We haven't even finished the first mission yet (actually, the 0th Mission). Having Bergen catch a Nidoran now or in the immediate future would be tantamount to just giving him it for free at character creation.

I don't plan on sidequests being availible until after the 3rd Mission Round, but you can still try to catch any Pokémon you see in Missions (though they may be taken away by Nurse Joy or Officer Jenny for research purposes)
