* CompleteMonster: Queen Bansheera, who sees her own minions, even ''her own son'', as mere pawns.
** It's ''worse'' in [[RescueSentaiGoGoFive GoGoV]], because in that, ''all'' of her minions are actually her children.
* 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]].
* 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: Bansheera's treatment of her own followers.
* 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: Vypra, namely due to Jennifer Yen's complete lack of acting skills. Carter Grayson, too, for ''his'' portrayer's acting skills and his preference of using blasters, until he was RescuedFromTheScrappyHeap as time went on.
** 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.
