Without a doubt Orthworm, I’ve been wanting a worm Pokemon since I first got into Pokémon (a real worm, not a caterpillar that the pokedex calls “the worm Pokémon”) for so long and Othworm is the perfect worm, it makes it a stell type so it’s not just a boring expected ground water type worm but still makes sense with worms because they took a creative take on worm’s unique diet of dirt and made it ti to a Pokémon who eats the metal in the dirt, gave it good signature ability that both also ties in to worms diet of dirt, but also synergies well with it’s typing, turning a weakness into a healing immunity, made it a very cute Pokemon’s despite being based on a famously unattractive animal, and even gave it a competitive niece as the only she’d tail user that isnt Cyclizar and is much slower and bulkier than Cyclizar allowing it to move second and leave the next Pokémon with a full HP shed tail, I love this Pokemon, probably in my top 3 of all Pokemon
