Introduced in Open Season
Martin Lawrence (first film)
Mike Epps (second film)
Matthew J Munn (third film)
Donny Lucas (Scared Silly)
- Bears Are Bad News: Generally not the case, but if he gets ticked off, he gets ticked off. When he thinks that Elliot died to protect him from Shaw, he ties the hunter up with his gun.
- Beary Friendly: Being a domesticated bear and all, he's quite harmless as far as grizzlies go.
- Beary Funny: He rides a unicycle for crackers, to start with.
- Berserk Button: Being told he weighs 1,200 pounds instead of 900.
- Beware the Nice Ones: A very friendly and harmless grizzly bear, but whatever you do, do not hurt any of his friends. Shaw learned this the hard way.
- Big Eater: He's usually the first member of the group to get hungry, but could go with just some fishy crackers through most of the first film.
- Big Guy, Little Guy: With Elliot.
- Butt-Monkey: Throughout the first film. Mainly because since he was a City Mouse he had a hard time adapting to the forest life and got beaten around by the other woodland creatures.
- City Mouse: He was a domesticated bear raised by Beth and has a hard time adapting to the forest until the end where he decides to stay with Elliot and the other animals.

Ashton Kutcher (first film)
Joel McHale (second film)
Matthew W. Taylor (third film)
Will Townsend (Scared Silly)
- Accidental Misnaming: Being called smelliot by Ian or one time when Boog was having fun at an gas station:
- Boog (with helium in his voice): hello idiot.
- Elliot: (also with helium in his voice): it's Ell-iot!.
- Badass Adorable: Being an Plucky Comic Relief who can take a level in badass whenever he needs to.
- Because You Were Nice to Me: He starts following Boog after the latter unties him from Shaw's truck and calls him "Buddy".
- Big Guy, Little Guy: The little guy to Boog's big guy.
- Bumbling Dad: In the third film with how he is capable of making himself look foolish with his misunderstandings in front of Giselle.
- Butt-Monkey: He loses his antlers, is constantly bullied around by Ian and suffers from having a lot more bad luck throughout the sequels.
- Chaotic Stupid: Due to his dimwitted, selfish and sometimes unpredictable nature, he is this at times with being problematic to Boog and his friends
- The Chew Toy: Since Open Season 1, his incidents are usually played for laughs, second next to the rabbits.
- Crouching Moron, Hidden Badass: In Open Season 1, went from being a cowardly, bumbling, dimwitted and clownish deer to become more confident in defending the forest from Shaw and the hunters when he needed to.
- The Determinator: Goes astronomic lengths to "take the Boo out of Boog" in Scared Silly. Unfortunately, he can't convince anybody of his hare-brained schemes (except the Only Sane Doe).
- The Ditz: An very dim-witted mule deer that has seems to get dumber in every adaption.
- Expy: Of Sid with how they both share being optimistic, clueless and empty-headed comic reliefs when paired with the main protagonists in a serious-minded (if sorta wacky) setting and how they both share being prone to slapstick or doing foolish behavior for the sake of comedy.
- Funny Animal: Doesn't wear any clothes, but walks upright on his hind legs most of the time.
- Genius Ditz: Has shades of this every once in a while.
- Heterosexual Life-Partners: With Boog, the two are inseparable.
- Jerk with a Heart of Gold: Starts becoming this since Open Season 2 with him being too stupid and selfish for his own good, yet can resolve things when he needs to.
- The Lancer: Is this to Boog.
- Lovable Coward: Occasionally, due to his dimwitted nature or is trying to get out of danger, this being shown more likely in Open Season 1, when he escaped the gas station he was with Boog so that he wasn't caught but was unable to rescue Boog from the sugar not allowing him to realize what's going on.
- Moose Are Idiots: More specifically a deer, but he's not at all the sharpest tool in the shed.
- Overly Long Tongue: Was shown to have this in the first movie.
- Sidekick Creature Nuisance: He's a lot smaller than the others in his herd, and is self-absorbed and has quite the knack for getting on others' nerves.
- Took a Level in Dumbass: He was never the sharpest knife in the drawer, but Scared Silly made him more dumb than in the previous films.
- Trademark Favorite Food: Woo-Hoo chocolate bars.
- Ugly Guy, Hot Wife: The former, not ugly at all.
- Arch-Enemy: Shaw; the two frequently argue with each other regarding their philosophies on animal hunting, and have apparently opposed each other for a long time.
- Cannot Tell a Joke: Her sense of humor isn't that good as she thinks.
- Chuck Cunningham Syndrome: Completely vanished from the series after the first film, barring a flashback appearance in Scared Silly.
- Friend to All Living Things: Not much is shown on-screen, but she's very good with animals, having raised Boog as a cub and regularly puts on nature shows for the town's children.
- Nice Girl: She's an utter sweetheart when it comes to Boog and children.
- Affably Evil: Is this towards others, ruthless with animals when nobody but hunters around.
- Arbitrary Skepticism: He believes animals will overthrow mankind but doesn't believe Bigfoot is real. And he doesn't believe in the werewolf until he believes he encountered one in Scared Silly.
- Ax-Crazy: He loves attacking defenceless animals without provocation: he intentionally swerves off-road to hit Elliot with his car, tries to kill Boog when he realises the latter's in his house and he's all-too-happy to attempt to kill the duo when he believes an animal uprising is happening.
- Big Bad: Of the first film and Scared Silly.
- The Bus Came Back: After being absent in the sequels, Shaw returns in Scared Silly, where he is still the Big Bad.
- Companion Cube: With his gun. He names it Lorraine.
- Evil Poacher: The Big Bad of the first film and hunts a lot.
- Humiliation Conga: Has this in the first film when defeated by Boog and his newfound friends.
- I Call Her "Vera": He named his hunting rifle Lorraine.
- Implacable Man: Give him credit, he can be pretty damn driven when he feels like it. A major action setpiece of the first film is him giving chase when Boog and Elliot try to escape him by diving into the river by driving his damn truck into the river himself and using it as a makeshift speedboat.
- Jerkass: Cruel, sociopathic, and selfish.
- Large Ham: Courtesy of Gary Sinise in the first film and Trevor Devall in the fourth film.
- Laughably Evil: His expressively evil personality in the first film, by his varied, humorous dialog/sass and his sense of humor is very comical; it can arguably be considered more funnier than Beth's sense of humor itself.
Gordon Tootoosis (1st film), Lorne Cardinal (Scared Silly)
- Reasonable Authority Figure: He's just trying to keep his town safe and while he urges Beth to get rid of Boog, it's clear that he knows it's in the best interest of everyone.
- Pint-Sized Powerhouse: He's small, but strong.
- Violent Glaswegian: Has both the faux-Scottish name and the temperament to qualify.
- What the Hell Is That Accent?: It's presumably meant to be Scottish, on account of it being Billy Connolly as the original VA, but then it sounds like it's taken a drunken tour of India.
Bob & Bobbie
Georgia Engel (first three films)
Kathleen Barr (Scared Silly)
- Huge Guy, Tiny Girl: Inverted. Bob is skinny and Bobbie is fat.
- Running Gag: Whenever Bob tries to speak, Bobbie cuts him off.
- The Voiceless: Bob has never spoken a word in the films. This is mostly due to his wife cutting him off. The only time Bob has ever made a sound is at the end of the second film during the Sudden Musical Ending.
Cody Cameron (first three films)
Will Townsend (Scared Silly)
- Amazing Technicolor Wildlife: He's a blue porcupine.
- Badass Adorable: An Ridiculously Cute Critter who can easily harm anybody from his quils.
- The Friend Nobody Likes: With Elliot finding him annoying.
- Hair Color Dissonance: Supposing his blue coloration is supposed to be a stand-in for grey or black.
- Ridiculously Cute Critter: Adorable in every way.
- Pokémon Speak: Guess the one word he likes to say. Subverted as he can say other stuff too and not just "Buddy".
- Sidekick Creature Nuisance: How Elliot sees him afterwards, mainly due to him being dangerously spiky.
- Verbal Tic: Most of the time, he calls everyone buddy in spite of that being his name.
Jane Krakowski (first two films)
Melissa Sturm (third film and Scared Silly)
- Hartman Hips: Giselle has a noticeably large butt.
- Male Gaze: Her literally heart-shaped butt is often shown throughout the film.
- Only Sane Man: Whenever Boog, Elliot, and Giselle form a trio, she is easily the least crazy one of the three and the one who has to keep the guys in check.
- Parenting the Husband: In the third film, when she leaves to visit her mother, she tells the kids to watch over their father. Given how much of a clumsy klutz Elliot is and how many bad situations he gets himself into, it's pretty justified.
- Women Are Wiser: Compared to both Elliot and Ian. Especially Elliot.
Patrick Warburton (first film)
Matthew W. Taylor (second and third films)
Brian Drummond (Scared Silly)
- Ain't Too Proud to Beg: He certainly learns this about himself when Shaw and his buddies are coming to kill every animal in the forest, and Boog and Elliot are the only ones who can help them.
- The Bully: His whole attitude towards Elliot in the first film, verbally and physically abusing him for his amusement over Elliot's perceived weakness.
- The Ditz: Macho and tough as he may be, he's also goofy and spacey.
- Dumb Muscle: Strong, proud, and not too bright.
- HeelFace Turn: He's a minor antagonist in the first film with a history of bullying Elliot (for being weak in his eyes, and because they both like Giselle). Eventually, he's forced to beg Boog and Elliot for help to save his life and his herd's lives from being hunted, when the animals all team up to confront Shaw during the climax. Afterwards, he's shown to be on better terms with Boog, Elliot and Giselle.
- Jerkass: As leader of his herd, he's frequently singled out Elliot for mockery and public humiliation, kicked him around, and finally kicked him out of the herd to fend for himself. He gets better after his HeelFace Turn.
- Jerk Jock: He picks on Elliot, and tries to hit on Giselle.
- Moose Are Idiots: He's a deer, but still an idiot. Still comes across as smarter than the other male deer shown (especially Elliot).
- Screams Like a Little Girl: To be fair, it's a very justified reaction to an incoming flood.
- Reformed Bully: Ian is thoroughly humbled after he's forced to beg Boog and Elliot for help saving his life from Shaw, and he begrudgingly renounces his bullying ways for good after the end of the first film.
- Smug Snake: He's a very cocky stag with a healthy opinion of how strong and tough he is.
- Took a Level in Kindness: A downplayed example. Ian goes from being a violent, aggressive bully to a rude but otherwise harmless stag later in the series who becomes friends with the two protagonists.
- Took a Level in Badass: They may be harmless and curious creatures that are used as objects, projectiles for games or used for wiping one's face/etc, but they will fight back with hunters, this being shown in Open Season 1.
- Butt-Monkey: Thrown around everywhere and suffer a lot of Amusing Injuries.
- The Chew Toy: Their bad luck is often played up for laughs the most.
- Living Doorstop: They're used as cannon fodder.
Introduced in Open Season 2
- The Atoner: In the third film, he seems to have given up his old ways that may or may not have driven him insane in the second film. This is apparently because he was fixed.
- Ax-Crazy: In the second film until he was fixed.
- Butt-Monkey: Although it is often karmic.
- Fantastic Racism: He holds a deep prejudice towards wild animals in the second film, until he gets fixed in the third film.
- Gender-Blender Name:His name would make you think he was a girl.
- Hair-Trigger Temper: It doesn't take a lot to anger him. However, this does not pop up as often in the third film.
- HeelFace Brainwashing: Apparently, became nicer only because he was neutered.
- HeelFace Turn: Since he was neutered in the third film.
- Jerk with a Heart of Gold: Still a good friend to Weenie despite his anger issues.
- Icy Blue Eyes: Until his HeelFace Turn is shown.
- Innocent Blue Eyes: When he reformed.
- Sanity Slippage: Where he slowly begins to lose his fur and his eyes begin to get increasingly twitchy.
- Brutal Honesty: Has this sometimes, mainly dialog-wise.
- Cloudcuckoolander's Minder: As Fifi goes through his Sanity Slippage.
- Deadpan Snarker: Can be prone to have some witticisms or a wry look and reaction, especially towards Roger.
- Early-Bird Cameo: He was mentioned in the first film.
- Sleepy Head: Him being a Basset Hound gives him this look with how Roberto's eyelids seem to lower down a lot (whether he's being sarcastic or not), he does show how he can pay attention to what Fifi is telling him in some instances. But Roberto can be pretty sleepy or at times, drowsy.
- Silent Snarker: He can talk, but doesn't snark that much and shows this through body movement instead.
- Toilet Humor: He's pretty... open about his bathroom habits.
- The Dragon: He serves as this to Fifi in the second film.
- Buffoonish Tomcat: More likely due to him easily being the only simpleminded cat throughout the franchise with him being occasionally prone to slapstick situations and moments that were Played for Laughs, or him being an occasional Extreme Doormat Sycophantic Servant in Open Season 2 when he was always loyal to Stanley and his group like the scene when Fifi and his gang encountered Boog's friends at the water park for example or having his oddball moments, Roger's still very goofy, spacey and genial all things considered.
- Cats Are Superior: Completely Averted. He goes on the more pleasant, affable and friendly if slow-witted side of cats, compared to the snarky Stanley.
- Cats Are Mean: Inverted, Subverted and again, Averted entirely because of how much of a Kindhearted Simpleton he is in general and was never shown to be mean-spirited or malicious in the slightest. As far as Stanley is concerned, he's too stupid to be mean.
- Captain Oblivious: Roger doesn't seem to pay hardly any attention to his surroundings. For example, in Open Season 2, he is first seen resting on the middle of the road for no reason while Fifi's owner calls him a dumb cat and tells him to get out of the road, where he was relaxing underneath for no reason but for relaxing, where he'd start communicating with his best friend Stanley and showed how unaware how long it was ever since they first met. Afterward, Roger listens to Fifi's tale with the other pets, and he randomly says he wants a girlfriend.
- Catchphrase: "Its been ages!", "Really?"
- Cloudcuckoolander: His oddball remarks, random thoughts, occasional spacing out, being oblivious towards his surroundings, and his moments of randomness along with his playfully crack-brained behavior while a massive goofball from Open Season 2 to 3 can easily qualify him like this kind of character.
- Crazy Enough to Work: When he was wanting to be cooperative in Open Season 3, he exhibits his oddball and weird behavior to help his friends out and succeeded at that.
- The Ditz: Possibly the dumbest character in the franchise.
- Kindhearted Simpleton: Since Open Season 2, he has shown to have no mean, malicious bone towards anyone and was usually shown to be affable, caring & cheerful if a childlike, ditzy & simple-minded feline, this was shown from how friendly he is towards others and in Open Season 3 (See Crazy Enough to Work Above); he basically begged his friends to help out another character when he thought was a friend in Open Season 3 when he heard about some news with trouble being around, he may have absurd or buffoonish ways of supporting his friends, but he's still a quirky, pleasant, and well-meaning simpleton at heart.
- Fat Idiot: Obviously Inverted, Roger is blissfully stupid, but also very thin (if not only looking like he's underweight).
- Fat and Skinny: The Skinny to Stanley's fat.
- Fun Personified: Although not very energized, but this was better shown in Open Season 3, where Roger in his own ways likes having fun while being The Ditz, even when goofing around or being a massive Cloud Cuckoolander.
- The Friend Nobody Likes: How most of the characters (except for some) see Roger in spite of being a pleasant and likable character, this was pretty much sealed in this dialog:Roger: Weenie, it's been ages!Stanley: Oh, here's my chance.Mr. Weenie: Roger! Hey, let's go find your buddy, Stanley.Stanley: No no no no, he's your friend now!
- Perpetual Smiler: He's usually seen as a happy-go-lucky, unsuspecting, and cheerful cat who's always seen in a blissfully goofy state of mind and is usually sticking his tongue out whenever feeling joyous or not.
- Maniac Tongue: Somewhat Straight, Subverted and Deconstructed, while Roger is not evil, sadistic or psycho in the slightest. However, Roger always presents or talks with his tongue sticking out to indicate how blissfully crackbrained, derpy and not all that bright he is.
- Minion with an F in Evil: In Open Season 3, Roger being the friendly goofball that he is, he's always unaware of what's going on when with the temporarily villainous group he was in, which allowed him doing whatever playful, oddball idea comes up in his head in a goofy manner that shows how he would actually help his friends by clowning around and letting Boog's group & side of the story continue on their plot to then unwittingly thwart Fifi's brief mistake when joining the circus.
- Oblivious to Hatred: Since Roger has to mean bone towards anybody, he is approachable and likes being around Stanley and thinks that he's a friendly cat to be around, so Stanley would try to stay away from him as much as possible, this is also given due to how most of every character sees him as a weirdo.
- Plucky Comic Relief: Due to his Cloud Cuckoolander tendencies and moments of being slapstick-prone, he lives this and is very enjoyable & hilarious whenever his goofy sense of humor or presence occurs.
- Silly Walk: Has this while seeming to walk like a regular cat, but this was done funnily and pretty smoothly.
- Simpleton Voice: He has one of the most hilariously stupid voices in all of Western Animation, and it fits his character perfectly.
- Butt-Monkey: Occasionally, sometimes while Roger's still spacing out.
- Cats Are Snarkers: Many moments of this when played with or when around Roger.
- Category Traitor: Played with, when it comes to Roger.Fifi: (seeing Roger throws up a poster he ate) I hate cats.
Stanley: (sighs) So do I.
- Cloudcuckoolander's Minder: Was this to Roger in Open Season 2, in their first appearance, this was averted in their second appearance in Open Season 3.
- Fat and Skinny: The Fat to Roger's Skinny.
- Jerkass to One: Due to his Cloudcuckoolander's Minder demeanor, he is this when around Roger whether when Stanley needed to pause Roger's oddball nature for another reason or not.
