The Dragon Dagger now has a slightly different tone in tune to that of the original as Saban still owns the rights to the original.
The Green Ranger's costume and props differ from those of the Saban era, as a new costume had to be made for this episode. The helmet now features a silver trim along the dragon nose, the Dragon Shield is now made of a foam material like on Zyuranger (finally doing away with the much maligned cloth replacement used for MMPR) but has a diamond back unlike the Sentai original, the holster is white and on the wrong hip and the Dragon Dagger is now more Sentai accurate. These changes appear in a new picture of the Green Ranger used in the second volume of the first season of Mighty Morphin' Power Rangers on DVD and complete series DVD set. This costume would be reused for the Green Ranger's appearance in The Legendary Battle in Megaforce.
Tellingly, when the other rangers discuss Tommy's dream at the end of the episode, Ethan exclaims, "It's like all the Power Rangers universes lined up!" Whilst the ongoing appearances of Tommy and the video diary in Legacy of Power suggests that the entire PR continuity thus far has occurred in the same universe, some fans have suggested a multiverse theory to explain certain continuity problems between series over the years.
In the scene where Cassidy and Devin tell Mr. Cormier that the Power Rangers didn't show up, there are photos behind Mr. Cormier's desk have other rangers besides the Dino Thunder Rangers. More interestingly, a Pink Ranger appeared in one of the photos. It's not clear what team they are originally from.
