This would be a hard decision, I'm not sure if we can be added to both lists so I will join this one only because I don't have enough knowledge of X-Men as I have of The Flash (although I love both in the same way), so, can I be added please? I want to join this challenge
.
BTW awesome art
Uhm I know my suggestions aren't the best but something like "Speedsters" is what I have in mind right now as an idea.
