What do you name your rival?

Called him SZ, it stands for Shocking Zapper but SZ just sounds better. :p It was based on a cheesy nickname me and my other friends gave to this guy we knew back then because he was in track and he could run fast as HELL, thus the lightning based name. I gave it to my rival cuz of how his hair/style looks.

I call myself Staryu, so we have a little Water/Electric rivalry going on!
