I'll be naming him Carlo. He's Giovanni's son and I think an Italian name would fit him nicely.
Mauro and Stefano are names I considered as well at some point.
Argento is not an option for me because it's not really a name for a person.
Probably Silver or Archie, because that's how I named my rival in silver too.
In RBY my rival was Gary and I was Ash.
In FRLG my rival was Gary and I was Josh.
In DPPt my rival was Jake and I was Josh.
Going by what I did in GSC, though...
My rival will be ASS BAG and I will be Josh.
dude ill stick with whi i usally go with titus
I've always used the name Reiji but I might go with something different now that there's a character named Reiji in the anime.
I'm naming him Vick.
I'm calling him Shinji in JP HG. Not sure about US SS. I may just go with Paul or Silver, but part of me wants to call him Heart.
