Because being Actually super is a lot of work
The thing about having powers is that people expect you to fight for the greater good, and save the people even if the people treat you poorly because that's what a hero does... Joon, Kamal and Nova... They're NOT heroes. Just 3 hot mess people going through the motions, kinda for the money, and sometimes... SOMETIMES for the morals. They're (Semi) Super at best.
