Here ya go. We own nothing.

Xander grimaced as he sat down to eat the next morning. There was about to be trouble for a lot of people. Namely the Marauders. And seeing as he was a new member he had rigged it; though it had been rather easy. The prank was simple; the Slytherins would eat a bit of food and all of a sudden they would be doing pole dances on all of the house tables. It was, in essence probably a good thing that he did not have Potions class today.

It might not help that today was the day that they were supposed to practice the Patronus Charm in front of the whole class. The giant wolf like creature that would appear would bring back to many memories for his liking. Memories of the days when he was with his friends and laughing about the latest joke product from the twins shop or curing the common room walls as they did some odd essay that would have put Dumbledore to sleep. But there was no escaping unless you somehow broke bones outside of the class.

Xander sighed softly as James produced the best of the class efforts; a thin mist of silver, nothing that would hold off a Dementor. But then it didn't have to hold off a real one, not yet at least. And then it was his turn and he stood up and walked to the front of the room and drew his wand. The wood felt cool in his hand and when the professor, he couldn't remember his name, not when the man was sentencing him to a run down Memory Lane, nodded he searched for a happy thought. It was the first one that came to mind and the changes it produced were amazing.

The wood of his wand became warm and soothing and his eyes became tinged with amber and green. It was the memory of being in the same room as Remus when the other had been touching his forehead with his gentle hands and the feeling that everything might be all right. Raising his wand he focused on the memory.

"EXPECTO PATRONUM!"

The giant figure of the wolf appeared, it eyes gleaming with power as it turned towards the class and let loose a thunderous snarl that made everyone scoot back and fear take over their features. Then the wolf turned to the teacher and bared fangs that out Moony to shame. It wasn't like a real Patronus, not all the way. Its body was a hazy gray and its eyes a gleaming amber. This was a creature of the night. This was the devil of the future Hogwarts, its guardian but a devil all the same. The Guardian Devil, a creature that protected the darkness from the darkness. This was his double persona and as it advanced on the teacher Xander called him back with a low whistle. The massive creature turned towards him, gave him a look and disappeared. Xander looked at the teacher and smirked.

"I told you that this would have repercussions. Devil doesn't like to be messed with, Lord Hell or not." Xander murmured as he retook his seat amongst cheers from both the Slytherin and Gryffindor houses. Producing a corporal Patronus like that was among the most advanced of Light magic. Even the Death Eater students had to applaud the abilities and power. The professor, startled and more than just a little scared of his student, assigned interhouse projects.

Xander inwardly moaned when he was placed with Severus Snape. The young man wasn't as bitter as his future self but then that didn't matter, he would never be that bitter if he, Xander, was going to put his plans into action. And not get caught, he didn't need to get caught. Messing with the future was a high offense. Life in Azkaban if he was correct in his thinking. But then, so was forcing someone to take a Mark that would bind them to that person, like the Dark Mark. The phoenix tattoo on his own arm bound him to no one; it merely warmed up when there was one of the inner circle present. And that was what was needed. Despite natural belief, however, he did not hate his future professor. They had both gained a healthily respect for the other in the future.

With a grim expression Xander sent the other a note asking to meet at the library tonight after dinner. Receiving a yes he set about plotting the project that hr had bypassed in the future because the final phase of the war had begun. In a mocking way Xander stared at the professor for a moment before turning his heightened senses to Remus, who had taken the seat next to him. The full moon would be rather interesting with a black wolf running around with the Marauders. But then, the fact that he was really going to jack with the future might help. As the class ended, his last for the day, he walked out humming the tune to "Almost" by Bowling for Soup. (My story, I play it out like I want)

As he walked he sensed someone come up beside him before he was spun around and pressed up against the wall. Xander found himself staring into the calculating eyes of one Lucius Malfoy. Xander's eyes flashed greenish-yellow before he reined in his fierce temper.

"You hurt him and you will die."

The warning was growled and Xander's fierce temper flared beyond control. With a quick shift of weight Lucius Malfoy was pinned against the wall. The young aristocrat found him self staring into serpentine-gold eyes and an animalistic snarl.

"And you hurt Remus and you will find yourself running from a werewolf." Xander said the words more of a growl than anything else. A slight nod was his answer and the two separated themselves from the others presence, Xander to analyze future events to figure out Malfoy's attitude and Lucius to study the young wolf from afar. It didn't take long for Lucius to come up with the few answers he needed.

As the time passed Xander worked on his project with Snape and gained even more respect for the future Potions Master. It was when the next full moon came along that he put the first phase into action. He decided to work late and see what would happen. Snape was all too agreeable to get the project over when Lucius appeared, ready to escort the intelligent Gryffindor to were he needed to be. Snape followed, watching as the young wolf walked with confidence. They were just inside of the Entrance Hall were James and Sirius were waiting and it was then that one of the pieces fell into place and the pale light of the full moon danced across his skin.

Xander fell to his knees and for once let the transformation take place. Pain coursed through his body and as a scream ripped itself from his throat it morphed into a deep howl. His hands curled into wicked claws even as his body began to shift. Fangs grew from his human teeth even as fur grew all over his body. Muscles ripped and pulled at bones as they tried to rebuild his body structure. Malfoy and Snape were both to afraid to move when a large black wolf turned glinting serpentine-gold eyes to them and stood. One shake of his great body and the creature crouched down, its pearly teeth gleaming in the light. With one giant leap the monster lunged for Snape.

Xander knew that now that the wolf had control he was stuck in the backseat. But even as he leaped at Snape he knew that this defiantly hadn't happened and grinned. What fun.

The wolf landed right on top of the startled Snape and was about to sink his teeth into the others shoulder when a black blur flew into him, knocking him away from his prey and pinning him to the ground. With a deep, murderous sound the wolf fought the dog and let loose another snarl when he managed to kick the dog away. Climbing to his feet with a look of royalty the wolf glared at the creatures in front of it, looking for a human. It found none, but it did find a stag, a dog, a pure black panther, and a white-blonde panther. The two great cats stood side by side cautious looks in their eyes. With a growl the wolf advanced stiff legged when the door burst open to reveal another wolf. This one was brown and not quite as big as the black one but still a great size.

A rat scurried along the wall and the four larger animals
