if you could own one pokémon of your favorite type

My choice would be Dragonite as it is my favorite pokemon. Another will be Infernape. It is a tough choice.

Why don't we have any fluffy Ice kitties? T_T

There's a part of me that wants to say Frosmoth since I really like moths, but I also have a hard time picturing myself with Ice-types whose bodies are made of ice/snow IRL. That said, maybe Sneasel? I really enjoy its aesthetic and, although it's mostly based on a weasel, it also has cat-like qualities (its Steam Siege card references cats in its attack Nyan Roll, or Cat Purr in Japanese). (IIRC, Weavile even made it into a cat-themed product line a few years ago.)

Then again, since Leafeon resembles a Siamese/Balinese cat, maybe Glaceon could be interpreted as a "blue-point" Siamese/Balinese...?

There are so many electric types I cherish, but my usual go to would be Pikachu.
Besides it's cuteness, I'm rather find with the moves it can use. I'm currently finding it difficult to put into words how much I cherish this electric mouse.

I would probably own a Galarian Weezing. I'd do whatever it takes to keep the environment clean.

The Bulbasaur-line for sure!

My favorite type is fire and fighting. So the easiest pick would be infernape. I love infernape so much.

Very complicated. Since I'm going with the saver favorite type, I would own a Normal-type that's small like a Zigzagoon, an Eevee, or a Minccino. I am preferring a Minccino on this one.
