* AwesomeMusic: Lightspeed Rescue 's theme as well as the bridge that served as the series' {{Leitmotif}}.
* CompleteMonster: [[BigBad Queen Bansheera]] is probably the [[BadBoss worst boss]] in the history of the entire franchise. The [[GodSaveUsFromTheQueen queen of the demons]], Bansheera returns to power by callously sucking the life out of one and forces Diabolico, her once loyal general, to open fire on his enemies without caring her most loyal minion Loki, whose only desire has ever been to serve her, is caught in the blast and dies. Diabolico has his mind forcibly erased to serve as her pawn. Her own son, Olympius fares little better, and Bansheera once ordered him abandoned to his fate while laughing. He is forced to fight alongside a brainwashed Diabolico, and his death provokes no feeling in her whatsoever. In addition, Bansheera attempts to open a gateway to the demon realm, allowing all demon-kind to pour out and overwhelm humanity.
* EpilepticTrees: A common theory way, WAY back was that Captain Mitchell (whose first name is William) was actually a futuristic Billy from seasons 1-4. {{Jossed}} when ''Time Force'' confirmed that it took place in 2001, and Lightspeed in 2000. Billy didn't have time to have an eighteen-year-old daughter. ([[Series/PowerRangersDinoThunder Not that the lack of time]] [[Series/PowerRangersSamurai has stopped other series...]])
** It doesn't help that Billy's fanfic surname had been "Mitchell" for years, both of which were an allusion to the film ''Dave''. Eventually Jossed when Disney's official site for Power Rangers [[AllThereInTheManual finally established Blue Ranger Billy's last name as the long-rumored "Cranston."]]
** There is also the theory that says that the Rescue Zords were built from or reverse-engineered from the wrecks of the original [[Series/PowerRangersTurbo Rescue Zords]]. Supposedly, this was the writers' original plan, but nothing's ever been outright confirmed on the matter.
* EvilIsSexy: Vypra.
* FanPreferredCouple: Carter and Dana. Some episodes suggest they are interested in each other and a flashback in "The Last Ranger" reveals the two are dating.
* HoYay: Absolutely obligatory for Carter and Ryan, being the Red and Sixth Rangers.
** Same can be said for Joel and Chad in "The Mighty Mega-Battles".
** On the LesYay side, Kelsey/Nancy (from "Riding the Edge") has long been read this way by fans.
** Kelsey also does this with Dana.
* MemeticBadass: Carter Grayson.
* MoralEventHorizon: Queen Bansheera does truly horrible things. She crosses the line when Olympius, her son, ends up stuck in the local equivalent of Hell; she opts to ''leave him there'' for being useless enough to get stuck there in the first place, and seems to take perverse pleasure in doing it, too.
* NeverLiveItDown: No matter how many badass moments Carter had, two things stick out amongst fans: using his blasters and [[DullSurprise his dull personality.]] For the former, this criticism was unfair in "[[Series/PowerRangersWildForce Forever Red]]", where the Cogs he faced used blasters as well, and he was smart enough to use his own weapon.
* TheScrappy:
** Carter Grayson. His preference for using blasters and [[DullSurprise having the personality of a wooden board]] were the major reasons why he was so hated. However, over the years he was RescuedFromTheScrappyHeap in hindsight thanks to his {{Badass}} attitude, tough demeanor and all around Awesomeness.
** Vypra, also from the same season, was not so lucky. The large reason why she was so hated was due to her portrayer's [[{{Narm}} notoriously bad acting]], even ''[[UpToEleven worse]]'' than the typical ''PowerRangers'' fare.
* TheyWastedAPerfectlyGoodPlot: Dana is the Captain's daughter, she is the most knowledgeable of Lightspeed of the 5 Rangers. She is not chosen to be leader. Never once does the show actually address this issue or Dana feeling resentment or hurt. Mind you, ''Series/PowerRangersWildForce'' and ''Series/PowerRangersSPD'' would make the "Ranger more equipped to be leader, but isn't" into character plot points.
** MisBlamed: In regards to Carter, it's not his fault that his Sentai counterpart didn't use a sword. There weren't even any swords in the arsenal or toyline! Go Red used a gun, so the Red Lightspeed Ranger uses a gun.
*** Anyone realize how stupid it is for a character to be hated for being Blaster Happy?
* VindicatedByHistory: To a degree. Keep in mind when Lightspeed came out it followed fan favorite seasons ''Series/PowerRangersInSpace'' and ''Series/PowerRangersLostGalaxy'' and was succeeded by another fan favorite season ''Series/PowerRangersTimeForce'', so it was generally regarded as one of the worst with the possible exception of ''Series/PowerRangersTurbo''. But after that would come come much more panned seasons such as ''Series/PowerRangersWildForce'', ''Series/PowerRangersOperationOverdrive'', and ''Series/PowerRangersSamurai'', and ''Lightspeed'' has fared a lot better in comparison.
** Not to mention, thanks to [[WebVideo/HistoryOfPowerRangers Linkara]]'s review both Carter and the series' image overall is improved (though this started happening BEFORE Linkara's review). He points out how Carter Grayson may be dull but was a badass firefighter ''before'' being a ranger. While many fans disliked that Carter went for his guns first, Linkara ''loved'' that aspect because it made him one of the more CombatPragmatist red rangers.
* VisualEffectsOfAwesome: The Aquabase which was heavily detailed and built with an acutal aquarium to simulate the underwater environment.
