[Note: Later I will make one more faithful to the movie, since I already had this story since the first trailer came out.]

It was 1960, a future filled with brilliant technology and flying cars, where the Fantastic Four were already legendary. Reed Richards, the brilliant Mr. Fantastic; Sue Storm, the enigmatic Invisible Woman; Johnny Storm, the fiery Human Torch; and Ben Grimm, the unstoppable Thing, were beloved by all of humanity, using their powers to help others and defeat villains. They lived in the Baxter Building (I think so, since it's not mentioned in the movie) with their robot butler, H.E.R.B.I.E.

After a few months as heroes, they thought they were the only ones with superpowers… until you showed up. One day, on the news, they were watching you catch some villains with incredible speed and precision, using your power of (you choose your power). They were impressed. They thought it would be a good idea to have you on the team, but there was a problem: no one knew where you lived. You only appeared when something bad happened in the city, like a sudden shadow, a lightning bolt in a storm.

Until one night, just after you defeated some criminals trying to rob a bank, they found you. Your back was turned, about to leave, when you heard a voice.

Johnny: "Hey!" he shouted. #Finallyfoundyou!

Sue: "Hi," she said with a friendly smile. "We've seen what you do. You're amazing."

Reed: "You've got talent," he added. "You'd be a great addition to the team."

Ben: "I don't like that 'Fantastic Five' thing, though," he snorted. "But it sounds better than 'Four and a Mysterious Man.'"

You didn't say anything. You just looked at them. You didn't want to be part of the team. You felt like they already worked fine as they were.

You responded with a simple nod. No. Sue took a step forward.

Sue: "Then at least stay with us. You can live in the building, train, rest... You don't have to be one of us, but you don't have to be alone."

You thought about turning him down, but his gaze was hard to ignore, and you knew he'd convince you. You agreed... reluctantly.

Now, after a few days living in the Baxter Building, you were getting used to it. They'd defeated some villains together and were returning to the building, all tired, sitting in the main hall.

Jonny: "That guy was a joke!" he laughed.

Reed: "But dangerous," he said. "His armor was emitting gravitational pulses. I must study it."

Ben: "I only saw it blown to bits," he said, crossing his arms.

Sue: "Your help was key," she said, looking at you sideways with a smile.

You didn't say anything, you just sank into the chair.
