Sorry for the long wait but I was hit by the biggest writer block.

Disclaimer- I don't own anything seen here, except for most of the plot

Harry flipped a page in the book as he sat in the library with Hermione and Ron who were reading through books as well. Ron yawned, having slept a total of ten hours, he was still tired when awakened by Hermione pulling him off his bed. He was reading a book on demons and other supernatural creatures Harry could encounter on the job. Hermione was tired as well, only four hours of sleep, but she read her own book on Hocruxes intently. Harry once more looked at the great pile of information provided by Mephisto, all of this dark knowledge should give them an edge when encountering demons, or Death Eaters.

"Good morning everyone!" Ron jumped in his seat as Mephisto exited the shadows behind him. Mephisto walked to the edge of the table and levered himself up on it to take a seat. "I have a mission for you Harry." Harry looked wearily up at the Demon Lord. Mephisto lifted his right hand and a solid image formed. A large muscle bound demon with ram horns, bright green skin and black tattoos. "This Gurnok, Champion of the Pit. He fights whoever is thrown at him, I usually use him to punish souls, but in a real combat situation is almost unbeatable." Mephisto dismissed the image before forming a cup of tea in his hand and taking a sip. "He left because he felt like he needed a challenge, I need you to track him down and tear him apart before sending him back to me. Punish him so he won't do this again." Harry nodded and stood to his feet. Mephisto disappeared without another word, a simple breeze announcing his exit.

"See you Harry." Ron yawned before laying his head on the book he was reading. Hermione rolled her eyes and stood to hug Harry.

"Be careful out there Harry." He returned the hug and nodded before letting go to leave for the main hall where his motorcycle leaned against the wall. Hermione watched him go until the door closed behind him and only sat back down when she heard the roar of the demonic engine of Ghost Rider's cycle. She looked over to Ron who had started to snore, and put the book on Hocruxes aside. She grasped the Darkhold and opened it the page she was on last night, unknowing of the red glow behind her eyes.

The Rider sped along the street in the sunlight uncaring that anyone saw him, he was after his target, nothing else mattered to him. He could feel the demonic energy being released from Gurnok, as he got closer the feeling increased in intensity. He turned his head as Spitfire came up beside him, he shook his head and snorted as reached for his ebony chain. Spitfire moved quickly intending to knock him off his motorcycle, but the Rider swerved to the side as he pulled his chain out, the end transforming into a bladed hook. He threw it out at Spitfire who dodged, the hook tearing the asphalt up into a large gorge, and spun the chain over his head and sent it out again.

Spitfire leapt into the air as the hook sliced through the air under her, as she landed on her feet the hook changed direction in mid-air before coiling around her feet and lifting her into the air. The Rider suddenly stopped, and quickly started to spin the chain above his head, gaining speed until suddenly the chain loosened sending Spitfire flying through the air away from Gurnok. The Rider snorted as his chain rewound itself around him, and with a roar went flying into the air toward Gurnok. As Spitfire landed in the front yard of a simple suburban home she vowed to kick the ass of the Rider.

Gurnok had finished his Champions Throne, throwing aside the guts and entrails that had covered the materials. As he settled himself on the throne he grasped the armrest, his gigantic hand covering the bloodied skull of his last victim. He constructed the throne from the bones of the people of this small village, finding them unworthy as challengers to his power. He had slaughtered every last human in the community to construct the throne to hold his massive body. He settled himself in and waited, knowing that sooner or later someone would come to him, if they were a challenger he would introduce himself and allow them to prepare for the fight, and if they were unworthy he would kill them and add their body to the throne.

Within minutes he could feel the oppressive power of a demon lord, a challenge, and he could hear the roar of a great beast. He straightened in his throne intending to make an impression on the demon coming to him. He looked to the sky to see a roiling cloud cover quickly moving toward him, and he could the demon. All of the sudden a burning corona of light started falling toward him, the roar of the beast joined by the roar of a demon. The light hit the ground at incredible speed creating a large crater that was red hot from the power released on impact, and covered in smoke and dust obscuring the demon. Gurnok leaned forward in anticipation, the smoke dissipating to reveal the Rider astride his flame covered motorcycle. Gurnok scowled and scoffed at the Rider, anger coursing through at Mephisto's impertinence.

"So Mephisto sent his lapdog to try and reign me in, I feel insulted this is the only thing he could send against me." With that he roared and leapt from his throne at the human transformed by the power of a demon. The human raised a hand and swept it to the side, Gurnok was sent flying to the side into a small hill creating a crater. Gurnok got back up feeling as if a giant had slapped him out of the air, he growled and ran towards the Rider who dismounted his cycle, his body slumped. Gurnok raised his arm intending to smash the rider into the ground, but the Rider spun around the blow before punching Gurnok in the solar plexus with all of his strength. The air behind Gurnok was blasted outwards by the force of the blow as a sonic boom, Gurnok stumbled slightly, his head down as he cradled his stomach.

The Rider raced forward intending to finish the fight in one blow, raising his right fist to cave in the skull of Gurnok. His fist was caught at the last second by Gurnok with his left hand creating another sonic boom, the demon grinned, unfazed from the earlier blow except from some slight bruising on his stomach.

"I admit that was surprising," The Rider tried to punch with his other fist but Gurnok caught it with his other hand. They were deadlocked, the Rider straining but the demon Champion showing no exertion. "I did not expect that kind of strength or speed, I was unprepared but now you will not win." The demon slammed his knee into the gut of the Rider knocking the wind out him and sending him stumbling back. Gurnok lazily followed as he spoke.

"Unlike the other demons my power lies in adaptability, I am able to take anything thrown at me and become more resistant to it. When you punched me you also released a burst of your energy. It unconsciously happening or you would have released more and killed me, still you caused me a great amount of damage that will take hours to fully heal." He raised his fist and punched downwards but the Rider rolled to the side but was still sent flying by the force of the punch. Gurnok chuckled as he walked leisurely after the Rider who had got back to his feet. Gurnok moved quickly and within seconds he started trading blows with the Rider causing a series of sonic booms with each hit. The exchange was ended when Gurnok slammed a punch into the Rider's stomach, causing the Rider to stumble back cradling his stomach. Gurnok laughed, looking completely unscathed as he walked toward the slumped Rider.

"The more you hit me the more I adapt to your demon power, there is nothing you can hit me with." He came closer to the Rider raising his arm intending to kill the him in one blow. The Rider whispered something causing Gurnok to stop with his arm raised. "What?" The Rider quickly placed his hand on the upraised arm of Gurnok and spoke clearly in is deep, flanging voice.

"Reducto." The arm exploded into gore, Gurnok roared as he backed away, staring in disbelief at his ruined arm. "I know how your adaptability works." Gurnok looked worried. "You absorb the energy into your body making it your own, until the energy wavelengths match, nullifying every blow from your opponent. Everyone gives off some kind of spiritual energy when they attack, be it demon or human, so you have the perfect defense when fighting anyone." Gurnok said nothing, his face twisted into rage. "It has one weakness, when you absorb energy you can't expel the energy quickly, so if you face someone with another type of energy they can damage you until you are able to absorb enough energy to get rid of your current store and replace if with the new energy." Gurnok chuckled uncomfortably, trying to sound more confident then he felt.

"Your wrong, I regularly face large groups of opponents." He started to back away as the Rider started to come closer.

"I have a guess for that as well, when you face a group they are usually weaker than you or enemies close enough in type be it human or demon that the energy you absorb is enough to cancel every blow because their so weak. You only face opponents one on one when they have the same strength or are stronger." Gurnok continued to back away as he grasped his ruined limb.

"That doesn't explain how you were able to damage me." The Rider chuckled as he pulled he chain from around him, forming it into a large scythe that he put over one shoulder as spoke.

"That's because I'm not just the Rider, I am a wizard." Gurnok's eyes widened as he quickly formed a large broadsword to block the next blow from the Rider. A quick clash of blades continued, as Gurnok spoke.

"How did you figure out my weakness?" The Rider somehow smirked without any lips.

"My best friend is a genius it had to rub off sometime." The Rider leapt back and swiped his hand along the blade of his scythe as he spoke. "Sectumsempra." The blade started glow with an unearthly dark purple light. The Rider moved quickly as Gurnok raised his blade to defend. The Rider swung right through Gurnok and his sword. Severing the demon in twain, causing dark green blood to explode from the release of pressure. The Rider remained untouched by the blood, his fire burning it away before it touched him. Gurnok gurgled in pain as he tried to pull his body together. The Rider chuckled, as he transformed his scythe back into a chain with bladed hooks on each hand.

"I'm going to enjoy tearing you apart." He spun one hook through the air until it was blur of a buzz saw. Gurnok screamed as the Rider tore into his body with a laugh.

The Rider looked down at the unrecognizable hunk of flesh that used to be Gurnok, several hours after he had started. He wrapped the chain around himself again before lifting both hands, and released a stream of bright red hellfire from both hands that turned everything caught in the fire to instantly turn to ash. Seconds later he stopped, his hands smoking, and immediately whistled for his bike. He mounted the hellfire cycle with a chuckle before peeling out and launching into the sky heading for home.

As the Rider headed for Grimmauld place, deep in the part of his psyche where Harry was shoved each time he transformed. The teenage boy was almost catatonic at what he had seen, at what his body did while under the control of a demon.

This is for all of those people who stuck this story over the months, I'm sorry, but I finally hit upon some inspiration and typed this up in a couple hours. Hope you enjoyed, so please Read and Review.
