And that's it. The final chapter. Please let me know what you think.

The Exterminator.

I'd thought after I dealt with Voldemort and his bunch of thugs, I would never have to continue with this life, but here I am doing the work of the police who are either corrupt or they just turn a blind eye, Harry thought to himself as he followed from a distance a man wearing a large, formless coat. In the weeks since he had left the magical world, Harry had been wandering around while he had looked for something meaningful to do.

With Voldemort gone and after his clone had broken down in a pile of ashes in the Ministry of Magic in front of the Minister himself and confounding Dumbledore for the last time, Harry had taken the time to simply enjoy life, the life he should have had if Voldemort and Dumbledore hadn't meddled in his affairs or his parents were murdered following Pettigrew's betrayal.

He had travelled the country and he had plans to travel the world, hoping to live his life to the full. He had time after all; he had his education done and dusted in both the magical and the muggle worlds, and he had qualifications and masteries in both worlds, so theoretically he could do whatever he wanted in either world, or he could do anything in both worlds.

Harry had been following the events in the magical world. Understandably news of what he had done to Voldemort was front-page news, although some of the sensationalist journalists who were either mental clones of Rita Skeeter or just wanted to make a name for themselves. And of course, the British Wizarding world had swallowed it. Hook, line, and sinker.

Harry had already received in the goblin post box he had set up through Gringtots to screen his mail a number of booby-trapped letters filled with bubotuber pus which the box managed to banish, although he had made a note of where the letters had come from, and he had sent back a few cursed letters back to them.

He wasn't Hermione Granger, who had done little against the people who had sent her such things when Skeeter had stirred the shit back when the Tri-wizard tournament was going on and was constantly writing disgusting articles about relationships which were just as imaginary as Dumbledore thinking he was a god. He had no intention of letting anyone get away with sending him something so toxic, especially since bubotuber pus was so dangerous. Harry had made sure the curses did not harm children, but the people who had sent the letters.

But so many people had sent cursed or booby-trapped letters to him. Many of them were calling him a coward who had left them all to suffer and to die, so he had needed to work for a month when he could have been doing anything he had wanted. In the end, he had written a scathing holographic message of himself to be played in the Ministry, Hogwarts, Hogsmeade, and Diagon Alley. Harry smiled as he remembered it going off in Diagon Alley.

Harry's hologram appeared in Diagon Alley. The sudden appearance took the shoppers and commuters by surprise, but the hologram quickly began to speak before anyone could say anything negative about his actions.

"I have made this recording to let you know why I made the decision to not help the magical world, but instead to abandon it. Well, to each to their own. Why should I help a society which simply refuses to help themselves? You all carry wands, and yet you cower away and refuse to help yourselves when trouble comes out; what did you expect, that I was just going to allow you to push me like that forever? I had no idea how to fight, which is one of the reasons why I left. Since I left when everyone was deriding me, calling me an attention-seeking liar because I was making up tales Voldemort was back - oh its a name, you morons, get over it - why would I stand back and take it? I mean, come on - why should I?

"In fact, why would you think I would lie about something like that? Voldemort murdered my parents, and contrary to what you braindead idiots might like to think, I didn't grow up with a silver spoon in my mouth. I was forced to live with a family of stinking muggles who loved reminding me I was unwelcome, calling me a freak because I had magic. So while you lot were enjoying life, celebrating the death of my parents, I was in a cupboard under the stairs, alone, cold, and barely alive.

"I am sorry for the loss of life, but there is nothing I can do about it. I can't bring back the dead and yet you think if you send cursed mail to me it will help. Get a clue - it won't. The best thing you can do is to learn from the experience. Stop letting Dark Lord rise to power. Stop letting the bastards scaring you. Stand up for yourselves.

"Two days ago I nearly got injured because someone sent a letter filled with bubotuber pus. Let's just say when I sent them something back it should make them think twice about sending such letters again.

"Voldemort is dead. The magic he had used to keep him going failed, and now he and his followers have paid the price. The so-called light has won. Voldemort will never come back, and neither will I. Congratulations - I was wondering if I should rejoin the magical world, but thanks to you I won't. I also have a note for my successor, the next poor kid you lot elevate on a pedestal; beware the magical world, it is like a tide. One minute you are a hero, the next, a dark lord. Goodbye."

Harry pulled himself out of those thoughts, and he continued following the muggles. They were a bunch of teenage thugs who were part of a gang of thugs who had begun terrorising a large portion of Brixton. Ordinarily, he wouldn't have reacted, but he had decided to start off small.

Harry had made his choice.

He was going to be a vigilante in the muggle world. He would use a mixture of magic and muggle means, although most of it would be muggle since he knew the magical world would be looking for him, especially since he had sent out that hologram. Many people in the magical world simply could not understand how anyone could live in the muggle world, but Harry could, and Dumbledore knew that although Harry felt the old wizard would make the usual mistakes everyone else did when it came down to it. Dumbledore would consider what he would do in Harry's place, not the other way around, and since Dumbledore didn't know his way around the muggle world like muggle-borns like Hermione Granger or Justin Finch-Fletchley did, he would flounder.

Still, becoming a vigilante hadn't been something he had considered. Personally, Harry didn't see any real reason why he should care about some things since some of it wasn't his problem, yet at the same time, he realised he knew no other life.

He had been hanging around Brixton for some time now, and he didn't really have any trouble finding the gang members. He had asked around for ideas of who the gang were, wiping memories here and there so then no-one would connect the dots when he had wiped out the gang forever, although many people were either too scared or didn't care. Still, that meant nothing to someone who was a master of the mind arts.

It hadn't taken him long to find confirmed members of the gang.

Now he had their trail, he would wipe them out.

He was just the Exterminator.

Harry followed the gang members to a hangout.

"Who are you?" one of the gang members demanded when he took off the charm he'd placed on himself.

Harry smirked as he took in the scene.

By the morning the police came and were baffled by how each member of the gang had been killed. In the newspaper, Harry just cut out the story, and in the weeks that followed as he continued his self-imposed mission to impose justice on the world, Harry collected articles of the things he had done. At the same time, he looked out for child abuse. More than once, he found children being abused by parents and guardians, and he made sure they either confessed their sins to the police, or he killed them. Harry had no idea if he would ever settle down, but hopefully, if he stopped the same type of suffering he had endured, the world would be a better place. He also went out to other countries and tracked down one criminal organisation after another.

And he exterminated them.
