The Buddy

If your Buddy ever asks to be in the spotlight for once, slap them upside the head and remind them who the real star of the show is.

The Main's best and closest friend. As the Main is the non-adventurous version of the Hero, the Buddy is the non-adventurous version of the Hero's Ally or Sidekick. The Buddy acts as someone for the Main to act off of and go through the day with. The two are normally around the same age and at least live in nearby houses, not necessarily always having to be housemates. The Buddy likely is a Better Friend and may have to at times steer the Main in the right direction to keep them from making an immoral decision, like play a life-threatening prank on the Saint or Nerd. As a probable Better Friend, the Buddy is typically in a better mood than the Main and tries to help cheer them up when they're down. We can tell Something Is Wrong With The Universe when it's the Buddy's turn to feel bad because, as implicitly stated before, they're rarely in a bad mood.
