Tropes associated with Hunter:
- The Ace: He always comes out on top.
- Adorkable: Comes with how nice and pleasant he is in demeanor.
- Brown Eyes
- 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 litteral 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".

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 Lancer: Also sometimes The Chick, usually when Colleen takes up the role of The Lancer
- Dog Bites Man
- 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.

- 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.
- 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.
- Phrase Catcher: "Muzzle 'em!", said by whoever unleashes Muzzle to attack
