Unexplained Recovery: In the finale, no explanation was given for how she was restored to life. (Admittedly, no-one had ever directly stated she had been killed, although it was pretty obvious; the actress portraying her had to leave after being diagnosed with leukaemia, and the writers felt that they were safe with such an option, given the almost universal positive response to Zordon's Heroic Sacrifice in the previous series.) There was a lot of speculation among fans, like that the Sabre had something to do with it, but nothing definite.
Continuity Nod: She still changes her hair style far more often than anyone else. Maya alternates between two hair styles (loose and a twisted half up, half down style) and Kendrix generally wears either a severe ponytail or a more relaxed one with a few locks to frame her face, unless there's a specific plot-relevant reason she isn't. Karone, who only appears in about seven episodes, wears her hair loose, in a ponytail, with one pink clip pulling it to the side, with a pink headband, like Baby Spice, braided half-up with pink stars...
Sissy Villain: The way he looks. But more so by the fact he acts like a coward when his Chessmaster plans fail.
It's hard to take him seriously running away from Villamax during the first part of the finale.
The Starscream: He was easily the successor to Darkonda, once again not after the big bad, but after her powers. In the end, his greed for those powers was his undoing, as he and Trakeena battled into the cocoon containing the ultimate power, causing Deviot's ruthlessness to become infused into Trakeena and destroying Deviot himself.
Furio | (Voice actor: Tom Wyner)
Canon Immigrant: He is from Megaranger (the previous Sentai), not Gingaman.
Noble Demon: A unique example among other Noble Demon's in Power Rangers, while he never shows human compassion like Ecliptor,Villamax, or Diabolico he is fiercely loyal to his master Scorpius, treats his subordinates extremely well, and allows his opponents a fair fight rather than taking them down at the opportunity.
Non-Indicative Name: His name is play on the words Treachery, and he's incredibly loyal and honorable. Ironically he is framed by Trakeena and dies with Scorpius thinking he's a traitor.
Character Development: Quite possibly the best developed villain in a Power Rangers series that doesn't turn good. She starts off little more than a spoiled brat, not very battle competent, and more concerned with her looks than evil. After being trained by Villamax she soons takes over as the new Big Bad following her father's death and proves to be far more competent than he ever was. After merging with Deviot she becomes a complete psychopath and issues a suicide bomb attack to destroy Terra Venture, and in a last ditch effort she finally goes into the cocoon she once rejected, to obtain her One-Winged Angel form.
One-Winged Angel: Her insectile form counts as this. In Power Rangers Lightspeed Rescue, she tries to turn back into it. Thanks to the Big Bad of that series, she gets turned into a gigantic monster that's only stopped by the combined power of the Omega Megazord and the Lights of Orion.
Took A Levelin Badass: Which is shown in the course of one episode. At first she is utterly humiliated by some thugs in a Bad-Guy Bar. But after heavy training under the guidance of Villamax, she manages to deliver a humiliating defeat to said thugs.
Villamax | (Actor: David Lodge)
Anti-Villain: He only seems to serve Trakeena because he cares for her and does not seem particularly malicious himself. The only hostile actions he took where directly against the rangers.
Even Evil Has Standards: Held all the rangers, sans Leo, hostage, in order to make Leo come with him. After Leo complied, he held his word and freed the others. A more notable example is when he shows disgust at a crazed Trakeena using all her Sting Wingers as suicide bombers at Terra Venture during the Grand Finale. He finally snapped when Trakeena ordered him to destroy fleeing shuttles filled with innocents.
Villamax: (To Trakeena} You have learned... nothing...
Noble Demon: If Deviot is Lost Galaxy's version of Darkonda, Villamax is the succesor to Ecliptor. He is honorable, looks out for the female antagonist and a badass swordsman, among many other similarities.
Redemption Equals Death: Subverted. He fought Trakeena in order to prevent her from blowing up innocent people. Since he trained Trakeena in the first place, he was probably more than able to defeat her in combat, but due to his loyalty to her, he refused to fight. Thus he did not actually redeem himself in the traditional sense
Undying Loyalty: To Trakeena. It gets him killed in the end when he refuses to fight back against her.
