Supersad is part of the Sad Boi universe, obviously, but his main superpower is making people happy. Here's how it goes: you're sad about something, like maybe you made some toast but you're out of butter, then Supersad arrives. Does he bring you butter? No, he's not rich. Instead, he tells you something sad about his own life - and in doing so, you feel better about your own sadness. He's a hero.
