Is there a pokemon evolution that you think “ruined” the evo line?

For me it’s Walrein. I hate Walrein. Spheal is a perfectly adorable boy, and Sealeo is a great and entirely acceptable evolution, which is where it should have stopped. WHY does it have to evolve into a weird clown-walrus thing 😭 Shoulda kept it as its own separate thing

Anyone else have one?
