- Lothor's bodyguards appeared in the Japanese Power Rangers show shown in Lost & Found in Translation, which was a dubbed and edited version of Bakuryuu Sentai Abaranger.
- Monsters of Lothor's army that came out of the abyss:
- Marah and Cassidy pass by each other at the end of Part 2. They both say to their partner that the other looks similar to themselves. This is a reference to the fact they are played by the same actress.
- The idea early in Ninja Storm was that the Power Rangers teams before then were fictional, making Ninja Storm separate from the earlier continuity. Whether the idea was abandoned earlier than this episode's production, it is officially debunked with this team-up, since one of Dino Rangers was (semi-) original Power Ranger Tommy Oliver, thus connecting Ninja Storm to the rest of Power Rangers. Another instance is in "Legacy of Power" in which a clip is shown giving a broad outline of the preceding eleven seasons.
- Part 2 is the first episode Mesogog is seen engaging in a fight.
- This is also the second episode in which Hunter saves Blake from a fall, the first being "Brothers In Arms."
- The name of this episode partially follows the naming convention of Super Sentai team-ups, (newer team's name) vs. (older team's name) ie. Dino Thunder vs. Ninja Storm = Thunder Storm.
- When Blake Bradley walks into Hayley's Cyberspace, Kira Ford recognizes him. This could be a nod to the episode Legacy of Power which they saw the footage of Ninja Storm.
- Tori would later appear again to team up with the Overdrive Rangers in "Once a Ranger".
- The Ninja Rangers (along with the Dino Rangers) would then appear in "Legendary Battle".
- While Vs. movies and specials are a staple of Sentai crossovers this is actually the first (and as of this writing, only) time the current team fought the previous team before teaming up later in the episode, as aopposed to the straightforward team-ups of previous Ranger crossovers/team-ups
