Groudon is one of my favorite Ubers, but it's probably one of my least favorite things to draw, as I've learned. Way too much detail for my patience.
Anyways, this is Groudon resting after that battle in Ruby/Sapphire/Emerald.
Sorry about the tail, but Groudon's tail is very...inflexible. Can't put the tail behind the Pokemon, since it's sitting, and in front, it just looks awkward. And before you ask, I BS'ed the background. I originally wanted a blank background, but whatever. Lots of quick strokes of the mouse later, I got the lava done and the rocks and whatnot finished. Groudon lives in a volcano, right?
