Malevilus

The Malevilus were a malevolent humanoid race, described as "a form of anti-life that feeds off death." They had batlike wings, horned heads, and a general demonic appearance.

On an alternate Earth, five Malevilus named Babiyon, Abiss, Epok, Nekros and Magog took on the form of Roman gods and supplied the Roman army with technology, allowing it to expand across the galaxy. In turn the Romans offered up prisoners for sacrifice.

The Doctor ended their rule by televising the image of Magog, showing the Roman people the true faces of their "gods" and inciting them to go into open revolt. Magog was trapped in an empty dimension within the Doctor's TARDIS, and the rest of the Malevilus tried to escape in their spacecraft, which exploded on take-off, killing them all.

 * The Malevilus were similar to Krillitanes in appearance. The Doctor had already heard of the Malevilus, so it would seem that they exist in his own universe as well.
