Doom Slayer - Berserker - DOOM - Requested

Class: Berserker 

True Name: Doom Slayer(Doomguy)

Alignment: Chaotic Good 

Original Series: DOOM 

Lore: Doomguy, known in myth and legend as the Doom Slayer, is a relentless warrior whose name resonates across Hell and beyond. Born as a mere human, he became the ultimate embodiment of rage and vengeance, destined to wage an eternal war against demons. His saga began with the invasion of Mars, where he faced hordes of Hell's creatures alone, driven not by orders but by an unquenchable desire to destroy every demon in his path. Over time, his rage evolved into something divine—an unstoppable fury that transcended mortal limits. His soul was cast into the Abyss, but instead of being consumed, he fought on, becoming an unkillable force feared even by Hell's highest lords. 
The Doom Slayer was eventually imprisoned in a sarcophagus to contain his wrath, but even that could not hold him forever. He was freed once more to resume his crusade, a lone warrior who defied the gods and demons alike. His legend became an omen of annihilation for all creatures of darkness, and his name was whispered with dread across dimensions. As a Berserker-class Servant, Doomguy embodies unrelenting fury, immune to despair, exhaustion, and fear. However, his connection to wrathful vengeance makes him volatile and difficult to control, as he obeys no master—only the call to battle.

Class Skills:
-Mad Enhancement (B): Doomguy's raw fury fuels his combat abilities, placing him at Rank B in Mad Enhancement. This rank boosts his physical parameters immensely, allowing him to engage enemies with near-limitless stamina and superhuman strength, but it comes at the cost of limiting his verbal communication and making him nearly impossible to control. His rage is not mindless, however. Unlike most Berserkers, Doomguy retains enough focus to distinguish allies from enemies, though his interactions with others are curt, hostile, and wordless. He is driven purely by instinct and rage, making it impossible for enemies to intimidate or manipulate him. His thoughts are singular and direct: destroy all enemies until none remain standing. 

Personal Skills:
-Unyielding Fury (A): Doomguy's rage is inexhaustible, granting him Rank A in Unyielding Fury. This skill ensures that Doomguy's strength and stamina increase the longer a battle continues, allowing him to shrug off injuries that would cripple other Servants. As his rage deepens, his blows become more powerful, and his speed accelerates, giving him the edge in prolonged encounters. The more demons, monsters, or enemies he faces, the more efficiently he fights, as if every opponent only fuels his bloodlust. In battle, his fury transcends mortal limits, granting him brief moments of invulnerability where his rage renders him immune to pain or mortal wounds. However, once a fight ends, the exhaustion of his unrelenting combat catches up to him, leaving him vulnerable if not immediately re-engaged. 

-Anti-Demon Authority (EX): Doomguy's existence is anathema to all demonic creatures. At Rank EX, this skill gives him unmatched effectiveness when battling infernal beings. Against demonic or hellish enemies, all of his parameters are temporarily boosted, and even those with regenerative abilities find their wounds irreparable under his relentless assault. This skill also grants Doomguy an instinctive ability to detect demonic presences or curses, making it impossible for such entities to hide from him. In addition, demonic enchantments and magic dissipate when in his presence, as his hatred disrupts the flow of infernal prana. This makes him an invaluable ally against enemies aligned with Hell or other dark dimensions. 

-Indomitable Will (A): Doomguy's mind is a fortress of rage and purpose. At Rank A, this skill grants him immunity to mental interference, including fear, despair, and illusions. His unbreakable will allows him to fight on even in situations where other Servants would retreat or falter. Even abilities that manipulate perception or induce madness have no effect on him, as his mind is too focused on his mission to be swayed. This indomitable nature also makes him resistant to command spells, as his overwhelming willpower allows him to ignore even the direct orders of his Master if they conflict with his goal to destroy evil. His single-minded determination can be both a strength and a weakness, as he will not stop fighting until every threat is eliminated, regardless of tactical considerations. 

-Praetor Armor Synchronization (B): At Rank B, Doomguy's Praetor Armor not only protects him but also enhances his physical capabilities by synchronizing with his body and combat style. This armor amplifies his strength, speed, and endurance while providing a regenerative effect that heals minor injuries over time. The armor also absorbs ambient energy from magical or infernal attacks, converting it into power for Doomguy's next assault. However, the synchronization process drains his prana over extended periods, making it difficult to maintain peak efficiency in drawn-out battles without proper energy sources. 

Noble Phantasms:  
-Name: BFG 9000 – Annihilator of Worlds
-Rank: A
-Type: Anti-Army 
-Ability: The BFG 9000 is the ultimate weapon in Doomguy's arsenal, capable of unleashing cataclysmic energy blasts that disintegrate everything in their path. This Noble Phantasm fires a massive sphere of energy that travels slowly but radiates destructive pulses, vaporizing enemies and magical constructs within its radius. Upon impact, the sphere detonates in a massive explosion, wiping out anything caught in the blast. The BFG's energy is so volatile that it disrupts dimensional boundaries, making it effective against both physical and spiritual entities. Its primary use is in large-scale battles where Doomguy can obliterate entire armies or magical fortifications with a single shot. However, the weapon's immense power consumes a large amount of prana, limiting its usage to once per engagement unless properly recharged.
