Editing Doom (section)

====Bosses====
The bigwigs of Hell, ranging in power and influence from greater daemons to Chaos Gods/C'tan-tier entities in their own right. These enormous creatures are characterised by having their own dedicated health bars on the UI, fights that often go into multiple phases, dedicated arenas and resistance or outright immunity to the Slayer's superweapons.

*'''The Cyberdemon''': A Baalgar-class Shadow Lord, reclaimed from the UAC's expeditions to Hell and the crown jewel of their Demon weaponisation program. Also hinted to be the original Cyberdemon slain by Doomguy atop the Tower of Babel all the way back in Doom 1, having brought himself back to life out of sheer psychotic hatred at Doom Guy. He does it again in the middle of the boss fight after the Slayer teleports to hell, though the kill after this sticks as the Slayer impales its head with its own horn.
*'''The Hell Guards''': Three armoured suits powered by wormlike creatures, tasked with defending the Demonic Crucible from those who seek to claim it from its resting place in the Necropolis. The Slayer destroys the suits and tears the worms.
*'''The Spider Mastermind''': The Aranea Imperatrix, resurrected via the unholy union of the Dark Lord of the Fourth Age and a female "keyholder", Olivia Pierce. Gets her head blown apart by being forced to deepthroat the BFG-9000, killing the Dark Lord of the Fourth Age and putting Pierce out of her misery.
*'''The Gladiator''': The Last Living Hell Knight of DOOM II and, unlike the Doom Hunter, has survived the extinction event that is the Slayer. In fear of the rampage suffered by the old Hell Knights, the Gladiator killed his master and imprisoned his soul in his shield, making it almost invincible without an exorcism. Its fight is split into two distinct phases.
** Phase 1: The Gladiator is armed with a flail attached to a retractable chain for close and distant attacks, and bears a gargantuan soul-vessel shield. The shield itself blocks all incoming damage, can fire a ghostly afterimage of itself when forcibly coaxed, and can be slammed on the ground as either a close range AOE attack or to summon demons to the arena. Like the Marauder, if the Gladiator's eyes blink green you have an opening to shoot him with any weapon, though the Ballista or Super Shotgun is still preferable. A headshot will stagger him for a glory kill, but the Slayer will simply beat the shit out of him. One thing to note is that his shield will also blink way before the Gladiator actually performs an attack; once for a quick attack, and twice for a heavy attack. Phase 1 ends with the Slayer knocking the Gladiator down for long enough to stab its shield in its eye, destroy it outright and freeing the dead masters soul stuck in it.
** Phase 2: Now vulnerable, the Gladiator goes ballistic with TWO flails, spinning one as an attack-deflecting shield before chaining all-out flail whips and leaping slams. The best approach now is to shoot at it when it isn't spinning its flail, especially when its trying to force you into a game of energy jump-rope by boxing you in with both its flails. After weathering down the beast to its bones, the Slayer finishes off the last Classic Hell Knight by crushing its skull beneath its own flail.
*'''The Khan Maykr''': The supreme ruler of Urdak following the Father's disappearance, whose speech, mannerisms and goals make her come across as a haughty, insufferable fusion of an Eldar and a C'Tan. Once her energy barrier is down due to sustained firepower, Slayer needs to get close to her to Blood Punch her in her Energy Sphere five times. During the encounter she has a tendency to deny Slayer the ground (quite literally) by temporary making it damage him with power surges, that get bigger after every punch. Also, the only ammo source during that encounter (not counting few ammo boxes) are Makyr Drones. 
*'''The Icon of Sin''': A legendary titan, resurrected into the body of the Son of the Betrayer, [[Chaos_Spawn|deformed and warped beyond recognition]], his very existence in Realspace causing destruction and madness. It's described that, if left unchecked, it will drag the entire dimension to Hell through a supermassive black hole - so basically if one of the Chaos Gods themselves manifested in Realspace. The Khan Maykr thought It could be controlled using the Soul of the Betrayer's Son, putting it into [[Power_Armour|Power Armour]] for insurance. But then, the Doom Slayer stabbed the heart containing the son's soul with a dagger provided by the Betrayer ([[Matt_Ward|though without carving the Name of the Betrayer into it]]), setting the soul free and, with it, releasing the beast from Maykr's control. The battle itself is, on paper, pretty easy: eight pieces of the Icon's armour must be destroyed (head, both upper arms, both forearms, both pectorals and abdomen) using your whole arsenal. While doing so, lesser demons will try to harass you and distract you from the Icon. Just don't forget, you're fighting a ''Titan'', and fists that big tend to ''hurt''. With the armour's destruction, the whole process starts again in the second phase, but this time, you chip away at the flesh and bone of those same regions until the Icon collapses, giving you time to ram your Crucible into Its Brain.

*'''The Trial of Maligog''': An endurance test involving giant eyeballs housed in giant cubes, and the final challenge before one may be allowed passage to the Hall of Souls.
*'''Samur Maykr''': The Seraphim, the right-hand man of the Father who imbued the Slayer with the power of a Primeval, now having undergone total Transfiguration into a purple, winged monstrosity with an exposed brain.

*'''The Dark Lord, Davoth''': The original Dark Lord created by the Father as a Primeval, one of the first gods. Doomguy's equal. Designed to truly care about his People, he spiralled out of control in the search of eternal life, to save his people from death. Formerly a caring guardian, he tortured everyone who slightly deviated from this goal. After Davoth got imprisoned in his soul sphere by the Father, demons apparently fought one another to claim his title while he still whispered his influence to them. The Dark Lord of the First Age after Davoth made the deal with the Khan Maykr and the most recent one, the Dark Lord of the Fourth Age is implied to have been the Spider Mastermind that possessed Olivia Pierce before getting her head blown off by BFG-9000. Davoth himself apparently prevented anyone from becoming Dark Lord of the Fifth Age as he was released from his soul sphere several months later. Currently only seen in one cutscene after his soul sphere was unlocked and everyone hoped the final fight was the same as an Unreal Tournament/ Quake Deathmatch.
**Turns out the backstory from the previous paragraph was propaganda from the Maykrs. He's actually the original Father, God of all creation. The Maykrs betrayed him, stole his power to create a new Father (the one who would become VEGA), but that turned out to be a ''really'' bad idea. He's been scheming various ways to get revenge for over a decillion years, up to and including engineering the decay and downfall of the Maykrs from within, ascending one lucky individual into becoming the Slayer for revenge-by-proxy (unluckily for him, that person happened to be the incorruptible Doomguy), all the while trying to turn Hell and its capital city of Immora into the immortal paradise he always envisioned. But unfortunately, his plan still involves lots and lots of demons roaming free across the universe, and the Doom Slayer can't have that. Gracefully accepts his death in battle, and is actually so serene in his final words it is kind of implied that he knew that the Slayer would kill both him and the traitors but he had spent so much time in prison it is worth dying to see the bastards get killed first.
