As she went to the arena she became serious and her body language changed to a fighting mode. She knew that the guy in front of him wasn't simple. Bruce punched at her abdomen immediately which she defended by both her hands. She initiated a kick from the other side towards his upper body which he dodged.

This small harmless and flashy moves went on for a couple of seconds. Then Bruce suddenly wrapped his hands around her neck from behind after dodging her previous punch and asked coldly in a whispering voice "Who are you?"

"I am Natasha. An agent of SHIELD. I am here to evaluate Tony." she said as she was trying to free herself. Bruce loosened his hands and she fell down.

"This guy is really not simple. I took lessons from the ninjas and he could still overpower me." she said under her breath.

She was the famous Black Widow. The last few months she went to the world of Naruto to learn the way of the ninjas. She was accompanied by other agents like Clint, Rumlow and others. Even though they couldn't replicate the way of ninjas because of no presence of chakra, they still learnt some tricks. And even got to learn how to use weapons such as kunai, shuriken and even paper bombs. These new ways fascinated her and other agents.

All the agents realized that all those training over these years would mean nothing in front of a chunin, let alone the higher jonin levels. This was the miracle of chakra and all felt extremely powerless so all worked hard to overcome their gaps.

Tony and Pepper didn't notice this small interaction. Tony just felt he was hard on her so said "Lucian, she just a lady. Please go easy on her." Tony commented. Sometimes he wondered if Bruce would have a girlfriend in the future. His cold manner kept everybody out.

"It's fine Mr. Stark. He is a good teacher. My two months of defense classes proved nothing in front of him." Natasha lied immediately.

"Well he is an expert." Tony said. "I want an assistant like her." he added.

"Thomas is enough for you." Pepper left after saying that.

Soon, the day to travel to Monaco came. John came with Bruce and Tony accompanied by Pepper, Happy, Alfred and Natasha. John was not surprised seeing her. She already knew from Bruce's memories. Even though John gave his summoned characters full autonomy but still would check their memories from time to time.

In the same way he knew that SHIELD agents went to Naruto world. He even saw Hydra agents but he didn't stop them because it was almost negligible of what they could learn from their world and they could never invade the Naruto world. The world was closed entirely and in a different plane and they could never enter their plane without permission so he didn't really care.

Natasha on the other hand, had different thoughts than John. According to Fury, he knew her from before but she was sure she had never met him before today. John supposedly knew her story from a parallel universe. Fury always felt that John wasn't as simple as he showed so told her to be on the lookout for him and try to extract more information if possible.

John smiled at her when he met her on the plane but didn't say anything. She also noticed tattoos on his arms. She felt weird but didn't ask.

They finally landed in Monaco and went for the high end hotel. They next day all went to attend the grand Prix. Pepper could sense something was wrong with Tony. On asking he always denied so she stopped poking her nose. Justin Hammer was also there and Tony didn't let go of the chance of insulting him as usual. As all were having food at the table Tony suddenly vanished by excusing himself. When they noticed that Tony was missing for few minutes, they got curious of what happened.

Suddenly Pepper saw Tony in the race track replacing the driver in television. Pepper was surprised after seeing this and got worried because racing wasn't for the fainthearted. Bruce raised his eyebrows but didn't say anything. A person who was dying tended to be self destructive.

"Bruce. You should go near the race track. Wear a mask. Tony might need help." John said. Bruce was surprised by what John said but left immediately.

"Pepper did you bring the suitcase?" John asked Pepper.

"Yes. Why John? Is something going to happen?" Pepper was more worried now by the question.

"Well something might happen. But you don't have to worry about it. Bruce is here. Miss Natasha you should call Fury. He needs to hand over the archives to Tony. It's almost time." John said while looking at Natasha.

"Well it seems like my hard owned cover is blown instantly." Natsaha said with a sweet smile. John even felt his heart racing at that moment. He had forgotten how beautiful Natasha was. Her figure alone could kill many people.

"Natasha. Aren't you Natalie? Who is Fury? Are you a spy of another company." Pepper asked, now agitated, while looking at Natasha. But John said

"It's fine. She is here to protect Tony. You need to go Pepper."
