Tyrant

The Tyrant is a new monster in Doom Eternal, and the next iteration in the class of cyberdemons. It bears a close resemblance to the classic cyberdemon, with a similar suite of cybernetics, a gored abdomen, and a weapon which replaces its left arm. Unlike its Doom II counterpart, its eyes are not red; instead, they are yellowish-white. It also appears to be equipped with a metallic skeleton and an Argent accumulator, like its immediate predecessor. Their attack behaviors are unchanged, but they don't have the dash ability of the previous iteration, making them very slow and cumbersome.

As of the pre-order trailer, the Tyrant has been confirmed to be a recurring major enemy, unlike its previous iteration.

Tactical Analysis
The Tyrant mainly attacks by firing missiles from its arm cannon. If it cannot see the player, it makes exploding runes appear all around the battlefield. It has a huge amount of health and no weak points. When it sees the player, it takes a moment for it to take aim, so you can use this window of time to attack. It is also slow to turn, so dashing around it is a good way to get a hit in.

Glory kills

 * The Doom Slayer repeatedly stabs the Tyrant in the eye, causing it to crash to the ground.
 * The Doom Slayer uses the Doom blade to cut the Tyrant's leg off. Once it falls to its knees, he beheads it.

Trivia
Despite appearing to have an organic face, the Tyrant's skull can be exposed to reveal a mechanical eye with a red lens.
