Doom Slayer, also known as the Doom Marine or the Unchained Predator, is a primordial force of vengeance. Once a mortal marine, he refused to die after the demonic invasion. Fueled by pure rage, he traversed dimensions to annihilate Hell's armies. Blessed by the Seraphim, he became incorruptible, unbreakable β a god's wrath in a Praetor suit.
π Sentinels of Immora, Fortress of Doom β currently crusading through the legions of Hell, unstoppable and eternal. The demons whisper his name in terror: the Hell Walker.
Born in the 22nd century, the marine known only as the Doom Slayer witnessed the slaughter of his family and brothers-in-arms during a demonic outbreak on Mars' moons. Rather than perish, he was consumed by an endless, focused rage. After being trapped in Hell, he spent eons slaughtering demons, growing stronger with every kill. The Sentinels of Argent D'Nur discovered him in a Colosseum of bones, fighting like a feral god. They named him the Great Slayer. After the fall of Argent D'Nur, the Slayer received the Praetor suit and became the eternal scourge, sealed away only to be awakened once Hell invades again. In the modern age, he woke up β and Hell screamed.
His feats include destroying the Titan Icon of Sin twice, slaughtering the Hell Priests, defeating the Dark Lord himself, and reshaping the fabric of Hell's hierarchy. Doom Slayer does not use guns for protection β he uses them for efficiency. The only reason Hell still exists is because his rampage has not yet reached every crevice.
"In the first age, in the first battle, when the shadows first lengthened, one stood. He chose the path of perpetual torment."

"You can't just shoot a hole into the surface of Mars."
β Doom Slayer (proceeds to do it anyway)
"They are rage, brutal, without mercy. But you. You will be worse."

Argent-enhanced armor, nearly impervious to conventional weapons and demonic attacks. Energy shielding, advanced target acquisition, and integrated rune system. Self-repairs through collected Argent energy and demon essence. The helmet contains a visor that can analyze weak points and demon vulnerabilities in real time. It is said that the suit feeds on demon adrenaline.
After the Slayer was found by the Night Sentinels, he underwent brutal combat training and was blessed by the Seraphim β granting him superhuman speed, durability, and immunity to the temptations of Hell. His strength allows him to tear demons limb from limb with his bare hands. He uses advanced guns but never relies on them.
