Maledict

The Maledict is the final boss in Resurrection of Evil, first shown in Doom 3's ending cinematic. It is shown on RoE's box art.

The Maledict looks like a dragon with a large set of wings, two legs with clawed feet, a long tail and a head shaped like a demon skull. It emits a loud, piercing scream and has empty eye sockets (and is thus possibly blind, uses echolocation (with its screams), or sees via supernatural powers). 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 seems to be more powerful than the Cyberdemon because its attacks penetrate the invincibility granted by the Artifact, and as many players have commented on how the Maledict boss battle is considerably more difficult.

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 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.

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 transformed into the large, twisted form known as the Maledict, with Betruger's head at the end of the creature's tongue. Its appearance at the end of Doom 3 demonstrates his pact with the creatures of Hell and his power above the willing of most demons in Mars.

It is never specified exactly what the connection between Betruger and the Maledict is. Whether Betruger merged with the Maledict or is the Maledict is never explained. It uses "us" to refer to itself as well as all of Hell. Though given Betruger's personality change after his first trip through the portal, it may be possible that the Maledict inhabited Betruger's body and that Betruger's soul is lost. 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 Maledict's mouth, resulting in a massive explosion that kills the Maledict and Betruger, whose skull 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.

Trivia

 * Maledict could come from the Latin words Malus meaning evil and dictus meaning to control/Dictate, meaning Maledict means Evil Dictator, which matches Betruger/Maledict perfectly.
