AN: here's chapter ten for you all; I bet this chapter will surprise most if not all of my readers, it even surprised me with the way it went. Oh and just to be clear Blaise Zabini is a GIRL in my fic as the character was established as female in fanfiction long before J.K and the HBP movie showed the character to be a boy; so in my fic Blaise Zabini is female…

The battle for Hogwarts

Hogwarts great hall, fives hours later

"Welcome home hero." Neville said to Harry with a grin as they entered the entrance hall and began heading towards the great hall with the rest of the students.

Harry had hardly stepped foot into the great hall when he heard his name being spat at him.

"Potter!" A voice spat the name in clear anger, turning, every one in the great hall and Harry saw the Headmaster Albus Dumbledore advancing towards him with anger on his face and his wand drawn as though he was walking into a duel and by the looks of things he very well just might be as Harry withdrew his blackthorn wand and readied himself for a fight.

"Headmaster, how can I help you?" Harry asked Dumbledore politely yet with an air of cautiousness in his voice. Harry knew at that moment in time it would most probably be unwise for him to fight the Headmaster but he could not help but feel that maybe it was time for him to get some well dissevered payback on the man.

"First you can tell me just what you are doing here." Dumbledore replied with none of the eye twinkle or warmth in his voice as he used to have when speaking with Harry Potter.

"I have come for my 7th and final year sir, after-all I need my N.E.W.T.S to get a job after the war, assuming I survive the war that is." Harry replied in that same polite yet cautious tone; he was thankful that Dumbledore had not come over curses blazing and had his wand pointed down, yet ready to use.

"Then why did you not return last year for your 6th year of learning?" Dumbledore asked in that same tone; he was vaguely aware of the students taking their seats whilst listening to the conversation between himself and Harry.

"Because I'm destined to defeat or be defeated by Lord Voldemort and I needed to train so as to give myself at least a fighting chance." Harry replied in an even tone; out of the corner of his eye he could see that Neville had his wand at the ready just incase a fight broke out and he was very grateful to his friend for his silent support.

"Well I'm afraid it does not matter why you did not return for your 6th year." Dumbledore began with a strange smile coming to his face. "I simply cannot allow a murderer to be a student at Hogwarts, so I'm afraid I must ask you to remove yourself from this castle and grounds." Dumbledore smiled victoriously as he finished his explanation.

"I am not a murderer Dumbledore." Harry replied in a fierce voice even as the students gasped at the headmaster calling him a murderer.

"Not a murderer, what do you call killing all those men and women at the Greengrass family home then?" Dumbledore asked in a way that he had just played his trump card.

"I call that pest control and saving a family from certain torture and death." Harry replied in a hard tone, he could see the Greengrass sisters nodding their agreement of his words.

"You murdered eighteen people who you could have been captured and allowed them to stand trail and face the consequences of their actions and maybe redeem them selves." Dumbledore argued back in an equally hard voice.

"Redeem them selves; there is no redemption for Death Eaters." Harry began passionately, he continued quickly before the Headmaster could interrupt him. "Do you know what they have to do to earn their Dark-Marks? They have to kill two innocents, rape three virgins and then finally torture four men and women; after all that and any others they have killed leaves them no room for redemption." Most of the students gasped at the acts needed to be committed to become a Death Eater, more than one turned a little green in the face while others went white at the thought.

"Nevertheless, you could have given them the chance to redeem and see the light." Dumbledore replied with a hard edge to his voice even as the students and most professors looked at him in disbelief that he could think people like that deserved a second chance.

"You mean like Snape did after he told Voldemort the first part of the prophecy?" Up at the head table Snape gasped and went paler than normal at Harry's words. "Or like you're hoping you're former lover Gellert Grindlewald will see the light as you keep him locked up in Nurmengard?" Harry smirked as the students gasped at his words once more; nobody called him a murderer and got away with it.

"Don't talk about things you don't understand." Dumbledore growled in warning as he glared at Harry.

"Oh I understand better than you think old man." Harry hissed coldly with a smirk on his face. "Tell me, did you ever find out whose curse killed poor Ariana?" He knew that that was a low blow but he could not resist asking and he was curious to know if they had ever found out whose curse killed the poor girl. The students once more gasped at his words as they processed just what he had said.

"YOU GO TO FAR." Dumbledore yelled as he brought his wand up to curse Harry. "Sopio." The students and professors were shocked when the Headmaster fired a curse at Harry but they were even more shocked when Harry just swatted the curse aside as though it were a fly, the curse flew across the hall were it smashed harmlessly into the wall.

"So it has come to this." Harry began in quiet, calm voice as he looked around the hall then back at Dumbledore. "Who will stand behind you as you battle me and my army?"

"The teachers of Hogwarts and the Order of the Phoenix will stand behind me as I extinguish your darkness." Dumbledore spat with confidence as he readied himself for the coming battle.

"Very well, Potter's Legion to me." Harry called loudly causing all fifty three members of the Legion to rise from their seats in the great hall, before they all crossed the great hall to stand behind and beside Harry, taking out their wands as they did so. Too Harry's right was Neville Longbottom and too his left was surprisingly Tracy Davis.

Up at the head table, tiny Professor Flitwick was shepherding the younger students and those not willing to fight on either side into the antechamber off the side of the hall and too safety.

"Are you sure you want to do this old man?" Harry asked tauntingly as he and Dumbledore waited for the younger students to exit the great hall; neither of them were willing to start the fight and possibly injure an innocent child.

"I have no alternative; your darkness is as dark as Tom's is, if not darker." Dumbledore replied in firm voice showing that he truly believed that what he thought was true; that Harry was aiming to become the new Dark Lord.

"Very well old man, call your fighters." Harry noticed that all the teachers except Flitwick and Fleur Delacour where standing with the headmaster with their wands at the ready, even Hagrid.

"Very well." Replied Dumbledore as he reached a hand down the front of his robes to retrieve his Phoenix pendent; However unlike Harry and the Legion, he did not realize that Flitwick and Fleur had moved the rest of the students to safety and Harry saw that as his opening.

"Acer." Harry silently and quickly fired the piercing hex at the Headmaster catching Dumbledore off guard and kicking off the battle for Hogwarts. The piercing hex smashed into Dumbledore's wand shoulder and punchered a hole right through the shoulder causing Dumbledore to grunt in pain.

"Confringo." Dumbledore's silent blasting curse was blocked by Harry however the power behind it backed the teen up a few steps as the battle between the teachers and the Legion raged around the two warriors.

"Sectumsempra" This time it was Dumbledore's turn to swat aside Harry's curse as he blocked the dark cutting curse before he returned fire with another advanced stunning spell that Harry leaned to one side to avoid.

As Harry and Dumbledore began trading curses and hexes faster and faster, Neville Longbottom, Tracy Davis, Colin Creevey and Lisa Turpin were battling against Severus Snape in a four-on-one duel that the Death Eater turned spy was hard pressed to defend against even with his skills in dueling.

"Reducto." Neville hit Snape in the collar bone with the basting hex breaking the bone on contact and causing Snape to roar in pain.

"Cerebrum Frangat." Tracy then followed it up with a shattering curse to Snape's wand hand shattering both Snape's hand and wand causing him to roar in pain for a second time as he was slowly been picked apart.

"Sopio." Colin then hit Snape full in the face with an over-powered advanced stunning spell dropping the spy to the floor with a satisfying thud.

"Incarcerous." Lisa conjured steal chains to wrap around the Potions master to make sure that if he did come back around while the battle was raging that he would not be a problem anymore.

On the other side of the great hall Pomona Sprout was very hard pressed to defend herself against Blaise Zabini, Dean Thomas, Ernie Macmillan and Hannah Abbott after-all she was a teacher at heart not a battle hardened warrior. Not to mention she was reluctant to fight her students even if they were rebelling due to the fact that they believed in Harry Potter a hell of a lot more than they believed in Albus Dumbledore. Just before she was hit by four simultaneous stunning spells, Pomona cursed Dumbledore for antagonizing Harry Potter instead of leaving him-be as he fought the war against Voldemort.

Minerva McGonagall considered herself very skilled in the magical arts whether that be Transfiguration, Charms, Potions, DADA or dueling, however with all her skills she could not win a duel against five opponents as she too was reluctant to battle against her students who were not evil or Death Eaters but believed in their leader Harry Potter and she too dropped to four simultaneous stunning spells just like her college moments before.

Rubeus Hagrid did not even try to fight the students even as he was surrounded by fifteen members of the legion. He had only stayed behind to see who would win the battle between Dumbledore and Harry that was still on-going. He was sad about the fact that he had lost all faith in Albus Dumbledore who was convinced that Harry was a rising Dark Lord when it was clear that all Harry wanted to do was make the Wizarding world a safe and happy place once more. Hagrid wanted to see if Harry could defeat Dumbledore in a fight because if he could then Harry Potter was the right person to be the leader of the light and the one everybody should throw their full support behind in the war against Voldemort.

"Stupefy." Dennis Creevey dropped the Hogwarts librarian with a stunning spell. The reason the Legion was using mainly stunning spells was simple really as they had been instructed to use the lethal spells against Death Eaters and/or Dark Witches and wizards. And the professors of Hogwarts were certainly not dark witches or wizards just human beings blinded by their faith in a washed up old has-been, Albus Dumbledore.

"Avis." "Oppugno." Hermione Granger yelled conjuring a flock of canaries before she set them too attacking her opponent.

"Incendio." Daphne Greengrass silently incinerated the flock of birds with the fire spell before she shot another spell at the Muggle-born bookworm. "Coniuro Leo." However the spell missed its target or so Hermione thought until she heard a loud roar behind her that distracted her and turning quickly the bookworm saw a huge man-eating lion heading her way giving Daphne the advantage she had been looking for.

"Sopio." Daphne took advantage and dropped the Muggle-born with an advanced stunner to the back before she turned to watch the on-going battle between Harry Potter and Albus Dumbledore. After she had vanished the transfigured lion of course.

"I yield." Madam Pomfrey cried as she threw her wand at her opponents feet; she was a healer not a fighter after-all and she had no desire to fight for a headmaster she no longer had any faith in.

"Stupefy." Astoria Greengrass hit the Hogwarts healer with the stunning spell before she too turned to face the on-going duel between Harry and Dumbledore. All the professors had either been overcome due to the odds against them or had yielded the fight and had been stunned. Only Hagrid and Dumbledore remained standing and Hagrid had fifteen wands pointed at his face ready to take him out should it be necessary.

"Avada Kedavra." Dumbledore shocked the entire legion and Hagrid when he fired the killing curse at Harry who quickly levitated a plate into its path successfully blocking the jet of green death.

"Excaecatio." Harry's blinding hex was only just blocked by Dumbledore who due to the cheep shot by Harry at the start of the duel was unable to fully use his wand arm giving Harry a huge advantage. Both fighters were bloodied and battered (Harry more so than Dumbledore) and both were down too their last curses as they were exhausted physically and magically.

They both knew that the next curses thrown would win the duel one way or another; Dumbledore arrogantly believed that there was no way he could lose, Harry however had an ace up his sleeve that just might guarantee him the win.

Harry heard Dumbledore shriek as he, too, yelled his last curse to the heavens pointing the blackthorn wand.

"Confringo Maximus." Dumbledore shrieked at the same time that Harry yelled his last curse.

"Cerebrum Frangat." The two powerful spells met in the middle and connected in a ball of magic turning the final moments of the duel into a power struggle; meaning that whoever had the most power to overcome his opponent would win; however Harry slipped his free hand into his robe pocket as he went for his ace.

BANG! BANG! BANG! Harry shot Dumbledore three times in the chest with his Cobra M2 dropping the headmaster to the floor on his back as the two spells frizzled out.

Harry limped his way over to the fallen Headmaster and ripped the wand from Dumbledore's hand causing the wand to flash briefly as it gave Harry its allegiance even if Dumbledore was just barely still alive. Harry looked down at the fallen Dumbledore who was breathing in gasps as he lay in a growing puddle of blood staring up at Harry who had now taken aim at his head.

"Hogwarts is mine old man." Harry hissed in a cold voice before his Cobra M2 rang throughout the great hall once more as Harry shot Dumbledore between the eyes killing the old Headmaster instantly.

One shivering second of silence, the shock of the moment suspended: and then the tumult broke around Harry as the screams and the cheers and the roars of the Legion members rent the air as they all thundered towards him; first to reach him was Neville who eloped him in a brotherly hug both he was engulfed by the Greengrass sisters then the Creevey brothers and then the rest of the Legion, everyone was ecstatic that they had indeed backed the correct person to lead them in the war against Voldemort.

"Well done Harry, you truly are the one to lead us against You-Know-Who." Hagrid said with a smile on his face as the cheering died down and Flitwick reentered the great hall. Hagrid was of course sad that Dumbledore was dead but the ex-headmaster had made the biggest mistake in his life when he doubted Harry and chose to fight him and it had cost Dumbledore his life.

"So what's next boss?" Neville asked Harry in a serious voice yet with a grin on his face.

"Next we bring Hogwarts back to her former glory and we start by removing all the students who are marked with the Dark Mark." Harry replied causing Hagrid and the Legion to cheer once more.

"And after that?" Daphne Greengrass asked as the cheering once more died down.

"We start training as hard as we can because soon, very soon we are going to start picking off Voldemort's Death Eaters one at a time until only Voldemort remains." The Legion and Hagrid cheered once more.

"But first we shall see if the Professor's are willing to work under a new Hogwarts leadership." Harry began before he turned to Neville. "I want you to take half the Legion and check every student in the antechamber for the Dark Mark, Imperius Curse and Polyjuice potion anyone found to have any of the three are to be stunned and bound until they can be dealt with properly."

"No problem Harry I'll get right on it, starting with Malfoy." Neville replied with seriousness written all over his face and in his voice.

"And that includes the first years waiting to be sorted, it's unlikely that there will be anything wrong with them but you can never be too sure where Voldemort is concerned." Harry explained before Neville turned and called half the Legion to him before he led them into the antechamber.

"I've revived Madam Pomfrey and she is willing to continue working in the Hospital wing with you as the new Hogwarts leader." Astoria Greengrass informed Harry pointing out Madam Pomfrey who was at that moment treating the minor wounds of the Legion members.

"Thank you Astoria, are you in need of medical treatment?" when the girl shook her head no Harry continued. "Then can you see to the first years when Neville has finished checking them, take them down to the kitchens and have the elves feed and water them and generally reassure them."

"Of course Harry, I'll get right on it." Astoria answered him with a nod and a smile before she set off towards the antechamber to begin her task.

"Susan can you arrange a meeting with your auntie for me?" Harry asked the redhead Hufflepuff as she passed him.

"Of course Harry I'll send her a letter right away, when would you want to meet with her? Susan asked as she took out a Muggle pen to write the time and/or date on her hand so she did not forget.

"Either tomorrow or as soon as she is free." Harry replied before he then gave out various other tasks to Legion members such as asking Colin Creevey to call Kingsley Shacklebolt and the Aurors to come and collect the marked Death Eaters minus Snape and Seamus Finnigan to arrange a press conference for the next day so he could explain the battle for Hogwarts and exactly why it happened at all as he believed that the public deserved to know the truth.

"Wingardium Leviosa." Harry levitated the bound and stunned body of Severus Snape before he left the great hall and headed towards the Owlery passing Astoria Greengrass who was escorting the first years towards the kitchens.

Upon reaching the Owlery, Harry cancelled the levitation charm allowing Snape to drop to the floor unceremoniously with a dull thud before he pointed his wand at the man and woke him up.

"Avada Kedavra." Harry hit Snape with the killing curse as soon as the man's eyes were fully open as he wanted Snape's eyes open to send his message better. He then took out a scarp of parchment from his robes and conjured himself a self-inking quill.

Tommy Marvolo Riddle,

Dumbledore is dead by my hand.

Hogwarts is now mine.

I'm coming for you and your Death Eaters

You have been warned.

Lord Harry James Potter.

Harry then conjured himself a sword that he raised above his head before he brought it down hard and fast across Snape's neck, severing the head from the body; with that done he conjured a cardboard box that he then levitated the severed head into before he sealed the box and attached the short message on top. Harry called for Dobby and had the little man pop the rest of Snape's body into the heart of Aragog's lair deep within the forbidden forest. Once Dobby had removed Snape's body Harry then hit the box containing his head with multiple feather-light charms before attaching the box to the legs of four owls and sending them to deliver the parcel to Tom Riddle aka Lord Voldemort.

With his message to Lord Voldemort sent, Harry limped out of the Owlery with Hedwig on his shoulder and made his way slowly towards the Hospital wing so he could get his own injuries seen to before he interviewed the Professors to see if they were willing to continue working at Hogwarts with him as the new leader.

End of chapter

AN: I told you that you would be surprised with this chapter. Oh and I did warn you all in the very first chapter that Harry would be very Dark in this fic and now we are seeing it but he aint evil. Now before anyone complains that students defeated teachers more skilled and at most times more powerful than them, the Legion members ganged up on them in four against one duels most of the time and they had trained very hard for almost a year in dueling while the teachers only taught their subject without training. And that is how Harry was able to keep up with Dumbledore and yet Harry was battered more than the Headmaster and he only beat him because he had his cobra M2 on him and got in a very good cheep shot at the start of the duel slowing down the Headmaster.

Flitwick or McGonagall to be the new/next Hogwarts Headmaster/Headmistress, please vote on who you think it should be and why because I haven't a clue which one to go with only that Harry will be too busy fighting the war and wooing the girls to trouble/bother himself with the everyday tasks of a Headmaster.

Please review!
