Doctor Who Villains from the Classic Series Who Should Return to the Revived Series

They really should explain how the hell the Silence made a TARDIS, and Omega is the best candidate. As he is one of the first people to invent these and may have escaped the Time War, as he is trapped in the anti-matter universe, it would be fulfilling for him to return.

Yeah they should, they're the ones that used to scare me - EvilAngel

If the Silurians have returned, so should their Aquarian cousins. They were great in the Classic Series, but should be given modern treatment.

Why bring back The Great Intelligence without the Yeti? - RickyReeves

I actually quite liked the robot, a return to the revived series could be quite awesome though. - RickyReeves

The Curse of Fenric is one of my favorite Classic Doctor Who stories and he's possibly one of the darkest villains I've seen on the series. Though knowing Steven Moffat, he's either gonna kill him off or make him an ally for the Doctor, which I'd absolutely hate to see.

They were great in the Visitation and they need to appear again!
