Slylock Fox
The main protagonist. Slylock is a quick-thinking detective who can unravel any mystery in a moment. He is known and respected among the locals and the police, who call him in on tougher cases.
- Cunning Like a Fox
- Detective Animal
- Expy: He's partially based off of Sherlock Holmes, as evident by his name and costume.
- Great Detective: Sly can solve most cases based on a single clue.
Max Mouse
Slylock's loyal sidekick. Max isn't as quick to find answers as Slylock, and is often searching the backgrounds with a magnifying glass in hand. He has a tendency to wander into trouble.
- Bumbling Sidekick
- Nice Mice: Max is small, cute and friendly, as opposed to the villainous Reeky Rat.
- Walking Shirtless Scene: Max never wears a shirt except for special occassions or environments that require it, otherwise going only in shorts and a hat.
- Your Size May Vary: He can range from toddler-size to a little above Slylock's waist.
Chief Mutt
The chief of police, who frequently calls upon Slylock and Max for assistance.
Miss Fox
Tiffany Fox is schoolteacher and personal friend of Slylock. She occasionally calls him into her classroom as a guest speaker, and double dates with him, Max and Melody.
- Distaff Counterpart: To Slylock.
- Implied Love Interest: There's no solid evidence, but she and Slylock sure seem close.
Count Weirdly
Slylock's archnemesis is a green-skinned mad scientist, whose evil schemes are outright surreal. In addition to being a mechanical genius, he's often surrounded by bizarre monsters of his creation.
- Amazing Technicolor Population: He has green skin. In one puzzle, he claims it's because he genetically modified himself to produce chlorophyll, which eliminates his need to eat, although it's implied he's lying.
- Cut Lex Luthor a Check: He invented time travel and has never once thought to make money outside of crime. According to a Facebook post (which seems to no longer be available), it's because he's already wealthy and doesn't need the money.
- Evil Genius: The strips take place in a modern 21st century setting, but his inventions (which he obviously uses for nefarious purposes) are far beyond what exists now.
- For the Evulz
- Go-Karting with Bowser: He and Slylock aren't always at odds, since some strips have shown him, Slylock, and Max all taking a trip to the past together in his time machine.
- Poke the Poodle: Among his lesser schemes is hypnotizing cowboys into dancing for him.
- Mad Scientist
Cassandra Cat
An attractive but greedy feline. Cassandra is a would-be jewel thief whose sneaky tactics and convincing alibis never make it past Slylock and Max.
- Bitch in Sheep's Clothing
- Cats Are Mean
- Classy Cat-Burglar: Literalizes the metaphor.
- Faking and Entering: She's faked a burglary at least once in order to file a fake insurance claim.
- Femme Fatale
Slick Smitty
A human thief and con man, who tries to weasel his way out of everything with a smug grin on his face.
- Con Man: Occasionally.
- Smug Smiler: Usually spotted with a toothy smirk and half-closed eyes.
- Token Human
Shady Shrew
A grifter and petty thief whose schemes Slylock unravels on a regular basis.
- Alliterative Name
- Con Man
- Perpetual Poverty: From what we've seen of his home, crime really hasn't paid for him at all.
Wanda Witch
A human witch who tends to target Max in her schemes.
Harry Ape
A big gorilla that has a habit of robbing banks. His short, white-haired mama ape often offers false alibis for her felonious offspring.
