Galarian Meowth and his evolution Perrserker. Namely due to the color scheme, the black coin, the orange cat-eyes, his berserk stance, how his claws turn into knives and his hearty laugh.
Also, Perrserker is actually pretty good. I've been using Perrserker in online double battles, and it's been causing a lot of trouble for opponents. Thanks to it holding an Assault Vest, it's quite hard to actually fully deplete its HP. Here's a battle I did where Perrserker got burned and STILL managed to defeat two of the opponent's Pokémon:
It's also amusing to me to see Perrserker's design be so similar to Galarian Meowth's, as opposed to Kantonian and Alolan Meowth, whose Persian forms are pretty different. People seem to underestimate Perrserker out of hand because all they see is "Bigger Meowth."
Galarian Corsola
It references the dying coral reef situation here in real life. I like how GF brought in our world's issues into the Pokemon universe to bring awareness while giving an old, ignored pokemon new life.
And besides, galarian corsola is pretty cute. It has some interesting details in Pokemon Camp
I voted for Galarian Corsola for the same reasons. I also didn't realize that its branches were ethereal until I got ahold of one and I noticed they were wiggling and waving.
Cursola is also quite interesting from a design standpoint too. It looks like the bigger varieties of coral, also bleached, but it's more of that ethereal stuff. Cursola is actually less massive than Corsola, as the only parts left are its core and the bottom part of its shell. It only looks big because the ectoplasm, which weighs nothing, is holding up its core. From a gameplay standpoint, Cursola is also interesting because it's centered around sacrificing itself to inflict various effects on the opponent. It, and Galarian Corsola, get moves like Destiny Bond, Grudge, Perish Song, and Curse. And because of its stats, you use Cursola completely differently depending on if you're facing a physical attacker or a special attacker.
