Badass Decay: Triskull, in the span of just one episode no less. In his first fight against the rangers, he curbstomps all five Lightspeed Rangers + 3 Lost Galaxy Rangers. In his second fight, when fighting only Carter and Leo, Carter takes him out with a single punch from his battle booster.
Complete Monster: Queen Bansheera is the queen of the demons and by far the worst of their ilk. Bansheera desires to rule the world and recreate her castle and has no care for any of her minions, being one of the worst bosses in the entire franchise. To return to power she callously absorbs her loyal minion Vypra for failing her. She later forces her general Diabolico to open fire on his enemies without caring that her most loyal minion Loki, whose only desire has ever been to serve her, is caught in the blast and dies. When he goes against her, Diabolico has his mind forcibly erased to serve as her unwilling pawn. She also shows little regard for her own son Olympius and ordered him abandoned to his fate while laughing. She later has him forced to fight alongside a brainwashed Diabolico, and his death provokes no feeling in her whatsoever. In the finale, Bansheera attempts to open a gateway to the demon realm allowing all demon-kind to pour out and overwhelm humanity, even attempting to drag Carter Grayson down to the demon realm with her after she fails. Bansheera is one of Power Rangers's cruelest villains and does her evil for her own selfish ambitions.
Ensemble Darkhorse: Ryan. While it's per the course with The Sixth Ranger, he is special in that he is the first Ranger to not have a pre-existing Sentai counterpart. He was so popular, that he was near the finals in a Ranger popularity poll, there was a demand for a Titanium Ranger Key, and some have complained that he wasn't going to be in Super Megaforce.note Rhett Fisher, Ryan's actor, was invited at first, but was later uninvited for budget reasons.
There is also the theory that says that the Rescue Zords were built from or reverse-engineered from the wrecks of the original Rescue Zords. Supposedly, this was the writers' original plan, but nothing's ever been outright confirmed on the matter.
Fan-Preferred Couple: Carter and Dana. Some episodes suggest they are interested in each other and a flashback in "The Last Ranger" reveals the two are dating.
"Funny Aneurysm" Moment: Nearly every human-sized monster gets blown up, and Carter says "Mission Accomplished", except that Jinxer always brings them back to life and megazord-sized. Saying "Mission Accomplished" except the threat is far from over, and has actually gotten worse? Seems like President Bush's infamous 2003 moment, but Lightspeed Rescue aired in 2000.
A major villain from a previous series is revived for a crossover and teams up with a villain exclusively created for that crossover, and when they come back, they are wearing a mask. Am I talking about Trakeena in Trakeena's Revenge teaming up with Triskull, or Ryoma Sengoku in Movie War Full Throttle teaming up with Megahex?
If you've watched the source material, any episode that suggests Carter and Dana are interested in one another, since their sentai counterparts are siblingsnote unlike Power Rangers Megaforce, where something similar happened, this would have happened regardless of which rangers Carter and Dana were, since in GoGoV, the entire team was a family.
Moral Event Horizon: 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.
Narm: Just about all of Vypra's dialogue would make any viewer laugh because of the incredibly bad acting.
Narm Charm: Blowing up a city with explosive feathers is... okay, it's pretty cheesy (even for Power Rangers). But the episode does its darn best to make it pretty believable.
Never Live It Down: No matter how many badass moments Carter had, two things stick out amongst fans: using his blasters and his dull personality. For the former, this criticism was unfair in "Forever Red", where the Cogs he faced used blasters as well, and he was smart enough to use his own weapon.
Considering the Rangers function as a militia, the shoot first mentality made sense.
The situation that lead to Diabolico taking Ryan and forging him into a minion of evil is one of the most potent cases of Adult Fear in the entire series. Captain Mitchell is dangling from a cliff with his Dana in his free arm and Ryan holding on to his leg for dear life. Diabolico's spirt projects itself to him and tells him that he'd save Ryan in exchange for the boy's life becoming his. It becomes a truly Sadistic Choice when at this point, Ryan's fingers slip and he begins plummeting to his death forcing Mitchell to take Diabolico's deal at the cost of never seeing his son again until Ryan turned 20. It should be kept in mind that Dana was very young during this incident and Ryan couldn't have been older than around six years old. Captain Mitchell had to spend over a decade agonizing over the fact that he couldn't save his son.
The Curse of the Cobra, with Ryan suffering and writhing in pain every time he morphs, with it coming incredibly close to outright killing him.
The end of the episode where Diabolico dies. From Impus turning into a cocoon onward, to Queen Bansheera announcing herself to the Rangers... not helping is the legitimately good score the series has makes the cocoon descending from the sky actually unnerving. (Not helping is that on the VHS release, the cliffhanger of Impus' cocoon hovering over the city was a cliffhanger).
Queen Banshera's deformed form is not a pretty sight.
So Okay, It's Average: Of all the Power Rangers seasons, this is probably the one which gets the most indifferent reaction from the fanbase. Very few actively dislike it in the same way that they do Turbo, Operation Overdrive or Samurai, but at the same time you likely won't find a single fan who considers it to be the show's best season.
An Alas, Poor Villain example comes when Bansheera forces Diabolico to fire a weapon at the Rangers despite Loki being in the way. Not only does this not succeed in destroying the rangers, it kills Loki leaving Diabolico to mourn his fallen friend and swear vengeance against Bansheera. Despite everything he'd done up to that point it's hard to not feel at least a little bad for Diabolico at this point.
They Wasted a Perfectly Good Character: Vypra, despite her actress's performance, could have easily been the most interesting villain of the season. The past two seasons had the human looking female villain either reformed (Astronema) or just a more complex character (Trakeena). Vypra... is neither. Her most notable aspect was acting as surrogate mother/big sister to Impus, but that goes away when he becomes Olympius. They could easily made her something else, a seductress, having a thing for one of the rangers or The Starscream, instead she's just a henchwoman.
They Wasted a Perfectly Good Plot: 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, Power Rangers Wild Force and Power Rangers S.P.D. would make the "Ranger more equipped to be leader, but isn't" into character plot points.
Not to mention, thanks to 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 Combat Pragmatist red rangers.
Visual Effects of Awesome: The Aquabase which was heavily detailed and built with an acutal aquarium to simulate the underwater environment.
Also, their transformation sequence is pretty awesome in and of itself. It is probably one of the more elaborate sequences on the show to date and it shows very well.
What an Idiot!: The receptionist from the Crossover episode who told a little girl "there's no such thing as monsters". As Linkara says, she is the dumbest person in the history of the entire franchise.
WTH, Casting Agency?: Koko Kashmere from the filler episode towards the end? She was played by Ruta Lee, famous as the model and dice roller from the original NBC run of High Rollers.
