- Sledge and his crew forgot all about Badonna, who escaped with the help of Madame Odius.
- When Madame Odius approaches Sledge, his gun can be seen slightly pointing at her before he points his gun at her in the next shot.
- The light in Sledge's mouth guard did not sync up to what he was saying during the entire introduction scene.
- Masaki Onishi was incorrectly credited as the “2nd Unit Director 2nd Unit Director”.
- Badonna states that she extracted all the Ninja Super Steel from the asteroid, but plenty was seen on the asteroid when Sledge left.
- Madame Odius and the crew are aware that Galvanax was destroyed despite not being around to see it in any sort of way, and it's very unlikely that the Buzzcams were still functioning, since the entire ship shut down and malfunctioned after the meteor hit the Warrior Dome.
- Also, everyone treats her as the new leader despite not having true evidence that Galvanax is dead, and even so, nothing ever appointed her to be Galvanax's successor towards ownership of the warrior dome.
- Cosmo Royale, Madame Odius, Basher Bots, and the Kudabots are the only villains surviving from the previous season.
- This episode marks the return of Sledge, Wrench and Poisandra.
- This episode also shows a small cameo of Vivix which marks the return of the Vivix.
- This episode confirms that Power Rangers Dino Charge/Dino Super Charge takes place in another universe like Power Rangers RPM when Sledge and his crew emerge from the wormhole (Previously, stated to be a Black Hole) he was sucked into in the Dino Super Charge finale. However, it has been confirmed that the original timeline Dino Charge Earth has been destroyed from that event.
- It is unknown if Fury and Curio survived too or not.
- One of Sledge's prisoners who board the Warrior Dome with him is a human-sized Kuliner from Ressha Sentai ToQger.
- This is the first time that a monster from Kamen Rider vs. Super Sentai crossover appears in Power Rangers. In this case, it was Yokai Buruburu.
