Adventures of the Galaxy Rangers/YMMV

Alien Scrappy: The Kiwi kids, according to some fans.
Canon Fodder: Loads and Loads of Characters, Character Development on the main four and several Recurring Characters, Too Good to Last, a couple of plot arcs that are Left Hanging, massive amounts of Backstory that was implied in two or three lines, several Noodle Incidents, and just enough of a nascent Myth Arc to hold it together.
Cargo Ship: Wildfire seems a little bit more affectionate towards his ship's AI than normal.
Complete Monster: What The Queen of the Crown does to Zach's wife alone would probably qualify her, but then take into account that this tech is what she uses to run her entire empire.
- There was also that Desolation Shot in "Tortuna" where it's explained that millions once lived in what is now a desert until "the Queen came." We also see her brutal enslavement of Wolcab, with the residents rounded up into concentration camp conditions and forced to work on her Wave Motion Gun.
Crowning Moment of Awesome: Ariel: "Haven't you heard? War is deception, and illusion is a specialty of mine!"
Cult Classic: The fanbase is small, but it is dedicated.
Drinking Game: Here.
Ear Worm: The theme song will get stuck in your head.
Ensemble Darkhorse: As Mandell put it, he intended Zach to be the protagonist, but then "Along came Goose."
Fanon: Because the series is rather obscure, there are only a handful of fanfic writers, many of who work or have worked collaboratively. As a result, there are several elements (such as a "surname" for Niko) that keep showing up.
Friendly Fandoms: With Jonny Quest the Real Adventures due to their similar tone, tropes, and several prominent Fanfic writers.
Germans Love David Hasselhoff: Galaxy Rangers was more popular in England and Europe than its country of origin; Germany got the entire series on DVD before America did. Also see Merchandise-Driven on the main page.
Mr. Fanservice: Shane, Doc, and Zach all have fangirl-attracting qualities.
Periphery Demographic: The show was more popular among teens and young adults than the toy-buying grade school boys that the producers hoped to attract.
Ship-to-Ship Combat: May be the only fandom on Earth where it's completely Inverted. Despite a sizeable body of Fanfic, most of the fanbase goes with the "canon" or Word of God 'ships; Zach / Eliza, Goose / Niko, and Doc / Maya.
The Scrappy/The Load: At Buzzwang to some fans.
- When Chris Rowley was watching a marathon put on at a small sci-fi convention, he called out "Oh, Buzzwang, we wanted to kill him so badly." The rest of the audience said (almost in unison) "So did we!"
Too Good to Last: When a cartoon from the mid-eighties gets favorably compared to Firefly?
Villain Decay: Captain Kidd starts off as a genuine threat, but eventually becomes a comic Harmless Villain in the mold of Star Trek: The Original Series' Harry Mudd.
What Do You Mean It's for Kids?: Genocide, several varieties of Mind Rape, Nightmare Fuel, on-screen death, a Dating Catwoman (or at least shagging her) situation in "Renegade Rangers," slavery, torture...even Mandell admits the show's writing "flew over the heads of six year olds."
