I got the idea of this kind of story from Something Grim This Way Comes By: Ruskbyte But this story will turn out completely different then the three first chapters (That's how many are posted at moment so yeah…) How you may ask… well for one Mandy- Nope no spoilers but just beware something tragic will happen within this first chapter!
DISCLAIMER: I do not own Harry Potter OR the Grim Adventures of Billy and Mandy.
Chapter One: Harry's Childhood. Starting at age 6 and a half.
Harry sat on the swing looking down. Hearing a familiar laughing he jumped out of the swing and after stumbling slight started to run. It was to no use though as they caught up to him. His cousin smirked and was about to punch him when a cold monotone voice said "I wouldn't do that if I were you."
Dudley sneered at the girl with blonde hair and a pink dress and said "What you going to do about it girly?"
Her eyes narrowed and she said in that cold voice of hers, "I'm going to kick you."
Whether it was because of her cold voice or her glare Dudley whimpered and he backed away as did the rest of his fellow friends. The girl walked over to Harry and held out her hand "I'm Mandy"
Harry nodded in greeting and quietly whispered "I'm Harry" her gaze stayed on him for a few more seconds before she said "You'll do, come" in a commanding tone. He gulped and followed Mandy.
Soon they were walking along pivot drive and right across from his house they stopped at Number 16 pivot drive. "This is my house" Mandy stated.
"The house I live in is right across the street" Harry said pointing to Number four. Mandy nodded and tilting her head said "I want you to meet my… friend."
"Friend?" Harry questioned quietly.
"Yes come in" Mandy said so shrugging to himself Harry followed. Mandy closed the door behind him and then she called out "Grim! Get your boney self down here before I come to you!"
Harry heard a grouchy Jamaican voice call down "I'm coming! I'm coming!" soon he heard footsteps and saw a guy in black robes holding a scythe at least he assumed it was a guy until he saw the persons face.
It wasn't really a person, it was the Grim Reaper. "Friend?" Harry once again questioned looking at Mandy confused.
A smirk came onto her face and Grim looked mildly disturbed as he grumbled "Stupid bet" under his breath.
"Grim came to take the life of my friend's hamster, I made a bet with him, I won" Mandy said.
"And now I have to be her friend forever until she dies!" Grim whined.
Harry blinked then shrugged and asked "Why did yeah move here?"
Mandy smirked again and said "I moved here for a few reasons the most important one is I was kicked out of Endsville and I always wanted to come to Britain."
Harry nodded and then looked at Grim "So don't you kill people?"
"Yes when this brat here allows me too"
"But people are still dying even though you're not working why?" Harry questioned too curious for his own good.
Grim gave a laugh and said "That's cause theirs more than one Grim Reaper you see I'm the third most powerful Death entity, the only one more powerful than me is Death and the Devil himself. There are a few ranks below me that do most of the trivial work allowing me Death and a couple others to have fun with our powers"
Mandy raised an eyebrow and said "Is there any way to control Death?"
Grim narrowed his eyes a bit then sighed and said "Yes, by the three Hallows, and… if I'm reading this right then you Harry, already own two of them."
"Wait! What?" Harry exclaimed shocked.
"Yes… the cloak and the wand."
"Cloak?! Wand?! What are you talking about!" Harry exclaimed confused.
So then Grim explained the tale of the brothers and about witches and wizards and how he used his knowledge of knowing everything to fill him in on his parents the cause they were fighting for and what they were fighting against and how the Dark's side goals were good it's just that Voldemort became insane. Grim also stated how Voldemort was alive.
"I want you to make me a witch, and then I want you to train us." Mandy command Grim.
Grim did just that for the next few Mandy and Harry became close friends and they even had a few adventures together like Billy and Mandy had though these were in no way Harry's fault unlike the adventures with Billy.
On his ninth birthday Mandy said "Grim if I die before Harry He will replace me as your owner" Grim sighed and nodded. Harry blinked at his friend confused and she said "It's your birthday present" So Harry nodded and they went on with their life.
Harry disliked muggles ever since he learned he was a wizard, mostly because of the way they treated him, Grim, and Mandy cause they were different, but he didn't want to kill most of them except for his family though he would wait to get his revenge on them. That was until a certain incident.
It was his Birthday he was finally going to turn ten he smiled at Mandy before closing off his expression with a frown it was something he learned from Mandy she taught him how to intimidate people so he wasn't picked on. Because of this Mandy allowed them to be more open with each other as long as they were alone.
They were going to a big outing both Mandy's family and the Dursleys. Plus a couple of Dudley's friends. Grim would be coming as well he would just be invisible to everyone but Harry and Mandy.
They would be going to a nearby town of Little Hangleton. They went into the vehicles and took a drive their. This wasn't anything unusual and it wasn't some kind of birthday present, certainly not but Harry pretended it was no this trip was for one of Dudley's friends. The Dursleys had so kindly offered to take Pier's to this town for a special movie. Of course once Mandy heard she forced the Dursleys into letting Harry and her family join them on their outing.
Throughout the car ride Vernon glared at Harry and Mandy hate was in that gaze as was fear. Finally arriving at the movie theater, they went to watch the movie. About Halfway through Mandy said "Let's go this movie is lame" and Harry nodded.
They got up and left the theater, Grim staying behind. Mandy walked ahead of Harry and so he followed his older friend out of the building.
Mandy smirked and said "In one year we will be going off to Hogwarts"
"When will you have Grim make the ring?"
"When we first get our letters we can't have the People know we control Grim though." Mandy said smirking.
Harry chuckled and said "Yeah he is our trump card after all" Harry smiled at Mandy and said "I'll be right back I'm going to go find something to drink do you want anything?" Mandy shook her head and Harry went in while she waited outside.
It was then that it happened. Harry didn't know what happened exactly but he had only been in the store for a few moments when he heard a scream that sounded familiar it sounded like Mandy! "STOP! PLEASE!" he heard her begging as he got closer to an alley and heard a sickening sound.
Harry could hear the satisfaction and superiority of the man's voice when he said "Thanks for that girl" and then there was a loud bang. Harry ran forward and saw the man a sickly looking fellow. With stringy black hair and a sunken in face the man smiled cruelly at Harry and then said "Your girlfriend was a pretty good fuck"
Harry's eyes widen and he runs past the man as he realized what he had done the Muggle had- had raped Mandy! Harry went to her body and grabbed her "Mandy! Oh Merlin please no!" he begged and in that moment he stopped disliking muggles no now he hated them they took away Mandy, and he promised himself He would make them pay starting with Mandy's murderer.
No matter how much he begged though he couldn't change the fact that Mandy was dead. Harry sobbed as he clutched Mandy closer to him unbelieving. "Grim!" Harry yelled and The Reaper appeared and angry look on his face until he spotted Mandy.
"Who did this to her!" Grim demanded outraged fire in his eyes. "A muggle! He raped her Grim and then he shot her!" Harry said "He looked sick and had black hair." Grim nodded and then flew up and away.
Harry was still sobbing over her body when the police came. They took him away and asked tones of questions and gave a few answers such as the name of Mandy's murderer "His name is Jacob Granger."
Harry left the place and found Grim standing outside a grim expression on his face. "Why?" Harry whispered "Why Mandy? Why not someone else?!"
Grim looked at Harry and said "I couldn't find the man he ran away from this area!"
"Grim don't be a muggle" Harry said in a way that painfully reminded them of when Mandy would say "Don't be a bonehead"
"Oh yeah" he said sighing eyes filled with tears. "Grab on" Harry grabbed Grim's arm and he slashed his scythe opening a portal. They stepped through and came face to face with Jacob who couldn't see Grim. Harry glared at the man "You killed Mandy" Harry accused. "Grim give me your scythe I'm going to kill him" Harry said in a deadly voice.
Grim just handed his scythe over and as Jacob pulled the trigger of his gun Harry swinged the scythe deflecting the bullet. The ten year old walked forward and fury in his eyes he swinged chopping the man's head of.
Harry nodded his head and whispered "Justice has been done Mandy."
The next year passed slowly the first month was spent grieving then a hollowness replaced it after another month all that was left was a hallow feeling and a hatred towards the pathetic filthy muggles.
The rest was spent training. Harry finally had Grim tell him how to summon the cloak and the wand so he could use them.
It was Dudley's birthday and he decided he wanted to go to little Hangleton's Zoo Harry sat stoic face the entire ride and decided to find a place where he could avoid everyone until it was time to go.
He got out and walked around before finding a small shack he entered it and explored while Grim decided to go do a bit of reaping. Harry soon found a ring that called to him Harry looked at the ring and heard a faint hissy voice say §Come put me on muggle and meet your doom!§
Harry glared and hissed at the ring §How dare you call me a muggle you piece of jewelry!§
§You ssspeak! Put me on fellow ssspeaker I ssshall not let harm come to a brethren!§
Harry smirked and then hissed out §If you do I ssshall have my ssserveant the Grim Reaper dessstroy you§
With that Harry picked up the ring and put it on. After a few minutes with nothing happening Harry nodded his head and walked out of the building only to come face to face with a guy with black hair that was slightly spiky who wore a leather jacket and a pair of jeans.
"Well well looks like you found the stone" the black eyed man said smirking.
Harry leveled his gaze at the man and asked "Who are you?" the man smirked and said "I am now your servant master as he have conquered all three of the Hallows. I am Death"
Grim decided at that moment to make an appearance "Harry it's almost-"then he spotted Death. Grim seemed to pause for the briefest of seconds then looked between the two.
"Harry?" he questioned after a minute of silence had befallen.
"I apparently found the third Hallow" Harry stated calmly yet a hint of surprise could still be heard.
"Now you have to powerful servants" Death said smirking.
Grim said "Mandy would be proud of you Harry."
"Mandy Maxwell?" Death asked curious.
"Yeah" the duo replied at the same time looking guarded.
"That girl is evil!" Death said shuddering.
Grim and Harry exchange smiles and Harry states "That's our Mandy still terrorizing people even in death"
"Yeah well some of the residents of the underworld are trying to talk her into becoming a ghost"
They spent the rest of the time learning about Death and stuff that happening in the underworld apparently the Devil had a son with Life and the child was kidnapped. Apparently Harry kind of looked like their kid except his eyes were green and his hair was a lighter black.
Death turned into a black cat and then said "I'll be your familiar Master" Harry frowned then asked "I hear you mewling like a cat but I can understand you?"
The cat grinned a Cheshire smile and said pompously "Death speaks all languages."
Harry blinked "Does that mean I speak all languages?"
"Correct." Death stated.
The new trio went back to the house and Harry returned to his bedroom, Dudley's old toy room, in which he had moved in because of Mandy and Grim who helped to scare the pathetic muggles.
