If you could start with any non-legendary Pokémon (in its basic form, of course)...

[DoctorWhy]

I would likely go with Eevee as well

 

[ZxCv]

First instinct was Vulpix and I can dig that. Reasonably strong, not an ultra rare typing but rare enough. Cute too and easy to imagine carrying around Pikachu style.

 

[LavenderCase]

Too many Pokemon to choose from...I'm also inclined towards an Eevee or Vulpix.

 

[Ｄｉｓ]

I've always wanted to start with a Growlithe because of some story I thought up about some kid going on a journey with his pet

 

[Kharixi]

For an actual game, Eevee would be cool. For me, probably Ralts so I could get a Garde.

 

[King Robert]

Crobat's been my fave, so Zubat.

 

[Dapper Rowlett]

My favorite Pokemon is Greninja, but Froakie is a starter, so I think having Honedge as a starter would be cool Only thing is that it'd be weird for your starter to need an evolutionary stone, but whatever, it says any non legendary basic, so yeah.

 

[Arylett Charnoa]

As for me, I can already start with my favorite Pokemon too. (Braixen) there are far too many options though... hmm. I'll go with the usual Eevee though because my first actual pet that I take care of reminds me of Espeon and I love Psychic-types and felines. Although on that note, Espurr would be pretty awesome too. Female though.

 

[Lyrebird]

Grimer cause I can call it...

Spoiler

That or a Horsea would suffice.

 

[Bladeheart111x]

Kanto: Meowth, because of Pay Day (I know I'm greedy)
Johto: Spinarak, despite me having arachnophobia, because Ariados is one of my favorite Bug/Poison types (behind only Beedrill)
Hoenn: BAGON FTW!
Sinnoh: Starly, as Staraptor is the most OP Normal/Flying type fully evolved Com Mon IMO
Unova: JOLTIK, My fave Electric type from Unova
Kalos: Honedge, because it's A FREAKING SWORD!!!! And my favorite evolutionary line.
Kalos is my ideal choice, but Hoenn is the region that I first cleared, and Sinnoh is the home region of my OC, Shane Maxwell (More on him when I get better at writing fanfics.)

 

[Woyaojinkela]

Depends if you are allowing hidden ability or not. If hidden ability is allowed i might just go with torchic or froakie XD. Cuz they are strong when fully evolved and is not too hard to train. If no hidden ability then i guess i will just choose sneasel. I like weavile n_n. Sneasel is good even if not evolved. It's not too hard to evolve it unlike some pokemon you need to evolve it to like level 50 .-.

 

[techitisJ]

I did one of these with one of my run throughs of X. I traded a Meowth over to X and used it. I've also done a non Kalos starter with my Y run through (which i lost the cartridge for and I'm still upset over it) and instead traded a Cyndaquil over, but that is a starter so that doesn't count for this.

Shinx would be a fun one, and so would Litwick. Mareep of course, and Dewgong's my favorite Pokemon so I'll have to do a Seel one eventually

 

[Pika_pika42]

Pika pika chuuuuuu.

 

[ManUtd22]

Nidoran the girl one, or maybe zorua

 

[PkmnTrainerV]

I have some signature Pokemon, but the one which persists on all (except monotype ones) my teams is Raichu. Charizard and Typhlosion are next ones in the line.

EDIT: Wrong thread. I wanted to post on the signature Pokemon thread. I'd like to start with a Pikachu/Pichu which you can evolve all the way to Raichu.

 

[zvinko]

Snivy, so I can have my favorite- Serperior.

 

[SinnohEevee]

A female Eevee that I may give an Everstone or evolve into Sylveon or Espeon.

 

[NMLewis]

It'd have to be Spheal or Miltank. And Miltank's a bit of a cop out, since she's... already great. Spheal is actually pretty good as basic stages go, I feel. Meets the adorbz quota for a starter IMO, too.

 

[Deleted member 72389]

Either a Pikachu/Pichu or an Eevee.

 

[FroyoDragon]

Riolu all the way :> his evolution via friendship would also give me some degree of attachment to it beyond being my starter.

Besides Riolu; Gible and Togepi, too.
