I don't think we'll be able to name our rival. If we did I'd probably name it the opposite game (If I had Diamond, I'd name the rival Pearl and vice versa). I'm so original
I hope we can name our rival, it's a cool feature. If I had the game now, I would name his DANTE, as that's the name I used in Pokémon Red/Blue, but by the time the game is actually released in the UK, I will probably have decided upon a different name.
I'm usually boring and pick the standard name, like Gary, but occasionally I name the rival after my best friend/nemesis Tim. If it's female, I'll probably go with the standard.
If I give my protagonist a French name, I'm going to go with a good German name for my rival, either Hansel (male) or Heidi (female). If I opt for a Finnish protagonist, something Swedish will suit, maybe Jan (male) or...I can't think of a female Swedish name. :<
And I'll try to get back in the groove here. D: Yay make-up work.
