The tall tree that Spikor climbs towards the end is re-used from the Skytree from "The Dragon's Gift". Even though this tree is not supposed to have human characteristics, it is possible to see the face of the Skytree on its trunk in one shot!
When Spikor enters the Evilgizer, it is supposed to make him more evil and powerful, yet he emerges just as bumbling and stupid as he was before!
He-Man: Spikor talks too much.
The plot of this episode is borrowed from an episode of Star Trek, of which J. Michael Straczynski was a big fan. It was not the first time this plot had been recycled into a He-Man episode. It had previously been done in the earlier He-Man episode "The Arena", which was named after the original Star Trek episode.
