Malcolm Betruger

"Making progress, Marine? Your journey is futile. You will die, and your soul will be mine!"

- Malcolm Betruger

Dr. Malcolm Betruger is the main antagonist of both Doom 3 and the Doom 3: Resurrection of Evil expansion pack by id Software.

History
In Doom 3, Betruger is the director of all research at the Union Aerospace Corporation research facility on Mars. In Doom 3: Resurrection of Evil, he returns as part of a flying gargoyle-like demon named the Maledict and is leading the forces of Hell. He is an elderly, overworked doctor, whose right eye is grayed over with blindness.

In Doom 3, it is stated in an audio log that at some time before the events depicted in the game took place, Betruger inexplicably entered a teleporter, transporting him to Hell. When Betruger returned, he still looked the same, but he behaved differently. This suggests that Betruger may have been possessed or corrupted by a demonic force, though it is never clearly stated exactly what happened to him. What is clear is that he had made a pact with the demons of Hell in which he agreed to provide a portal that the demons could use to invade the facility, in return for great supernatural power, including a degree of omnipresence and the ability to command armies of demons. Shortly before the invasion, Dr. Betruger acquired the Soul Cube. Knowing that it was the only thing that could stop his plans, he hid it in Hell where no one could find it and use it against him.

Betruger is first seen at the beginning of the game, inside of the Mars Facility Control Tower. He observes a shuttle arrive, carrying Counselor Elliot Swann, Jack Campbell, and a replacement Marine (the player). Later, the Marine eavesdrops on an argument between Betruger and Swann, the latter of whom has been sent by the UAC Board to investigate the disturbing activity surrounding Betruger's experiments. Betruger warns Swann to stay out of his way and cryptically adds that "amazing things will happen here soon." A short while after the demonic invasion, the Marine overhears yet another argument between Betruger and Swann. Betruger appears to be unperturbed by the disaster unfolding around him, and smugly tells Swann that he'll "handle" the situation. Later in the game, Betruger contacts the Marine directly and makes it clear that he is in league with the demons and is plotting to lure the Earth Fleet to Mars. Once they have seized control of the Fleet's ships, they will launch an invasion of Earth itself. A cutscene later reveals that he has gained supernatural powers which enable him to transform other marines into Zombie Commandos. He makes two separate attempts to kill the Marine, first by flooding the area with toxic gasses, and later by opening a portal that pulls the Marine into Hell itself. Both these attempts fail.

Throughout the game, Betruger continues to taunt the Marine and sets his demonic minions upon the player. He typically threatens the Marine with death and the promise that his soul will burn in Hell. Ultimately, however, Betruger's plans are foiled when the Marine recovers the Soul Cube, returns to Mars, and uses the Cube to destroy the Cyberdemon and seal the Hell hole that has been opened below the planet's surface. Five days later, a team of marines and sentry bots arrive at the facility. They rescue the Marine, but are unable to find Betruger. The last scene shows Betruger in Hell, where he has become part of a horrific skeletal dragon-like creature later revealed to be the Maledict.

It should be noted that while in Hell, the Marine is taunted by an unseen presence - one that sounds different than Betruger's normal voice. It is unknown as to whether or not this is still Betruger or an entirely different entity. It most likely is, as the sound files in the paks have the taunts suffixed with bet_, most likely short for Betruger.

As the Maledict
At the end of the game, Betruger is shown in Hell as the Maledict, a giant skeletal dragon-like demon. The Maledict is featured more prominently in the Doom 3 expansion pack Resurrection of Evil, and is the final boss of the game. When a marine, a combat engineer, found the Artifact, he sent the Hell Hunters to get it back as he commanded another Hellish invasion army. When the hunters were defeated, the marine went to hell to destroy the Artifact there. In Hell, Betruger/Maledict demanded that he give him the Artifact. When the marine refused to give it to him, Betruger decided to fight the marine himself. After a hard fight, the marine attempted to shoot Maledict with the Rocket launcher but missed. The Maledict attacked and bit the marine, causing him to pass out. When he awoke, Betruger demanded the Artifact again, but the angry marine instead shoved the Artifact into Betruger's mouth, causing an explosion that killed Betruger and ended his reign of terror.

Trivia

 * Betruger's name comes from the German word "Betrüger" which means "deceiver" or "traitor".
 * Dr. Reinhard from Evil Dead: Regeneration has several similarities to Betruger. In addition to looking similar (with a solid white eye), both were said to have been good before their pacts with the undead. They also have German names.
 * In the E3 2002 demonstration of Doom 3, Betruger wears glasses or goggles, which were removed for the final release of Doom 3. In the demo video, he is shown pushing past a couple security guards to initiate a dangerous test sequence.
 * If on the first level, if you use cheat codes to enter the room where Betruger is, he will be identified as "Joe" - the name for all NPCs the player is not supposed to be able to interact with. He has no lines and will not speak with you.
 * According to the Making of Doom III book, many of Betruger's lines and actions were to be performed by General Hayden, the commander of the military on Mars. Hayden was meant to be the assumed villain, and only later on in the game would it be revealed that Betruger was the true mastermind behind the invasion. Later, the developers decided to remove Hayden's character entirely, and establish Betruger as the villain early on in the game.
