Twisted By Hell

Summary: The backlash from the greatest invention's caused Tadashi soul to be accidentally sent to hell and be mistaken for a seedling. Living in hell for a year twisted his mind beyond repair and became unrecognisable when he is summoned by a man who wants revenge for his daughter death.

I do not own Big Hero 6.

Enjoy!

"TADASHI!"

That was all he heard before the massive explosion, and the feeling of nothing but intense heat hit him.

Suddenly that feeling went away, and he felt a floating sensation.

He was dead.

He looked down and saw that he was naked, but instead of going up, he found himself going down.

Only one place was down below when you die.

"Wait. This is some kind of mistake!" Tadashi said, he had never seriously done a bad thing in his life, and he tried his best to be a good person.

But nobody was around to correct the mistake, so he went down below, and down through the multiple layers of earth, he went passed the earth's core before the world began to spin around him and he was suddenly waking up to horrific screams.

"AAAAaaaahhhh"

"HELP ME! HELP ME!"

Tadashi couldn't move, but he didn't need to move his head to take in the vision of what could only be called Hell right in front of him, inhuman looking creatures with horns were everywhere, souls were small, and each face was twisted in pain moved around the environment in groups.

Fire rose from the ground and raged as if it was alive.

The very image was nightmare inducing.

Suddenly Tadashi felt his shin being lifted up and he saw a child that would have looked human if not for the giant round horns on his head, devil wings and a black and tail sticking out of him, the child's nails was unnaturally sharp.

"So, this is a seedling" Said, the child as Tadashi could do nothing. "Let's call you Hellfire. I was never good with names."

Suddenly Tadashi felt something rip from the flash out of his back and out came large demon wing's, on his head grow demon horns, his fingernails began to sharpen and out came a Devil Tail.

"Who knew being giving a name would grant such a change? Now, it's time to give you, your first meal" Said, the 'child.'

Suddenly the sound of horrific screams where much closer than ever and Tadashi mouth was forced open.

He didn't have time to fully comprehend the scene in front of him when a wave of souls flew right in his mouth.

They were the souls of the damned.

Suddenly Tadashi, got a front row seat to what all those souls flying into mouth had done to land themselves into Hell, while they alive.

What he saw was so horrific, that somebody could have easily vomited.

But that horror quickly turned to flavour.

The most fantastic thing he had ever tasted suddenly burst out of the souls he consumed, and he didn't even know it was over because his body moved and went to look for more not satisfied with what it had been given.

He ran to a lake full of screaming souls and sucked it like he was eating noodles, he sucked them until his mind came back and he pulled out of the lake in horror.

W-What did he just do?

"Congratulations" Said, the 'child'. "You are now a full demon."

"D-Demon?" Tadashi said, before saying. "There's been a mistake I'm not a-"

"You're not going to say that you're in hell by mistake?" Said, the 'child' suddenly his face went completely blank. "When a soul ends up here, they don't have the appearance of their original body. Do you realise how rear that is in hell?" and then suddenly the child showed sharp teeth and started drooling like an animal.

And Tadashi knew right there and then; that this 'child' would eat him in a second and make it the most horrific experience of his life.

Tadashi survival instincts kick in, and he said. "Of course not. I'm a demon, all soul's need to be consumed."

Tadashi hoped that was what the 'child' needed to hear.

Thankfully it was.

"Well, that's a shame" Said, the 'child', before spreading opened his wing's. "Well, then Hellfire. Wonder around Hell and consume souls. Devil-sama just gives us the job to torture the soul's and consume. It's a very luxurious existence."

Luxurious?

Tadashi wanted out.

The 'child' flew away and went to join a group of demons as they danced around a cauldron of soul's who were being boiled at a perfect temperature to torture them with.

Tadashi tried to look for a way out of Hell, but all he found out was, a fresh demon couldn't get into the human world unless they've been summoned.

And that could take thousands of years.

Tadashi was stuck in hell, never to see his family and friends again.

But his horrific experience was nowhere near over; he soon learned that if his body didn't consume a soul after a period, then it would force him too.

There was no 'No' with his body and Tadashi was forced to see horrific memory after horrific memory with barely any breaks.

He saw a child slaughter his own family.

He saw two brothers' torn apart by greed.

He saw people go on a murderous rampage.

He saw people deceive other people and suck them dry until the person saw no choice but to commit suicide but they didn't even blink.

It was horrific, and his faith in humanity was shaken with so many memories dancing around in his head before settling into his stomach.

One month, past and he consumed, he was starting to change.

He had built up some kind of resistance to the horrific memories and was a lot less affected by the 'tame' ones.

Two months.

Three months.

Four months.

Tadashi emotions began to dilute, the memories no longer had any effect on him, and he could focus entirely on the taste.

He found out that the more terrible a person is, the more delicious they tasted.

When a person did something terrible for a good reason, their soul tasted disgusting.

There was nobody or nothing to keep him grounded, and he began to referrer himself as a demon.

What was the emotion called Love?

He was no longer sure anymore.

Was the love he had for Hiro, the same love where he would stab him in the back if his brother wanted to leave him?

His definition of love was warped by the memorizes and he found that he enjoyed soul-sucking.

A lot.

The big-hearted guy named Tadashi Hamada was gone.

In his place was the demon called Hellfire.

Hellfire opened the doors to a bar and walked right in; he wore a fancy jacket and pants that he had stolen from another demon when that demon wasn't looking.

Hellfire did not blink at the horrific creatures inside in the building as he made his way to the counter, that had a two-headed creature for a bartender.

"What can I get up?" Said, the monster.

"Give me your finest glass of Damned Wine" Hellfire said.

"Coming right up" Said, the monster, before going to the back and coming back with a glass that contained a green liquid in it and within it were screaming souls, looking for a way out.

Hellfire grabbed the glass and without hesitation began to take a sip.

"So, this is the best Damned Wine in all of Hell? Fantastic." He said, before smiling cruelly. "It was well worth the trip here."

Just then a bright light shone where his seat was, and he looked down to see a circle he had become familiar with in the year since he arrived in hell.

It was a summoning cycle.

An idiot human was summoning him.

Hellfire took a big gulp before he disappeared.

#Human World#

He blinked and saw a darkly lit room with candles.

It had been so long since he hadn't heard the roar of flames or the screams of doomed souls, he did not know what to make of it.

Who was the human who summoned him?

Finally, the human decided to step forward; it was a man he would recognise in a second.

It was his old professor.

Professor Robert Callaghan.

So, he became a demon, and the bastard survived?

This was an entertaining story.

"T-Tadashi?" The man said, surprised.

Tadashi?

He hadn't been called that name in a long time.

"If I was a human do you think I would be summoned, human?" Hellfire said, he wasn't Tadashi.

Tadashi was dead.

The man looked stunned.

The face and voice were identical, but there was something seriously wrong with the tone of his voice, and the look in his eyes was as if his very existence was amusing to him.

Was the demon trying to pressure him?

"My name is Hellfire, a demon of Hell" Hellfire introduced himself as well, "You wish for revenge against the man who killed your daughter."

"H-How did you?" The man said.

"I'm a demon. I can smell the desire on you" Hellfire said. "And I will be more than happy to help you, after all, it might be fun." before he said with a slow predatory smile. "But of course...you should know my services aren't free."

For a moment there, there was terror on the man's face; it was clear to him that the man hadn't truly realised what a Demon was like when summoned.

Just standing in front of one made him feel like he was staring at a lion that hadn't eaten in days.

But the man's resolve was firm and said. "You want my soul, correct? Take it. I've been dead for years without justice for my daughter. All I want is revenge."

And Hellfire smile widened as he said. "Your desire is pretty strong, old man. I can tell, I'm going to have a lot of fun fulfilling your request. So, let's sign the papers right away. What kind of bond do you want us to share? A Master and Slave one or Full-fledged one."

"What's a full-fledged one?" Callagham said.

"It's a contract that says I can do whatever I want as long as I fulfil the request that I was summoned for," Hellfire said, startling the man.

The image of a demon raining hell down on all of San Fransokyo was not an image that a decent person wanted to see.

And thankfully, Callagham wasn't that far gone.

Yet.

"I think a Master and Slave contract is best," Callaghan said.

"And here I thought I was going to stretch my wing's out in the human world," Hellfire said, with a tone of disappointment.

And then a floating penchant appeared in front of the man much to the man own's surprise and a quill, but there was no ink.

Hellfire was suddenly at the man side, much to his surprise and floating.

"Prick your finger onto the quill. It won't work if this isn't a blood signature" He said, and the man reluctantly did so and felt a massive amount of pain came from it.

Everything from hell was made to be extremely painful to a human.

"Sign where I point," He said, as the pain dripped with the man blood, for the first time the man saw his abnormally sharp fingernails on full view.

He began to sign where Hellfire pointed at and when he was finished, the penchant and quill disappeared and the wound on his finger healed right up.

Callagham looked stunned but then on his hand appeared a weird symbol on it and on Hellfire neck was the same symbol.

Suddenly the smug demon got down on one knee in a bow and said. "Master, how may I serve you?"

The man was understandably stunned.

Master?

He had just become the master of a disaster level weapon.

But Callaghan wasn't willing to get drunk off the power just yet.

"What did I just sign?" Callagham said, cautiously.

"Master, you bound me to follow your orders, and I will receive punishment if I go against your will" He answered obediently.

The man was stunned before he said. "You'll do anything I want?"

"As long as it is in line with your desire, then I am bound to obey," Hellfire said, further stunning the man.

The man looked at him, feeling awkward before saying. "As you already know, I am considered dead to the world. I cannot go outside, so I need somebody to collect everything I need."

The man handed him quite a list, and Hellfire mind realised it was the parts that made up a duplication machine.

But he was not permitted to find out what the man, planned to duplicate.

"I would like you to go out and gets these" Said, Callaghan before the man seemed to realise something and said. "I would also like you to wear this mask. You will go under the name 'Yokai'" giving him a strange looking mask. "And do not kill anybody. Just the target."

Oh?

There was quite a bit of darkness in the old man's heart.

"As you wish, Master" Hellfire said, taking the mask and putting it on his face.

Then he disappeared.

He reappeared in front of a factory and looked at the first item on the list before approaching.

"Hey, who goes there?" Said, a security shining a light on him.

His response was.

"Just somebody passing by on a Shopping trip."

His answer stunned the man.

There was no killing, right?

That was just no fun.

And scene!
