- Awesome Music: The show's rendition of the Ghostbusters theme adds a rocking beat to the song. It has been released to the Internet for easy listening here.
- Complete Monster: Besides the return of the Grundel (see that page for details):
- The ectoplasmic being known only as "Piper", from "The Pied Piper of Manhattan," initially seems a savior to New York City when introduced, as his pipe has the ability to repel ghosts even the Ghostbusters are powerless against. Piper soon reveals his true colors, however: he is the one responsible for the sudden plague of ghosts, and when the Mayor attempts to pay him according to contract, Piper reveals he wants more. After his requests for a statue of himself down 5th Avenue and an office in city hall are denied, Piper uses his flute to hypnotize the children of the city and tries to force them to drown themselves, gloating the mayor will "rue the day he refused to pay the Piper." When the Ghostbusters intervene, Piper has no compunction using the kids as human shields in the ensuing fight.
- Surt, from "Slimer's Sacrifice", is a godlike ghost who seeks to bring about the apocalypse. His minion Fenris prepares his coming by turning three humans into his vanguards. When Slimer ends up in the containment unit, Surt demands to know how Slimer got in there and hints that he is going to torture the information out of him. When Surt senses Eduardo's presence, he allows him to rescue Slimer and waits for him to open the exit to the containment unit so he can follow them. When Eduardo realizes Surt's plan and destroys the remote that will open the exit, Surt activates a spell he placed on Slimer to make him cut Eduardo's oxygen tank, before releasing Slimer from his control so he can realize that he just doomed his friend and be left to watch him suffocate and die, with Surt promising to return and torture Slimer after Eduardo dies.
- Fridge Brilliance:
- Egon being the mentor of the new team makes even more sense than it initially appears since he clearly demonstrated massive Papa Wolf tendencies in the original show.
- While Garrett's claustrophobia is a fairly straight forward fear on the surface, it actually has a deeper layer to it; namely, that Garrett is afraid of being helpless. This is supported by "In Your Dreams", where the thing that really freaks Garrett out in his dream isn't that he's out of his wheelchair, it's that he can't defend himself and there's no chance of making it stop, unlike most situations when he falls out of his wheelchair where either he can retrieve it himself or there's someone to help him.
- "Funny Aneurysm" Moment:
- Of the "tasteless after the September 11th attacks" variety: The second part of the series finale, "Back in the Saddle," has one scene in which the WTC Towers are being devoured by the blob-like ghost that's invading New York City.
- In the episode "Grease," Kylie offhandedly warns the others to not spend so much time on the Internet because the government could likely see and track everything they do. She's even reading a huge book about conspiracies in the scene. It doesn't seem like much, until you remember this was a cartoon that aired in 1997, a whole ten years before the now-infamous PRISM surveillance programs were launched. (Of course, the fear of such surveillance goes back as far as FidoNet...)
- Germans Love David Hasselhoff: The show was quite popular on Continental Europe, to the level that it has a few video game adaptations. In Spain, particularly, this series is the first thing many people see whenever they think on the Ghostbusters franchise thanks to its successful TV runs in the 2000s.
- Harsher in Hindsight: The premise of having Egon as the only active member of the original Ghostbusters can seem a bit darker since Harold Ramis (Egon's original actor) was the first of the original Ghostbusters to pass on in 2014.
- Heartwarming in Hindsight:
- In the Episode 'Rage', it shows Eduardo and his home life. However there, his brother and probably his father believed Eduardo was a disgrace to the family but despite that, the situation was lightened by the sight of Eduardo's nephew, Kevin who showed his support to his heroes, the Ghostbusters. Because of that, its explainable why Eduardo continued the job and boasted about it, the job of a Ghostbuster made him a worthwhile person in front one member of his family's eyes, his nephew.
- The eventual second sequel to the original 1984 film is announced as having a similar premise (next generation team) to this show.
- Hilarious in Hindsight: In the episode "Home is Where the Horror Is", one of the children asks Roland if he is Batman. The voice actors of most of the Extreme Ghostbusters would later have roles on The Batman (Garrett's actor Jason Marsden playing Firefly, Kylie's actress Tara Strong playing Vicki Vale in the direct-to-video movie The Batman vs. Dracula, and Eduardo's actor Rino Romano playing the Dark Knight himself), with Roland's actor Alfonso Ribeiro being the only one not to have a role on the series, making the boy's question more hilarious these days.
- Narm: Having Egon keep a straight face when talking about all the problems that come with old age and mentioning that he's THIRTY-NINE.
- Rescued from the Scrappy Heap:
- Slimer has a smaller role here than in The Real Ghostbusters, and is therefore much more tolerable. Additionally, his characterization is more in line with the early days of the prior series. Rather than act like a Cousin Oliver, he behaves the way that made fans like him in the first place: A Big Eater that speaks incoherently and tries to do his best to help his friends. Most memorably, he tried to pull a Heroic Sacrifice in one episode.
- Janine, likewise, is a "best of both worlds" version of her fluctuating character design and personality from the original series. She looks like her Season 4/5 version (which was considered permanent after her Deal with the Devil), but acts like an Older and Wiser Season 1 version.
- Ugly Cute: Slimer's redesign is a considerable improvement over the original.
- Unfortunate Implications: Phelous pointing out that Kylie is given a smaller blaster rather than a proper proton pack where it's implied to be weaker in his review. However, this is balanced out by the fact that she carries the all-important trap with her (hence the need for the smaller pistol system; she doesn't have room for a normal proton pack thank to the ghost trap's circular shape).
- We're Still Relevant, Dammit!: Despite putting teenaged charactersnote front and center, the series generally avoided Totally Radical territory. Except for the title (though the title could refer to the fact that the newer Ghostbusters are more badass and face more frightening ghosts than the original ones, rather than some executive's feckless attempt that making them "cool"). The racially/sexually diverse cast was another attempt to keep the show relevant to the 90's.
- What Do You Mean, It's for Kids?: Just like its brothers-in-arms, Men in Black: The Series and Godzilla: The Series, also produced by Sony Pictures Television's Adelaide Productions, this series contained massive amounts of nightmarish imagery, to the point to make its predecessor look tame. Its mere opening is enough to send chills down the spine of people who grew with the series in The '90s, even if (or because) they are fans of the work, and it is safe to say the kind of monsters and artwork this series contained for a children show would be almost unimaginable today. Earlier episodes had characters implied to actually die (albeit offscreen), which is probably why they felt forced to establish in later episodes that trapping a ghost caused a Reset Button. That's probably why they went to syndication, as that meant not having to deal with network censors.
