I started a Pokemon based DnD game and while we were still making our characters, I started to draw a Garbodor. It started honest enough, then I added my typical style of eyes instead of the dots that a Garbodor normally has. It looked so cute that I decided to make a chibi. After making to chibi, I kept going and made it into a sailor scout.
