20 Greatest Arrowverse Villains

20. Mallus

Initially, Legends Of Tomorrow’s season three did its level best to present primordial demon Mallus as a terrifying harbinger of doom.

Escaped from his prison of centuries, this sinister force of darkness corrupts and possesses more than one person in true Exorcist style while the team desperately try to find a way to put the djinn back in the bottle.

Unfortunately, the climax to his tenure as the show’s Big Bad completely eradicated any menace that had been built up over the preceding seventeen episodes, with the combined Legends using their ersatz Infinity Stones to create a super-Beebo, a blue fluffy toy empowered with the ability to destroy the millennia-old demon.

Mallus would be a lot higher on this list if they hadn’t gone for the Ghostbusters ending and had their supervillain creamed after a WWE-style spotfest with a plushie.
