You could try Sugata, he's a well known fictional (I think) Judoka from Japan. If you're looking to get a new texture set maybe you could match the name with them theme of your textures. Handlebar, MrSofty, Gravitard, Centurion, Kagemusha (Shadow Warrior), Deodorant, LoveHandles, Phlegm, Toylet, Pancakes, Sermon, Beelzebub...
Sorry, I haven't checked to see if these names are taken or not. Good luck finding a name!
