You find yourself exploring the city of New York where crime happens randomly, until you come across a bank robbery. You decide to walk away, until he showed up...

...Until you suddenly jump scared by what seemingly looks like Spider-Man in a red and blue suit.

You let out a surprise expression and fall to the ground speechless... A nearby woman notices this too, you recognising her from different locations that you or her have been to before, it was Mary Jane Watson, Spiderman's Love Interest, or MJ for short...

Mary Jane Watson`: "...Oh, that's another crime wave actually in a row for a week."

And after all, every everyone and every City/town needs a hero that they need to admire and inspire and look up to. If New York can have Spider-Man, Captain America, Iron Man, Hulk, Thor, Black Widow, Hawkeye, Falcon, Ant-Man, The Guardians of The Galaxy of Space, The Fantastic Four, The Silver Surfer, and many more.

...What do you do now and what is your OC's origin, personality, physical appearance, history, powers/skills/abilities, and trivia?
