Detective Grimoire's two games consist of three recurring characters as well as the various suspects you encounter and interact with on your cases.
Detective GrimoireThe Protagonist, a snarky and skeptical Detective who has a bad habit of being hatless.
- Agent Scully: He highly doubts that Boggy is the murderer and let alone even exists although he does find out at the end that Boggy infact does exist BUT was correct that the REAL boggy was NOT the murderer.
- Deadpan Snarker: Grimoire himself, to Phoenix-worthy levels. And about anyone will receive that snark once they start mentioning Grimoire's hat.
- Detectives Follow Footprints: The only footprints are at the murder scene and one other area but the footprints themselves are much more important than the trail of them. Since nobody knows what the creatures feet actually look like until much later.
- Expy: The main character looks like Gumshoe, the developers even note that they explicitly based Grimoire after him.
- Hat of Authority:
- In the first game this trope is inverted. Grimoire doesn't have a hat and everyone's quite willing to point it out, much to his annoyance.
- The second game subverts it in the very beginning of the game where he starts out with a hat...only to have it blow away as soon as they arrive at the bog.
- Nice Hat: A Running Gag is pointing out the aversion of the detective having a nice hat. He apparently has one in the sequel, before shortly losing the hat. He gets it back in the end
- Parental Substitute: Somewhat implied between the little girl and Grimoire as she is heard on the phone between her and officer James, when she interrupts which we can only assume she is with Grimoire during the phone call or is living with him possibly.
- Trenchcoat Brigade: Grimoire fits this description quite well, even refereed to in game with people knowing he is a detective due to the trench coat.
Officer JamesGrimoire's friend, his superior, and most likely his mentor. He normally leaves Grimoire be and just waits outside the entrance.
- Agent Mulder: Officer James easily accepts that the creature does exist and is the likely murderer.
- Badass Mustache: Well, he certainly likes it. Grimoire can't stand it.
- Deadpan Snarker: Can certainly be this if Grimoire won't stop bugging him about his mustache.
- Old-Fashioned Copper: James seems to fit this quite well, from his cop hat to his English accent and his very impressive mustache.
- Reasonable Authority Figure: Will willingly stay out of Grimoire's way, and is equally willing to help if needed.
- Running Gag: Much like Grimoire's hat situation, James' magnificent facial hair just can't be ignored.
Little GirlA mysterious almost omnipresent little girl who follows and assist Grimoire on his cases.
- Ascended Extra: She's more or less there to give you a map in the first game, but has a greater presence in the sequel.
- Creepy Child: The fact that she's a little girl at a murder scene adds to the creep factor. And she arguably gets creepier in the second game.
- Fluffy Tamer: The little girl seems to know Boggy a bit more personally then anyone else in the game.
- Free-Range Children: She is always unoccupied and on her own doing her own thing.
- Helpful Hallucination: Grimoire tries to write the little girl off as this when she disappears after helping you in the beginning of the first game. Key word being try.
- Invisible Parents: The little girl's parents are never shown. Grimoire often asks where they are or tells her to go home with them but she never says anything herself about them. It is very ambiguous whether she has any or not.
- It May Help You on Your Quest The little girl often gives you very helpful items you can only get from her such as the map (in both games), and the key to Remmingtons office. Her motive for this is unclear but is most likely she just wants to help. It is also unclear how she got the key in the first place.
- Just a Kid: Grimoire occasionally treats her as such but is also very aware there is more to her then meets the eye.
- Kid Sidekick: Seems to end this way as she stands over the culpritEcho and seemingly stays with him after the case is over
- Little Miss Snarker: She is often very sassy and snarky when addressing Grimoire. "Saw your hat blow through here already, you must be slow...if it wouldn't even wait for you!"
- Mysterious Stranger: She appears in both games but we literally know nothing about her. Nothing about her name or why she's so invested in Grimoire and his cases.
- O.O.C. Is Serious Business: As Grimoire is near the end of solving the case in the second entry, she drops her snarky demeanor and asks him to not arrest "Boggy", showing sincere worry for it. She's relieved when Grimoire clarifies he's not arresting the creature.
- Redhead In Green: The little girl has red hair and wears a green dress in both games.
- Snooping Little Kid: the little girl kind of falls into this trope pretty well. She seems to follow Grimoire around and aid him despite having no reason to be at the crime scene.
- Stealth Hi/Bye: The girl seems to vanish without a trace in both games.
- Troubling Unchildlike Behavior: Not only does this kid hang around murder scenes, she also somehow gathers key pieces of evidence and is completely unsupervised.
- Wise Beyond Their Years: The little girl often gives off a vibe of this. She seems to know much more then she is willing to let on and understands how unfairly Boggy is treated and empathizes with how the land is being invaded upon with the tourist attraction.
- Monster Clown: The game drops some pretty broad hints that the clown was the murderer. He wasn't.
- Bookworm: She has many book in her stall she reads to catch up on studying.
- Excuse Me While I Multitask: She will often look into her book when you talk to her as part of her talking sprite loop
- Dark Is Not Evil: The frightening-looking swamp creature appears at the end to prevent Echo from escaping.
- Fish People: Played straight with the creature and original murder suspect, dubbed "Boggy".
- Gag Nose: He has a massive hooked nose.
- Posthumous Character: Having been murdered, he falls into this trope pretty easily.
- Ms. Fanservice: Sally Spears certainly counts with her flirty demeanor, skimpy top, black legging and stretching constantly to draw attention to her tight short shorts.
- You Gotta Have Blue Hair: Her hair is green.
- Animal Wrongs Group: Says he's fighting to protect Boggy's home but seems more interested in the cartoon character.
- Dirty Coward: When he killed Remington in self-defense, he went to great lengths to try and cover it up, rather than just confess. And when he is about to be arrested, he tries to run away, only for Boggy to stop him.
- Hidden in Plain Sight: He wears the torso of the monster costume for the entirety of the game without you realizing until the end. The player assumes it is just a poncho.
- Manchild: He has shades of this. He planned to put on a Boggy costume to scare Remington away, and his drawings for the costume look rather childish. Also, although he is fighting for Boggy's rights, he admits that he mainly likes Boggy for the old cartoons it was featured in.
- Only Known by Their Nickname: His real name is Edward. "Echo" is just a nickname he picked up because he "always comes back," yet he is referred to as Echo in most conversations and his profile.
- Waving Signs Around: This is literally his character sprite.
- Astonishingly Appropriate Appearance: Her design uses a leaf motif, with her hair resembling a big red leaf and her nose being the stem. Fitting for a woman who lives in the swamp.
- I Was Quite a Looker: While she doesn't look terrible now, we see a more beautiful picture of her when she was 20.
- Renaissance Man: She's skilled at fashion design, chemistry, botany...
- Captain Ersatz: Agent Folder is a play on Fox Mulder (Fo + lder) from the X-Files. Both of them believe in the existence of something that may not exist. A swamp creature for Agent Folder and the paranormal for Fox Mulder.
- Celebrity Voice Actor: Arin Hanson from Game Grumps also played the nerdy Agent Folder.
- Insufferable Genius: He really holds his encyclopedic knowledge of the swamp and Boggy over people.
- It Belongs in a Museum: He will say this exact line if you show him a certin peice of evidence, and Grimoire responds by saying he "Isn't wearing the right hat to be saying that." referencing Indiana Jones and his iconic fedora.
- Mr. Exposition: Folder is more then happy to share the backstory and History of Boggy.
- Face of a Thug: Grimoire notes that he looks imposing, but Burle turns out to be kindhearted and gentle. And indeed, he is not the killer.
- Every Man Has His Price: He bribed Remington to get permission to film a movie in the swamp.
- Jerkass: He acts rather smug and condescending.
- Prima Donna Director: A film director who is rather egotistical, and views himself as an "artist".
- The Ghost: Although the explorer is a somewhat important part of the history behind Boggy, his image is never shown and his name is never mentioned. The only person to have actually known him is Lady Waybridge.
