Your home earth is earth-10005. (Where the X-Men movies take place) Now you were in earth-616.

You are an X-Man, you were fighting some members of the Brotherhood of Mutants when you fell through a portal.

Now you were standing in the middle of a living room where people were sitting down, and they all went silent and looked towards you, multiple of them grabbing weapons.

"Who are you?" A woman said. She stood up, she had a gun pointed at you.
