I was thinking about how some people vanished in the series so I made a list:

  1. Gooba Gooch
  2. Gwen
  3. Thumb Buddies
  4. Oliver Pook after he went into Kevin's world they didn't even look for him.
  5. Van Del, the only villain from the train in Danger & Thunder who hasn't been seen since.
  6. Same for Alien Girl
