Original sentence: As a result of this, the first episode shown is often The Cosmic Comet (code: MU001).Early promotional literature from Mattel referred to Skeletor and his followers as the "Masters of the Universe" and an early version of the opening title sequence for the 1980s incarnation also uses this description (and was accidentally used on the final cut of an episode).However curiously little effort is made to introduce the heroes.However later literature and spin-offs use the term "Masters of the Universe" for He-Man and his allies.It was written as the first episode for the cartoon and has an extended sequence at the start which carefully introduces all the villains.The episode Diamond Ray of Disappearance (code: MU004) is the nearest thing to a launch episode.The order is further confused by successive VHS and DVD releases which have often followed the production code order with little regard for the chronological sequence of the episodes.The production codes allocated appear to indicate nothing more than the formal clearance of an episode's script and often this order is directly contradicted on screen - for example the episode The Return of Orko's Uncle (code: MU023) has an earlier production code than the introduction of Orko's Favourite Uncle (code: MU027).There is a lot of confusion over the exact order of the episodes in the 1980s cartoon
Edited sentence: In successive VHS and DVD releases the episode is often placed as fourth, being the fourth script to be approved and animated by Filmation (serial-number: MU004).Not surprisingly, it was also the first episode to be animated.The first script to be approved was The Cosmic Comet (serial-number: MU001) which is often concidered to be a fairly standard episode though presented a supporting character which actually made more than just one appearance in the show.Though Diamond Ray of Disappearance is considered and was written as the pilot for the 80s cartoon, it only maintained its position as the first episode during He-man's TV career
