The Doom Slayer had no mercy. He had slaughtered his way through countless hordes of demons, leaving behind a trail of carnage and destruction. He had reached a part of hell that resembled a medieval castle, with majestic spires and elaborate carvings. But the castle was tainted by the dark forces, and its walls were adorned with spikes, skulls, and pentagrams. The Doom Slayer sensed a powerful presence inside, and he was eager to confront it.
He blew up the iron gate with his super shotgun, and entered the courtyard. There, he was met by a group of beastmen, twisted creatures that had horns, hooves, and fur. They wielded axes, spears, and shields, and they roared at the sight of the invader. The Doom Slayer wasted no time, and charged at them with his chainsaw. He sliced through their flesh and bones, and used their severed limbs as weapons. He threw a horn at one beastman, impaling him on the wall. He smashed another one's skull with a shield, and ripped off a third one's arm, and beat him with it. He was unstoppable.
The Doom Slayer had just finished killing some of the beastmen, when he heard a loud thud behind him. He turned around, and saw a baron of hell jumping down from a balcony on the second floor. The baron of hell was a massive demon, with red skin, horns, and hooves. It had a pair of fiery eyes, and a mouth full of sharp teeth. It roared, and charged at the Doom Slayer as demonic symbols blocked all exits out of the Arena.
The Doom Slayer was ready for the challenge, but he realized that he was not alone. He saw two hellknights teleporting in, circling around him. The hellknights were smaller than the baron of hell, but still formidable. They had gray skin, and claws. They snarled, and lunged at the Doom Slayer.
The Doom Slayer was outnumbered and surrounded, but he was not afraid. He pulled out his super shotgun, and fired at the nearest hellknight. The blast hit the hellknight in the chest, sending it flying back. The Doom Slayer then used his meat hook, a grappling device attached to his shotgun, to hook onto the other hellknight. He pulled himself towards the hellknight, and shot it in the head. The hellknight's head exploded, and the Doom Slayer landed on the ground.
But the Doom Slayer was not safe yet. He heard a loud growl behind him, and turned around. He saw a mancubus popping its head out of a pile of corpses that the beastmen were standing by. The mancubus was a fat demon, with two cannons on its arms. It had a large belly, and a small head. It drooled, and charged at the Doom Slayer from behind. It knocked over and trampled some beastmen to death, distracting the remaining hellknight. The Doom Slayer took the opportunity, and switched to his ballista. He fired a bolt of energy at the hellknight, hitting it in the chest. The hellknight staggered, and the Doom Slayer fired another bolt, hitting it in the head. The hellknight's head disintegrated, and the Doom Slayer dashed away.
But the Doom Slayer was not done yet. He saw the baron of hell closing in on him, and switched to his ice bomb. He threw the ice bomb at the baron of hell, freezing it in place. He then jumped on the mancubus, and punched a hole through the mancubus, and jumped off. He then locked on to the last hellknight with his rocket launcher. He fired a volley of rockets at the hellknight, but the hellknight dodged out of the way. The hellknight ran into the crowd of beastmen, who were getting back up after the mancubus knocked them over. The rockets hit the beastmen instead, causing them to explode. The hellknight then dashed to the side, avoiding one of the rockets. But the Doom Slayer fired another rocket, hitting the hellknight. The hellknight fell to its knees, and the Doom Slayer ran over. He stabbed the hellknight through the back with his crucible blade, and sliced up through its shoulder. The hellknight died, and the Doom Slayer pulled out his blade.
But the Doom Slayer was not finished yet. He saw the baron of hell breaking free from the ice, and throwing a fireball at him. The fireball did nothing to the Doom Slayer, but it blocked his vision. The baron of hell took advantage of this, and body checked the Doom Slayer into a wall. The baron of hell then punched the Doom Slayer, trying to cave in his head. But the Doom Slayer caught one of the baron of hell's hands, and broke its arm. He then sliced open its neck with his blade, killing the baron of hell. The Doom Slayer then looked over to the leftover beastmen, seeing the few left broken and bleeding out. He fired a normal grenade at them, and then walked over to the door. The door had a fire energy and a pentagram covered in demonic symbols. It dissolved as soon as the grenade went off, killing the beastmen. He reached a large wooden door, with a carving of a dragon on it. He pushed the door, and entered the garden.
The garden was a nightmare. It was filled with corrupted plants, that had fire and flesh fused into them. The plants writhed and hissed, and some of them had mouths and eyes. The Doom Slayer felt a wave of heat and stench, and he saw the source. In the center of the garden, there was a huge elder dragon, lying on its back. The dragon was fused with the garden, and its lower half was split open, revealing its organs and bones. The dragon's wings were spread out, and its flesh was attached to the walls. The dragon's head was still intact, and it opened its eyes. It saw the Doom Slayer, and it roared.
The Doom Slayer was not afraid. He loaded his rocket launcher, and aimed at the dragon's head. He fired, and the rocket hit the dragon's eye, causing it to scream in pain. The Doom Slayer ran towards the dragon, dodging the fireballs and vines that the dragon spat at him. He reached the dragon's neck, and climbed on it. He pulled out his BFG, and fired a shot into the dragon's maw. The green light was seen going down its throat, melting it all the way. The dragon's head popped, and its stomach blew up, causing green, red, and yellow energy to shoot out. The sky started to cloud, and tornadoes formed. The tornadoes closed in on the Doom Slayer, creating a vortex through time and space. The Doom Slayer was pulled in.
He emerged in another part of the garden, where the dragon's tail was coiled around a tower. The tower was covered with spikes and skulls, and had a flagpole on top. The Doom Slayer saw the dragon's tail twitching, and he knew it was still alive. He also saw a horde of beastmen, half-human and half-animal creatures, running towards him. They were armed with axes, spears, and claws, and they had bloodlust in their eyes. The Doom Slayer grabbed his chainsaw, and charged at them.
He sliced through the beastmen, spraying blood and guts everywhere. He used his dash ability to move faster, and his glory kills to finish them off. He ripped off their heads, tore out their hearts, and smashed their skulls. He felt no mercy, only rage. He heard the dragon roar again, and he looked up. He saw the dragon's head, which was still attached to its spine, rising from the ground. The dragon's eye was gone, but it still had its mouth. It opened its mouth, and unleashed a blast of electric lightning at the Doom Slayer.
The Doom Slayer dodged the lightning, and ran towards the tower. He saw the flagpole, and had an idea. He jumped on the flagpole, and swung around it. He used the momentum to launch himself to the second floor of the tower, where he saw a window. He smashed the window, and entered the tower. He pulled out his Gatling gun. He looked out the window, and saw the dragon's head. He fired his Gatling gun at the dragon, but the bullets bounced off its scales. He realized he had to aim for its weak spot. He aimed at the dragon's stomach, where it was split in half. He fired again, and this time, he hit the mark. The dragon screamed in pain and rage, as its flesh and blood splattered everywhere.
The Doom Slayer smiled, and kept firing. He saw the dragon's head lower itself, and prepare for another lightning attack. He knew he had to move. He jumped out of the window, and landed on the dragon's tail. He ran along the tail, towards the dragon's head. He saw flesh tentacles break out from the ground, trying to hit him. He slid under the first one, and set the second one on fire with his shoulder mounted flame thrower. The tentacle retreated back to the ground, as the fire consumed it. He sliced the third one in half with his chainsaw, and continued his run. He reached the dragon's horn, and grabbed it. He pulled out his BFG, and fired it into the dragon's eye socket. The green light went into the dragon's brain, and exploded. The dragon's head blew up, and its spine snapped. The dragon was finally dead.
The Doom Slayer roared in triumph, and raised his BFG in the air. He had killed the dragon, and cleared the garden. He looked around, and saw no more enemies. He felt a sense of satisfaction, and a hint of boredom. He wondered what his next challenge would be.
As he wondered, he saw something strange happen. The dragon's scales, which were made of stone, started to float in the air, and spin around. They created a whirlwind of stone and dust, that grew larger and larger. The Doom Slayer felt a strong wind blowing, and he heard thunder and lightning.
He looked up and saw the sky turn dark and red. Bolts of red lightning struck the ground and the garden. The plants and the tower caught fire and exploded. The dragon's blood boiled and evaporated. The dragon's soul escaped and screamed. The explosion blinded the Doom Slayer, and everything went quiet and dark.
