Group of friends who are close because they all have the same superpower except no they don’t.
As in, they all think the other ones have the same superpower as them, but, in fact, they do not.
For example:
Time traveler who always is running into these other people who seem to know what’s going on or what will happen and is so happy he can finally share his travel stories.
Precognitive who is relieved he isn’t the only one with the gift and who is glad to get help averting future disasters.
Mind reader with a horrible memory who tries to stay on top of things by skimming surface thoughts. You want to talk about next week’s election results and how they changed the next decade? She’s with you.
Totally normal guy who thinks the others have the absolute best bit ever and loves playing along.
They save the world at least twice without a single clue shared between the four of them.
