Skeleton King Droid (a.k.a. TV Monster) A black and bulky looking, yet powerful robot made to personally serve Skeleton King as his herald. In Season 1, as Skeleton King could not leave the Citadel of Bone, the TV Monster did his work, carrying his essence wherever it needed to go. It has a large monitor at its center, on which Skeleton King was screened. It's defeated at the end of Season 1, and was not seen until late Season 2, where it was it blown away from the Citadel of Bone, but apparently not destroyed. It returned in early Season 3, abducted by an infected robot mind who was bent on destroying everything that ever had contact with Skeleton King. No longer able to ferry Skeleton King's essence around, the TV Monster fused itself with the remnants of the robot mind instead, becoming the Skeleton King Droid (or Skeleton Droid)..
All of its attacks become upgraded, and it became undefeatable. It can take out lasers from every part of itself, transform into a ball, and fly at incredible speeds
