When the Sorceress shows the building of Skeletor's fortress in the past by way of the Window of Time, there is a Snake Clan member (in orange) standing on top of the tower and a Ape Clan member (in blue) on the Battlement. The Snake Clan member should not be there as only the Ape Clan is working for Skeletor.

During He-Man's fight against the Dragosaur, his sword changes from his Right hand to his left between shots and back again.

Zilora and the Snake Clan introduced with her holding her staff/ax in her left hand and raises it as she speaks. The next time we seem them, the image is flopped and she is raising it with her right hand. After that, she goes back to holding it in her left.

When Skeletor rises from his Bone Throne to receive the Wheel of Infinity from Darkspy, in the wide shot, Skeletor is considerably smaller in size than usual and is standing on the throne's seat instead of in front of it.
