Chuck Cunningham Syndrome / Web Original

  • Shiny Objects Videos: Erik, Wesley, and Guido all just disappear. Enforced, as their actors moved away for various reasons.
  • Epic Meal Time: Muscles Glasses and Tyler both disappeared after falling out with Harley.
  • In The Gamer's Alliance, players coming and going means their characters are often left hanging if they don't resolve their plots or put them on the bus before disappearing. This can lead to characters fading into the background never to be mentioned again although an effort is usually made to at least acknowledge in-universe what happened to the now missing characters, particularly if they played a major role in the plot beforehand.
  • The Massive Multi-Fandom RPG: Many players left the roleplay in mid-game; sometimes it was handwaved by having them stay in the location or die or something, but often, they just... stop appearing and none of the other characters seem to notice.
