Omega

Rassilon has had the “megalomaniac rogue Time Lord” gig well and truly pinned down in modern-era Doctor Who but arguably the biggest classic villain yet to appear, Omega, could give him a run for his Gallifreyan money. With a visual appearance that fuses Sauron and Doctor Doom, Omega certainly has the intimidation factor and a contemporary makeover could make the villain truly menacing.

Last seen on television being defeated by the Fifth Doctor, Omega has a natural hatred for Time Lords and control over the power of anti-matter, positioning him as a powerful opponent for the Doctor to encounter. It’s surely only a matter of time before this character re-emerges.

The Mara

First appearing in the “Kinda” serial, The Mara is a mysterious snake-like being capable of infecting and possessing unwilling hosts, with the only giveaway being a snake tattoo on the host’s arm. Although a giant rubber snake is unlikely to be warmly received by fans in 2018, the idea of having an unseen enemy take over the Doctor’s assistants is a concept that contemporary audiences could certainly get behind.

The Mara has been mentioned in Doctor Who spinoff Torchwood, so it certainly still exists in the modern era (even if it would need a visual overhaul) and it could be fascinating to see a re-imagining of The Mara’s trippy home-world, the ominously titled “Dark Places of The Inside”.

Black Guardian

The Black and White Guardians are perhaps the closest things to God-like beings to have featured in Doctor Who and, as such, their absence over the past thirteen years could be considered somewhat surprising. The Black Guardian is supposedly an embodiment of evil and chaos but was thwarted by the Fifth Doctor and his companions in the villain’s last on-screen appearance, “Enlightenment”.

Although the magnanimous White Guardian promised his counterpart would return, the Black Guardian has only appeared since within the franchise’s extended media and is overdue another appearance on television. A story featuring the Black Guardian attempting to corrupt game-show-host-turned-Doctor Who-companion Bradley Walsh would be most welcome.

The Celestial Toymaker

First Doctor villain The Celestial Toymaker only appeared once on television but has been prominent in comic and audiobook releases and it’s not hard to see why the character’s appeal has endured. Although the Toymaker is an omnipotent being that exists outside of the universe’s regular laws of physics, he eschews the usual trope of wanting to take over the world in favor of forcing lesser beings to take part in a variety of childish games.

Wider media has positioned the Toymaker as another Guardian but whether the TV show opted to go down this route or not, the villain’s origins, motivations and backstory are still a relatively blank slate, despite him debuting in 1966. Additionally, the Celestial Toymaker’s penchant for making innocent people compete for their freedom makes him an ideal and unique opponent for The Doctor.

The Axons

Even the most ardent Whovian would have to admit that Doctor Who villains in the classic era rarely looked scary or convincing to anyone over the age of ten and with the limited budget and technology available, the best option was often to keep the designs simple. This may explain why the gold-bodied Axons left such a huge impression despite only notching up a single stint on TV.

Peter Capaldi himself expressed an interest in seeing The Axons reinvented in the modern era due to their God-like appearance covering a far more horrifying form and although Steven Moffat was never keen on the villains - he likened them to BAFTA award statues - new showrunner Chris Chibnall may have other ideas.
