Emolga AKA Annoying Stupid Flying Squirrel - I hate this thing and it pisses me off that Game Freak shoves it in every new region ever since Gen 5. I was glad that it wasn't added in the Galar dex initially, but then they had to ruin things by adding it in the Isle of Armor.
Basculin - Why does this thing get shoved into every new Pokedex without getting an evolution? At least Zubat, Tentacool, and Wingull evolve.
Greedent - Let me collect berries, damnit!
Umbreon - Most overrated Eeveelution, and my least favourite. It's annoying and not cute. Even worse, this thing has won the Dark type poll 5 years in a row. Other Dark types deserve a chance too!
Patrat and Watchog - Annoying, hideous Pokemon that don't deserve to exist.
