The Cyberdemon is the final boss and most powerful monster of Doom 3. It is found at the Primary Excavation Site, where it stands guard over the massive Hell Hole. It stands roughly 20 feet tall, more than 3 times as tall as a human soldier. Like its original counterpart, the Cyberdemon attacks by firing a salvo of 3 consecutive rockets from its arm-mounted rocket launcher. Unlike the original version, it now has a melee attack as well: the monster can stomp on the player, killing them instantly.
Unlike its original counterpart, it cannot be hurt with conventional firepower; instead, the player has to utilize the most powerful weapon in Doom 3, the Soul Cube, to kill it. The Soul Cube states that only it can kill "Hell's mightiest warrior" presumably referring to the Cyberdemon. It takes 4 shots from the Soul Cube to kill the Cyberdemon. Fortunately, there are plenty of lesser demons on the level that can be killed to charge the Soul Cube.
While the Cyberdemon overall retains its appearance as a minotaur-like giant, there are some differences of this new incarnation of the monster compared to its classic counterpart. This incarnation has a long tail, extending from the machinery on its back, and both legs are mechanical - as opposed to its original version, whose only mechanical leg was the right one. Another noticeable difference is that its rocket launcher is now located on the right arm instead of the left one.
The Cyberdemon did not make an appearance in the expansion pack Resurrection of Evil, so the one that was killed at the end of Doom 3 was presumably the only one.
The Cyberdemon is also the only monster from the original games to be a boss.
In Slender Fortress Edit
Cyber Demon is in the Doom 3 pack, He is another boss that attacks by using fireballs from the weapon on his right arm, and recently he is the biggest Fireball shooter boss right now, and because of how big he is, he might not shoot fireballs because of his arm gets stuck in the ceiling avoids the boss to shoot, since he is a fireball shooter, pyro and medic are highly recommended for this boss, he also one hit kills any class, so attempting to juke this boss is an EXTREMELY bad idea!
