So I started out as a seven year old assassin... (Part One)

Just so ya know, when someone is speaking and it is in bold and italics like this, they are speaking Greek.

.....................................................................................................................................

Natasha Romanoff was well known to the world as the coldhearted crime fighting badass woman, a S.H.I.E.L.D agent out of the Red Room filled with torture and murder.

Annabeth Chase was one of the most famous demi-gods in history- to people who knew of that mythological domain- accompanying Percy Jackson and co., surviving, fighting, and helping to win two wars for the Greeks, as well as saving the world in the process, not that regular mortals knew that of course.

But Annabeth and Natasha were actually not very different. That would make sense, since they are the same person. Natasha's whole background story and information was not a complete lie, she had been in the red room going by the name of Natalia Romanova until Luke and Thalia saved her when she was seven, but everyone thought that she had been an assassin for much longer.

After the Second Giant war, the Gods provided all the heroes with a wish. Everyone asked for something different, but Percy Jackson, being the kind hearted person that she is, asked for the Gods to give them all a break from the mythological world until they were ready to come back or there was something world threatening. That included having their criminal records from their time being demigods be wiped so that they wouldn't be tracked down by the government.

Some of the Gods blessed the Heroes, and Percy and Annabeth got blessed by all of them, giving them the power that their children would get.

Aphrodite also gave all of the heroes of Olympus second forms. Annabeth chose a form with fiery red hair and a fierce look, elegant, but strong. And that was Natasha Romanoff. They could change back and forth between the two whenever they pleased, but whenever they wanted to change back into the previous form they would just have to think about what they wanted to look like and within the minute, their appearance will have changed.

They used the mist to make sure that no one would be suspicious of these random new people who just popped up in the world, and that was that.

Natasha/Annabeth's POV

I woke up to warm arms wrapped around my body and a warm breath slowly breathing on my neck. And then the feeling of dread hits me. Gods, I have to go to those adult-children again today. I love them, I really do, they are my team and I trust them, but they can be real idiots and somehow manage to destroy everything in New York while fighting a battle while us demigods fought two wars and nobody batted an eyelash, never mind saying that not even a single civilian got even mildly injured during it.

It's been seven years since the second giant war, and slowly, the demigods have been going back into the Greek and Roman world, doing quests and such when they are needed, but still maintaining their identities in the mortal world. I have become quite well known in the mortal world as the Natasha Romanoff or the black widow, one of 'Earth's mightiest heroes' if you will, while people such as Hazel had have her second form younger looking, because she had to go  back into the sixth grade because she had to learn more of the modern world.

Now, all of us heroes lived in a giant mansion, surrounded by a border like Camp Half Blood to keep monsters out, and most of us switch between here and camp when needed on a quest.

Back to how I am in my bed with my wife, Percy Jackson, who I got married to five years ago, and I never want to leave from the warmth of the bed and her arms, but my stupid damn alarm clock is going off persistently, and I am currently staring daggers at it.......................................... yup its still in one piece, much to my annoyance.
