Tropes associated with Heathcliff:
- Big Eater
- Cassandra Truth: Heathcliff would occasionally be accused of crimes that were done by another cat or dog. Everyone in town believes he's the criminal, so Heathcliff has to clear his name.
- Cats Are Mean
- Even Bad Men Love Their Mamas
- Evil Laugh: Well, more like a weird sort of Evil Chortle. Mel Blanc definitely made it distinct.
- Jerk with a Heart of Gold
- Mel Blanc: Heathcliff was his last new character.
- Real Men Wear Pink: Is often happy to let Marcy dress him as a baby and push him around in her baby carriage.
- Wouldn't Hit a Girl: In the episode "Terrible Tammy" Heathcliff can't bring himself to sock out Tammy, a cat who's equally as troublesome as he is. His girlfriend Sonja does it for him.
Tropes associated with Sonja:
- Clingy Jealous Girl
- Hair Decorations: Wears a pink bow on the top of her head.
- Bowties Are Cool: ...and another one around her neck.
- Humanoid Female Animal: Averted in her case; she's the same height as Heathcliff and doesn't have any humanlike features that he doesn't.
- Uptown Girl
- Well, Excuse Me, Princess!
Tropes associated with Spike:
- Bullying a Dragon: Despite his fear, he still frequently attempted to intimidate or attack Heathcliff. Usually, this backfired.
- Dogs Are Dumb
The Catillac Cats
Tropes associated with Riff Raff:
- Buffoonish Tomcat
- Cats Are Mean: In his worst moments.
- Conservation of Competence: Hector, Wordsworth, and Mungo either don't know, or don't care to admit that they really do need Riff Raff as their leader. He's the only one in the group that does seem to have brains. The plot of "Hector's Takeover" is built around this.
- Jerk with a Heart of Gold
- Last-Second Word Swap: From the episode "Cleo Moves In": Riff Raff is setting his place up for Cleo and mumbles to himself: "It would be nice having her here. I wouldn't have to go chasing her down for...intelligent conversation".
- Miles Gloriosus
- Mock Millionaire: He does this to impress his mother in "Riff Raff's Mom".
- The Napoleon: Riff Raff was much shorter than the rest of his gang. Though he took it better than most Napoleons, his gang members often pissed him off.
- Nice Hat: Riff Raff isn't Riff Raff without that big baseball cap.
- Tiny Guy, Huge Girl
- Ugly Guy, Hot Girlfriend: Riff Raff is by no means unappealing, but you'd wonder why someone like Cleo would ever even notice Riff Raff. In fact, in a flashback episode showing when the two first met, Cleo doesn't seem to give him a second thought until her then-boyfriend starts beating him up for no good reason.
- Zany Scheme
Tropes associated with Cleo:
- Action Girl: She could be one, as in "Who's Got the Chocolate?".
- '80s Hair
- Furry Fandom: yet another 80s gateway into the fandom.
- Getting Crap Past the Radar: She pulled this off a lot.
- Humanoid Female Animal: She's a cat that stands upright and has blonde hair, plus the breasts (or something that looks like them) and figure of a human woman.
- Nothing Exciting Ever Happens Here: She says this in "Cat Balloon".
- She wasn't afraid to let Riff Raff know whenever she was getting bored with hanging around the city or the junkyard, which easily kicked off several of their misadventures.
- Well, Excuse Me, Princess!: She used this to try and keep Riff Raff's ego in check. Sometimes it actually worked... to a point.
Tropes associated with Hector:
- Bullying a Dragon: When in Heathcliff's neighborhood, he likes teasing and goading him despite getting his tail handed back to him several times.
- Can't Get Away with Nuthin'
- Jerk with a Heart of Gold/Jerk with a Heart of Jerk
- The Lancer
- Miles Gloriosus: While Riff Raff could sometimes get away with it, Hector was far more often proven a Dirty Coward.
- Small Name, Big Ego
- The Starscream: Particularly in "Hector's Takeover", where he tries to depose Riff Raff as leader. It doesn't go well.
- Tempting Fate: No matter how many times things blow up in his face, he continues to prove himself an unintentional master of this.
Tropes associated with Mungo:
- Beware the Nice Ones: If it sinks in that you're actually threatening him or his friends...
- The Big Guy
- Does Not Know His Own Strength
- Dumb Muscle
- Gentle Giant: A prime example. He holds no ill feelings towards his enemies or his friends when they insult him, and injures caused by him are unintentional.
- Simpleton Voice
Tropes associated with Wordsworth:
- Gadgeteer Genius
- The One Who Wears Shoes: In his case, they're roller skates.
- Rhymes on a Dime: Sometimes speaks normally; the longer his line, the higher the chances of attempting to rhyme.
- The Smart Guy
