Dread knight

The dread knight is a new monster which occurs in Doom Eternal. It appears to be a more advanced form of the Hell knight, with the addition of cybernetic components including two energy blades attached to its arms. Unlike the hell knight, the dread knight can leave damaging areas on the ground as well as launch a bolt of energy from its blades.

Pre-release
The dread knight first appeared, unnamed and without elaboration, in the Doom Eternal cover art which was revealed in the immediate wake of the BE3 2019 presentation. The monster's name was rumored after release of a Slayers Club exclusive piece of art which referred to it as such, but this was not officially confirmed until the QuakeCon 2019 keynote presentation on.
