From the top of my head:
Regice in gen 3, as well as Jolteon and Cloyster.
Electivire, Dusknoir, and Ninjask in gen 4.
Donphan, Jolteon, Metagross in gen 5, as well as dugtrio after AT ban, and Ninetales/Venusaur after Drought+Chlorophyll ban.
Arguably Azelf in gen 6, since it was forced into OU after the last tier shift because of a copypasted team during the M-Sableye suspect. Sylveon had a protracted presence as well.
I can't think of a truely shitty OU mon for 7, most of them were congested into UUBL; even Mimikyu dropped near the end.
