The Crime Syndicate (Earth Two), Mandrakk (Final Crisis), Reverse Flash (Flash), and Barbatos (Metal). I knew Mandrakk and barbatos is only a plot-convenience villain, but I think they still had hidden untapped potential.
The Controllers shouldn't be overlooked. They don't like you, they'll cook up a Sun Eater and let it run amok.
Does Epoch with his Revision Mechanic count ? After all, it's what can potentially allow Darkseid to rewrite the whole history of the Multiverse.
Perpetua is also not half-bad. She could be used better, but she got a lot of potential, I think.
Nekron is a biggie.
The Manhunters have proven to be virtually impossible to completely wipe out.
Brainiac is a giant threat if handled properly.
Parallax, of course
Nekron
Manhunters
Brainiac
Impierex
Barbatos
Perpetua
Pull List: Detective Comics, Batman, Flash, Justice League, Future State

There's only one answer, really:
IMPERIEX
Dan DiDio?
