I'm naming my character Seb. Even though I'm a girl, I'm not fond of female sprite. Besides, it's a throwback to my days in Silver and Yellow where you had to be male.
I usually name my rival as a reference to books/movies/video games/etc., but I'm thinking of something else. I was thinking of giving him a name with a meaning that is similar to Giovanni (well, it's still a reference.. oh well). His name is a form of the name John... I'm thinking... Shawn?
I'm waiting for the English version, but I'm planning on nicknaming my entire team. Most of my names are references to various... things, but the references match the Pokemon... like, I had a Wigglytuff named Elle (from Legally Blonde). If it's not a reference, then it's a name that's kind of similar to the Pokemon's actual name. (Examples from past teams are: Raphael the Starraptor, Nona the Nidoqueen, Vivian the Gardevoir, Oliver the Zangoose... you get the point. Yes, I think way too much on names.)
