I am going to give some idea of what kind of world this crossover is about. At first I wanted to just Thanos and his man, but I then realized that I need it to make more sense so I need it to put more elements to make this story to work. Now one thing, no avengers there won't be any super hero of the avengers, the rest I will do it. Now enjoy.

On I-Island

David Shield the renowned scient that received the Quirk Nobel prize was the selected one to be the first scientist to take a closer examination of the mysterious ´´Cube´´ element that has been on observation for decades.

He was on his office doing some research while his assistant with green hair and purple eyes knock on his door.

''Director Shield?'' Asked the purple eye also known as Rohan.

''Yes?" Asked David.

''The board is asking for the temperature of the cube. They want to know if its is on perfect state for the upcoming research.'' Said Rohan.

''Sure, come with me.'' Said David.

The two soon went to the room where the cube was. They put masks, glasses and gloves all the need it procedure to make this examination safe.

''Look at this. Finally, after decades we will discover what is the secret of this thing.'' Said David.

''Yes, it said in the file that it was found on the ocean?" Asked Rohan.

''It was found on the Artic Ocean. Some fisherman was catching some fish and caught this was off guard, last thing they knew most of the crew was evaporated it.'' Said David telling the story of the cube.

''So this thing might be a problem for the human race?" Asked Rohan.

''Yes, but if we take certain caution, we might find something like the cure for cancer or infinity energy.'' Said David enthusiastic.

''While I love your enthusiasm director, lets take a deep breath and see what is really inside.'' Said Rohan.

''Rumor has it that this might take people to different dimension.'' Said David.

''Wow talk about something that geeks and nerds would love it.'' Said Rohan with a smirk.

''Because it might a gate for a new era for discovery and I can't wait to test it.'' Said David.

''You are really starting to creep me out director.'' Said Rohan worried.

'Sorry, most of the staff had been avoiding me because of that.'' Said David.

The two kept looking at the cube as something of out of world. However, the feel of wonder was cut because they heard what it sound it like gunshot.

Bang Bang

''What is that! Are we under attack? Should I call a pro hero?" Asked Rohan.

''Oh is ok, I know who is shooting.'' Said David.

''Who is shooting?" Asked Rohan.

''My daughter.'' Said David much to Rohan confusion.

''Huh? Melissa Shield the gifted quirkless student? She is into guns now?" Asked Rohan.

''Well after the incident she decided to train as much as she can. I begged her to use some modern device but she insisted and training with guns. I don't know why she would do that? Maybe she takes that after her mother.'' Said David.

The two soon kept hearing the shots and decided to see what the blonde teenager was doing.

Bang Bang BANG BANG

The two soon enter the training area where Melissa was doing a great job. Excellent shots and prefect composition.

''Nice, 5 times in a row.'' Said her seeing her shots.

''Hey my little gunslinger.'' Said David

''Hi daddy, hi mr Rohan.'' Said Melissa.

''Hey Melisa, so I see that you decided to use guns now?'' Asked Rohan.

''Yes, after that huge battle I wanted to learn how to defend myself. Nobody is going to mess with a woman with a gun, especially one that knows how to shoot.'' Said Melisa

Melisa has been doing this training for months now. She study on how to fire guns, how to use them and what are the best types. She basically did huge research on guns.

''i thought you were going to do something like Gymnastics or whatever.'' Said Rohan.

''Yes, I am doing gymnastics and I am doing great so far.'' Said Melissa.

The scientist was shocked by this. Gun training and doing gymnastic this girl was something.

''You are also doing gymnastic?" Asked Rohan

''Of course this is the best solution. I mean I can handle any mugger and be on the best shape to run.'' Said Melissa.

''Well I don't approve irrational thinking but I know you can handle these things.'' Said David Shield.

''Are you the one that encourage her?" Asked Rohan.

''Yes, but she decided to go in other styles.'' Said David.

''Don't worry I know how to look out for others and leave the gun on safety.'' Said her.

''Well I am glad that you are doing fine also.'' Said Rohan.

''So any news on the cube?" Asked Melissa

''No, so far we are leaving everything for the big day.'' Said Rohan.

''You also wants to be there to see in front row?" Asked David.

''Yes, I see something like that be studied live in a chance in a lifetime.'' Said Melissa.

''My little angel, you are curious as I am.'' Said David hugging his daughter.

''Thanks dad'' Said Melissa.

''So touching, you better not use this to win over the finances.'' Said Rohan.

''don't worry I know how to deal with them.'' Said David.

Melisa was excited to see this moment happen. That cube was thought to be a mystery for years and now her father gets the chance to do some close examination. She wonder if she could call some friends over.

''I wonder if Izuku would like to come to see it?" Though her.

With that the scientist left the girl still do her gun training.

David was going to do some research when Rohan got a phone call out of the blue.

''Sir I need to take this. Is family.'' Said Rohan.

''Sure, take your time.'' Said David.

As Rohan was going to talk in the phone, he made sure that nobody was near to hear him.

''Sir.'' Said Rohan in the phone.

''Is everything going well?" Asked a person on the phone with a German accent.

''Yes, the cube is secure and soon we will have at our disposal.'' Said Rohan all serious.

''Good, be stealthy a bunch of pro heroes will be near you.'' Said the person.

''Hail Hydra.'' Said Rohan.

''Hail Hydra.'' Said the person.

With that Rohan returned to David all smiley and with no problems.

Yes, I decided to put Hydra also in this story. They also play an important part in the stones, well the tesseract ones and soon is more cosmic stuff which I am still working on it.

I also decided to give Melissa a big role, yes kind of a triangle romance between her, Izuku and Uraraka. Who will win in the need? Seriously, I wish she was more in the canon of the story, she is canon, but she was more for the movie. But out of all those movies exclusive characters she is the most interesting and more memorable. Let's see how this goes on.

Yes, the guy is named Rohan. I am watching Jojo part 4, and he is really interesting. I like his stand and he is very powerful. Also, I like that he is voiced by Vic Micgonga he really adds something more for the character.

Also, to the guests who says to me to delete the new stories. I say no, I am doing what I like. I am going to make stories as I want. I already some that will end and don't worry, I will update the ones you like. I don't feel the burn yet, so I am good, my stories my vision.

Well thanks, see you all later.
