Titan

Titan are gigantic demons in Doom Eternal. Despite their incredible size, most titans are not enemies in the game, they are instead referred to as thralls, mere beasts of burden for the forces of Hell.

The first titan encountered in the game is seen in Hell on Earth after killing Deag Nilox. It wanders away aimlessly, its role as a Hell barge finished after the death of its Hell priest.

The second titan is seen in Taras Nabad. It is already slain, said to have been defeated by the Doom Slayer long ago. The hilt of the Crucible is retrieved from its heart.

Other enthralled titans are seen in Nekravol. Notably, in Nekravol - Part II, two of them hold the Argent transmitter tower aloft on chains. Destroying these chains allows to destroy the transmitter and proceed to the next level.

The last titan is the Icon of Sin, met in Final Sin. This is the only titan that is actually fought during the game.
