With the Abyss of Evil finally opened, the Rangers must stop Lothor's ambitions once and for all when all their past foes return for revenge.
Tropes in this episode include:
- Adaptational Wimp: This trope applies to the revived generals, even though in the original version they also suffered from Conservation of Ninjutsu, they were still tough enough opponents that the entire team had to work as a team to beat them. In this version the Red Ranger defeats them by himself, almost without trying.

- Even Evil Has Loved Ones: Subverted. Despite them being family, Lothor has no problem abandoning Cam, Marah, and Kapri on a self-destructing ship. As he says, one is a hated enemy and the other two are only his nieces by marriage.
- The Fellowship Has Ended: Blake intends to pursue a motocross career and hit the racing circuit, while Hunter gets a job as head teacher at the Thunder Ninja Academy.
