At last, we finally reached the thing that most of you wanted. Killua time with Shield, this is going to last for a little while. Yes, this is going to be a whole arc, while this chapter alone here is just the Flashback of what he has done while Gon, Kurapika and Leorio were busy with the X-men, what has Killua been up to it. I know that most of you love Killua, so here we go. Its going to be a while to get back with Gon and the others, so its going to be Killua and the Shield agents. Now enjoy.

Flashback time.

Killua was just signed up as a shield soldier in training. With a ton of track advises planted in his body, plus a lie detector also planted in his body. That kid was not going anywhere.

''Ok Zoldyck, this is your first day at training. Are you prepared?" Asked Nick Fury.

''Yeah Yeah, don't worry Fury.'' Said Killua.

Fury didn't like that easy go lucky attitude, that kid would be in hell for a long time.

''You will be staying with Hill, Coulson, Dugan and Carter. They are the ones that studied you the most, so I trust them to look over you.'' Said Fury.

Killua saw the four agents looking at him. Coulson had a smile, Hill looked furriated, Carter had also a smile and Dugan just chuckled.

''You are all my babysitters while I am stuck here?" Asked Killua.

''Yes, break any rules and you will be punished.'' Said Hill.

''Its not our intention to train a 13-year-old, but we can try our best.'' Said Coulson.

''You seen pretty chilled so far.'' Said Carter.

''I have been to all kind of training before. Once I had to stay in a box for four days with no water or food, I had to eat rats. Sure, killing rats is easy, but eating then is not.'' Said Killua.

The agents only looked at Killua with a look of horror and confusion, they saw his medical results and it was a miracle that he could still walk.

''You are messed.'' Said Dugan.

''You haven't seen anything.'' Said Killua.

Soon his training begin and each one of the agents would handle one part of the regime.

Hill

''Hil make sure that he does his regular training exercise. I want to see what he can handle.'' Said Fury.

''Sure, be ready you little freak.'' Said Hill.

''Ok you crazy woman.'' Said Killua

Soon they all went to a field where Maria would track Killua resistance and heart beats, knowing what he could handle.

''Ok first, lets see how long you can ran of 200 meters?"' Asked Hill.

Killua soon prepared himself as Maria got a gun.

''Here and…GO!'' Said her

bang

Hill soon saw a blur coming out of Killua spot and soon he was at the 200 meters mark.

''1.31 seconds!'' Said her in shock

''What can I say? I was always fast.'' Said Killua.

Maria looked at those numbers in shock, this broke any record hold by any human member of Shield.

''Ok, this will be fun for congress.'' Said her nervous.

With Coulson

''Ok Killua, I want you to do the basic regime training. You know pushups, squads and sit ups, the usual.'' Said Coulson.

''Sure, there is nothing wrong with that.'' Said Killua.

The boy soon started to make his trainement. The goal was 100 of each and Killua ended those in less than a minute.

''Ok, I am done.'' Said Killua.

''Already…how?" Asked Coulson.

''I have a good metabolism. Not as good as my older brother or my father, those twos could do all these stuffs in less than 10 seconds.'' Said Killua.

''This is amazing.'' Said Coulson recording everything.

''Yes, you guys should teach to your students or soldiers whatever. Tell me, is this the only place you train people?" Asked Killua.

''Actually, we used to have a school for Shield agents.'' Said Couslon.

''Where?" Asked Killua.

''New Jersey. Ever heard of it?" Asked Coulson.

''sounds like a really weird place.'' Said KIllua

With Carter

Sharon was training hand to hand combat with Killua, she was one of the best to handle that sort of things, but the ex-assassin had a trick or two hidden on his sleeve.

''Ok Killua, I am going to attack you. The task is not letting me hit you in the nose.'' Said Sharon.

''Alright.'' Said Killua.

The training section soon began, and while Sharon was skilled in hand-to-hand combat, Killua was able to handle those punches like ti was nothing.

''Nice job, you are very good.'' Said Sharon.

''You have seen nothing.'' Said Killua.

Soon Killua started doing the Rhythm Echo, much to Sharon horror. At first, he was walking silently and soon he was gone.

''Where did he go?" Thought Sharon in horror.

''Got you.'' Said Killua appearing behind Sharon and doing a judo move on her.

''Argh.'' Said her in pain.

''Nice grip for a brat, wouldn't you say?" Asked Killua with a smirk.

''How did you do this?" Asked Sharon.

''Is an old trick that my family learned for generations, I had to learned it or else I would get more torture to myself. What do you think? Pretty amazing, isn't it?" Asked Killua.

Sharon was a little horrified by that. It was almost like Killua made several decoys and all walked very silently towards her, and later he vanished in tin air. That was some high-level training regime right there.

''This was nice but promised me to not do that while we are sparing.'' Said Sharon.

''Ok.'' Said Killua.

Sharon soon got back up and they were going back to training. She hoped that this technique was difficult to learn, because if not the government would weaponized the hell of it.

''He truly is gifted, but I hope this doesn't fall in the wrong hands.'' Thought her.

With Dugan.

The two were in an open space, mostly because they need it for their shooting sections.

''Ok Young man, think you can handle a gun?" Asked Dugan.

''Alright, I never had one of those before, but give me that.'' Said Killua.

Killua was excited to finally shooting something, he wanted to look cool and imagine that he was shooting Illumi head.

''Go on.'' Said Dugan putting a target and Killua soon shotted.

Bang

''What? I missed.'' Said Killua missing the spot.

Bang

''Again.'' Said Killua missing the shot.

Bang

Killua wasn't getting anything right, it appears he was horrible at shooting

''Ok, I think we had enough.'' Said Dugan trying to get the weapon out of Killua hands.

''No, I want to try hit that stupid target!'' Scream Killua.

After 2 hours later

''Come on!"' Scream Killua getting more ammunition, he didn't even come close to the target.

''Kid lets go. We are going to miss lunch time.'' Said Dugan.

Killua tossed the gun to the ground and storm away all angry.

''he has tantrum issue. Better to keep an eye on that.'' Thought Dugan.

At the end of the day.

Fury was on in his office looking at some recent files recording the X-mens, Fantastic Four and the Avengers, as well all the others super people that seen to pop out everywhere. Before he could read the file someone knock on his door.

Knock Knock

''Ok come in.'' Said Fury.

Soon Hill, Coulson, Carter and Dugan all storm in and all of them have ton of information regarding Killua.

'Director Fury, that kid is like a bullet.'' Said Hill.

''He already did the regime trainement of three whole days in my hour all alone.'' Said Coulson.

''He has a lot of dangerous move.'' Said Sharon.

''He is a sore looser.'' Said Dugan.

The four agents kept talking nonstop, that was until Fury lost his cool.

''OK SHUT UP!'' Scream Fury.

The general soon saw his man and women all get more calm, and soon he started talking.

''Ok, from the beginning.'' Said Fury.

The eye patched general heard all of one day of Killua training, so far, he could say he could be equal of danger as the Black Widow. That means Killua should be watch all the time and if something goes wrong, he should send him away.

At killua quarters.

Killua was reading some weird comic books that this place had, it was the only thing he had to entertain.

''Ok, just a few more days and I will get my TV.'' Said Killua while reading

He was having a good time in there, but he was missing Gon there with him.

''I wonder if Gon would like this training section. I bet he would have a blast with those.'' Thought him.

Killua soon decided to sleep, tomorrow he would be out to train again. This training wasn't as bad as the one that his family made him go through, but it was still hard. Whatever it took to find Gon and the others, he would do it.

Ok this will be the first part. This is the flashback; next one is the present of the current situation. In my head has been over 10 days since the hunters arrived at Bayville and overall the Marvel world, I think this is enough time to get use to the place. I am using Killua side to get in touch with some stuff that would be later introduce in future chapters, but also introduce some other people. Just wait, soon we will meet someone amazing or some fantastic people. Ok, bad puns sorry bye.
