>>31430331i've kept/traded up through XY several boxes of hacked shinies that my little brother caught for me in Diamond using his Action Replay
they are obvious hacks (all caught in Masterballs, at level 3-4, on route 201), and don't purposely have any beneficial natures/ivs/etc. i never use them in online battles, or show them to my friends.
i love them all, and i headcanon them as the "mysterious foreigners" within my PC boxes each generation.
