An air of tranquility hung in the air of the desolate forest. A young man with tanned skin and black hair walked down a dirt beaten trail

"I sense we are in danger," Diablos whispered inside Leon's mind. Leon Immediately stopped in his tracks.

Another man came down the trail in the opposite direction this one was a bit thin and taller than a normal person. Long brown hair covered his face as he walked with his head facing toward the ground.

"This man is a threat, kill him!" Diablos whispered again in a menacing tone.

The other man stopped in his tracks and looked up into Leon's brown eyes with his own green ones. "So you're the one harboring the demon," He questioned. Sliding on a pair of brass knuckles, he waited for an answer.

Leon hesitated for a few seconds. "Yes, I am the one with diablo sealed inside." Sensing danger, flames began to flicker in his hands.

"Guess the story was true," the other man responded. His fists clenched as he sprinted forward towards Leon. "I, Serafino Marconi, will make sure that no one will suffer because of your evil!" Serafino yelled as he pulled his right arm back for a punch.

The flames that flickered in Leon's hands grew larger and larger and formed a great longsword to block the strike. The clash of metal on metal reverberated through the forest. Leon's hair began to turn white and black as dark as pitch spread over his skin.

Serafino used his brass knuckle to twist the blade slightly aside to the right as he wound up his left arm for a quick jab. Leon spotted his trick, pulled his sword from Serafino's brass knuckle and parried the other punch, sending Serafino staggering back. Using this opening, Leon used the pommel of his sword to smack Serafino in the side of the head.

Serafino retreated a few steps and put a hand over his bleeding head. "Listen to me! I share the same goal as you. I wish to destroy the demon residing in my body, so please, let's stop fighting," Leon offered with sincerity in his voice.

The features on Serafino grew harder. As he remove his hand from his head, the wound completely regenerated, "I will not listen to a man corrupted by a demon!" he yelled as he sprinted forward once more but reinforcing his legs to make him faster.

Leon was caught off guard by the sudden increase in speed and just managed to move his sword to block the attack. Unfortunately, as soon as he blocked the first punch, another came and hit him straight across the face. Leon staggered, the taste of blood on his lips. "He will not listen to you, so kill him and get this over with!" ordered the demonic voice in his head that was Diablos. Fire gathered around Leon's sword as he brought it down towards Serafino. Serafino blocked with brass knuckles but when he did, a wave of burning hellfire surged from the blade and burned Serafino.

The smell of burnt flesh was rank in the air. Almost every inch of Serafino's skin was a mosaic angry red and burnt black. Leon lunged forward and attacked Serafino but Serafino managed to dodge the attack somehow. Bone plates began growing over his burnt flesh as he regenerated his body.

Leon stabbed forward with his sword sending forth a great torrent of angry red flames at Serafino. Serafino blocked the flames with both arms, charring the bone casing but otherwise, he was unharmed.

"It appears he can adapt to our attacks," Diablos commented

"I figured," Leon whispered back. Abandoning his flames, Leon attack with his longsword. Serafino was forced on the defensive, blocking every strike. Bones shook in his body with every blow as Serafino desperately stood against the onslaught. Every strike pushed Serafino back, until eventually, his back was against a tree.

"Now! Kill him now!" screamed Diablos and Leon was bringing his sword back to make the killing blow.

"I WILL NOT FALL TO YOU!" Serafino announced angrily into the sky. Tentacles with razor sharp bone came out of his back and went straight towards Leon. Leon was completely caught off guard as 4 of them speared him in 4 different places. They whipped him into a tree. Splinters flew everywhere as the tree groaned and collapsed.

With new vigor, Serafino went on the offensive. He punched forward with his right fist and again a sword went up to block. So predictable Serafino thought to himself as he sent forward his tentacles to spear both Leon's head and heart. Luckily for Leon, he managed to dodge the strike and sent forth a another wave of flames that disintegrated the tentacles. Realizing that he needed to kill Serafino swiftly, he arced his sword and prepared to take Serafino's head.

Serafino pulled back for a powerful powerful punch. Both sword and knuckle collided sending out a massive shockwave that blew the leaves off the trees. Cracks began to course along Leon's longsword much to his worry. It shattered. Using this opportunity, Serafino roundhouse kicked Leon in the face, twisting his neck 270 degrees. Leon collapsed onto the ground, lifeless.

"The world is safe from the demon," Serafino said under his breath as he regenerated his torn flesh.

Demonic laughter carried itself throughout the forest. "That's what you think!" Leon's eyes went completely demonic, turning fire red and vertical like on of a lizard. His hair completely white and skin completely black. He somehow managed to get up and snapped his neck back into place with a sickening crack. "I can't believe I have to snap my host's neck back in place in place twice in one week!" Leon complained.

"How could you have survived that! I snapped your neck!" Serafino said with astonishment.

"I am Diablos himself and unfortunately for you, I am quite fond of this host!" The possessed Leon proclaimed. Flames once more formed weapons, this time a one handed greatsword in his right hand and a black pistol in the other. "DIE!" Diablos fired off pistol at Serafino while charging forward with his sword.

Bullets cut through the bone plates, pushing Serafino back. Diablos pulled his sword over left shoulder and made a powerful cut. Serafino used his arms to block, but the swords cut through right through them as if they were nothing at all. Screaming in pain, Serafino retreated back as far as he could until his back was against a cliff wall

"End of the line," Diablos smirked.

"I will not let people suffer because of you!" Serafino's flesh began to boil and warp. 4 biological missiles popped out of the swarming flesh and headed straight towards Diablos. Diablos disintegrated his pistol into the fire and created a massive swarm of fire in his free hand, He punched the ground, sending lava into the sky and destroying the missiles mid air. Letting out a blood curdling cry, more missiles fired out along caustic blood. Diablos tried again with the missiles but one of them made it through and detonated on his arm, blowing it off. Distracted by the missing arm, the caustic blood showered down over Leon, dissolving Diablos and his human host.

K.O. Serafino "Raf" Marconi Wins!

Analysis: Both characters were both powerful with Leon taking the advantage in the beginning but Serafine in the later stages. Even though both characters are smart fighters that analyse each others moves, Serafine was at the advantage in that regard. Leon's powers are consistent and have a set pattern while Serafine was almost completely unpredictable for someone who has never faced him before. Serafine was also able to analyse much more easily and use it to his advantage much better than Leon could. The only thing Leon could take out of the battle is that Serafine can adapt to attacks which means every blow must be a killing one if he is to win. Unfortunately, pursuing such a tactic left him open to counter attack. There is also the fact Serafine gets more powerful the more stressed he is and facing the most evil and powerful demon in existence is extremely stressful making him utilize his most powerful abilities. But even with Diablos possessing Leon at the end, he is not at his full power and must use his human host and biological missiles and caustic blood is almost impossible to predict. If Leon were to press his advantage in the beginning he would have won easily but he didn't as he thinks they both have the same ultimate goal. They put up a good fight but Serafine's unpredictable powers made him end up on top.

Bio 1

Name: Leon Blaze

Age: 18

Gender: Male

Species: Demon

Appearance: Has black curly hair, brown eyes, and tanned when in human form. When in his demon form his skin turns pitch black, his hair turns white, and his eyes go red. As for clothes he likes to wear a black jacket, a white undershirt, and dark blue jeans. He'll normally wear gloves and boots as well. On his neck is a chained necklace of a symbol resembling a dragon's head. A white mark reflects on his upper left shoulder, showing he is the host of the demon Diablos.

Personality: Leon is brave and persistent

History: Has the original demon Diablos sealed in his body the day he was born. Became the first demon in history to fight alongside the angel against a destiny of endless hate and war.

Arsenal: Can summon two swords, one just a longsword while the other is a greatsword. A pistol can also be formed from his flames

Abilities:

Power 1: Can release fire from his body as an attack and a defense. For example he can power the flames to a specific body part (lets say his fist for this) and smash it into the ground causing craters of lava to erupt from the ground. Leon can also use his flames with his weapons by causing them to blast out when he swings his sword or when he fires the pistol.

Power 2: Has the ability to adapt to a different opponents fighting style. If the opponent fights in a way Leon has never encountered before, he will slowly begin to learn more about him as he continues to challenge him. Eventually Leon will find a way to defeat the enemy and completely destroy them.

Fighting Style: Leon tends to fight smartly, utilizing his powers to fight. Though he mainly uses his flames and swords, he will rely on the pistol if he needs to close the distance or hit a small target accurately. The demon sealed in his body gives him his strength making him an incredibly dangerous opponent to any foe.

Bio 2

Name: Serafino "Raf" Marconi

Age: 17

Gender: Male

Species: Noble (a person freed from his fate and given supernatural powers)

Appearance: Thin, a bit taller than others his age, he has longish brown hair that come up to his shoulders, with bangs that cover one of his large, slightly slanted green eyes, which are perpetually plagued by intense dark circles.

Personality: reserved, a bit of a loner, but also headstrong when the situation requires it and playful with the few people he can call his true friends. He is prone to intense mood swings that can last anywhere from a few hours to a few months, and has had periods of severe depression, because of this he absolutely hates seeing people suffer and being lonely.

History: Heir to a rich family of real estate investors, he saw his father killed by a madman with a pickaxe in front of his own eyes when he was only seven and that severely traumatized him. When his mother was diagnosed with terminal breast cancer and died soon after, he couldn't take it and tried to off himself by throwing himself off a bridge, however, he managed to survive with the help off a strange paranormal presence and woke up from a coma around one year later with his abilities and a promise of freedom from fate's despotic rule. He soon after moved to Tokyo and is now dealing with the complex Noble community of the sprawling metropolis.

Arsenal: his own body, reinforced, steel tipped boots and brass knuckles.

Armor: Due to his overconfidence in his power, he rarely wears any sort of armor

Abilities: Body Modification. [Mid-Low LvL] [He can enhance his body and regenerate by growing and substituting new tissues, organs and appendages to the old. He generally uses this power to simply enhance his strength, durability and speed, because more complex and radical transformations require a proportional level of stimuli (felling cornered in a fight is a big one, but so is the will to protect that which is important to him etc.). When cornered, he begins to grow bone armor and fleshy, sharp tipped tentacles around his body, becoming capable of pressing up to 30 metric tons and sprinting like a F1 car.]

Body Modification [High-Supreme Level] When feeling very strong emotion and finding himself in the right state of mind, Serafino can assume the form of a truly nightmarish beast with strength, agility, and durability beyond your wildest dreams while still keeping sane and in control of his actions. What is scariest of this level of his ability is that he can grow completely new organs that function as biological weapons (i.e. emitting toxic gas clouds, high pressure caustic blood streams that cut through concrete, explosive missile like projectiles or even high powered radioactive lasers)

Brain Manipulation: Like he can manipulate the structure of his body, Serafino can also mod his brain and nervous system to achieve feats like enhanced reflexes, heightened senses, learning ability and tactical thinking, to the point that, even when relaxed, he can see the world moving at about one third of the normal speed. This power scales like body modification does.

Fighting Style: He is an able street fighter, but a honest one, who frowns upon dirty fighting tactics. When transformed, he capably uses all the resources at his disposal, moving like a whirlwind of destruction upon the field of battle and preferring multiple low-powered quick attacks for most opponents. He also has a heightened "tactical decision sense" that only gets better and better as he gets into disadvantageous positions in a fight, allowing him to find a workaround or a weakpoint in most opponents fighting styles and powers, given time.
