Maledict

The Maledict is the demonic reincarnation of Dr. Malcolm Betruger. He serves as both the main antagonist and the final boss in Resurrection of Evil. The Maledict is first shown in Doom 3's ending cinematic, and is shown on RoE's box art.

The Maledict appears as a mostly skeletal gargoyle with a large set of wings, two legs with clawed feet, a long tail and a head similar to a Forgotten One. He emits a loud, piercing scream and has empty eye sockets. RoE's ending cinematic shows that the demon is very large compared to humans, able to swallow them whole.

While not invulnerable to conventional weaponry, the Maledict is extremely potent in combat because its attacks penetrate the invincibility granted by the Artifact. The Maledict can withstand multiple BFG and Rocket hits even when augmented by the berserk ability of the Artifact. In the final cutscene, the Maledict appears unharmed by the Marine's guns, but it is eventually killed by the Marine using the Artifact.

Combat characteristics
The final battle consists of two phases. In the first phase, the airborne Maledict has 2500 hit points and summons Forgotten Ones to attack the player. It also can hover at the edge of the platform and spew a spread of several fireballs at the player, and jet across the platform leaving behind a Flamewall stream in its wake much like that of the Arch-Vile. After the Maledict's health has been reduced to less than 25%, the second phase of the battle begins. Maledict's health is reset to 5000, and the demon proceeds to retreat to the giant skull-shaped volcano on the battlefield and rains down fireballs from the sky. It also continues to use its Flamewall attack, which deals massive damage to the player.

Tactical analysis
To defeat the Maledict, the player is need to use the Artifact. Taking advantage of helltime power, the player can fire at the Maledict using his strongest weapon (preferably the BFG 9000) with greater accuracy. The Artifact's berserk power also increases the damage done to the Maledict by the player's weapons, allowing them to wear down its considerable 2500 hit points much more quickly. The best time to attack the Maledict is when it hovers over the skull-shaped mountain and summons Forgotten Ones; at this time it flies in a predictable pattern and remains in view for the longest period of time.

During the second phase of the battle, there is a "safe spot" from the Maledict's meteor shower attack, right inside the curve of one of the giant skull's horns, just to the left of the Maledict's perch. The player can fire at the Maledict from this position while safe from the raining meteors, although they will need to dodge around whenever the Maledict flies off to avoid its flamewall attack, or they could save the artifact for phase 2 of the battle and use it to slow time to allow the player to throw the meteors back at the Maledict.

Plot details
A recon team, having rescued the young Marine after he defeated the Cyberdemon and sealed the Hell hole, never finds out about Bertruger's whereabouts. It turns out that the mad scientist has been transformed into a large, twisted skeletal monstrosity, with Betruger's head at the end of the creature's tongue. Its appearance at the end of Doom 3 is initially left open to interpretation as to whether Betruger is being rewarded by Hell for his loyal services, or punished for failing to kill the Marine. The Resurrection of Evil makes it clear, however, that this was part of Betruger's pact with Hell and his power over most of the demon forces.

The connection between Betruger and the Maledict is never exactly explained. Whether Betruger merged with the Maledict or is the Maledict is never explained. It uses "us" to refer to itself or possibly all of Hell. Given Betruger's personality change however after his first trip through the portal, it may be possible that the Maledict's spirit inhabited Betruger's body and that Betruger's own soul was consumed (this is supported by the fact that Betruger sometimes refers to the forces of Hell as his "children"). It is not known whether Betruger is a part of the monster or if he is controlling it. Either way, he does not seem to mind, as he apparently sees his new form as preferential to staying human (referring to everyone as "Mortals").

In Doom 3: Resurrection of Evil, when confronted by another heroic Marine, older than the first one that killed the Cyberdemon, Betruger's head talks about the artifact, revealing it is a powerful object meant to be used by forces of hell, and as speaking of the forces of hell by using the word "us" he reveals his plans of another invasion, and how these plans are ruined by the Marine.

When the Maledict's final 5000 hit points have been exhausted, the ending cinematic shows the demon swooping down at the Marine. The Marine fires a rocket which misses and the Maledict lunges and promptly grabs him with its jaws, swinging him around over its head and then throwing him down to the ground. The Marine passes out. When he wakes up, he is greeted by Betruger's head. Betruger says, "Return what is ours," referring to the Artifact. The angry Marine shoves the Artifact into the Betruger's mouth, resulting in a massive explosion that disintegrates both the Maledict and Betruger. The only thing left is Betruger's human skull which is seen rolling out onto the ground. The screen whites out completely and the voice of Dr. Elizabeth McNeil is heard saying, "Marine...? Marine... Welcome home." This final scene is ambiguous and open to interpretation. Probably what Dr. Mcneil is reffering to is heaven. since the Marine sacrificed his life for Humanity and Saved earth from Demons its most likely heaven

Trivia

 * Maledictum is Latin for a curse, (literally meaning "evil speech" or "verbal abuse"), which references Betruger's transformation into the Maledict.
 * Maledict could come from the Latin word maledictio meaning Speaking Evil, which matches Betruger/Maledict perfectly.
 * Maledict's appearance also resembles Kronos from Doom RPG.
