gbbz : Thanks.

sprigganrayearth : A bit more than I should.

zugrian : I am British actually (not even posh) so thanks for that piece of information.

DZ2 : An unintentional doctor who reference.

Blaze1992 : I haven't actually had Harry use his rage mode yet, I was originally going to have him use it against the Destroyer but I decided to save it for later.

Spiderthatreads : I guess that means I own your life now, give me one million of your pounds puppet.

Miles VorKosigan : Well first of all the canon Harry Potter used an unforgivable like twice. Second of all the point is that you don't necessarily have to be evil to use them, just have to have sufficient emotions required. Now this Harry who has been in a war where he has been throwing around curses like these for years, he's used to the spells so many times that it doesn't even bother him anymore. The same reason Voldemort used them, because they're pretty effective so long as they're not thrown at Harry Potter, even then they are mostly effective.

Chapter 20 -

"You wanted to see me?" Grim asked as he entered Fury's office by teleporting in, he was of course invisible until after he had entered the office and confirmed that it was just him and Fury, which combined with his silent teleportation made it look like he simply appeared. Probably unnecessary but he had learnt early on that appearances can be important. He saw Fury sitting behind his desk and was a little surprised that he didn't have Coulson and Hill wit him.

"You can drop the costume." Fury said in a tired voice, Harry's suit dissolved away, leaving Harry standing in black trainers, blue jean, a grey shirt and a black jacket.

"You sound like you've had a great day." Harry said in a sarcastic voice.

"A brilliant one." Fury said in a dry voice before his voice returned to his usual serious one. "Can you track Barton" Fury asked suddenly.

"More than likely but a good question that I would like to know the answer to is why you want me to track Barton in the first place?" Harry raised an eyebrow at Fury. "Because, believe it or not, it doesn't sound good when a director of a government agency asks a wizard to find one of their best and most deadly employees."

"Barton has been compromised." Fury admitted, though he looked like it pained him to do so. "By somebody named 'Loki'."

"Loki?" Harry blinked. "Oh for fuck sakes, please tell me you don't mean the brother of Thor. It's not that Loki is it?"

"We suspect it is the very same." Fury nodded. "He tapped Barton's chest with a tip of a scepter, the next thing I know Barton's treating Loki like he was his damn boss."

"Mind control." Harry muttered under his breath before looking at Fury. "Describe it, how did Barton act? Slow? Did he always wait for orders before doing anything, even speaking?" Harry asked, giving Fury his full attention.

"No, he talked and acted like he usually did." Fury frowned as he shook his head. "It was more like...Loki had somehow managed to change his perspective. I am not sure how fully under control he is."

"Why?" Harry asked.

"Because he shot me but he didn't go for a headshot," Fury answered. "he could have, easily, but he didn't."

"You were wearing a body vest?"

"Naturally."

"Hmm, I will get a sample of Barton's blood and..."

"There's a problem with that," Fury interrupted. "Barton knew about your ability to track people through blood, that's probably why this morning I received reports of our medical facilities being attacked. It wasn't just the the blood wasn't destroyed, the database was messed with so information on which blood belongs to who is probably wrong until we fix it."

"Well that's great." Harry rolled his eyes.

"Is there anything else you could use to track him? Like a hair or one of his arrows?"

"Not as effective," Harry shook his head. "if he was close range then great but it's not as effective long range since he is not magical."

"Hmm, I've sent some information to your Shield tab," Fury said, referring to the tablet that Fury had given him when he had joined. "all the information we have." Fury added, Harry mentally translated Fury's words into 'all the information we think you should know'. "I would also like you to accompany Agent Romanoff on a mission."

"Kill? Capture?" Harry asked.

"There's is someone that we would like to bring in, peacefully, we need his help and would like it if he willingly helped us out. All the information will be on your tab."

A short while later Harry was at home, rubbing his eyes, tempted to smash his tablet and throw it out of his window. He had just read up on all the information Shield had about the tesseract, or at least all of the information they had given him. Harry trusted Fury, to a degree, he doubted he would ever one hundred percent completely trust him but he respected him enough to not read his mind at every opportunity. Although now he was admittedly very tempted to do so.

The tesseract, a bright blue cube, was what Fury wanted back. Apparently Shield wanted to use it as a power source due to the fact that they believed it could be the key to unlimited energy. Harry knew that it was probably more than just that, he had learnt long ago to never take people's words as absolute truth. Harry believed in 'trust but verify', and since he didn't fully trust Shield that meant more verifying.

Harry also read up on the information of the other people Fury wanted to bring in, one of them was Steve. Harry knew that Fury had some reason for bringing Captain America in beyond an extra set of enhanced hands. Then there was also Stark, admittedly Harry understood why he wanted to bring Stark in. The man's Iron Man suit was an incredibly advanced and brilliant bit of tech, and the man behind its creation was a genius, no matter who you asked.

There was information on Barton and Natasha but Harry had skipped that as he already knew all he could about them. There was also information on Loki, limited information but better than nothing, the information included various myths and legends about him, including myths about him being the father to a snake big enough to wrap itself around the world. If that existed then Harry wouldn't really mind meeting it, providing it didn't try to eat him. But Harry doubted it, that sort of thing was kind of hard to miss, especially in a world as technologically advanced as this one. He didn't completely dismiss the possibility, mostly so he didn't look like an idiot in case he was wrong. There was also information on Thor, myths, stories and guesses, but the confirmed facts were stuff that Harry already knew.

Then there was information on Bruce Banner, a genius who apparently had seven PhDs, which Harry personally thought was a bit overboard. The man seemed to specialize in radiation, specifically gamma radiation, which was more than likely why Shield wanted him as the tesseract produced low levels of the stuff. Though Harry knew that was not where Shield's interest in the man ended, there was also the fact that the man possesses the ability to turn into an enormous green rage monster.

'The Hulk' was the name they had given Banner's other half, the Hulk was a green skinned being who stood at an estimated eight to night feet tall and was able to pick up and throw cars like they were footballs. His strength was insane and so far a limit hasn't been discovered, not thanks to a lack of trying since the army was very insistent on trying to catch him, either to kill him or study him, Harry was leaning more to the second. It was hypothesized that the Hulk's strength is related to his/Banner's emotional state, meaning it would be good to keep the guy as calm as possible.

Hulk had also fought a similar creature called 'Abomination', the two had destroyed a large amount of Harlem during their fight, though Hulk had won in the end. In a way it sort of reminded him of Remus Lupin with his 'furry little problem'.

Fury wanted Natasha to try and convince Bruce Banner to work with them but he also wanted Harry to come in case Bruce decided to let Hulk take other the negotiations. Which meant Harry had to be ready to fight the Hulk if it came down to it. 'Wouldn't that be fun?' Harry thought sarcastically.

Bruce Banner was currently in India, he had spent a lot of his time healing people, it was a great way for him to not only gain money but also help people. He never stayed in one spot for long, that would just make him easier to be found. As of the moment he was being guided towards a house by a young girl who had told him that her father was sick. She led him into a small brown, wooden house, as soon as he got into the house he looked around to see if he could find the father but saw nobody.

In fact that house looked suspiciously empty, he turned to look at the girl and saw her quickly exiting the house through a window. He was about to follow after her but stopped when he realized that he was not in fact alone.

"You should have got paid upfront Banner." Bruce said to himself, realizing that he had been tricked.

"You know, for a man who's supposed to be avoiding stress, you have picked a hell of a place to settle in." Natasha said as she walked into the room, making herself known.

"Avoiding stress isn't the secret." Bruce replied as he turned to look at her.

"What is it? Yoga?" Natasha joked.

"You brought me to the edge of the city, smart." Bruce commented as he looked out the window. "I assume the whole place is surrounded."

"Yes." A male voice replied, Bruce looked back and saw Grim standing in the corner, his cloak covering his whole body.

"Who are you?" Bruce asked in a calm voice.

"He's just basically here in case you decide to go green." Natasha explained.

"Who are you? Both of you." Bruce said as his eyes glanced between them both.

"I am Natasha Romanoff," Natasha answered before gesturing to Grim. "his codename is 'Grim'."

"And your actress buddy?" Bruce asked as he gestured to where the girl had left. "She a spy too? They start that young?"

"I did." Natasha replied.

"Are you two here to kill me?" Bruce asked. "Because that's not going to work out for everyone."

"If we wanted to kill you, then you already would be dead." Grim responded.

"You do know who I am, right?" Bruce asked.

"Yes, I also know how to remove your head in under two seconds, so if you think you can transform quicker than that then try it." Grim replied, his green eyes locked on to Banner.

"Easy," Natasha said in a calm voice. "neither of us are here to harm you," She said to Banner. "We are both here on behalf of Shield." She said, Natasha and Grim watched as recognition hit Bruce.

"Shield," Bruce said quietly. "you don't look like a Shield agent." He said to Grim.

"He's not," Natasha said with a small shake of her head. "he does some work with Shield but he is not an agent."

"So the cloak and hood aren't the latest uniform?" Bruce said in a jokey tone before his voice got more serious. "how did they find me?"

"We never lost you doctor," Natasha smiled. "we even kept some other interested parties off your tail."

"Why?"

"Nick Fury seems to trust you." Natasha said with a small shrug. "But now we need you to come in."

"And what if I say no?" Bruce asked, raising an eyebrow.

"I'll persuade you." Natasha said as Grim summoned his wand into his hand, the act covered by his cloak.

"And what if the other guy says no?" Bruce asked.

"Then it'll be my turn." Grim replied. "I spoke with Fury, his words were 'we need his help and would like it if he willingly helped us out'. We're not going to force you to come with us, and we won't take physical action against you as long as you don't take physical action against us. Besides, you've been keeping the 'other guy' locked away for a better half of a year, I doubt you'd want to let him out now."

"Hmm," Bruce hummed softly as his eyes looked around and stopped on a small cradle, he gently pushed it before speaking. "I don't every time get what I want." He said, what he was implying was not lost on Grim or Natasha.

"Doctor, we're facing a potential global catastrophe." Natasha said as she pulled her phone out and sat down.

"Oh those I actively try to avoid." Bruce joked with a small smile on his face. Grim was quite tempted to smirk at the joke but held himself back, even though nobody could see his face.

"This is the tesseract," Natasha said as she showed him a picture of the tesseract on her phone, she placed the phone down on a table and slid it ahead for Banner to pick up. Bruce placed his reading glasses on and picked up the phone to look at the picture. "it has the potential energy to wipe out the planet."

"What does Fury want me to do? Swallow it?"

"He wants you to find it, it's been taken." Natasha replied. "It emits a gamma signature that's too weak for us to trace, there's nobody that knows gamma radiation like you do. If there was then that's where I'd be."

"So Fury isn't after the monster?" Bruce asked in a skeptical voice.

"Not that he's told me."

"He tells you everything?"

"He doesn't," Grim said, drawing Bruce's attention. "Fury keeps secrets but he doesn't plan to harm you."

"And how do you know?"

"Because Fury knows that I won't like it and he knows that I am someone he doesn't want on his bad side." Grim replied as his green eyes locked onto Bruce's.

"And what happens if Fury's on your bad side?" Bruce raised an eyebrow, he looked down and shook his head before looking up. When he looked up he jumped back in surprise when he saw Grim was no longer standing there. Bruce took a step back only to feel his back press against someone, Bruce quickly turned around and nearly fell backwards in surprise and would have if not or Grim catching his arm.

"Nothing he'd like." Grim whispered.

A.N: Short chapter I know but I'll try and make the next one longer. Next chapter should have Harry's first meeting with Loki, hope that goes well. Thanks for reading and feel free to leave a review.

Omake 1:

"Just like Budapest all over again." Natasha said.

"You and I remember Budapest very differently." Barton commented as he fired another arrow.

"Oh for god's sake! Just tell me what happened!" Harry yelled.

Omake 2:

"Alright Thor," Harry said. "you need to remember to say 'Yeet' every time you throw Mjolnir."

"But why?" Thor frowned.

"It gives it extra power." Harry answered.

"Really?"

"Yeah, watch this." Harry said as he picked up a cup. "Yeet!" Harry yelled as he tossed it and it hit Bruce on the back of the head, causing him to fall down the stairs.

"Hulk smash!" A roar was heard a few seconds later.

"Oh yeah, deal with that please." Harry said as he tapped Thor on the shoulder. "thanks." He smiled before teleporting out.

Omake 3:

"Natasha, what's your status?" Harry asked into his communication device.

"Single." Natasha replied.

"O...kay."

"Also stabbed but I think single needs to be corrected first."

"Wait you're stabbed?"

"Only twice, now how about a night out this Saturday?"

"Damn it Nat, get some medical help!"

"Fine...but then a night out?"

Omake 4:

"I told you you would pay." Thor growled as he pushed Stormbreaker into Thanos's chest. Thanos, despite being deep in pain and very tired, looked up.

"You...you should've..." A smile appeared on his face. "...you should have said 'yeet'!" Thanos quickly snapped his fingers using the infinity gauntlet.

"No!" Thor cried.

"Damn it Thor!" Harry's voice was heard.
