Multiverse of Marvel

"Of course I know how dangerous is it's powers. Didn't you watch the anime I made?" John asked her.

"You think I have a lots of free time to watch all your works?" the ancient one retorted.

"You really are a monster. You figured out my tattoos with just an hour of reading. No wonder you are sorcerer supreme." John murmured under his breath.

"You want me to keep the books?" she asked speculatively.

"Yes this is my help for now. Of course don't share the core information. That will be dangerous. Such knowledge shouldn't be known to anyone." John said.

"I know. I will make sure that only sorcerer supreme will have access to it's core knowledge. Thank you John. This knowledge will help generations of mages. This is a great help" the ancient one said with all sincerity.

"It's fine. If there are people who comes to the universe which has magical powers in future I will notify." he said with a smile. Then they discussed on the new knowledge, even though she didn't have in depth knowledge she could figure out the general directio of the science involved. After an hour of discussion John felt sleepy so he excused himself and left Kamar Taj. She even asked him if he wanted to learn magic.

John didn't have so much free time for now. If he has in the future he might try to learn.

The next morning John left for LA to meet Tony. After he reached his home he went directly to the laboratory. He noticed that the laboratory has become bigger than last time and it had two separate sections. One section looked extravagant and the other looked a little gloomy. John immediately knew that this two have separate laboratories now to work on their projects.

"Hey John. You are back. Wait what are those? Tattoos? You like tattoos? You never seem like that kind of person." Tony said as he came to greet John after finishing his work.

John could see many small robot like creatures working on the table.

"You seem like you have are using the full force of the cube to your advantage." John said and from the corner he saw Bruce coming out from his laboratory with a robotic dog following him.

"Yeah thanks to you our work has become easier and faster." Bruce replied to that.

"By the way you didn't watch my new series?" John asked.

"Of course we did. Your anime is very colorful. Specially loved 'Fullmetal Alchemist Brotherhood'. I loved the whole plot. I cried so many times after watching some scenes. Specially when Colonel Hughes died and her daughter crying on his funeral." Tony said with sadness. "It must be very saddening to see such worlds in dreams but can't do anything to stop them" Tony lamented.

"It's fine. I am used to it by now. Since you have seen the series don't you know what my tattoos represent?"

They both were surprised when they heard it. They both came close to see his tattoos and then Bruce suddenly realized something and said

"You used Scar'a alchemy and alkahestry? And that tattoo in your hand? Flame alchemy? From Roy Mustang?" Bruce asked with doubts. John clapped instantly

"Yes Bruce it is exactly as you said." John said.

John made those tattoos after gaining knowledge of them from the world of Fullmetal alchemist brotherhood. It was a world where science was based on transmutation circle and the theory of equivalent exchange. John's right hand could perform decomposition which means if he wanted, whatever he touched, be it organic or inorganic, it would decompose. And the left arm could reconstruct. Any material could be reshaped to any form of the corresponding material. He could make a spear out of bricks if he wanted. Of course it would take practice. And the last tattoo on his hand was flame alchemy. With just a spark he could make fire and attack enemies with fire. Same as Roy Mustang, the flame alchemist in the anime. Since fire uses oxygen for burning and spark giving the initiation the theory of equivalent exchange stood valid.

"My god now you have the knowledge of their world. Wow. Now you can finally use powers. Can you teach me alkahestry? I would love to know more about it and see if it could cure my poisoning." Tony asked with enthusiasm.

"I am here for two reasons. One for the senate hearing tomorrow, I am sure Tony got it and secondly to share the knowledge of alchemy and alkehestry." John said.

Tony was instantly excited as that would mean another means to get stronger. As for the senate hearing, he didn't really care. He just needed to hack on their servers and bring out their dirty work. Both of them are powerful and influential people. The senate can never force them to do anything.
