ABC did not air this episode with the rest of the third season due to the incidence of death, spatial creepiness, and great psychedelia. However, "Sting of the Scorpion/Trick or Treachery" was aired in it's place.
This show's villian, Infinata, never appeared in the Marvel comics. He comes from another Kranz Films cartoon series, "Rocket Robin Hood". In fact, the entire plot of this episode, as well as much of the animation was lifted from the RRH story, "Dementia Five".
