Mancubus (Doom Eternal)

The mancubus returns in Doom Eternal with a new design based on its appearance in Doom II. It largely maintains the same attack behaviors as the version in the previous game, including the ability to use dual flamethrowers at short range in addition to its usual fireball launchers.

Glory kills
The Doom Slayer is able to spear the glowing heart-like organ in the monster's chest using his arm-mounted blade, and then stuffs it into the mancubus's mouth. The monster then explodes shortly after.
