't help that originally Pikachu was more rotund but in the later seasons of the anime and since around G5 in the games they gave it anime hero body proportions, which also sucks.
  Haven't written any Pikachu in my works so far because why would I, I hate it. But if I ever need to have some bit NPC be outright demolished and mauled in a fight, Pikachu is among the top candidates.

I completely forgot about my dislike for Meowth until I saw a picture with Meowth

Rhyperior because it’s design is woeful. It ruins the whole line.
Replacing it with a design that isn’t so ugly would be great but I would settle for deleting it.

The elemental monkeys (first stage specifically) always annoyed me for no rational reason at all, immediate Pokémon I think of when I think of "least favorite". But that's three Pokémon, so I have to pick something else.
Really not a fan of Gothita. Or the entire line. Pokémon that evoke more human-like designs usually land on my disliked list pretty quickly. Just a personal dislike, no idea where it comes from.

Incineroar usage rate in tourmanets is way to big, let's mess that up and removing the Incineroar line.

I was going to say something like stunfisk but I feel like it would be more on-brand to say Seviper for no particular reason.
- Username checks out.

The entire Klinklang line.
✔️ Stupid, lazy poké-object design
✔️ 3 stage evolution that starts at level 38
✔️ Best learned moves don't get STAB
✔️ Ability useless without a complimentary doubles partner

Flabebe, Floette, Florges.
The most annoyed I ever was with this last gen was to be running through just about anywhere and accidentally start a battle because of these. Florges is an innocent bystander here catching strays.
