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.

The groups:

Group 1 - Tony, Harry, Remus, Peeta, Jacob, Evelyn,

Group 2 - Thor, Ron, James, Nick, Holmes, Rick

Group 3 - Natasha, Hermione, Severus, Rosalee, Watson, Johnathan

Group 4 - Clint, Fred, Lily, Monroe, Ben, Wayne

Group 5 - Banner, George, Katniss, Edward, Abigail, Lois

Group 6 - Steve, Sirius, Gale, Bella, Riley, Clark

Chapter 2

"Group One, will be in the Room labeled: Avengers." Lily ordered, pointing to the one room off to the side. "Group 2, in the Room Labeled: Watson and Holmes. Group 3, in room: Potters, Weasleys, Granger, and Snape. Group 4 will be in room: Wayne. Group 5 in room: Hunger Games. And Group 6 in room: Superman and Lane. Alright. Everyone know their groups?" She was receieved by nods and then ordered, "Off to your respective rooms, I'll set a timer and hopefully we might be able to find something and get everyone sorted out."

Everyone filed away into their respective Group Rooms...

Group 1

Group 1 - Tony, Harry, Remus, Peeta, Jacob, Evelyn

Tony, Harry, Remus, Peeta, Jacob, and Evelyn sat in the Avengers' Room, which was brightly colored in Red, Gold, Black, Blue, and White. On one of the door it had the Black Widow's Symbol, which was on her belt. They stared at each other for a good ten minutes before Harry spoke up, "So... uh... what's everyone's home life like?"

"Best you could come up with?" Remus raised an eyebrow.

"Hey! I may be the Chosen One, The-Boy-Who-Lived, and big person of the Golden Trio, but I can't think of ways to break the ice." Harry shrugged, and started drumming his wand on his lap.

"So, your a werewolf?" Evelyn asked Jacob, but no one noticed Remus pale slightly at the mentioning except for Harry, who only gave him a nod that he knew.

"Yes." Jacob hesitantly replied.

"What is a werewolf? Are they something made by the Capitol?" Peeta asked, curiously.

"The Capitol?" Tony asked stunned. "Werewolves, are vicious creatures that have to control their 'inner wolf' and go through a hard transformation every full moon. Only Dracula ever had a cure."

"That's not true." Harry, Remus, and Jacob spoke out at the same time then looked at each other stunned.

"Sorry... I am good friends with a werewolf." Harry replied looking at his lap.

"You know other werewolves?" Jacob asked, clearly confused.

"Only one. And frankly I don't feel like meeting the other ones, they were once part of Voldemort's Army. My... friend... Happens to work for the Order, or the Light, and its my side. He has to go through the trouble of loosing his job but he's still a great guy." Harry shrugged.

"Who is he?" Jacob seemed excited, "Is he here in, whatchamacallit?"

"Room of Requirement. And Yes actually he is. And he is in this room." Harry smiled at Remus, who paled considerably. "It's alright, Remus, they can't judge you considering we have another werewolf in this room."

"Why don't we explain a little about ourselves?" Evelyn asked looking at the others, clearly waiting for one of them to talk.

"I'll go!" Tony practicably bouncing around, and eating blueberries, which he kept in his pocket and decided to share with the others in his group. "I'm Tony Stark, Genius, Billionaire, Playboy, and Philanthropist. I am the owner of the Stark industries, it makes weapons. However when I was showing some of America's troops how the newest worked, we were ambushed and shrapnel tries to push its way into my heart every day... except this-" Tony taps the light source that is under his shirt, "-stops it. That led me to get onto the Iron Man suit, and eventually into turning my tower into the only tower with Green Energy."

"I'm Peeta Mellark. I'm from District 12 in Panem. I grew up in a bakery and since our District is the District of Coal Mining, I knew I would be lucky not having to go into the mines and only have to really work in the Bakery. Yeah the Hunger Games, which is litterally where our government takes 24 people from the ages of: 11 to 18, one boy and one girl from every District and put them into an Arena to fight to the death. Only one is allowed to survive." Peeta hesitated at this letting that soak in.

"But the girl, Katniss, I think it was. Said she went in to the 74th and you said so as well. So there has to be an exception." Remus pointed out and the others agreed.

"They only allowed us to both live because we threatened to eat the Nightlock, a deadly berry that would kill anyone before you even finish swallowing it. They stopped us by telling us that the Game Makers had decided to let us both win, and in that we got to go home. Of course everyone in Panem except for Katniss' family and maybe her friend's family thinks we are 'star crossed lovers'." Peeta finished.

"That most likely won't end well." Jacob grimaced at the 'star crossed lovers' part.

"I agree the Werewolf!" Tony voiced his opinion, "Romeo and Juliette didn't end too well. So I wish you both luck."

Evelyn looked at Peeta and said, "Don't worry, you'll work something out. Next?"

"I'll go. I'm Remus Lupin, and I'm a werewolf. I was an outcast until I came to Hogwarts were I met: Peter, James, and Sirius who found out my 'furry little problem' as James so lovingly calls it, and became Animagi to join me on the Full Moons. I was sorted into Gryffindor, and it wasn't until second year I realized why. It was because in the Wizarding World, and to be someone like me, it takes a lot of bravery. I was nicknamed Moony, by Sirius, who found it amusing and once they became animgi Sirius' got the nickname of Padfoot, James is Prongs, and Peter is Wormtail. We also became the Marauders and caused loads of trouble." Remus chuckled to himself at this, and Harry smiled, the werewolf fell silent.

"I guess I'll go. I'm the son of Lily and James Potter, I was born on July 31st 1980 and in October of 1981 James and Lily were killed because the Rat ratted them out. I was taken to Lily's sister's house, and I was taken in and if Sirius ever found out how they treated me he would be sent right back into Askaban. Anyway, I'm in my fifth year at Hogwarts as a Gryffindor, and I don't like my fame. Yeah it can come in handy at times but I'm not fond of it, I'd rather have a real family, and no matter how famous I am I'm never going to have known my parents. I became best friends with Ron and Hermione, and the Twins gave me the Marauder's map in my 3rd year, the same year everyone thought Sirius was out to kill me-" Harry was interupted.

"Sirius would never kill anyone! Okay maybe Snape for being a Death-Eater... and possibly most of his family for be 'inbred psychos'." Remus shrugged but then defended, "Padfoot wouldn't hurt anyone as well."

"Padfoot?" Tony looked entirely confused.

"Sirius' animagus form." Remus and Harry said together.

"I'm sorry but what is this Animagus thing?" Evelyn asked, looking at the men in the room.

"Its a Witch or Wizard, who went through the proper things and is able to change into their 'inner animal'. James is a Stag, so he would be Prongs because of the Antlers. Sirius is Padfoot, because of well he has padded feet when in that form. I'm a werewolf, so I got the nickname of Moony. Peter-"

"Pettigrew is a rat, hence the name Wormtail." Harry sourly finished Remus' thoughts, surprising Remus.

"Okay... I'll go next. I'm Evelyn, please call me Evie(?), my life is fairly normaly I mean I am the younger sister to Johnathan, so its not always the greatest thing. But I recently woke up a Mummy, who wanted to wipe out the world. Thanks to Rick and Johnathan we were able to kill it." Evelyn smiled and they all nodded, clearly deciding not to ask questions.

"I'm Jacob Black-"

"Are you related to Sirius by any chance?" Remus tilted his head slightly in curiosity. Jacob shook his head.

"Anyway, I'm a werewolf, so I'm against the Vampires and kept them in line. Bella came and everything turned upside down. I ended up working with her for a while, of course I don't like Edward that much but I help them the best I can." Jacob replied flashing a wolfish smile.

Group 2

Group 2 - Thor, Ron, James, Nick, Holmes, Rick

"What do we talk about?" Thor thundered, sitting on one of the two beds.

"Not sure." Ron shrugged along with James and Nick. Nick being completely unsure about the whole thing. Rick watched them, keeping silent. Holmes watching each of them for the longest times.

"Well. I guess I should introduce myself. I'm James Potter-"

"Harry's Dad." Ron's eyes widened, looking at the man. "Your Prongs, aren't you? One of the Marauders."

"Yep, and proud of it!" James beamed. "Anyway, I'm also known as Prongs, so obviously I'm an Animagus like Sirius."

"You're nervous." Sherlock interrupted watching the older Wizard. "Your fidgeting, and clearly want to get out of here as soon as possible. So, Mr. Potter, what are you hiding?"

James' mouth opened and closed before he ran a hand through his hair and replied, "The fact that Lily, Remus, Sirius, and I were going to go to Three Broomsticks before Lily collapsed and everything went dark for the the rest of us... Anyway, I'm a Marauder, or a Prankster, one of the four! We are the best prankster Hogwarts has ever seen!"

"Hogwarts?" Nick asked.

"Magical School for Witches and Wizards." Ron explained, "Ron Weasley, and I'm a Gryffindor, which is a bloody hell a lot better than Slytherin. But anyway I'm best friends with Harry. The youngest boy out of Seven Kids, but Ginny is younger than me so I'm second youngest." Ron shrugged.

"Molly and Arthur really had that many kids!?" James exclaimed, and Ron nodded, "Thought they were always joking when they said they had five kids to look after."

"I'm sorry to interrupt but I'm a Grimm and I wanted to know if you are a Vesen." Nick looked at James.

"A Vesen? What is that?" James and Ron asked together.

"Its hard to explain. But apparently not if you don't know what I'm talking about." Nick shrugged, "Nick Burkhardt, Portland Police Detective, and a Grimm."

"Well. Sherlock Holmes, consultant detective." Sherlock was rolling on the balls of his feet,as he watched the others, clearly taking in almost everything about them.

"This Gryffindor you speak of, I do not understand." Thor, looked puzzled, "Nor do I understand what a police is."

"Gryffindor is one of the four Houses in Hogwarts." James said and glanced at Ron but bother wizards found themselves speaking at the same time, "The four are: Gryffindor- where the brave at heart dwell; Slytherin- where cunning and ambition is treasured along with pureblood status; Ravenclaw- where only the smartest go; and finally Hufflepuffs- loyal to the end."

"No what is this Police you speak of?" Thor looked at Nick, who hesitated.

"We enforce the law, and arrest the bad people." Nick replied, clearly struggling with how to describe police.

"Well, I guess I should introduce myself. Rick O'Connell, and I killed a thousand year old Mummy that tried to take over the world when we read from the Book of the Dead." Rick finally introduced himself, and waited for the confusion but none came. They all jumped when Thor spoke next.

"I am Thor, son of Odin, and God of Thunder! I protect Midguard, against other realms." Thor bellowed this, and hence causing them to jump. Sherlock, was the only one who didn't jump, as it was clear he wasn't surprised by the largest man's outburst.

"Okaaayyyy then. So, let's see, why not play a game!" James grinned, and Ron internally groaned, since the same look that was on the Twins when they were threatening to do a prank happened to be on James' face now. And it was clear no one else know what the grin meant.

"Alright. And what game shall we play, Mr Potter?" Sherlock asked, raising an eyebrow.

"... How about Tray Surfing?" James beamed, it had been something that the Marauders LOVED when they were in Hogwarts.

"We don't have trays or tables to surf on." Ron pointed out, stubbornly, but James waved him off and transfigured a couple of blankets into trays.

"You don't need a table to surf on for Tray Surfing, Ron, you simply get onto the tray and hope for the best!" James said after charming the trays and jumping onto one of them, instantly floating a good three feet in the air.

"You mortals think of strange things to do." Thor laughed, but joined the fun by jumping onto a tray as well, while Ron did the same. Sherlock watched as the three took off around the room, which suddenly seemed a lot larger. He then saw that Rick had joined them. Of course Sherlock knew it would be kind of entertaining to watch but wanted to at least attempt it so he jumped onto the last tray and took off with them. James transfigured something into a ball and they were throwing it around to each other to see what they could all do. Sherlock, was however, still trying to figure out how and why everyone was here.

Okay so end of this chapter. Sorry for if any characters are OOC, I'm brilliantly smart like Sherlock nor am I am a badass prankster like James. I also tried to get Remus to be somewhat quiet and not talk much. But not sure, he is a difficult character to write, btw.

Next chapter has Groups: 3 and 4 in it!

Thanks for Reading!
