Anytime I'm asked this question, my automatic response is Bulbasaur
at least, when it comes to Grass Starters, it's my favorite! It's hard NOT to choose Bulbasaur whenever the chance arises. If we're talking Fire Starters, that honor goes to Litten
and lastly, out of all the Water Starters, I always gotta have my Sushi!
(it's the nickname I give Oshawott each and every time I use one on my team)
So naturally, in Legends Arceus, I picked Oshawott. In my most recent playthrough of Scarlet, I used an Oshawott, and in my current run of Pokémon Super Mystery Dungeon? That's right, it's Oshawott. I really can't help it. It's just so adorable!! It's such a perfect design, just look at that round head, those stubby paws, the way it walks and its adorable smile, and that white and blue color scheme is just the best. And the way it sleeps, using its Scalchop like a nice, comfy pillow <3<3<3
I'm one of the very few that enjoys using Chikorita, and every now and then I use Cyndaquil, too, but for some reason I never want to use Totodile! Even though I actually like it and its evolutions.
I'm more of a Treecko gal, too. In general, I mostly lean towards Grass Starters, with my least favorite being Sprigatito. My second favorite Fire Starter? It has to be Cyndaquil, with Fuecoco right behind it
