Natalie Allen was the younger sister of Barry Allen, known in Central City as the Flash. Technically, she wasn't younger than him. She was 4,986 years old. When she befriends Tony Stark as a 20-year-old boy, she meets people like her. She had never met anyone like her. Then, when Tony becomes the worlds next millionaire, he invites her to be apart of an initiative called The Avengers Initiative. Her life starts to change, when, for over 15 years after joining him and the Avengers, Thanos comes to earth, and he brings death with him.
Cassie and Alexis along with their separate friends are plopped into the threat of the mad titan Thanos, who seeks to eliminate half of life with the six infinity stones, and the two may be forced to work with their own enemies to stop the mad titan.
This story is basically Avengers Infinity War and Endgame but with the inclusion of my original characters for My Place In This World.
PSA: Might want to go read My Place In This World first to get a better understanding of the characters Cassie, Alexis and Alana and maybe a few others.
I do not own any of the characters from the MCU but I do own Cassie, Alexis, you get the point.
Enjoy the story!
