The first Pokémon I caught was a Sandshrew! I named him Rush, after the shiny Sandshrew I recently obtained in my SoulSilver Shiny Badge Quest. I'm gonna make him the best Sandshrew around!
I got a Vulpix. I will use it until I find something cooler, because I saw a Pikachu and a Squirtle before I could buy Pokeballs.
My first was Charmander, it was supposed to be Blaze but somehow ended up as Cinder (and yes, I have been documenting all of this in a bug report)
A Pidgey! Unfortunately, Pidgey was only my partner for like 0.2 seconds because I found a Vulpix directly after XD
I went to bed early so I wasnt around when this started. I just caught Vulpix as my first and a Raticate just now on this page.
I just spend a lot of money on pokeballs to get this party started and there he was, a Nidoran Male. That's a good first catch if you ask me.
