Harry was going through Dumbledore's office. He was desperately searching for the Dimen-Twist, a small object that allowed dimensions to be twisted together. He had seen Malfoy toying with something like that, but that wasn't possible, there was only two, and he had only invented two, one for himself and one for Dumbledore, and he had his in his pocket, that meant that either he was imagining things or Malfoy had somehow stolen Dumbledore's, and if a thing like that fell into the hands of a Death Eater like Malfoy, then all hell was going to be set loose.
Harry could not find it, and he panicked immediately, Malfoy had it, he thought. He had it and if he figures out how to use it he will bring every villain from every dimension to this one to become allies with Voldemort. He raced down the stairs as he thought this, adding more speed every footstep in hopes of getting to the courtyard to prevent the oncoming disaster. As he ran he bumped into Ron and Hermione, Harry quickly relayed the events and all three of them raced out to the courtyard, just as Malfoy showed off his prize.
"Malfoy, give that back!" yelled Harry.
"In your dreams, Potter!" cackled Malfoy.
"Look here pea brain, give it back, it belongs to Dumbledore!" yelled Hermione
"No! I feel like playing with this," Malfoy said as he twisted the top of the Dimen-Twist, causing the villains of all the other dimensions to come into one standpoint, and not necessarily on this plain of reality.
Harry noticed just in time and twisted his Dimen-Twist and managed to bring the Heroes as well, for the Dimen-Twist reflected one's heart, if it was good the heroes would be brought, if it was dark then the villains would be brought but Harry was going to make sure that didn't happen.
Harry woke up in a bright sunny field, with a couple of people that he recognized such as Ron, Hermione, Malfoy, and to his surprise his sister Kat was also there, though she was not unconscious, and was eating nerdelings, a candy that she her self had invented, which could give the eater powers, if they knew how to call upon them, and so far she was the only person that knew how.
"Kat, how did you get here?" Harry spied his sister quickly hiding an object that, curiously enough, looked like the Dimen-Twist. "How did you get one? I only invented two!"
"You only invented two. I invented my own with a few modifications of course." Kat responded with a hint of smugness.
"Fine then! I wonder who these people are." He said more to himself than to anybody else but his sister answered, quite promptly.
"That's Naruto Uzumaki, Sakura Haruno, Kakashi Hatake, and Jiraiya" she pointed at a boy with an orange suit, a girl with pink hair, a guy with a mask on his face, and a white haired guy, "They are ninja from Konohagakure, or as it is mostly known, the village Hidden In the Leaves."
As she said this the four mysterious characters got up, shaking their heads with terrible headaches. They looked around and noticed that they were not alone. The one named Kakashi immediately took on a fighting stance, while the one called Naruto, who was about as tall as Kakashi, launched himself at Harry apparently convinced that Harry had somehow snuck up behind them and ambushed all the people, but that was not a brilliant idea.
"Shadow Clone Jutsu" he yelled.
"Shadow Clone Jutsu" Kat ran and conjured the Jutsu in front of her brother as she prepared for another attack.
"Naruto, stop!" ordered Kakashi "It's just Kat!"
"Who?" asked Naruto.
"Kat, you know, that mysterious warrior that appeared out of nowhere and then knocked Jiraiya out because he was a peeping tom and a pervert." Sakura said laughing at the memory fondly.
"Oh, that girl. Yeah I like her." Naruto replied.
"Well, I don't." Jiraiya pouted.
"Well you wouldn't especially since you are still walking with a limp, and she destroyed all your Itcha Itcha books and research." Kakashi said slightly sad at the end.
"Errrrrr… rrrrrr… rrrr…rrr…rr…r," Ron droned out trying to get someone to pay attention to him, at least once, "Guys, do you realize that we are surrounded by other people and that some of them don't look so nice." He said pointing at a small blond boy with a metal arm and leg and a giant suit of armor.
"That's just Edward and Alphonse Elric, oh and they came with pony boy, I mean Mustang, and he brought his little troupe, Hawkeye, Havoc, Hughes, and guys" she addressed the group "Please don't get him started on his 3 year old, he will take out pictures, and show them to you at completely random times, like when you are in the restroom, bathing, in a battle, sleeping, eating, watching TV, and other more awkward situations. Trust me one time I asked for toilet paper, and he slipped a picture instead and started talking about how he potty trained her for 5 hours until I threatened to use a Permanent sticking charm with his lips." As she finished saying that the ones mentioned above awoke Edward first, Havoc last.
"Hey he is short, really short." said Ron and Naruto, pointing at Edward
"WHO ARE YOU CALLING A PERSON SO SMALL THAT HE IS CONFUSED WITH SANTA'S HELPER ELF?!" yelled Ed racing toward the pair of boys.
"Brother! They never said that!" exclaimed Al.
"But they are right." Mustang jaded Ed.
"Shut it, you wrinkled narcissist bastard with a god complex!" Ed retorted back.
"Uh, guys, I hate to interrupt the love fest but there are people watching us" Hughes said.
"Who are you?" asked Hawkeye her hand now on her revolver.
"Well, since I don't feel like explaining every single person that wakes up, I am just going to magic the explanations to everyone." Kat took her wand out and muttered some words and pointed her wand over the entire group, conscious or not.
"And so they will just wake up, here are the rest who are here. Ahem, Ichigo Kurosaki, Rukia Kuchiki, Uruyu Ishida, Orehime Inouye, Renji Abbarai, Yoruichi, and Kisuke Urahara, more commonly known as Mr. Hat And Clogs." Every one woke up and introduced themselves though it really wasn't necessary. Nothing really eventful happened, just people being called short, asses being groped, and a couple broken noses.
"Well if that is everyone…" Kat stopped and stared a youth with blue chicken butt hair. It was Sasuke. "Incarcerio!" Ropes shot out of her wand and tied Sasuke from neck down, she bent down and Chakra enforced the ropes. "Locomotor mortis!" Sasuke levitated into the air as she conducted him. "Now we can leave."
"To Hogwarts?" asked Harry.
"To Hogwarts." Kat confirmed.
"Everyone grab someone with a wand, and don't let go, don't think or you might just end up with out certain body parts, metal or not." Harry said as he thought of Hogwarts, especially the Room of Requirements, and he twisted in place into the nothingness that is Apparition.
