Madame Odius returns to Earth to track down the Ninja Nexus Prism. Sledge, Wrench and Poisandra also return and combine their forces to bring the Ninja Steel Rangers down.
- Blatant Lies: All of Victor and Monty's claims that they escaped the Warrior Dome last season are complete lies, and yet the entire city (minus the Rangers) buy into it.
- The Bus Came Back: Sledge and his crew make a surprising return after their defeat from Dino Charge. However, it's quickly revealed that this Sledge comes from the one that got sucked into the black hole in the finale.
- I Choose to Stay: Mick decides to stick around again as the Rangers needed him more than his family.
- Nice Job Fixing It, Villain!: Had Odius decided not to bring the Ninja Super Steel with her when trying to turn the Ninja Nexus Prism evil, then maybe the Rangers could not have taken advantage of that and regain their powers. Oops.
