I recall Xanthe saying that she'd try to make one for Groudon, but...it seems that she's just been really busy lately.

I'd like to see more entries, too, at least for Groudon! Said Pokemon has a much more complicated design than Kyogre and it would be really cool to see more emtries for. Kinda like how Brettles' is, maybe you could go for something like a lava wyrm-like design? Or some kind of larval being. Of course its not up to me, just trying to throw out some ideas here!
