I am a huge piplup lover, I adore the little penguin and as a little girl i would snuggle with the talking plushie constantly, pretending I was a Pokémon trainer with it, just loved that Pokémon!
I know snakes are my favourite and my heart is towards Snivy, Cyndaquil has to be my favourite starter. It was my very first starter and truly captures the true essence of the Johto region. Cyndaquil, also being a Fire Type, is a complete win! I am very fond of how Cyndaquil acts as Gold's Pokémon in the manga. Definitely my favourite!
Fennekin. 6th gen has a lot of faults but the starter Pokémon weren't one of them. I adore the little witchy fox.
I have to go with the old classic Charmander. Charmander was technically my first Pokémon. It's a pretty typical kind of answer cause yay Charizard but well why wouldn't it be, it's an awesome dragon thing and one of the best designs in first Gen. Having two Megas (the Dragon one is nice so everyone finally was contented about "it looks like a dragon but is not dragon type why") makes things pretty awesome. I like Y better myself. Yep, good old Charmander.
How dare you make me choose between all my babies!!! But, because of fond memories and Pokémon Golder... I choose Cyndaquil. It helped me through everything in original Gold and HeartGold, and was my first starter and by extension Pokémon.
Gotta give this to the first starter I ever picked; Totodile back in the good ol' days of Pokémon Crystal. I'm kinda surprised though that Feraligatr is still useful for battles, too, even though yeah there's probably stronger starters out there. Yay for Sheer Force. <3 I do have a soft spot for Rowlet, too. I wanna get like a mini figurine of it if I can.
Mudkip, because you know...memes But seriously, I choose Mudkip because when it evolves, it gains the Ground type so it's only weak to one type now: Grass.
Litten is adorable...it has become my favorite starter, too bad I hate Incineroar's design and how it's not a cute lion beast
Treecko is my favorite, but Litten and Snivy are close behind as the greats in my book, with Piplup right behind.
It was difficult to pick one but I love Rowlet. I was never very much of a grass starter fan but for some reason I really love Rowlett and seemed to have loved training and using this starter the most out of all of them.
It's such a tough choice. I love Bulbasaur, Chikorita, and Totodile so much... they're extremely adorable and I always find it hard to evolve them (though I love Ivysaur also). I'm a big fan of the gen II starters in general and must have used all three at least a dozen times over by now. My all time favorite is Chespin though. He's very unpopular it seems like, but when I saw him in the anime I fell in love immediately. Clemont's Chespin is one of the best things to come out of the series. Run my mischievous cutie!! (Brownie points to Squirtle and Fennekin also. <3)
I'm really fond of Torchic and its whole evolution line. Fire types are probably my favorite, and Blaziken's right up there at the top. Points to Snivy, Chicorita, and Cyndaquil, though.
I really like Turtwig, Chespin and Rowlet, but my all time fave is Litten. I've always been a cat person, and Litten is life. I don't like Incineroar's design, but Torracat gets two paws up!
In terms of base form, Tepig is my favorite, but its evolutions were a letdown. As far as the entire evolution line, I like pretty much all of them too much to decide! (Except Popplio and Chikorita. I don't like them much.)
