Maykr drone

The Maykr drone is an enemy in Doom Eternal, found only in the final few levels in Urdak.

They tend to stay a fair distance from the player and shoot volleys of weak energy blasts; in melee, they attack with whips of light. Their body is covered in strong armor that makes them surprisingly durable for a Fodder enemy, but their head is vulnerable, and killing them with a headshot will release health and ammunition.

Lore
Drones make up the majority of Urdak's population; like most other Maykrs, they have individual identities but are biologically unable to defy an order from the Khan Maykr. As a result, they give the impression of functioning as a perfectly synchronized colony. Their bodies are not yet able to handle the strain of interdimensional travel, so they never leave Urdak.

Trivia

 * When the player interrupts the Maykr's hell ritual to summon and then control the Icon of Sin, the Icon releases an energy wave of some kind which seems to affect all the Maykr drones at the ritual (and presumably throughout that stage). This may be why they fight as they appear to have been corrupted. Alternately, they could just be following the Khan Maykr's command to stop the player at all costs.
