In the Helicarrier

Kaneki couldn't help but whistle in appreciation at the large ship. "Wow, so this is where my tax money goes to."

"You don't work, you rob dead people," Natasha was quick to retort.

"Not like they need it," Kaneki responds, shrugging his shoulders. He may look like he doesn't care on the outside, but in the inside, he was a mess. He was scared to meet the Avengers, too see their judging stares, to hear their loathing comments.

"Guys, meet our new teammate," Natasha introduces. The group look up at him, they were all sitting at a round table. They all looked at him in shock or in disbelief.

"Natasha, isn't he all bit young?" Steve asked, nervously.

"I'm old enough to vote, jack***," Kaneki replies, annoyed. Tony and Clint snickers at the comment and the look on Steve's face which was bright red.

"Sorry," Steve apologises.

"W-What's your name?" Bruce asked, stumbling over his words.

"Mukade," Kaneki answers.

"You're named after a bug?" Clint inquired, dumbfounded.

"His real name is Ken Kaneki," Natasha corrects, rolling her eyes. "Kaneki, behave," Natasha ordered.

Now it was Kaneki's turn to roll his eyes, "I did warn you," Kaneki reminded.

It was then that Fury walked into the room with Agent Hill. He took one look at Kaneki before offering his hand for Kaneki to shake, "Ken Kaneki, it's good to have you on board."

Kaneki shook Fury's hand before replying, "It's not like you gave me a choice."

An awkward silence filled the room, it would have gone on longer had Fury not decided to explain the mission. "Last month, Hydra attacked and raided S.H.I.E.L.D warehouses and stole dangerous plasma-based weapons. We tracked down their location and we need you to recover the weapons."

"I don't mean to sound rude but what does that have to do with Kaneki? I mean, we can handle this mission," Tony questions. "No offence but I don't think this kid can handle a mission of our level."

"Can I leave now?" Kaneki asks, instantly. 

"No," Fury deadpans. "All the entrances to the Hydra base is protected by a plasma cannon which can destroy a tank in 3.5 seconds. It's too dangerous to send one of you there."

"Then why are you sending Kaneki?!" Steve asked, bewildered.

"Because if my head is blasted off it'll grow back," Kaneki answers, bored before turning to Fury, "that's why you want me. Because I have a higher chance of surviving than these losers."

"Exactly," Fury responds.

"We are not 'losers'," Thor said, sounding angry.

"Could've fool me," Kaneki snorts, rolling his eyes. Now the rest of the Avengers were getting angry at Kaneki's bad attitude.

"Kaneki," Natasha reprimanded. 

"You guys forced me to join, as far as I'm concerned, I don't need to be your friend just listen to orders. I don't know what you expect of me," Kaneki counters. 

"Then why don't you just quit?" Steve challenges.

"Because they threatened to experiment on me if I refused," Kaneki throws back. Steve turned his glare to Natasha, he may not like Kaneki so far but that doesn't mean that he deserves to be forced into something he didn't want to do.

"Sir, we're nearing the site," an agent informs.

"Kaneki, we have a suit prepared for you, if you follow Agent Hill," Fury said.

"No need, I have my own underneath my clothes," Kaneki tells him before leaving the room to change.

"Such a wonderful ray of sunshine(!)" Tony remarks, sarcastically.

"He is beyond rude," Bruce comments.

"He has no respect for us," Thor agrees.

"Well, he's apart of the team so deal with it," Fury orders before heading down to the other agents.

"Looks like there's nothing we can do," Clint states.

"Why did you guys recruit him again? It's clear that he doesn't want to be here," Steve asks.

"We didn't have a choice," Natasha replies, "it was too risky to send one of you and we need Bruce to help dismantle the weapons immediately."

"Kaneki said if his head is blown off it'll grow back, what does that mean?" Bruce questions, curious.

"Kaneki has a very powerful regenerative ability," Natasha replies, "any wounds or injuries that can kill a person instantly can be healed in a matter of seconds for Kaneki, he won't die easily."

"How did you find him?" Thor inquired. "You would have had to seen his healing ability to know if he could survive such severe injuries."

Natasha shared a look with Clint before saying, "This isn't something that I can share with you all."

"We're nearing the site so it's best to suit up," Hill explains and the group leaves to suit up. They then headed to the Quinjet only to see Kaneki already there but what he was wearing shocked them. Kaneki was wearing a leather gimp mask with an eyepatch. The mask has a lipless mouth, showing off large, gnashing teeth which looks like it belongs to a restrained asylum monster. There were bolts sticking out of the neck which gives it a Frankenstein-like theme. He was wearing a black form-fitting bodysuit with 2 small cutouts near his shoulders and a large portion of the back cut out. Strangely enough to the group he wasn't wearing any shoes which showed off his black toenails which matched the nails on his hand. Add his pale, alabater skin, he looks like a sickly monster straight out of a horror movie.

"... wow..." Tony couldn't help but say after a brief moment of silence as the group stare in shock at Kaneki's appearance. 

The Quinjet leaves the Helicarrier and soon it lands near the Hydra base, during the journey each role was explained to the Avengers. As planned the group had to deal with the agents patrolling the perimeter. Kaneki was then to deal with plasma cannon which will allow the rest to storm the base. They landed near by and Natasa throws them all an earpiece. 

"You all know the plan?" Natasha asks and they all nod. "Great, let's go." The Avengers swiftly dealt with the patrolling agents and had reached one of the entrances to the base. 

"Kaneki, your turn," Steve orders and Kaneki shoots through the tunnel, dodging the plasma shots at the speed of light. It wasn't long till he reached the Hydra grunts and instantly disposed of them.

"It's safe," Kaneki reports and waits for the others to arrive before they lay waste to the Hydra base. They completed the mission without a hitch and went back to the Helicarrier to report to Fury.

"Now that I've done my job, could I go and never come back?" Kaneki asked, bored. He knew the answer but couldn't help but ask.

"No, you're a official member of the Avengers and you're still a liability," Fury states, immediately. "You're a danger to the public so there's no way we can leave you unchecked."

"So what you're saying is I'm a monster?" Kaneki declared.

"That's not what he means," Clint argues.

"No, it's fine. Not the first time I was called a monster," Kaneki quipped without a care. The team watched in silence, but Bruce was the one who paid the most attention. He saw the wistful look in Kaneki's eyes, the small somber smile that pained his features and had come to a realisation on Kaneki's bad attitude.

Kaneki hated himself. He hated who he was, what he became. They were both the same. The only difference was that Bruce had learnt how to live, how to live with his burden and how to use his gift to help people. Kaneki just needed to be shown the way and that was what Bruce was going to.

"Well, I'm going to train if I can't leave, so see you," Kaneki leaves the room which allows the rest to discuss in private.

"Natasha, how did you come across his healing ability?" It was more of a demand than a question.

"I told you befo-"

"Natasha," Bruce said, firmly.

Natasha sighed, knowing Bruce won't let up so disclosed the information on Kaneki, "The first report we ever had on Kaneki was from an emergency call from a group of young adults coming from a bar. They found him clawing at his own throat. The group had gotten closer to stop him from harming himself but when Kaneki saw them he ran. He was never seen again but that doesn't mean he stopped his attempts."

The Avengers really weren't expecting that answer, Kaneki was suicidal? This is a serious matter. How were they suppose to speak to Kaneki normally if they knew sensitive information like this? If he finds out they know he could either blow off the handle or just play it off.

"Bruce, what did you find out?" Steve questioned, curiously. Bruce knew something.

"I think Kaneki and I aren't so different. He has the same thought of himself as I once did about the other guy."

"Really?"

"Let me speak to him, maybe I can get him to open up," Bruce tells them. He then leaves the room to find Kaneki. He finds Kaneki throwing hits at the punching, decimating it. Kaneki takes one look at Bruce before turning back the pile of bags and hanging another on the hook.

"What do you want?" Kaneki asked as started throwing more punches at the punching bag.

"To talk," Bruce answers.

"What's there to talk about?" Kaneki scoffed.

"Natasha told me something sensitive about you," Bruce hints.

Kaneki stopped then chuckles when he realised what he was saying, "She told you I'm suicidal." Kaneki then turned to Bruce and began to taunt him, "And why are you here? To comfort me? Tell me that suicide is never the answer? Don't tell me such bulls***, you don't know anything about me."

"You're right, I don't know anything about you, I don't know anything about your past but what I do know is that you suffered something horrific and you blame yourself for it," Kaneki ceased his punching, Bruce hit the nail right on the head.

"You know, I tried to kill myself too," Bruce mentions and Kaneki, once again, pauses in his action. "I was recruited to create serum that could protect the body from radiation, the truth was that they wanted me to recreate the Super Soldier Serum. I got too cocky and upped the dosage before experimenting on myself and the Hulk was created. I ended up killing a bunch of people and hospitalised my fiancée. Her father wanted to use the Hulk for military purposes so I ran but they always managed to find me. I headed to the top of a mountain in Greenland and fired a gun in my mouth but the other guy spat it out. I was lost, didn't know what to do but in time I realised I could help people so I became a doctor. Kaneki, I just want to help you if you'd let me know."

Kaneki sighed before taking a seat next to Bruce, "Mass extermination. I come from another world where there is another species beside humans, known as ghoul's. To humanity we were the monsters under the bed because we needed to eat humans. To them we had no emotions, no feelings. That just made it easier for the CCG to kill us. I'm an artificial ghoul, a half-breed if you will, due to an accident which led to a surgery I never agreed to. I only found out about the so-called, 'surgery' after I woke up, the bastard of a doctor experimented for his own twisted needs! I remember being so terrified once I found out, I didn't know where to go, who I could talk to, I was all alone. The folks from Anteiku took me in and I found a place where I could belong. It didn't last long though, an incident happened and I left them. I abandoned them for my own selfish needs. Months later, the CCG raided Anteiku and by the time I arrived, my friends were all dead. I saw their corpses being dragged into huge bloodied piles, their eyes so cold. Every single one of them was murdered by people who simply believed that they should die just because they were born! Touka, Hinami, Hide... everyone's dead and here I am, alive and well. I'm nothing more than a murderer! "

Kaneki was sobbing into his own hands, why was he even alive? Bruce wraps his arm around Kaneki's shoulder as a form of comfort. "Kaneki, that wasn't your fault and I may not know your friends but they wouldn't have blamed you. There's nothing you can do now, the past is the past, but you can make yourself a new life. Everyone in the team has their own dark secret about their past, what's admirable is how they choose to live their lives."

"That was so heartwarming!" Tony sobbed over the earpiece.

"Tony!" The rest scold.

"You just gave us away," Clint complained.

"We just wanted to know more about you, Kaneki," Steve explains, nervously.

"So you thought spying on me was a good idea?" Kaneki questions.

"In our defence, your earpiece was left on," Tony explains.

"Still," Kaneki responds.

"We apologise for overstepping our boundaries," Thor tells him.

"It's fine," Kaneki responds, "but you're an a**hole, Stark."

"Just me?!" He says in outrage.

"Makes sense," Clint shrugs.

"Obviously," Thor comments.

"Tell us something we don't know," Natasha said.

"You deserve that Tony," Steve agrees.

"Well Kaneki, we're heading out to grab something to eat. Wanna join us?" Clint asks.

"Sure but I won't be able to consume anything except coffee," Kaneki warns.

"That's fine, let's just go," Steve said. 

"Make sure to lose the creepy mask," Tony adds.

"Fine," Kaneki agrees before heading out with Bruce to meet the others. Tony and Steve were already arguing when they got there. Kaneki figured that being around the Avengers was going to be an interesting experience for him.
