Tropes associated with Hunter:
- The Ace: He always comes out on top.
- Adorkable: Comes with how nice and pleasant he is in demeanor.
- Catch Phrase: "Yet another unexpected twist, bummer!"
- "I would not have predicted this!"
- "[X], cool."
- Cloud Cuckoolander: He's not exactly all there.
- The Leader: He is the team's leader.
- Nice Guy: Bordering on All-Loving Hero. He doesn't really bear hostility to anyone.
- Oblivious to Love: Hunter is pretty oblivious to Colleen's obvious attraction to him in-series. It got to the point where he thought her offer of a romantic walk on the beach meant she wanted to walk him in "A Day in the Life". That said, the opening credits Ship Tease them and in the aforementioned "walk" episode, he gave a bit of a knowing smile when Blitz blabbed about Colleen's jealousy.
- Super Speed: To the point he actually leaves a trail of fire behind him.
- Swiss-Army Superpower: While speed is his most obvious superpower, he's also super-playful, super-loyal, super-friendly, super-forgiving, super-generous and super-lucky. Not to mention his super-swimming, super-sniffing, super-tracking, and super-retrieving.

Tropes associated with Colleen:
- Action Girl: She does a lot of fighting.
- Alpha Bitch: A literal one, to Blitz, anyway. The guy may be a jerk, but roundhouse-kicking your coworker in the teeth whenever he does or says something that annoys you can't be good for the group's dynamics.
- Calling Your Attacks
- Catch Phrase: (generally in a sarcastic tone) "There's your comedy."
- Deadpan Snarker: She's a bit more cynical than the others and tends to make remarks about her teammates' shortcomings and quirks.
- Double Standard: Abuse, Female on Male: Whenever she kicks Blitz' ass, it's always treated as comical and a well-deserved comeuppance for... Whatever he just did to incite her ire.
- Fourth-Wall Observer: Complete with Aside Glances, her aforementioned catchphrase, and her tendency to lampshade
- Green-Eyed Monster: Albeit more of a slight Tearjerker example as Colleen becomes jealous when she believes Hunter has a girlfriend back where he's from (complete with her sadly leaving with a "Goodbye, 'Unty"). Much to her relief, it turns out he was actually just visiting his mother.
- Kick Chick: "HAI-YA!"
- The Lancer: Or The Chick depending on the case.
- The Nicknamer: Towards Blitz. As a way to insult him, she always pretends to not recognize him and give him ridiculous names that she knows he hates.
- Our Werewolves Are Different: It turns out that she is the actual werewolf in "A Hair of the Dog That Bit You" from being exposed to werewolf drool, not Exile from a werewolf scratch. Although she's returned to normal .
- Punny Name: Her name is a play on "collie".
- Wolf in Sheep's Clothing: Taken literally when she became a villainous werewolf in "A Hair of the Dog That Bit You."

Tropes associated with Blitz:
- Abhorrent Admirer: Towards Colleen, to which she usually responds with violence
- Accidental Misnaming: Colleen's favorite way of getting back at Blitz, aside from kicking his ass, is to completely screw up his name. In the final episode, she says his actual name, but returns to the usual routine when he starts being a jerk again.
- The Ahnold: He's physically fit and speaks in an Austrian accent.
- Butt Biter: Oh so much. He's kind of obsessed with biting people on their backsides, which weirds out Exile.
- Butt-Monkey: So, so much. Often courtesy of Colleen.
- Dirty Coward: Expect him to whine like a baby and offer to surrender whenever the enemy threatens him.
- It's All About Me: Has a pretty high opinion of himself.
- Jerk with a Heart of Gold: He's pretty arrogant and self-absorbed, but he still does his part in helping the team on their missions.
- The Lancer: Also sometimes The Chick, usually when Colleen takes up the role of The Lancer
- Dog Bites Man: His preferred means of attack.
- Meaningful Name: "Blitz" is a term referring to quick attacks. And being a Doberman, Blitz has a few attack dog tendencies.
- Miles Gloriosus: Often boasts about enjoying fights, but becomes cowardly when the odds are against him.
- More Teeth than the Osmond Family: Whenever he bites someone "in the tushy"
- Screams Like a Little Girl
- Trademark Favorite Food: He's revealed to be fond of peppermint milkshakes in the show's final episode.

Tropes associated with Exile:
- Ambiguously Gay: There are a few clues to this.
- In "Hair of the Dog that Bit You," we get to see Exile's room and the decor is a little feminine. Even including a vanity.
- "Two shakes of a lamb's jiffy!" and when Hunter asked what that was, Colleen replied "Don't ask..."
- Exile's Christmas Song "Jingle Balls." He had never heard of Jingle Bells either.
- When Sport joined the Rovers, Exile's immediate reaction to welcome him was to kiss him. Then he offered to give all his comrades a big kiss. Rather than turning to give Colleen the first of those kisses, he turned to Blitz instead.
- His fainting spell after assisting Colleen in surgery.
- "Awesome McCool" Name: Exilo Mikailovich Sanhusky.
- Boisterous Bruiser: He's as fun-loving as he is strong.
- Catch Phrase: (to Blitz) "Don't be weird boy."

- Genius Bruiser: In addition to being very strong, he's also a knack with machinery.

- Large Ham
- Mother Russia Makes You Strong: Although he notes he does not miss "Papa Russia"

Tropes associated with Shag:
- The Big Guy: He's physically the largest and also very strong.
- Blinding Bangs: His eyes are covered by fur.
- Hairy Hammerspace: He often has stuff hidden in his fur.
- Lovable Coward: He's not the bravest of the group, but he still helps his friends when needed.
- Running Gag:
- Shag has a bad habit of holding and firing weapons backwards. Though on one occasion, he simply turned himself around so the backwards weapon would face the right way.
- An episode-specific running gag occurs in "A Day in the Life", where he keeps drinking out of the toilet whenever the other Road Rovers need to use the bathroom.
- The Unintelligible: He remains the only Rover who doesn't speak English upon transformation, though he does say some occasional words.
- Walking Armory

Tropes associated with Muzzle:
- Ax-Crazy: A rare heroic example, as he'll violently attack anyone he's released upon. "Reigning Cats And Dogs" reveals this is the result of Parvo's failed experiment on him during the Professor's early attempts to create the Transdogmafier.
- Big Eater: He's often shown with a full belly after he's done attacking the bad guys.
- Extreme Omnivore: Is implied to devour the bad guys he attacks.
- Expy: He was obviously inspired by Hannibal Lecter from The Silence of the Lambs.
- Gory Discretion Shot: All of Muzzle's attacks are offscreen. And if the Rovers' reactions are anything to go by, it's better they are.
- Meaningful Rename: His original name was Scout. When he's affected by Parvo's failed experiment and goes crazy, he becomes Muzzle.
- Phrase Catcher: "Muzzle 'em!", said by whoever unleashes Muzzle to attack
