He's a new character that's been floating around in my head for a while. To cut it down into the shortest of summaries, his story is about a Yokozuna, three time grand champion, that offends a witch. The witch is so offended that she puts a curse on the sumo... if he wrestles again he'll turn into the animal he enjoys to eat the most. Most of the story i have in mind is of him living out in the countryside.
I haven't decided which animal yet... it would have to be one that could store a lot of fat.
