And these are some Concepts of Locations and some ideas of scenes of the Audio plays:
A Character who is friends with Skeletor, but not an official character of Mattel. Name "Egam" (Mage, backwards)
The Ghost of Grayskull, which later will be the sorceress. The infos the writer got in the days were almost none. The ghost was described as red smoke with a skull and two crossed spears.
The Deathgate. Location: Desert of Time. Function: Leads you to the past
I named it "Manny goes to war". This depicts a scene in which Man-E-Faces grabs a Rocketlauncher and goes against a gigantic dragon in that episode. He is pulling a box of ammo for reloading. Around him guards are alerted and go into battle.
This isn't He-Man, it is Faker, the evil Robot imposter made by Skeletor. This scene is right before Tri-Klops tells him that he could rescue Teela from a Pantherdragon to have it easier to get into the castle. The real He-Man is trapped in the winds of time by Skeletor.
Funny little image, but i won't spoil it. Mer-Man won over He-man and Man-at-Arms is next.
