Accidental Innuendo: Lance Falk, writer of "Destructive Nature", learned that his script had planted an unusual interpretation in one viewer's mind.
Lance Falk: "“Somebody told me after the show was on, ‘Man, that show was so dirty! You have this big, tall building, like this phallic symbol, and then this big thing that’s going to explode on top of it and spread seed all over the city.’ When I was writing it, it never occurred to me, but now I can’t not see it like that.”
Alternate Character Interpretation: Despite her competence (compared to Manx, anyway) Callie sometimes seems to exist just to be the SWAT Kats' cheerleader and remind everyone how awesome they are. She ignores all their (admittedly mostly unintentional) screwups and constantly obstructs (or tries to obstruct) Commander Feral, who—for all his bluster—really does have the city's best interests at heart.
Angst? What Angst?: The Metallikats adjust quite well to dying and being brought back to life as robots.
Better on DVD: The Warner Archive began offering "made on demand" DVD sets in December 2010. While most of the episodes were not remastered or restored in any way, two episodes did receive a small boost: "The Giant Bacteria" had a deleted scene featuring a farmer being eaten by the titular monster reinserted, and "The Pastmaster Always Rings Twice" finally got its Episode Title Card back after it was absent from practically every rerun.
Big Lipped Alligator Moment: Chopshop. In a world populated by nothing but anthropomorphic felines, Chopshop is a... laughing hyena?note Fans are still arguing about whether Chopshop is literally a hyena or not. Though hyenas are technically closer related to cats even if they behave more like dogs. In true BLAM fashion, he shows up for about five minutes at the start of the episode "SWAT Kats Unplugged" until he's captured, and is never heard from or spoken of again in the run of the series.
Just because T-Bone called him "a laughin' hyena" doesn't make it true. It's doubtful the writers would introduce a non-cat that wasn't an alien so late in the series, and have him be a nothing villain like Chopshop.
The Firefly Effect: An extremely rare case of inversion of this trope. The effect usually takes hold in three stages: the show suffers from Executive Meddling, which results in low ratings, which results in getting Screwed by the Network. SWAT Kats—in spite of the meddling—went on to get high ratings, then got cancelled in defiance of the ratings.
Foe Yay: T-Bone and Turmoil have this going on big time.
Harsher in Hindsight: The SWAT Kats flying the Turbokat into a building to save Callie. Doesn't help that said building immediately after explodes.
Only because the villain threw explosive chemicals. A better example are the Megakat Trade Towers, which are featured prominently in "Metal Urgency" and are seen briefly in "SWAT Kats Unplugged". Both times, they're at least partially damaged—and in the latter case, they appeared to be the deliberate target of the evil helicopter pilot the SWAT Kats are chasing at the episode's start.
"A Bright and Shiny Future" had Swat Kats journeying to a future where the Metallikats conquered Megakat City. In this future, the Swat Kats died when the Turbokat was shot down and they crashed into a building.
"Back off SWAT Kats! The Enforcers can/will handle this!"
Misblamed: Ted Turner was not responsible for killing the show; the decision was made well below his level. Sadly, the blame still falls on Ted Turner, due to the misquoted segment of his interview.
Narm: One of Razor's Catchphrases—"(Name of missile), deploy!"—has been accused of this.
Also, the phrase "Radical" was used as slang a few times in the second season. Thank goodness it didn't really catch on.
Older Than They Think: While it certainly is true SWAT Kats has an awesome fanbase, some are not exactly big fans of the series' production company, Hanna-Barbera. Which sometimes takes the form of people describing things that make SWAT Kats different, which was also often found in their 60s output. Mostly because the Tremblays were big fans of the super hero and funny animal super heroes of the day. As a result SWAT Kats shares a lot of tropes with some of those older action series.
