When He-Man is attacking Skeletor at the end of the episode, his sheaf and sword are missing from his back.
It seems strange how Two Bad remembers Skeletor's last experience with The Cosmic Comet- not only was he not in that episode, but he was not even in the series at the time, as his action figure came out just before the series' closure. Obviously his dialogue here was originally written for Beast Man, who did appear in the original episode.
Also in the original script, Beast Man and Trap Jaw were Skeletor's assistants, but the Filmation bosses asked Robert Lamb to replace them with Two Bad, as Mattel were demanding exposure for their latest figures.
Robert Lamb was ordered by Filmation bosses to make heavy revisions to the original script of this episode, because they felt Skeletor was portrayed too evilly in it! Although he had to comply with their wishes, the episode still makes a fairly strong exploration of Skeletor's character.
