Fan Casting I'm in the MCU with The Flash, Green Arrow, Batman, and Superman!

Riley Cooper was just your everyday marvel/dc fan until one day, after getting hit by a truck along with his sister, he finds himself in the beginning of Avengers Endgame with some of his favorite dc heroes and special powers of his own. Together, they will help the Avengers undo the snap and build a better future. (I don't count this as a crossover, because it focuses on my oc.) https://www.fanfiction.net/s/14173405/1/I-m-in-the-MCU-with-The-Flash-Green-Arrow-Batman-and-Superman
