Prologue

It was May 15, 1989 in Derry,Maine. The suns rays shined brightest on the tall pine trees from the park to the lush green grass on the neighborhood lawns. It was a lovely day for a walk in the park, go for a jog with a friend, or ride a bike to a popular arcade, but underneath Derry lies the empty sewer tunnels with no life whatsoever. The sewer tunnels carried the unpleasant odors of sewage and garbage, but on top of all that lies a dangerous creature with a taste of fear. In the the dark, gloomy tunnels, a clown walks slowly with a small bag to a secret room in the chambers. The bag contained a small child tied up and gagged, but you could hear the muffled screams and crying from it. The clown walked towards a steel door and made his way inside. In the room was a old, beaten clown that looked like he lost a fight with some mob dealers and was close to the break of death. The clown opened the bag and picked up a 9 year old boy and placed him on a laboratory-like table with sharp knives and a small cup. The boy had light brown hair, blue eyes, wore a maroon shirt with white stripes, long jeans, white sneakers and was covered in mud and grass stains from yesterday's rain. The clown picked up a small blade knife and made his way towards the boy. The boy flinched in pain as the clown made a small cut on the boy's cheek. As blood started dripping from his cheek, the clown picked up the small cup and a small tablespoon and started to placing the blood in the teaspoon towards the small cup. The blood eventually stopped dripping and the small cup showed enough blood. The clown picked up a teaspoon and made his way towards the old, beaten clown.

"Father I have the blood of a pure child. This should heal the broken bones." The clown spoke.

The old clown looked at his son. The small cup was completely filled with the boy's blood. Not a lot to kill him, but it was a lot to perhaps make him weak. He got up a bit and looked over at the table. The boy was fine, except he had a small cut on his cheek and he was crying. The old clown laid back down and the clown started giving him a spoonful of the child's blood. The old clown started to take it spoonful after spoonful. After the cup was empty, the old clown laid back down and waited for the effects to take in. The clown held his father's hand tightly with a sad and concerned look.

"How are you feeling father?" he asked.

"Honestly Pennywise, I don't know if I have the strength to move or hunt for children's fears anymore." the old clown rasped.

He dazed off sadly for a few moments, than it changed to a angry snarl without looking at Pennywise.

"But soon you'll need to get the ones that did this to me." the old clown sneered.

"Oh trust me father they won't get away with this." Pennywise growled.

However, because it occurred in 1962, the likely chance of the 8 people responsible for his father's injuries made it a 5% chance that they were still alive making Pennywise have his doubts. Plus there would be a few problems if he ever did get them.

"But dad there's one problem. It's been 27 years since your attack, we don't necessarily know if they're still alive and how will I get them? Adult minds are stronger than children's minds." he pointed out.

Pennywise had a point. For as long as these two could remember or at least for the old clown, they never possessed adults due to their minds being stronger than a child's and had less fear in them. The last time the old clown possessed an adult, it fought back and there was less fear in him for the old clown to take. But the 8 people were young adults back in 1962, by now they would be old or dead. Suddenly, a memory sparked in the old clown; one that would be an advantage to Pennywise and himself.

"Pennywise, Billy had a son that was 15 years old at the time. If we're lucky, he could have children of his own by now." he spoke.

Pennywise thought about that. He headed towards a brick wall and grabbed a loose brick to retrieve a book. Inside the book contained family trees of every person in Derry. Pennywise searched through the pages until he saw the page he was looking for. Fortunately, each of the eight people did have grandchildren. Unfortunately, two of the 8 people were still alive. This would mean that they would only kill two of the eight people and that wasn't enough for Pennywise or his father. Frustration took a toll on him as Pennywise looked at the boy he had captured than at his father.

"Dad I have good news and bad news. Which one do you want to hear?" he asked.

"Bad news first. The good news second." the old clown answered.

"Alright, well the bad news is that only 2 of the eight people are still alive. The good news is that each of the eight people have grandchildren." Pennywise spoke.

"You know Pennywise we can work with that. We possess children right? Well what if we use the grandchildren to do our dirty work, than we can go after the grandparents." the old clown maliciously spoke.

"Excellent idea father! Not only will we be able to get some kid's fears and sinner's blood, we'll kill their grandparents as well. Its perfect!" he smirked.

Pennywise and the old clown turned to see the boy had stopped shaking and crying, but was casually listening in on their little conversation. They knew that if they let the boy go, he'll possibly tell the cops or their intended victims. Pennywise looked at his father with the same idea he had. He got up and approached the small boy.

"You know father, it would be a shame to let Henry go so quickly, but what we can do is kill him." Pennywise said evilly.

Henry started shaking and crying again when he said that and Pennywise removed his glove to reveal a demonic werewolf-like hand with sharp claws. He removed the blindfold off of Henry to let him see his captors. His eyes widened with terror as Henry saw that his captors were clowns, but not just any clowns, demonic clowns.

"Henry do you know what my hand can do to little kids?" Pennywise asked coldly.

He shook his head while shaking and crying. Pennywise removed the gag from Henry's mouth and he started to breath heavily.

"P-P-Please I wanna go home to my family." he stammered.

"Oh no you're not Henry. If I know that kind of pleading a child would make, it would be the kind of plead to trick your captors." Pennywise snarled.

"PLEASE! I won't tell anyone your plan I promise just please don't hurt me!" Henry pleaded.

"Oh i'm not going to hurt you, but I am going to do this..." Pennywise sneered.

He raised his demonic hand and behind Henry was a ghostly demonic hand with razor sharp claws. It struck him; digging through his shirt and deeper on his back. Electric volts shocked Henry; causing him to scream in agony and in pain. The more he tried to resist, the more impossible it seemed. Soon Henry was getting weaker and weaker by the minute, the spell was just too strong for one nine year old's mind to resist then his eyes closed. Pennywise smirked at the revelation and placed his hand on the side of Henry's head. He leaned in to his ear.

"From now on you will obey my every command. Your will is no longer yours; it is mine. Do you understand?" Pennywise demand.

"Yes...I will...obey."Henry muttered.

After a few moments, he opened his eyes to reveal demonic white eyes and a expressionless look.

"What is your command master?" Henry asked.

Pennywise grinned evilly and released Henry from the ropes. He picked him up and placed him down gently on the hard stone ground.

"You must find me the Denbrough family. When you see their youngest child, report to me at once. Do you understand?" Pennywise ordered.

Henry nodded.

"Your wish is my command master." he replied.

He turned and left the room closing the steel door on the way out. The old clown looked at Pennywise.

"Pennywise how long are you going to keep Henry like this?" he asked

"I'll keep him like this until we get every last grand child of those brutes. Besides Henry will be useful for me. For now at least." Pennywise spoke.

He looked at the book again one last time.

"I'm coming for you starting with the Denbrough family". Pennywise snarled.

Ok so a few things about this story is this:

1. Mike, Beverly, and Ben already know Bill, Georgie, Eddie, Stanley, and Richie in the beginning of this AU

2. There are two Henry's, but Henry Bowers will only be referenced as Bower's in this AU

3. There will be certain characters mentioned or are a part of it from the IT 1990 and characters from To Kill A Mockingbird. However, the story is a short crossover and the Kill a Mocking Bird characters will only be in the story for just one time.

4. I DO NOT own IT or any of the other characters in this story. Just Henry, "my demon" and Mia.
