Okay so what would happen if you could trap any character you want from any Universe into a room for a week? Well... This is my version. :)

I OWN NOTHING! I just had this strange idea after reading some other crossovers. Hence my version. Also, Its the Room of Requirement, so its large enough and food some how randomly appears(even if its not really supposed to) so thats not an issue.

Chapter 2

Tony sat up rubbing his head, which felt like he was just struck by Thor's Hammer... Again. And that wasn't a pleasant memory. Anyway he sat up and looked around the room to see that there were a lot more people than just the Avengers... and they all seemed to be waking up as well. He watched, still rubbing his own head as people helped, who he supposed was their companions as Steve helped Natasha and Clint helped Thor up. While Bruce sat looking just as puzzled at Tony was.

Once everyone was up and standing they all looked at each other. James saw Severus and lounged, holding out his wand, along with Sirius. "What the Bloody hell, Snevillus!?"

Severus had his own wand out as well. "Wait, Harry, is that your parents?" Hermione pointed to James, who was threatening Severus and Lily who was trying to stop the man killing the former Death-Eater. James froze when he heard her say that and looked straight at her.

"Wait, what?" James said, clearly confused.

"I suspect she is talking about your son." Sherlock, of course had to interfere.

"I think maybe we should all introduce ourselves." Lily, being a voice of reason spoke up. "No interrupting." She shot a look at James and Sirius, who pouted at her, "And you say one thing about you. I'm Lily Potter nee Evans, and I'm a Muggle-Born witch."

"James Potter, The Leader of the Marauders." James smirked as Sirius snorted in response to that.

"Yeah he wishes. Sirius Orion Black, first Black to ever not be in Slytherin... according to my knowledge that is." Sirius grinned.

"And you turned out just fine, Paddy." Remus grinned at his friend, "Remus John Lupin. I'm the Marauder's brains."

"Severus Snape, Former Death-Eater and current Order member." Severus glared at James and Sirius who shot skeptical looks at him.

"Harry James Potter, The-Boy-Who-Lived." Harry looked at James and Lily, who stared at him.

"Ron Weasley. Harry's best friend...besides Hermione." Ron replied with a grin from Harry.

"Hermione Granger, brightest witch of my age." Hermione beamed proudly.

"Fred-"

"-And George"

"Weasley." The twins ended together.

"Weasley-"

"Wizard-"

"Wheeze's-"

"Creators." They switched back and forth, making sure no one could tell who was who.

"Why do you two even talk like that?" Hermione groaned.

"Talk like what?" Fred and George smirked as they both answered her together. Hermione sent the mock glares and they chuckled at her.

"Tony Stark, Iron Man, Billionaire, Playboy, Genius, and Philanthropist." Tony went right back to his snarky self.

"Steve Rodgers, Captain America, the World's first Super Hero."

"Thor, Son of Odin, God of Thunder!" Thor bellowed proudly.

"Think he'd be a Gryffindor?" Sirius whispered to James, who snickered causing Lily to hit the both of them and send them a glare when they pouted at her.

"Bruce Banner, I have... anger management issues." Bruce looked at the ground shyly.

"Natasha Romanoff, aka The Black Widow, I'm a master Assassin, been since I was a kid." Natasha clearly wanted to make a point that she was not going to tolerate anyone hitting on her.

"Clint Barton, aka Hawkeye, master Marksman."

"Katniss Everdeen, a Champion of the 74th Hunger Games." Katniss, held her head high, and Lily noticed she stuck close to two boys.

"Gale Hawethorne, I'm from District Twelve, and this one's only true friend." He smiled at the girl, who sent him a deadly glare.

"Peeta Mellark, the other Champion of the 74th Hunger Games." Peeta was the one with Blonde Hair.

"Ten Galleons he's related to a Malfoy!" Sirius called out. WHACK! "OW! What the bloody 'ell was that for!?"

"You don't make bets on people's heritage, Black." Lily growled, and Sirius mumbled something inaudible to anyone else in the room.

"I'm Nick Burkhardt, I'm a Grimm and Police Detective."

"I'm James Monroe, please call me Monroe, I like to play the Cello and work on Clocks."

"I'm Rosalee, I own a spice and tea shop." She smiled softly at everyone else.

"I'm Edward Cullen-"

"Bloody 'ell. Harry, you seeing who I'm seeing?" Ron blurted out before Edward could finish. Harry's eyes strayed from the other people in the room and he clearly stiffened when he saw Edward.

"Isn't that Cedric?" Fred blurted out.

"Looks 'lot like him." George nodded.

"I don't know what your talking about. I'm Edward Cullen and I'm a Vampire." Edward replied.

"I'm Jacob Black, I'm a werewolf." Jacob scowled when he heard James say, "Another Cousin of yours, Paddy?"

Sirius only shrugged in response. Remus paled considerably.

"Bella Swan, I'm in love with a Vampire." The girl standing between the two boys spoke. She received many questionably looks on that, but no one commented, to her relief.

"I am Sherlock Holmes, consultant detective." Sherlock was bouncing on the tip of his toes, as he spoke rapidly. His red and black checkered scarf around his neck, his hair in a wild state and his eyes watching everyone all at once.

"Well, I'm Dr. Joan Watson, I'm Sherlock's Assistant." The Asian standing next to Sherlock spoke calmly, and he shot her a look, but she thanked god that he didn't say anything.

"Ben Gates, I found treasure from the Founding Fathers hid and had the Gates family receive credit for the discovery." Ben, stood next to Abigail with Riley on his other side.

"Riley Poole, Ben's 'Accomplice'." Riley even used the air quotes for emphasis as he rolled hi eyes.

"Abigail Chase, the other of Ben's Accomplices." Abigail smiled, looking up at Ben.

"Evelyn Carnahan, I'm an intelligent Egyptologist." Evelyn grinned.

"I'm Rick O'Connell, I was dragged into taking Evie to Hamunaptra, and in the end had to take out an immortal Mummy." Rick practically summed up their adventure in one sentence.

"Johnathan Carnahan, I'm not athletic but I do know how to read some Ancient Egyptian." Johnathan said, standing next to Evelyn. "Oh and I'm Eviee's big brother." He ended with a cheesy smile.

"Bruce Wayne, I'ma billionaire, and I'm the Dark Knight of Gotham, so in other words I fight crime in a bat-suit." The man, who Lily thought was fairly handsome smirked slightly.

"Lois Lane, I'm a reporter for the Daily Planet." Lois Lane smiled at the people, standing beside the man who was in a blue and red spandex suit, and a red cape.

"Clark Kent. But my super hero name is Superman. I'm from the Planet Krypton but I grew up in Smallvile, hence the nickname I earned from Lois." The last person said.

"Okay so we got that over with. Anyone know where we are?" Tony asked, crossing his arms like a stubborn five year old would.

"Stark, if knew that, then we could get out." Natasha snapped.

"I think she's a Ravenclaw. Looks like one... could be a Slytherin though." Sirius whispered to James about Natasha.

"Looks like the Room of Requirement." Remus answered Tony's question, looking around the room.

"The what?" Almost everyone in the room except: James, Lily, Sirius, Remus, and Severus asked.

"Room of Requirement, in Hogwarts. The Room that shows itself to those who need it most, or know where to look, or what to ask for. Once inside it can give anything except Food... which doesn't make sense because why would we be put into a place that can't provide food is beyond me." Lily said looking around.

"Alright. So Let's see-WATSON!" Sherlock suddenly yelled.

"Sherlock, I'm right here, why are you yelling?" Watson asked, crossing her arms, after half jumping out of her skin.

"Your doing it again." Holmes replied without looking at her as he walked off to go explore the room.

"I can't see through the walls... must be lead-lined." Clark scowled.

"Its actually Magical." James replied.

"Magic?" Thor asked slightly confused then his face lit up, "Loki can do magic."

"Loki!?" Sirius, Remus, James, Fred, and George's eyes were suddenly on the God of Thunder. Then as if planned they said, "He is our idol!"

"Uh-oh... more psychotic magic users." Tony grumbled, and Natasha sent him a warning look, and he gave her a smirk and waggled his eyebrows at her, risking it all.

"Sta-" But Natasha was cut off when Clint grabbed her arm and said, "Nat, relax."

"How do you know Loki?" Thor asked, tilting his head.

"Loki is the God of Myshcief and Chaos! Who wouldn't know him!" Sirius cried happily, forgetting entirely, and saw Remus sitting down on one of the many couches and launched at him, mid air changing into Padfoot, and landing on his friend.

"PADFOOT!" Remus yelped when the large black dog landed on him, and shoved his friend off.

"Is he a Vesen?" Nick put his hand son his hips.

"Not that I know. We can't actually change all the way. He is something else." Monroe explained.

"A Werewolf?" Jacob asked looking at The large dog that with a crack was Sirius in full clothes.

"Bloody Hell no. I'm an Animagus! Completely and utterly different. Werewolves can only change on the Full Moon, all the other times they are normal humans." Sirius defended, James and the other Witches and Wizards nodded in agreement.

"But that doesn't make sense. Jacob's a werewolf and he can change willingly." Bella argued.

"Oh right! And Vampires aren't the Living Dead." Ron snorted sarcastically.

"For your information, my family tends to not go after humans. We go after animals." Edward replied.

"Still look Cedric." Fred and George sang in a sing-song voice, while bouncing on their heels.

"So, let's try and get to know each other." Lily said trying to stop the on coming fight. "We are clearly here some how on the fact that we are all from different Worlds, the same but different so dimensions if you will call it that. Now, I'll count everyone off and then we will split into groups and learn more of the people in our groups." Lily pointed and counted each person.
