Heathcliff started out as a comic strip series before leaping to the TV screen. He is proclaimed the terror of the neighborhood, and no man, child, milkman, or dog (except for sometimes Spike), would dare cross him.
Tropes associated with Heathcliff:
Tropes associated with Sonja:
A musclebound bulldog owned by the local bully, and Heathcliff's favorite target. Thanks to being beaten up so often, he's actually terrified of Heathcliff, but tries to put up a tough front to support his image.
Tropes associated with Spike:
The Catillac Cats
The leader of the junkyard gang, The Catillac Cats (originally "The Cadillac Cats". The spelling was changed to avoid copyright issues with the Cadillac car company). Although he's short, he's just as tough as any other big cat, much like Heathcliff. He often plans schemes to get his hands on food or money. He is rarely successful however. Most of his schemes are just ways to please his girlfriend Cleo.
Tropes associated with Riff Raff:
Riff Raff's classy girlfriend, who lives in a music store.
Tropes associated with Cleo:
The defacto leader of the íThree Amigos! (at least, in his own mind), Hector thinks he's smarter, stronger and braver than he really is. His particular brand of Zany Schemes usually revolve around his own personal gain — and naturally backfire spectacularly.
Tropes associated with Hector:
The strongest, gentlest and dimmest of the Catillac Cats, Mungo tends to go along with whatever his friends are doing.
Tropes associated with Mungo:
A laidback inventor and amateur poet who usually tries to speak in rhymes. No matter how forced it gets at times.
Tropes associated with Wordsworth:
A junkyard dog who'd like nothing more than to drive those darn cats away once and for all! However, circumstances sometimes force him to team up with them in order to defend their home.
Tropes associated with Leroy:
Another pet at the music store where Cleo lives. Wasn't very fond of Riff Raff and the others.
Tropes associated with Bush:
