List of Notable Pokemon this person had before he sold the game to Gamestop:
(I haven't the slightest as to what the IVs are)
Ho-oh (level 83, Adamant)
Articuno (level 79, Rash, holding an Abomasite for some reason)
Zygarde (level 75, Quiet)
Mewtwo (level 81, Mild, holding a Heat Rock for some reason)
EDIT: Some lucky trainer claimed all the legends.
There are also some decent-natures pokes, pokemon with pokerus and starters, but didn't list them because I figured those would be easier to obtain.
If you want any of these, wall message me. My friend code is 1993 - 9253 - 4765, this person's IGN is stampy.
