Mitch Rapp the CIA's top Assassin takes a mission to Central City to see what all of the news that is spreading around about people special abilities. Kennedy is assigning him to go their and see what is going on in Central City and fix the problem. The Flash and Arrow are trying to catch Rainbow Raider before he hurts more people in Central City. The Flash is going to take place before this but this will happen in this fanfic. **This will be a long Fanfiction where it is pretty much The Flash but instead of that Mitch Rapp is joining their team and helps them trying to capture meta humans mainly because that is his mission. **I do not own The Flash Arrow or any of the CW DC Comic shows plots and characters, or American Assassin Characters.
