The New Adventures of He-Man

Hydron and Flipshot are sent by Master Sebrian to Eternia to find a champion of good to help them in their fight against the Evil Mutants of Denebria led by Flogg. They have a run-in with Andros and are brought to Skeletor who tricks them into thinking that he's a good guy until He-Man shows up. He-Man and Skeletor's fight is taken to Primus where He-Man proves that he's a good guy by fighting off the Evil Mutants while Skeletor forms an alliance with the Evil Mutants

During his fight with He-Man, Slush Head destroys the Trithuseum generators on Primus that prevents its core from overheating. The crystals needed to help power the Trithuseum generators upon its rebuilding can only be found in Gorn City on Denebria. He encounters the trader Meliac who Skeletor uses in his plot to defeat He-Man.

Slush Head captures the Scientists of Primus as they are working on repairing the Trithuseum generators. Upon learning that they built the shield around Primus, Skeletor sends them to the Quagmi Swamp in Denebria. He-Man, Hydron, and Flipshot head to Denebria to rescue the Scientists and get them back to Primus to repair the Trithuseum generators before Primus' core overheats.

He-Man saves Grot's garden from an attack by Hoove and Karatti. Meeting Werban in the Oasis, Skeletor tricks him into lowering Onnor's shield of protection so that Hoove can lead the Evil Mutants to invade Onnor under the cover of a peace talk.

Following the failed attack on Onnor, Skeletor sends a hologram calling out He-Man to face him on the Cameroon Asteroid. While He-Man and Master Sebrian are sure it is a trap, He-Man goes anyway. While He-Man is facing off against Skeletor, Hoove and the Mutant Shuttle Pods attack Primus' main radar station while Crita, Lizorr, and Karatti capture Master Sebrian and Drissi.

Skeletor and Quakke find a crystal on Denebria that makes Quakke stronger. Quakke tests his new strength on He-Man, Hydron, and Flipshot during their trip to get oil for the Vasionic Resonator on Denebria and they are saved by Sagitar.
