I do not own Harry Potter and The Green Lantern serie, this is fan fiction only
Harry Potter could only be described as a truly miserable person, having been made an orphan by a psychopath that called himself Lord Voldemort was bad enough but being placed in the care of his aunt Petunia Gaunt and her husband Vernon Dursley was possibly even worse.
The couple hated Harry the minute he was left in front of their home. They made no problem effort to comforting a crying baby and as he grew up he realized the awful truth, if they made any effort on his behalf it was to kill him. The poison in the milk bottles could still be sensed even after they had been washed and put in the attic.
The couple looked for any reason or opportunity to inflict pain and possibly life threatening injury upon him. They under feed him and gave him the most unsanitary place in the house to be his cell, oh, I mean his bedroom.
It was during one night that he was soaked in cold water and left out in the backyard during one particularly cold winter night that something strange happened. A large green Lantern came crashing out of the sky and on the handle was a ring. The ring made the Lantern flash and as soon as it stopped the ring flew and attached itself on Harry's broken and bleeding hand.
The ring began to glow and his many wounds and scars began to heal. Since then he asked the ring to hide the Lantern and itself, or else the mean people in the house would try and take it away from him to sell it and buy his ever fat cousin a new toy, just to cause him pain.
The ring did as Harry asked. The Lantern hid as a small piercing inside him. It just clipped itself on a rib right over his heart. From that moment he began to talk alone, it was a good sign for Vernon since he could be sent to a mental institution, people often died in those.
For some strange reason the ring did not do as it was supposed to do, it was supposed to have him say the oath and bring the new Lantern back to the home of the Lantern Corp. The ring instead took time and began to teach him things in his sleep. He began to teach him a out martial arts and forms of combat, it seems the previous Lantern who wore this ring was an expert.
As the years went by his mastery of the combat forms and light constructs became more advanced, so much so that he began to look for strange items that held the soul of an evil man. The man who murdered his parents and condemned him to his current hellish existence with the Dursleys.
He found out that they were actually items worn by people and those people were all over London. The biggest surprise was that himself had one of these pieces of the evil man's soul. The ring was quite good at extracting the piece and with a blast of green energy he assimilated all the knowledge from the soul fragment causing it to be destroyed.
That was at the age of seven he learned the truth of his parents death and it was as he suspected they had indeed been murdered but they were not the penniless losers that Petunia and Vernon said they were. They were a wizard and a witch, and his ever mean Aunt was the worst of their kind, a squib. That explained the jealousy he heard in her voice whenever she talked about his parents.
It was during his eleventh year he was invited to attend Hogwarts and he was smart enough to take the letter before Vernon had a chance to realize it had arrived. Using his ring he made decent travel clothes and he decided to get ready to attend. Should his aunt and uncle interfere they would regret it.
The goblins were friendly enough and the back manager was actually as happy as can be that he had come to get some money from his vault. The old goblin explained that explaining the ever growing amount of gold was becoming a rather frustrating task and he needed to have his authorization to have his family vault expanded.
Unlike muggle banks, goblin banks offered good interest rates to the people that deposited and kept accounts this was even more for families that were considered ancient and Noble. Harry was recognized by a blood test to being the heir of not one but three houses. Harry was the air of House Potter, Gaunt and Slytherin. He was a major investor for the bank and owned half of the daily prophet.
This recognized level of wealth and influence made him be so important to the goblin nation, that their king assigned the bank manager to look after his account and if he should ever fail to provide good service to Harry or his descendants it would cost him his life.
The wandmaker Ollivander was besides himself he simply could not find a single wand that would accept him. He tried every single wand he owned and in his entire store he simple could not find a single wand for him. It was something that never once happened to him in decades of making and providing witches and wizards their wands.
Seeing that this was an unprecedented occasion he decided to apologize to Harry in the only way his family ever could. His family was a long line of masters of wandless magic. So he did the only thing he could do, he did the spell that would copy all of his own skill with wandless magic to him. It was a spell he would have done for his own children only.
Ollivander knew that he was not going to be a parent and that his long family line was going to end with him. He hoped that the young man before him, who he could not find a wand for would one day out his family knowledge to good use. That alone would be enough to make the old man happy.
He bought a whole lot of things he would need and he stored them in a pocket dimension. When the day finally came and he was ready to leave Vernon stood and blocked his path. "Where do you think you are going your freak? I still have things for you to do." Vernon was not only not a kind man it seems he was not that smart.
Harry walked up to him and while faking a punch his ring made a giant spiked gauntlet actually punch him knocking him out. He then was carried by his neck to where Petunia and Dudley were. "Aunt Petunia I know the truth and I know what you are. This will be the last you ever see me and the last time you thieves get to steal from my family vault. Have a good time in Azkaban where I hope you end up as a dementor's bitch."
Aunt Petunia knew that he was not kidding around. She felled to her knees and begged him not to send them to prison. That he should show mercy to them for taking care of him for so long. "Not a chance, I will never let evil people prosper or go free. Good luck with the locks and if you try to use your car it will not start. The authorities will be here in about ten seconds. I would stay and watch but I have a train to catch."
Harry saw Dudley look almost scared half to death as he left and with a blast from his ring the door and all windows were nailed shut. He heard his aunt scream that he should have died before bringing ruin to her family.
The Aurora showed up just as he said they would, and they took a statement, the that he was provided by the bank manager and a few dozen bottles of memories of his most horrible time with the Dursleys. Amelia Bones thanked Harry for keeping the criminals from escaping. "It's the very least I can do for a fellow officer of the law."
Harry got on board the their in the well hidden platform of 9 and 3/4. He took a quite compartment where he spent meditating as he began to float in mid air.
On the other side of the Galaxy on the Planet Oa several guardians were not happy with how the situation with the missing ring battery of one of their most respected Green Lanterss simply disappeared without a trace. The battery and ring of Abin Sur went missing over a decade hand no one had a clue as to where it had vanished.
Sinestro could only get the feeling that the ring and battery had actually chosen their next Lantern, he could not tell the location and was surprised that he never met the new Lantern Recruit. It was part of the ring selection process that the new recruit would be informed of the oath and be brought back to planet Oa for training and assignment.
This had not happened ever in the history of the Green Lantern Corp. There must be some special reason the ring failed to do as it was supposed to do.
A young woman named Laira Omoto speculated that maybe the ring felt that it should allow it's current Lantern finish any unfinished business on the planet before asking that he make the oath, it was something Abin Sur would have done.
Sinestro told his recruit that it was unheard of for a ring to show such consideration towards any Green Lantern. It basically would put thousands of worlds at risk for the benefit of a single Green Lantern and it would be something both foolish and selfish. Something the Rings of the Corp would never do.
It would take an extra four years where Harry demonstrated his quick learning and talent. He was considered by many of the young witches to be both quite the catch and quite the weirdo. He had onced drawn a picture, almost a small portrait in fact of a beautiful lady with red haired and wearing a beautiful dress, it would be easy to think it was Ginny Weasley but the fact that the young woman had purple skin made it obvious it was not.
He placed the picture by his dorm room beside. He would kiss the picture each night and say, "Till the sun illuminates your beauty, good night Laira, my love."
The last of the obstacles for Harry was during something they called the tri-wizard tournament and it was during those days that he used the power of his ring to great and amazing effect. No one knew it but Harry had studied everything he could learn in the four years he had spent living in the castle.
The fact was that after Albus attended the trial of Vernon and Petunia Dursleys it was clear he should have listened to Minerva when he was told to reconsider leaving young Harry with the monsters on trial. Dudley tried to punch a dementor and was kissed by the same as his appropriate punishment.
Petunia was sentenced to the maximum security wing for no less than 750 years and a kiss after she finished her long sentence. It seems fate did hear the wish of Harry Potter that day. Vernon much like his son tried to resist being taken to his cell and like his son he was kissed by the dementor he offended.
Harry had no recourse but to live as a ward of Hogwarts and lived on the castle as his home. After a long tournament he was at long last facing the murderer of his parents, he used his magic much to the death eaters present to kill and destroy the remaining horcruxes and the rather nasty familiar.
"Harry there was no need to do that you know, I merely wanted to test your skills. Now I will have to go and kill seven people all over again and find seven knew artifacts to make the next horcruxes. Thanks for nothing kid. "
Harry smiled at him." There is no way I will allow evil like you to continue. I will see justice be done and you pay for your crimes. " Voldemort did not like the sound of that." Wake up kid, you are no police officer or even an Auror. You have no chance to defeat someone as mighty and powerful like me. "
He immediately summoned his green armor, an armor he saw in his dreams and a green mask on his face. " I am a police officer but more than one simply for this world. By the light of the green light of will and by the authority of the Green Lantern Corp you shall be brought to justice."
"There is no such thing as Justice, Justice is the excuse and wet dream of the week. There is only power and those who don't have it or have the bravery to use it. But if it is a spanking you want who am I to deny you your death wish. "
The fight was over and with a shield made of green light he reflected the killing curse a second and final time. Voldemort was finally dead and the prophecy had come to pass. His time on this world was over. He went to Albus and Minerva and said his farewells. The two had felt like he was sort of a surrogate son and now they were watching their boy finally become a strong enough to deal with anything life sent his way.
With the battery in hand he stood in the large clearing in front of the castle and began to say something that many like him before him had said.
"In the brightest day and in the darkest night
No evil shall escape my sight
Let those who worship evil's might.
Beware my power, Green Lantern's Light. "
As he finished he flew away from the planet and no one knew where he would go, but they were sure of one thing Evil everywhere would one day fear his coming. Many of the former death eaters turned themselves in and their children turned a new path in life. Or else they would one day face Harry Potter or what the Green Lantern Corp came to call him the Green Lantern Mage.
