Hexuba, meanwhile, is Delphine, the White Alien Ranger, though she's using her Jara voice.
Robert Axelrod who did both Lord Zedd and Finster returns to voice a Monster of the Day in "The Lights of Orion" using his Lord Zedd voice
Old Shame: Danny Slavin, who essentially took the role of Leo to pay for law school and pretty much retired from acting afterwards. Nasty behind the scenes crap that went on while filming the Lost Galaxy/Lightspeed Rescue team-up the following season (essentially, the producers tried to screw over Amy Miller, the actress who played Trakeena, as far as refusing to pay her the salary they had previously agreed to; Slavin literally walked off the set alongside Miller in protest of this, forcing the producers to have to hire a body double for the remainder of his scenes and pretty much avoid showing his face during the team-up episode) only widened the gap. He also initially refused to appear in "Forever Red", only agreeing to film several scenes as a personal favor to one of the producers after filming wrapped, scenes that were ultimately added to the final cut of the episode, and has distanced himself from the character ever since, turning down numerous invitations to appear at Morphicon, the annual Power Rangers fan convention. Which makes him accepting his Megaforce cameo invitation all that more bizarre.
Prop Recycling: The suits that the soldiers wear in Lost Galaxy were carried over from the movie Starship Troopers. Which makes sense, like in Starship Troopers, the space soldiers in Lost Galaxy have to fight space insects.
Romance on the Set: Amy Miller (Trakeena) and Reggie Rolle (Damon) fell in love and then got married after the season's conclusion.
The cast was also promised a reunion movie, they never got it. Also in the team-up with Lightspeed Rescue most of the plot centers around a little girl than the actual Rangers. This lead to Danny Slavin and Amy Miller storming off the set, refusing to come back to the franchise (except for a single appearance in Forever Red, and the upcoming Megaforce cameo noted above, Slavin has refused to have anything to do with the franchise, even refusing to attend conventions).
They STARTED with having to turn a nature-themed Sentai into a space themed one, due to the success of Power Rangers in Space.
Then, early in the season, the Lights of Orion arc began, and it's near incomprehensible, because episodes were still being filmed in the week before their airdate.
When that finished, they began an arc involving the Galaxy Book, which would tie in with the two carrier Zords (which actually DID resemble the space theme to an extent, but they were rarely used in the source material so there wasn't a lot to work with), but then Valerie Vernon developed leukemia. Her character, Kendrix, was heavily involved in the plans for the Galaxy Book, which meant that arc had to rapidly be rewritten.
The original plan was for Patricia Ja Lee, the Pink Ranger from In Space, would take over. They filmed the hand off and an episode with her joining the team (which was an American-footage exclusive episode, referred to occasionally as 'Air Force Oneon the Megaship'), but then, due to pay issues, Patricia Ja Lee walked off the set. She was quickly swapped in with Karone, requiring ANOTHER two American-exclusive footage heavy episodes.
Still TRYING to do something resembling their originally planned arc, they send Terra Venture to the Lost Galaxy (the one in the title they supposedly were supposed to be heading towards). It turns out as essentially a Filler Arc, likely incorporating as much Sentai footage in order to save money for the finale.
Then, the series is pulled before the finale airs, later put out as a 'special presentation' with little promotion.
What Could Have Been: See above, and while several great plots arose from putting in Karone originally Cassie was to replace her, there's a lot of What Could Have Been if Valerie Vernon (Kendrix) didn't get sick or if Patricia Ja Lee (Cassie) had taken the part.
Actually, there was a lot of What Could Have Been even besides all that. Due to some Executive Meddling, there were a lot of last minute script changes, such as the Lights of Orion being on a cave on some forest planet, rather than on Terra Venture (which would've made a lot more sense.)
The cast was originally going to reunite for a full length Lost Galaxy movie. Instead, they got a mediocre 2-parter with the Lightspeed Rescue team.
