Hmm i might have to investigate on this seeing as i run in there to check if scraggys might want to hide in crates (even though i have the one from the pokemon don event) but i might have to check again hopefully that punk hands over this mysterious pokemon.
Edit: he wasnt in the room before where you fight the scrafty gang but i can confirm (after a child swore at me) that he is in obsidia slums and challenges you to a battle. he is in the room after the roof. after beating him in a battle he tells me he sold it for a weeks worth of food to a gang in north obsidia. please don't tell me this is gonna be as irritating as the ralts corrupted pokeball event ;-;. also ame if you read over this forum you may remember me as the guy form PO that you beat once and then i beat you from a rematch. maybe the name 13gamer2000 is fermiliar.
Edit 2: Also i have realised why that event is incomplete seeing as when you go north of obsidia only things you'll find i:
1. a dead end with a ace trainer at the end of it
2. a pokemon center with the daycare,castform and vulpix event areas are
3. obsidia department store, another building, people and a pathway to the onyx ward
so i guess this mysterious pokemon will never be discovered. it could be something everyone wants like a feebas it could be a exclusive fan made pokemon that ame felt like putting in. OR it could be what you least expected (Stares at magikarp) or it could be a egg Who knows any ways thanks xiri for helping me atleast get part of the obsidia thief event complete. (waits for E14 then E15)
