Lol. I had ridiculous ones for my starters in all the games- kinda stopped with the DS games, just because. I had like Gigasaur the Venusaur, Pulverizer (yeah, I know) the Swampert, and Kakamber (yeah, I don't know) the Typhlosion. Actually come to think of it I had a fairly recent Platinum file where I nicknamed them. Kinguin the Empoleon and so on :D
Can't beat seed bby though ;) I'll undoubtedly annoy you to give me seed bbyish nicknames, lol.
