So here's what happened.There is a man in Ambrette Town that asks you to show him Genesect, so i showed him the Genesect i got from the white2 event, he said"OMG MIKE YOUR S.EXY HERE IS GENESECT'S DISC THINGS CAUSE YOUR SO HOT!" After that he says"Ya know Genesect has been rumored to be in Glittering Cave." i was like NO WAY IM GOING THERE,i arrive there breaking rocks and while i'm walking through the cave,i get into a wild pokemon battle,and the pokemon WAS A SHINY MACHOP!! IT WAS SO COOL!!!!!
