How did Steele, someone from another galaxy, know how to operate a Sky Sled on their first attempt?
Evil-Lyn tells Two-Bad and Spikor to guard Blaze. But later Spikor has been replaced by Beast-Man.
Spikor has only one hand, with the other replaced by a trident as on the toy, but in contradiction to his other appearances in the series. Also going against those appearances, here he comes across as a fierce menacing warrior.
In the scene where Skeletor announces his plan, the voices for Two-Bad and Spikor get mixed up. We hear one of Two-Bad's heads say "Yeah" then the other say "Right" whilst the character is in short with two closed mouths. Then one head says "Good idea" and the other "Skeletor", both in Spikor's voice.
In the scene where Skeletor attempts to attack Grayskull with the missile, we see absolutely nothing of The Sorceress... was she away at the time, or did she just not notice?!
Adam: Come on, Cringer, we've got to help.
Cringer: Oh no, now he's got me chasing women on Sky Sleds!
Blaze: (upon seeing Snake Mountain) It looks like something out of a horror movie! It looks like some kind of... monument to evil!
Skeletor: Small correction there, it is a monument to greatness!
He-Man: Earth... so that's where my mother came from!
Blaze: What did you say?
He-Man: Nothing... er, just talking to myself!
