Heh, I rarely nickname my pokemon, except for HG/SS, and my latest playthrough of Platnium.
Here is the names I give my pokemon.
Starter: Steven (After the 3rd Gen champ.)
Golbat: Andrew (RP Character)
Bronzor (Is that it?): Christopher (First RP Character)
Eevee: Either Elisa or Kyle, whether it is a boy or girl (RP Characters)
Lucario: Either Esuine or Corosa (RPed as Esuine once, and Corosa is an RP character.)
Giratina: Satan (In my stories, Giratina is the devil, why not reflect that in my game file?)
That's my team for Platinum.
And if Chikorita is female, then I'll be naming her Flora, but I don't have any more specific names for anyone.
