- Book Dumb: While both are uneducated, neither is made out to be unintelligent. They certainly seem a good deal sharper than the college kids, at least.
- Blood-Splattered Innocents: Both of them are horrified when they begin witnessing the gruesome accidental deaths of the college kids throughout the woods, and neither of them play any intentional part in their deaths. They attempt to warn the sheriff when he leans up against a faulty post inside the cabin that leads to his head being impaled by nails, but it happens too fast for them to prevent it.
- Cassandra Truth: Expressed sarcastically by Tucker.Tucker: Oh hidy-ho, officer, we've had a doozy of a day. There we were minding our own business, just doing some chores around the house when kids started killing themselves all over my property.
- Chainsaw Good: Tucker accidentally scares the college kids with a chainsaw early on in the film while running away from an angry swarm of bees, and Dale uses one against Chad in their climactic battle at the sawmill.
- Comically Missing the Point: Upon viewing Tucker's new cabin for the first time, they come to the conclusion that it must have been owned by some sort of archaeologist due to wind chimes made of human bones. Among the newspaper clippings strung up on the wall concerning the Memorial Day Massacre, they only notice a coupon for chilidogs.
- Dumb Is Good: Neither one of them is much in the way of traditional book smarts, but they make up for it in just how kind-hearted and well-meaning they are.
- Face of a Thug: At a glance, they're rather shifty looking, but it only takes talking to them for a moment to realize that they're both perfectly nice guys.
- Failed a Spot Check: See Comically Missing the Point above.
- Fat and Skinny: Dale and Tucker, respectively.
- Mistaken for Gay: Their first encounter with the sheriff has it look like Dale was giving Tucker roadhead.
- Mistaken for Murderer: The entire point of the movie.
- Nice Guys: Both of them are nice guys, but Dale particularly steals the show.
- Sensitive Guy and Manly Man: Dale plays the role of the sensitive guy— he's timid, unsure of himself, and wouldn't hurt a fly. Tucker plays the role of the manly man, as he urges Dale to talk to girls and stand up for himself.

- Dogged Nice Guy: He likes Allison, but is petrified by her beauty.
- Florence Nightingale Effect: He had a crush on Allison already, but he really begins to fall for her when he nurses her back to health after she hits her head.
- Freudian Excuse Is No Excuse: He sheepishly points out that while he sympathizes with Chad's (flimsy) Freudian Excuse (His mother was attacked and raped by a hillbilly to the point of insanity and his grandmother lied saying that the same hillbilly killed his "real" father), he does point out that he and Tucker had nothing to do with it, since they were kids all those years ago.
- Gentle Giant: He doesn't even like fishing.

- Rescue Romance: Develops feelings for Allison after rescuing her from the pond, and she in return is implied to start developing some of her own. After he rescues her from Chad at the sawmill, they're dating by the end of the movie.
- Shrinking Violet
- Sinister Scythe: Wields one when talking to the college kids for the first time in an attempt to appear more casual. It just causes him to come across as more creepy.
- Took a Level in Badass: By the final act, he's more than ready to take on Chad.

- Butt-Monkey: Deals with a lot more shit than Dale has to, even getting his fingers chopped off by Chad.
- Comically Missing the Point: After being captured by Chad.Chad: I've never stood so close to pure evil before. (sniff) It kinda stinks.Tucker: That was supposed to be twenty-four hour protection...

- Fingore: Chad cuts off his fingers to use them as a warning against Dale.
- I Need a Freaking Drink: Beer is his solution to everything— he even pours it on his bee stings and finger stubs.
- Lesser Star: While both of the hillbillies get their names in the title, Tucker is distinctly secondary to Dale in both screentime and story focus.
- Only Sane Man: Compared to Dale. For example, he knows that people won't believe them that one of the college kids jumped into the wood chipper by accident and later makes a What the Hell, Hero? reaction when Dale tells the one pointing a gun at them that the safety is on.
- The Peeping Tom: Dale calls him out for watching Allison strip down before skinny dipping, prompting her to slip off a rock and hit her head, kicking off the rising action.

- Played by: Katrina Bowden
A college girl studying psychology who hits her head while skinny dipping and befriends Dale after he rescues her.

- Establishing Character Moment: After Chad calls hillbillies freaks in the college kids' first scene, Allison sticks up for them.
- Fanservice: A beautiful young blonde who bares her midriff a good portion of the movie and strips down to her underwear to go skinny dipping.
- Final Girl: Due to the fact that all the college kids who tried to kill Tucker and Dale end up dead, Allison is the only one of the girls to survive.
- Hidden Depths: Has aspirations to be a psychologist, and grew up on a farm, making her no stranger to the task of digging a hole for an outhouse.
- I Owe You My Life: Sticks around with Tucker and Dale and helps out with some home renovations after Dale saves her.
- Nice Girl: She's a kind young woman who wants to become a therapist and help people. She also fully admits she was wrong to judge Dale and Tucker by their appearance, and tries to tell her friends that the hillbillies are actually nice guys.
- Only Sane Man: Aside from a few of her friends suggesting that the hillbillies aren't psychopathic killers, Allison becomes the only sane member of the group due to the fact that she has both sides of the story.
- Rescue Romance: Dale rescues her twice—first from drowning when she's knocked unconscious into the pond, and second after Chad kidnaps her and takes her to the sawmill.
- Single Woman Seeks Good Man: She goes for the uneducated, decidedly uncouth Dale, because he's a Nice Guy who encourages her dreams, treats her like a queen, and is in general a complete sweetheart.
- Slapstick Knows No Gender: On the receiving end of no less than 3 head injuries.
- Tap on the Head: Is knocked out twice within short intervals of each other. Dale gives her a helmet as a joke gift at the end of the movie because of this.

- Played by: Jesse Moss
The college kid who designates himself as the leader of the group once they believe they're being hunted by psychopathic hillbillies.
- A Real Man Is a Killer: He's obviously thrilled at the idea of having a chance to kill (while maintaining a semblance of moral high ground), and tries to bring the others along with his way of thinking. He's rather upset when they try to do the smart thing and call the cops, robbing him of his opportunity.
- All for Nothing: Literally all he accomplishes by instigating the plot of the movie is becoming a Serial Killer and giving Dale a chance to hook up with Allison.
- Ambiguous Disorder: Not in the fact he's The Sociopath or a psychotic, but in his Lust for Allison. He comes onto her like an erotomanic, somewhat.
- An Axe to Grind: His initial weapon of choice.
- Ax-Crazy: Throws hatchets at trees for no reason at the beginning of the film, which is the first indicator that there's something off about him. By the end, he's descended into all out horror villain status.
- Based on a Great Big Lie: His murderous hatred of hillbillies is rooted in his false belief that they raped his mother and killed his father. In reality, while a hillbilly did indeed rape his mother, said hillbilly was his father.
- Big Bad: Has clearly become this by the time Allison's attempt to have him and Dale talk things over fails.
- Black and White Insanity: He will not be swayed from his goal of killing the hillbillies, insisting that they're pure evil and he's the hero.
- Blood Knight: It quickly becomes apparent that Chad derives sadistic joy from the thought of killing the hillbillies, and goes out of his way to escalate the situation into a full on Hillbilly Horrors scenario entirely because he wants to be the one to finish off Tucker and Dale himself.
- Child by Rape: The excuse for his deeply rooted hate for hillbillies is that his father was killed in the Memorial Day Massacre and his mother was raped and tortured by one of the psychopathic hillbillies. As it turns out, his father was one of the psychopathic hillbillies.
- Determinator: Nothing will stop him from killing the hillbillies. Not even the deaths of his supposed friends.
- Engineered Heroics: Implied. He acts like he's the hero of some movie, and Chloe admits that it was his idea to go camping.
- Entitled to Have You: Believes he and Allison belong together due to both being "special", and attempts to kill her for "betraying" him when she chooses to be with Dale.
- Evil Cannot Comprehend Good: As noted under Black and White Insanity, he treats Allison's peace mediation as something he has to put up with, and doesn't even bother hiding the fact that he is still dead set on killing Tucker and Dale.
- False Friend: As the house is burning, and Naomi is clinging to his ankle begging for help, he just snarls.Chad: Get off me you nasty bitch!
- Forceful Kiss: While he has Allison in I Have You Now, My Pretty, he tries to kiss her. And lick her. He doesn't take her reaction well.
- Freudian Excuse: The reason for his hillbilly-hate is because his parents were victims in the Memorial Day Massacre.
- Hate Sink: His every action works to earn the audience's ire. While the movie is a comedy, Chad is a legitimately repulsive human being. and the movie takes this fact seriously.
- He Who Fights Monsters: His obsession with taking revenge on murderous hillbillies eventually transforms him into one.
- If I Can't Have You...: Comes to despise Allison because she doesn't return his affection, and attempts to kill her at the sawmill.
- Invincible Villain: Nothing can slow this guy down. Not stabbed in the ankle, not having half his face burnt off, not his Weaksauce Weakness, or falling out of a two story window. He survives the film as In Media Res shows. Dale Lampshades:Dale: Oh Jesus H. Christ that kid is tough as nails!
- I Reject Your Reality: Upon finding out the truth about his father, Allison tries to keep him from having a Villainous Breakdown. He delivers this gem:Chad: There is no truth! EVERYTHING IS A LIE!!
- Jerkass: A prejudiced, entitled prick.
- Knight of Cerebus: Chad has virtually no comedic scenes and always comes across as scary and intimidating. When he comes onscreen, it tends to means shit's about to get serious.
- Knight Templar: Leads a pointless crusade that ends with all of his friends accidentally killing themselves and each other entirely due to his irrational belief that all hillbillies are murderous psychopaths. Even when he becomes a textbook slasher movie villain, he still claims to be the hero.
- Like Father, Like Son: Becomes a psychotic killer by the end of the film, just like his father was.
- Love Makes You Crazy: One possible excuse for his declining sanity over the course of the film.
- Loving a Shadow: His idea of Allison is that she "Thinks she's better than everyone," (Which creepily turns him on), and that they're "Cut from a different cloth." He knows nothing about her personally, not even her Hidden Depths, Hair of Gold, Heart of Gold Personality.
- Made of Iron: He can take an absurd amount of punishment. As any good slasher villain should.
- Manipulative Bastard: Takes advantage of Alison's kidnapping and uses his friends' stupidity to advance his goals of murdering Tucker and Dale by manipulating them into believing that they are evil.
- Meaningful Name: "Chad" is stereotypically associated with douchey, entitled frat-bro types. Needless to say, he upholds his name's reputation to a T.
- Not So Harmless: While he shows hints of being unhinged from the very beginning, he for the most part seems to just be an asshole Jerk Jock. As the movie goes on, however, it becomes clear that he is Evil referred to in the title.
- Politically Incorrect Villain: When it comes to hillbillies. He can't be convinced that any of them are anything other than deranged killers.
- Psycho Party Member: While the rest of the college kids come across as snobbish or dimwittish, Chad is revealed to be a straight-up psycho.
- Red Right Hand: The left side of his face is horrifically burned to Two-Faced quality. Almost as bad as the Trope Namer himself.
- The Reveal: While the audience knows from the beginning that Tucker and Dale aren't killer hillbillies, it eventually comes to pass that Chad himself is.
- Spanner in the Works: His fantasy of living out a killer hillbilly movie and survive as the hero who gets the girl would've worked if, 1) Said girl having somehow found him attractive, and 2) If the Hillbillies were actually evil.
- Start of Darkness: The movie chronicles his transformation from an ordinary (if already rather creepy and unpleasant) college student to a full-on slasher movie villain.
- This Is for Emphasis, Bitch!: Used a few times.
- Token Evil Teammate: While most of his friends are just entitled idiots, Chad is a violent monster.
- Tomato in the Mirror: He was the killer hillbilly all along.
- Tragic Bigot: Albeit not a sympathetic one. Chad's murderous hatred of all hillbillies stems from the fact that a group of them killed his father. Turns out that this isn't the case, but the origins of his birth still involve a traumatic incident involving hillbillies.
- Two-Faced: The left side of his face becomes disfigured by a burn after Tucker's cabin blows up.
- Unreliable Narrator: His story about his mother and "father" has some holes in it. Not that he realizes it.
- Villainous Breakdown: Does not take the Awful Truth very well.
- Weaksauce Weakness: Asthmatic and allergic to Chamomile.
- Wrong Genre Savvy: Chad is convinced that he's the hero of a classic homicidal hillbilly scenario, and convinces the rest of his party after progressive misunderstandings continue to escalate tensions. In reality, the entire situation is a result of Poor Communication Kills, but Chad is too dead-set on murdering the hillbillies by the end that he just doesn't care. By the end, he still insists that he's the hero even after having become a walking slasher movie villain.
- Yandere: For Allison, which is only made worse by the fact that she begins developing feelings for Dale.
- You Are What You Hate: Hates hillbillies, but is himself half-hillbilly due to being the result of his mother's rape at the hands of one of the original Memorial Day Massacre killers.
- Played by: Travis Nelson
- Boom, Headshot!: How he dies.
- Cowardly Lion: Was the first to run away in the truck. But returns with the cops. Not to mention his Took a Level in Badass.
- Took a Level in Badass: After the Sheriff dies, he grabs his gun and attempts to kill Tucker and Dale. Too bad he was Too Dumb to Live.
- Too Dumb to Live: While trying to take the safety off the gun, he points it at his head. This goes as well as you'd expect.
- Played by: Joseph Allan Sutherland
- Cruel and Unusual Death: By wood-chipper.
- Hormone-Addled Teenager: Once they arrive at their campsite, Mike immediately suggests they go skinny-dipping.
- Too Dumb to Live: While this trope applies to most of the college students, he deserve a special mention. Seriously, charging and jumping head first into the wood chipper while trying to take out Tucker. Even if he hit Tuck, he would likely fall in regardless.
- Played by: Brandon Jay McLaren
- Ambiguously Gay: Asks if having a recurring dream about sucking a dick but never actually doing it is gay. His friends say yes.
- Black Dude Dies First: Averted, mostly due to his own Genre Savvy efforts to stop it from happening by avoiding direct confrontation with the "killers", as well as the sort of dangerous self-made situations that keep accidentally killing his friends off. He still dies, because everyone except the Final Girl has to of course, but notably he's the last-but-one male college student standing, meaning he'd already outlived three or four white guys by that point.
- Cruel and Unusual Death: Killed when Chad and Chloe accidentally and painfully burn him alive. His death is what causes Tucker's cabin to explode.
- Lovable Coward: Cowers for a majority of the film until attempting a Big Damn Rescue at the climax. It ends in Tucker's cabin blowing up and his, Naomi's, and Chloe's deaths.
- Man on Fire: Chad accidentally sets him on fire, and eventually the whole cabin goes up in flames.
- My God, What Have I Done?: His face says this when he accidentally disfigured Naomi's face with a weed whacker.
- Token Minority: The only African-American guy of the group.
- Played by: Chelan Simmons
- Absolute Cleavage
- Cruel and Unusual Death: Killed when Tucker's cabin explodes, although this does mean she dies faster and less painfully compared to everyone else.
- Death by Irony: After getting a light for her cigarette in Tucker's flaming cabin, the whole place explodes. She's told earlier in the film by one of her peers that smoking is bad for her.
- Drivento Suicide: Not stated, but implied, due to her My God, What Have I Done moment after accidentally contributing to Jason's death. She made no attempts to flee the burning cabin, instead foolishly lighting her cigarette while still inside.
- Dumb Blonde: Acts entitled like the rest of her party.
- Fanservice: Can be seen distantly as topless during the skinny dipping scene and wears a revealing outfit throughout the movie.
- Pink Means Feminine
- Too Dumb to Live: Lights up a cigarette in the middle of a fire lit and gasoline soaked cabin.
- Played by: Christie Laing

- Late To The Realisation: He realises that Tucker wasn't chasing him with a chainsaw, but running 'away' from bees while trying to fend them off with the chainsaw only after he impales himself, and dies moments later.
- Only Sane Man: Suggests that the hillbillies aren't psychopaths and that the whole situation is just a misunderstanding.
- We Hardly Knew Ye: The first to die of the group.
