10 Doctor Who Villains Who SHOULD Return

10. The Sycorax

After waking up from a rather long nap, the Tenth Doctor's first adventure saw him successfully defend Earth from a hostile race of aliens called the Sycorax.

While their skeleton-esque faces made for a terrific bit of creature design, they weren't exactly the most memorable of villains, but all the same, a return for the Sycorax would be most welcome - mainly due to where their story last left off.

To recap: the Doctor battles the Sycorax leader in a sword fight, beats him, and then absolutely humiliates him by killing him with a precisely-thrown satsuma. The rest of the Sycorax then attempt to leave planet Earth, but Harriet Jones has other ideas - in a cold move, she orders their ship to be destroyed instead.

Crucially though, that was just one tribe of Sycorax. There are plenty more of them out there in the universe (as evidenced by their cameos in The End Of Time and The Magician's Apprentice), so wouldn't it be fascinating to see them return to Earth in a revenge story, forcing the Doctor to deal with the consequences of Harriet's actions?

The 2008 comic-book story The Widow's Curse even explored a plot like this, with the wives of the dead Sycorax tribe bumping into the Tenth Doctor and Donna. Sure, we don't get a lot of "sequel episodes" in Doctor Who, but we should - and this one would be great to see.
