Wow, I expected to Nidoking to be slightly more popular, but not by as wide of a margin as that!
I myself voted for Nidoking as well, seeing as I don't worry about defensive stats as much as I do the offensive ones in battle. While I actually like Nidoran-F and Nidorina better, something about Nidoking's design really catches my eye, especially how well the purple color looks on it.
Remember, even though this week of voting is over, you can still continue to post in this thread even if it's been destickied! Look out for our next POTW, as that should be up very shortly!
