This page is about characters that show up in multiple games, such as Kairobot. They are often obtainable later in the game. Other times they aren't obtainable characters, but can appear as side characters / simply make an appearance (these will be listed).
Sally Prin appears to be a female version of Kairobot, and is often the last, or one of the last, special characters in a game to be unlocked. Unlike Kairobot or Wairobot, her name doesn't end in "bot".
Grizzly Bearington (pun on grizzly bear) is an anthropomorphic bear that makes appearances in multiple games. He often works in construction, appearing to offer to expand your store for a large sum of money.
Mister X appears in a few games in what appears to be a wrestler's mask. Unlike other special characters who often have a very similar design across games, other than his mask Mister X rarely has the same appearance.
Recurring "characters" that are typically enemies. There appear to be 2 generations of enemies the first (Epic Astro Story, Kairobotica) and a second more diverse group (Beastie Bay, High Sea Saga). Sometimes even normal recurring characters appear as enemies / monsters.
