Hmm... Okay, this is really far-fetched, but is it because of Extremespeed's 100% accuracy?
I can EV train it but i wont be able to nickname it as i got the zubat in a previous saved file which has now been restarted. Is the standard set bat what you want?EV train that Zubat in atk and spd, and you've got them. Name it Eddie.
No relation to accuracy. Think more of the creature itself.
