I named mine Blue the first time I played Blue.
And I named him "douche" in another game. See the "Supereffective" comic on VGCats, it provides a bit of humor regarding this.

LOL XDDD That's hilarious <3 I also remember when I was like 10 "Why wouldn't he remember his own grandson's name? Why'd he expect someone not related to him to recall him? Is he that senile?"
I know many who believed the rival's name to be ASH, if they played Blue. Since that was the counter choice to Red's GARY - and then got PO'd when seeing the anime. I still have friends today who say the anime is complete bullsh*t because of this xD
