Hello! So I decided to write the first chapter of this and see how it goes! Hope you like it and enjoy! :D

Loki looked down at the Tesseract in the container Thor was holding out for him to take. He grabbed the handle and watched as Thor nodded to his friends then turned the handle he was holding. Blue light erupted out from the Tesseract and wrapped itself round Loki and Thor. All of a sudden sparks started to fly off from the centre of the Tesseract; Loki looked up wide eyed at Thor who looked bewildered as well. Just as he thought it couldn't get any worse Loki started to feel burning on his right hand. He looked down and tried to take his hand off the handle but couldn't, he looked at Thor who by the looks of things was having the same problem.

'Something's wrong!' shouted Steve trying to get a better look at the two but was blinded by the blue light suddenly erupting everywhere.

'No!' said Tony sarcastically and turned around to look at the equipment which started to beep. Bruce and Selvig who were stood either side of Tony did the same.

'The energy readings are off the chart!' said Selvig turning the monitor for the other two to see.

'We need to get them out of there' said Bruce turning around to look at Loki and Thor.

'What's wrong?' asked Natasha as she, Clint and Steve walked up to them.

'There seems to be something wrong with the Tesseract!' said Bruce looking at them.

'What's that?' asked Clint pointing to one of the monitors.

'Sciency stuff now move out of the way before-' Tony grabbed Clint's arm as he was about to touch it 'Before you break something. Now bird boy let grownups work!'

Loki shut his eyes. The pain on his hand was unbearable. He heard those 'Avengers' running around trying to figure out what was wrong. Hurry up! Loki thought.

'Brother?' Loki opened his eyes and looked at Thor. 'Do not worry! My friends are trying to solve the problem!' Loki rolled his eyes and he felt pain jolt up his arm. Thor sighed. His hand too was burning but right now his main priority was Loki. Yes he might have tried to subjugate Earth but he was still his brother, his little brother. The one he swore to protect which he had failed at. He winced as the pain started to increase and could imagine Loki was going through the same. 'I promise you I will get you out of here!' He watched as Loki started to wince as the burning increased. He brought Mjonir up and before he could hit it the light faded and the burning stopped. He looked at Loki and saw relieve on his face. They both let go of the handle and it dropped to the floor. Thor looked down at his hand and found it bleeding and blistering, he noticed Loki's hand which looked the same. He looked up to Loki's face again and found his face extremely pale. 'Loki?' he saw Loki stumble and he dropped Mjonir and caught him. 'Dr Banner!' Bruce turned around and ran over to them.

'Lay him down on the ground' Thor did as he was told and watched as Bruce took Loki's wrist and felt his pulse, he turned to Tony 'We need to get him to a hospital'

'On it!' Tony pulled out his phone.

'Is this really necessary?' whispered Clint to Natasha. Natasha shrugged her eyes not leaving Loki. 'Why should we be helping him? He deserves to suffer'

'I'd suggest keeping that to yourself bird boy' said Tony behind him making him jump.

'Why?'

'Well Loki might be some crazed super villain but he's a crazed super villain with Thor as his brother! If we don't help him well I don't want to be on the other end of that hammer of his if you get my drift' he nodded then walked off.

'He's right Clint' said Natasha eventually.

'Oh thanks Tasha. That bastard deserves everything he gets'

'I know that Clint but that bastard is Thor's brother. And like Stark said. He's going to be pissed if we don't help him. And imagine what he'll be like if he dies? I agree with Tony, I don't want to be on the other end of his hammer'

'Then what do we do?'

'We do what we can to help then the faster Thor can get him away from here!'

'Fine! I don't like it though!' he said sighing.

'I know you don't but you'll be fine, you've been through worse' she finally broke her eye contact from Loki and looked at Clint.

Loki attempted to start coughing but that stupid muzzle was stopping him from doing that and breathing properly. He hated it. They were apparently meant to do the good thing! He was choking and they were just stood there.

'Brother, just stay calm! Help is on the way' Thor said bending down next to him. Stay calm?! I am dying and you want me to stay calm? Ever thought of taking this damn muzzle off to help? No because you are an idiot Thor! As is everyone else here!

'Here' said Steve handing Bruce a medical kit. Bruce nodded and opened it up. He took out a device and wrapped it around Loki's arm.

'His blood pressure is too low' he said looking at the readings.

'What does that mean?' asked Thor looking at Bruce.

'It means he either has an eating disorder, hormonal abnormalities, been exposed to a high dose of toxins or haemorrhaging. My best bet is the last one'

'And what does that mean?' asked Thor clueless.

'It means he's bleeding out somewhere. You need to help me take off his clothes' he said putting on some gloves.

'Excuse me?'

'I need you to help me take off his clothes. His armour. I need to find out where he's bleeding out and stop it'

'Listen to him Thor, he knows what he's doing' said Natasha patting him on his shoulder. Thor nodded and helped Bruce take off the top layer of Loki's clothes.

'How long does it take you to get dressed in the morning?' asked Tony walking over.

'A while' grumbled Thor ripping through Loki's tunic. His chest was covered in bruises and blood was gushing out everywhere. Thor thought he was going to be sick. Bruce located the wound and pressed down hard causing Loki to scream in silence.

'Puncture wound…Sorry' said Bruce looking to Thor who looked back in confusion 'I did this. The other guy did this to him'

'No you didn't' said Natasha bending down next to him. 'See these wounds' she pointed to the hole in the lower part of his body 'these are fresh. Whoever did this, did it recently'

'But Loki has been under lock and key since we caught him. Nobody has even touched him' said Steve.

'What she's saying is' said Clint walking over to them 'that the wounds are fresh. She's right in it wasn't you Banner. If you did this then he would have been dead long ago!'

'What are trying to imply?' asked Thor looking at them both.

'I think they are trying to say that someone walked up to Loki whilst he was stood here and stabbed him?' asked Steve.

'Yes' said Natasha

'It does seem the only explanation of all the facts!' said Clint.

'Wrong! It's one possible explanation of some of the facts!' said Tony 'But better luck next time bird boy!'

'Give us your theory then!' snapped back Clint.

'Don't you think we would have noticed someone walk up to Loki and stab him?'

'He has a point' said Steve.

'Tony where is that ambulance?' asked Bruce pressing down on the wound again.

'On its way Brucie boy!'

'Brucie boy? Wha-? Never mind.. Right Thor I need you to press down on the wound. Ok?'

'You think that's a wise thing to do?' asked Tony.

'I'll do it' said Steve kneeling down next to them. When Bruce moved his hands out of the way Steve put his down. Bruce looked in the box and found a bottle with clear liquid in and a syringe.

'Loki I'm going to give you something to help with the pain' he brought up Loki's sleeve and injected him with the painkiller.

'Thor?' asked Natasha walking over to him. She saw the shocked look on his face and brought him up to his feet.

'This is my fault'

'Thor listen! This is not your fault!'

'I'm meant to protect him and.. and'

'Selvig!' shouted Natasha. Selvig who was studying the Tesseract on the monitors turned and walked over to Thor 'I think he needs to sit down for a moment' he nodded and grabbed onto Thor's arm and pulled him away from Loki.

'Tony I swear to god if that ambulance is not here in the next minute-' said Bruce looking up at him.

'Woah woah cool it big guy! Don't go jolly green giant on us!'

'Isn't that sweetcorn?' asked Bruce.

'You know wouldn't it be better if you took the muzzle off?' asked Clint. They all looked at him. 'What? You want to help him right? Well I personally think that having that thing on isn't doing him any favours! But if you don't want my opinion then fine!' he snapped.

'He does have a point' said Steve

'Whose side are you on exactly?' asked Tony.

'He's right. Take it off' said Bruce getting some swabs and started to clean up his chest. Tony bent down and unlocked the mask and placed it down on the floor next to him. Loki took a deep breath like he had never tasted air before.

'Fi-na-ally' he managed to say. He could finally taste fresh air and he could breathe properly well nearly.

'Someone should call Fury about this' said Steve.

'Oh of course! I forgot! Oh hello there Director Fury! Yeah our vacation hasn't started yet! Mainly because our prisoner who we were meant to protect is having a cardiac arrest!' shouted Tony.

'Stark we get the point' sighed Natasha.

'Tony!' shouted Bruce

'Yeah?'

'Ambulance?'

'Look all I know is that it's on its way!'

'No it's not'

'Who said that?' asked Tony looking round.

'I did' said a man suddenly appearing in front of them. Natasha and Clint reached for their weapons immediately and had them trained on the mystery man. 'Oh there is no need for that! I'm not going to hurt you! I've come to help you!'

'Who are you?' asked Natasha.

'My name is irrelevant. What really important here is Loki. Well not this Loki, well technically this Loki but not yet!'

'You speak in more riddles than I do! Explain!' said Tony.

'If you want to live then you must all come with me!'

'And why would we do that?' asked Clint

'Because if you don't you'll die'

'Are you threatening us?'

'No. I'm just merely stating that if you don't come with me now then you'll all not only die but neither exist!'

'What?'

'Exactly! I'm not trying to harm anyone! I'm trying to save you all! Well getting you lot to save us all actually!'

'Why do you need us?' asked Steve.

'Well you are the Avengers!'

'What does this have to do with my brother?' asked Thor emerging into the conversation.

'How long have you been stood there?' asked Tony.

'Approximately 5 minutes and 34 seconds in counting' said the man.

'How do you even know that?' asked Tony.

'Time!'

Time?'

'Yes! Time is erasing itself! This universe is falling apart!'

'But how is that possible?' asked Bruce.

'I bet it has Loki's name written all over it' said Clint.

'Actually it wasn't Loki's fault at all! He may have participated in some of the reasons why this future is erasing itself but that's because of the beings who caused that to happen!'

'So what do we do?' asked Thor.

'In order to save the future, you must first save the past!'

So there you go! First chapter up! Oh and I should say that I am currently working on a fanfic with one of my friends and that will be a Thor/Avengers/Batman crossover! The main characters will be Loki and Crane! Lets just say I don't think Loki will be underestimating the good doctor any time soon! :D So this is just something I've been wanting to write down! Hope you liked it and please tell me what ya think by reviewing! Until the next time! :D
