Synopsis

--------------
"Let's leave my origins. We both have unspeakable origins. But the problem is I know of your origins. Galan of Taa." John said. Galactus' eyes squinted as John said his real name out loud. He never expected someone totally out of nowhere knew his actual name.
"Never expected an unknown guy would know my origins. So what of it? I don't think it matters where I came from." Galactus replied.
"It doesn't. You did what you had to do to survive. But the problem is you made a deal with the devil." John replied. Galactus looked at John with more stoic eyes now. He had done many things in the past and he made many bad decisions. He just wasn't sure what John was referring to so he was silent. John seeing that Galactus was silent and refused to speak said
"Black Winter is coming!!"

Disclaimer : I am not an economist so I might have done some mistakes in the economics section of the story. If you have suggestions to make it better you can leave in the comments.
Warning - The MC won't be OP from the start itself and will grow to a powerful character in due time. The starting feels a bit weird because I am totally new to writing a novel and English is my second language. I don't have an editor so the conversations and descriptions might be little stiff. I am trying to improve.
P.S. This story is based on Marvel multiverse
P.S. 2 The picture is not owned by me
