Here is one on Lvl 12 with Ember, Smokescreen, Tackle and Leer. The Ev's and IV's are maxed out. It has Pokerus and will be from Emerald. There are no ribbons on it and no contest ribbons. It's OT is Billy, just to make it look real. Everything is believable and nothing is out of the ordinary. It is not shiny either. The condition od it being Coll, Beaty, Tough, etc is also 0. This cheat only modifies slot 1 of your party, so put another pokemon you don't want in the first slot. The rest will be the same.
