This is really pointless, but I was wondering what everyone named their Rival in Heartgold/Soulsilver. Originally, I had Crystal version, and I always named him ??? since that's what he would tell me. This probably came to mind because I named my rival Kakuza (really Kakuza tou but there wasn't enough space). I think this is a very appropriate considering his history.
*Spoiler Warning* This information is found out during an event, so if you don't think you'll get to do it, you can read about the rival's past here.
And there's my story
Feel free to explain your names, if there is any particular reason.
