Been wanting to make a Mawile OC for a good while now! I also talked with a few friends about Pokemon OCs, & I wanted to see what I could do by limiting myself to only changing/adding physical features instead of putting on clothes or an accessory of some sort. Not that it'll stop me much on this character either, but I'll see. Not too much, but I did want to do something like this anyway!
Like Saphris, you can find this with a bit more detail(just text, really!) over at my InkBunny.
