5th Gen When did you get your second Pokemon you actually kept?(B&W)

Well I caught a Lillipup, but he didn't have any useful typing later in-game, so around the 2nd gym I dropped him. Then I got a Pidove, which I kept till the Ice gym, but ditched for a Beartic...so I think my first pokemon I have kept on my team so far would be my Sandile, now a Krookodile, named Caiman.

The first Pokemon I caught after getting my Oshawott that I still have today was my Drilbur that I caught from the first cave you encounter. I spent a good few minutes trying to encounter him, and I still have him now (Caught him at level 12, he's now a level 56 Excadrill).

He's a brilliant Pokemon for where you can get him, I actually rate Drilbur/Excadrill as one of the best new generation Pokemon in Black/White. I'd recommend going through the extra effort to get one if you haven't already. :)

Pinwheel Forest is where I got my Venipede and I already had my Pignite. I then got a Plume fossil in the Desert Resort if that counts.

My second pokemon was a Woobat, caught in that first cave next to the day care. It is a Swoobat now, and is about to be replaced with Frillish, since I need something good against Psychic, Ghost, and Fire.

I think it was a Whimsicott, although I didn't actually keep it all the way through the game. I traded a petlil for it.

The first pokemon that I kept in my party was Scraggy, who replaced Timburr. On the subject of replacing pokemon, I actually trained like 3 guys who never made it to the end of the game. Not to mention I didn't have a full party until the 8th gym.

The second Pokèmon i kept would have to be my awesome Throh. He's been in my team for quite some time and I'm not planning on getting rid of him even if he is weak against Flying and Psychic. He is still a useful part of my team.

well shoot....the only pokemon that seem like its guna be in my final team along side my Pignite is Cotonee and Scraggy.....because i really dont like wat blitzle turns into and when tympole evolved i got very upset at it......so rite now i got that water/ rock turtle thing and a solosis my lil brother gave me.......so yea not sure wats the future of my team is guna look like..

I'm thinking that semisage/grasswott is staying from me. Same thing for dewott/ninjawott.

The first pokemon I kept was the Pansage you get in the Dreamyard. Though I did swap out later I kept it for the majority of the main story.

I kept pidove (which is now a female unfezant) and I kept blitzle which is a zebstrika now, and I kept sewaddle which is a leavanny now. I also kept scraggy and until I swapped it for beartic, I had a timburr, which evolved to a gurrdor.

I traded myself a Pawnaird as soon as I started the game.
He's sturdy, to stay the least. Great defense and very decent offense. He was an absolute powerhouse through the beginning, although he's taken on a sort of "grand master" role recently. He doesn't need as much training as his teammates, so he doesn't see much battle and only occasionally steps in to save the day.

Tympole was my first caught Pokemon in Black and I kept it till after the e4, its now a 77 Seismitoad - 3rd Pokemon that I caught was a Pidove which I kept till after the e4, it's now a lv 66 Unfezant.

The first pokemon i kept was Pidove

First catch. :)
T'was my Lillipup.

Either my Pidove, my Munna or my Pansage. I don't quite remember, but it's probably the Pansage... I got them all in or around the Dreamyard as soon as I could get to it.

I'm currently on my second playthrough of White, and the second Pokemon I got was Panpour, to compliment my Snivy. Right now, it's evolved into Simipour, and it can dish out some serious damage with Scald. ;D
