No More Mr Nice Guy: A Harry Potter Fanfiction

Disclaimer: I do not own Harry Potter or any of its associated characters: all rights belong to JK Rowling. I do not own any crossover references used in the story: all rights belong to their original creators. I do own any OC spells explained at the end of a chapter.

Plot: The Dementors did more than take Harry's chance for family. Thanks to them, something was awoken in our hero that changes everything for him and those who think they know who Harry Potter is and what he's capable of.

Author's Note: So, I imagine something like this has been done before, but this is my own take on the theme with a load of fun and interesting points and ideas throughout. I also hope people enjoy a dark take on some of the more-classic tropes with a few good surprises thrown in there for good measure.

Anyway, let the adventures begin and, as always, if you don't like it, don't read it.

Chapter 1: The Last Straw

"EXPECTO PATRONUM!"

It was his last chance, Harry knew that much, even as he commanded the spell, probably breaking some ancient law of time at the same time, but he couldn't care about that right now. Not when his last chance to have a real family who wanted him there, who wanted him to be the best he could be and then some, and who wanted to love him for him, magic and all, was within his grasp.

Ignoring Hermione's scream for him to stop, Harry poured every ounce of emotion into his spell as he stared across at his past/other-self, who could only watch as a bright, all-encompassing flash of white light flew from the present/time-travelling Harry's wand. Unlike what had happened on the other side of the lake, however, Harry's eyes widened when he saw the white light that flew from his wand take on a new shape; a bright, almost-corporeal shape that charged straight at the Dementors, sending them flying away from the past-Harry and leaving the soul-hungry monsters unable to finish the job they started on past-Harry and the unconscious Sirius Black.

However, while the past-Harry then collapsed, just as present-Harry remembered he had done, the present-Harry frowned, even as his Patronus began to fade away, as he noticed something that was off with the other side of the lake.

His past self was now unconscious, of course, but there was something really wrong with the scene…

Or rather, there was something wrong with Sirius!

"Harry, do you know what…"

Before Hermione had a chance to scold Harry for his actions, however, Harry left her standing in the shadows of the Forbidden Forest as he ran around the lake, putting more speed, energy and determination into his movements than he'd ever done before. His heart ached with the strain while his energy levels were more like dregs running on adrenaline, like when you whack batteries to get another few minutes out of them, as he ran around the lake.

Stopping before he reached himself and Sirius, Harry gulped once before, checking to see if anyone else was coming, he waited for only a moment to be sure before he ran to his godfather and his past self.

Once there, he kneeled down and, using the tip of his wand, he poked Sirius' cheek, but, to his alarm, there was no response from Sirius; he was pale, glassy-eyed and seemed to be unable to look anywhere, but straight ahead. His chest movements were barely even recognisable, but, when Harry dared to put his hand over Sirius' mouth, he felt a very faint, almost-indiscernible wisp of air, but, other than that, there was nothing that might suggest Sirius was even aware of his future/time-travelling godson standing over him.

In laymen's terms, he was a vegetable.

"No…"

"Harry!"

Harry barely felt Hermione grab him and yank him away from the lake, as well as the fact that two Harrys were standing in one place at the same time, while he gasped out, "No…"

"Harry, how many times? We can't be seen!"

"No!"

"Harry, we have to go!"

"NOOOOOOOO!"

No More Mr Nice Guy

In another part of the forest, the Ron and Hermione from the past, as well as a conveniently-conscious Severus Snape and even the roaming, hunting werewolf Remus Lupin all heard a loud, wailing scream that sounded like grief, darkness and death itself rolled into one.

And when they heard the sound echoing through the night, like the wailing cries of the damned, each and every one of them, even Snape, trembled in fear, pain and dread as a sense of ominous darkness washed over them.

Although, by the end of the night, only one of them would feel anything for what they'd heard that might be called positive and supportive.

"Harry, what were you thinking? I told you we couldn't be seen! I told you to stay hidden! I told you…"

"YOU LIED TO ME!" Roared Harry, his voice filled with hurt, hatred and no small amount of grievous pain as he spun around to face Hermione, who didn't look like a friend who might want to console another friend. In fact, to Harry's ire, the only thing she seemed to care about was the fact that Harry had risked breaking the laws of time itself to confirm a dark, terrifying truth that even the brunette didn't see.

"What?" asked Hermione, shaking her head as she asked, "What are you talking about? I never lied to you…"

"You said we could save him!" snapped Harry, rage building up in his voice while his green eyes seemed to have taken on a new glow that made them look like the curse that had made him famous – not that Harry knew that yet – as he glared at Hermione, "You and Dumbledore…"

"Professor…"

"I will call him what I damn well want to call him, Granger!" snarled Harry, his hands clenched so tightly that his fingernails were cutting into his palms as he snapped, "The fact remains you and him said we were doing this to save Sirius…you do remember Sirius, don't you? My godfather, a man who spent twelve years in Azkaban for a crime he didn't commit and the guy who was basically my Father in a new body!"

"There were rules!"

"SCREW THE RULES, I'M HARRY-FUCKING-POTTER!" Snarled Harry, his roar coming with a rumble of thunder as he asked hotly, "Or did you just forget that both Snivellus and everyone who thinks they can just bitch about me loves saying how the rules don't apply to me? After all, where others die, I didn't, where others would have given up and been destroyed, I rose again like a phoenix from the ashes, where others had nightmares and the demons of their past break them, mine made me stronger! So, no, Granger; the rules definitely don't apply to me…"

While Hermione looked somewhere between alarmed and disbelieving, Harry's eyes glinted just like the old bastard whose name he was taking in vain as he added, "And, do you know? Now I think about it, they don't really apply to you either."

"What…what do…what do you mean?"

"I mean, you just happened to have spent the past year jumping through time with a magical device capable of letting you do that…"

"Yes, for my lessons…"

"Bullshit!" spat Harry, advancing on Hermione as he smiled cruelly before he went on, "Do you know? I think someone wanted you to have this, not for lessons, but for an act of coincidence that they could use when it suited them. Of course, this is all just theory: I mean, I saw me on the other side of the lake, which then led to you being given the idea, which meant I was there for me to see myself saving myself and…"

"Harry, that doesn't even make sense."

"It's magic, Granger, what does?" asked Harry, stepping back from Hermione as he added, "Well, it doesn't matter anymore, because I'm done playing by the rules…any of the rules. I'm going to find out who is so intent on screwing me over and then, when I find them, I'm going to make them sorry they ever heard my name."

"Harry, this isn't you…you're…you're under an enchantment…you're confused…you're…"

"Haven't you forgotten something?" asked Harry coolly, earning a shocked look from Hermione as Harry smiled before he lifted a familiar gold chain out of his pocket, earning a horrified look from the brunette as her hand flew to her throat, where the Time Turner was, indeed, missing.

"How did…"

"I'm a Marauder's son and godson," said Harry, his green eyes now more like the Killing Curse ignited as he told Hermione, "And it's time I get back to what I've always had to do and been the best in the world at doing…looking out for number one."

"Harry, you can't…"

Before Hermione could finish, Harry released a finger from the Time Turner, sending it spinning violently before, to Hermione's alarm, the furious-eyed young man vanished in a whirlwind of golden sparkles, though not before his voice echoed through the darkness one last time.

"No-one will tell me what I can and can't do ever again, Granger…after all, I'm all I've got left now!"

Then, he was gone.

No More Mr Nice Guy

When Hermione tried getting Buckbeak to help her back to Hogwarts, the Hippogriff left her scratched and running through the woods herself, her mind filled with fear, terror and disbelief as she raced back to school before she found herself in even greater trouble with Professor Dumbledore.

She just hoped he was still there when she arrived, so she could tell him what Harry had gone and done.

Yes, if anyone could talk any sense into Harry for being so stupid and not listening to her advice, it was Professor Dumbledore.

After all, he was Dumbledore.

Who wouldn't listen to him?

Yikes, talk about a weird start and a crazy change that seems to have taken hold of our hero: however, now lost to time, what will he do about his decision to no longer listen to anyone's voice, but his own?

Also, I know you're all wondering it, so I'll ask it too: if he's jumped through time, could he be planning to save Sirius? Or has grief, darkness and thoughts of justice at any cost clouded yet another innocent mind into madness?
