A solid 4.8!!! This is good material, good story, original too you have developed on a ending which is not canon so you can also be sure that not many fanfic will have similar start or plot. I would love it and give you 5star if only it included some break point where the mc and rest and have a character development. Like we need to expand on how one of them was willing to betray the one person without whom they had lost all hope to fight against supes
