A group of lovable misfits from the Goon Docks. They are all facing foreclosure on their homes due to a certain Elgin Perkins' desire to expand Astoria's Country Club. Faced with the imminent loss of their homes and friends, the Goonies embark on an adventure to find the treasure of an infamous pirate, One-Eyed Willy, in a last ditch effort to stop Perkins.
- Four-Man Band:
- Only Known by Their Nickname: All the companions are referred to by nicknames, and their real names are either rarely mentioned or not mentioned at all: Michael Walsh - Mikey; Clark Devereaux - Mouth; Richard Wang - Data; Brandon Walsh - Brand; Lawrence Cohen - Chunk; Andrea Theresa Carmichael - Andy; Stephanie Steinbrenner - Stef; Lotney Fratelli - Sloth.
- True Companions: They squabble often enough but the lengths they'd go to for each other solidifies this troupe.
Michael "Mikey" Walsh
When the opportunity comes to go on an adventure to find Willy's lost treasure and save the Goon Docks, Mikey jumps at the chance.
- Accidental Kiss: With Andy, after Brand asks him to go to see what she wants. Not that he didn't enjoy it, but who wouldn't?
- Annoying Younger Sibling: Mikey (and his friends) is this to Brand. Their mother charges Brand with keeping an eye on Mikey during the day, which he's none too thrilled about. Mikey and co. escape by tying Brand to a chair and then he has to track them down. Brand tends to think Mikey is this so much so that he actually states that he wishes had a younger sister instead of a brother. Mikey also accidentally steals Andy's First Kiss from Brand. A bit of a subversion as Mikey is the protagonist.
- Ascended Fanboy: He grows up loving his Dad's stories about the pirate One-Eyed Willy and suddenly finds himself chasing after his long lost treaure. And eventually coming face to face with him.
- Determinator: "Goonies never say 'die'!" is this combined with No One Gets Left Behind - no giving up before the end of the quest, and no abandoning your friends.
- First Kiss: Accidentally with Andy.
- The Heart: Encourages the Goonies to stick to the quest.
- Jumped at the Call: Mikey doesn't waste any time after discovery of One-Eyed Willy's map to commit to an adventure and to convince Mouth, Data, and Chunk to go along.
- Kid Hero: He's the Goonie who gets the main focus and serves as the main protagonist.
- Malaproper: Tends to mix up complicated words. He seems to have inherited this trait from his mother.
- Nerdy Inhaler: He has one that he throws away at the end of the movie, insinuating that now he's had adventures he's less nerdy. This is probably justified due to the fact that he was misusing it before, and has realized it's time to stop focusing on his weaknesses if his life is going to move forward. Treating an inhaler like a security blanket leads to over-medication, and ultimately, worse asthma.
- Post-Kiss Catatonia: Downplayed but he's certainly in a bit of daze afterwards.
- Rousing Speech: When it looks like the gang's about to give up on the adventure, he gives a pretty compelling speech about seizing the opportunity to do something great.
- Rube Goldberg Device: Mikey has one of these at his house. It's used as a gate opener.
- Saving the Orphanage: Believes wholeheartedly that they can find the treasure and save their homes.
- Throwing Off the Disability: He throws away his inhaler at the end, having apparently defeated asthma through life experience. (It can be aggravated by stress and anxiety, but that's probably a bit much.)
Clark "Mouth" Devereaux
Talkative and abrasive Mouth very much lives up to his nickname.
- Belligerent Sexual Tension: With Stef, oh so much.
- Captain Morgan Pose: An Establishing Character Moment for Mouth when he puts his foot on the living room table in an attempt to look cool, until Brand tells him to stop it.
- Chekhov's Skill: Mouth's fluency in Spanish.
- Cunning Linguist: He plays this role.
Mrs. Walsh: Now Rosalita, this is the attic. Mr. Walsh doesn't like anybody up here, ever. That's why it's always open.
- His knowledge of Spanish is strong enough for him to deliberately mistranslate instructions to the Walsh's maid for his own amusement.
Mouth: [to Rosalita in Spanish] Never go up there. It's filled with Mr. Walsh's sexual torture devices.
- Deadpan Snarker: He sarcastically mocks people so frequently that it informed his nickname.
- Extended Disarming: Once Mama Fratelli realizes he's got treasure in his mouth, she makes a point of fishing it all out. It takes nearly a minute, and she expresses shock twice over the fact that there's still somehow more in there, including a whole pearl necklace.
- Hidden Depths: Mouth in the wishing well.Stef: Wait, stop, stop! You can't do this.
Stef: Because these are somebody else's wishes. They're somebody else's dreams.
Mouth: Yeah, but you know what? This one, this one right here? This was my dream, my wish. And it didn't come true. So I'm taking it back. I'm taking them all back.
- Jerk with a Heart of Gold: Shifts between the two, especially the latter when he's around Stef.
- Meaningful Name: Unsurprisingly he doesn't know when to keep his mouth shut. No matter the situation.
- Also illustrated when Ma Fratelli has to go through an Extended Disarming scene of getting treasure he's hiding. He literally has a big mouth.
- O.O.C. Is Serious Business: Mama Fratelli knows something must be up when everyone else is shouting, but the kid so obnoxious that he gets nicknamed "Mouth" is silent. She suspects - correctly - that he put a bunch of treasure in his mouth.
- Phrase-Catcher: "Shut up Mouth!" The amount he runs off his mouth to the annoyance of others reaches Running Gag territory.
- Silly Rabbit, Idealism Is for Kids!: Stef accuses him of stealing other peoples' hopes and dreams when lifting coins from the wishing well. Mouth quickly calls her out on this by informing her that his wishes and dreams never came true and so he's taking them all back.
- Spotting the Thread: Ma Fratelli notices he's awfully quiet for a guy called Mouth. Turns out it's because he's stuffed a fortune worth of treasure into his mouth.
- With Friends Like These...: He LOVES to tease Chunk so much, to the point where Chunk tries to kill him.
Richard "Data" Wang
Amateur inventor who brings his smarts and gadgets along for the journey with his friends.
- Asian and Nerdy: Data, but it didn't make him any less of a badass when it came to facing danger.
- Asian Speekee Engrish: Data occasionally slips into this.
- Awesome, but Impractical: Most of his inventions fall under this.
- Badass Longcoat: His army green raincoat, which conceals several of his inventions.
- Bilingual Bonus: Is fluent in Cantonese.
- Bungling Inventor: Played with. Some of his inventions fail miserably or only work for a limited time. However there's also several notable occasions when they saved the day, along with his own life..
- Gadgeteer Genius: He (possibly with the help of his dad) built several gadgets that save both the life of himself and his friends multiple times during the quest.
- Dynamic Entry: Via Improvised Zip Line. Though a little more dynamic than he intended.
- Grappling-Hook Pistol: Data's actually got two versions of these. One he uses in the intro and towards the end on Ma Fratelli both times with a rather poor outcome and the more effective "Pinchers Of Peril" he has on each of his sleeves. Though the Pinchers were likely not intended for this use.
- Groin Attack: His use of slick shoes leads to some very painful moments for the Fratelli brothers. Though his later use of his "Pinchers Of Peril" is probably even worse. Not that his victims deserve any sympathy.
- Homemade Inventions: He isn't shown making any during the film, but all of his gadgets are ones he designed, several with parts obviously taken from toys and the like (the "Pinchers of Peril," for example, use most of the body of a chattering teeth toy). Based on the camera in the ending, his father may have helped.
- Saving the Orphanage: Really doesn't want to move to Detroit.
- Shared Family Quirks: At the end we witness that his father is a Bungling Inventor himself.
- The Smart Guy: He's a Gadgeteer Genius and unarguably the smartest Goonie thanks to his various inventions.
- So Proud of You: When Data's dad, an inventor like his son, tries to take a picture with a spring-loaded camera though it fails. Data tells his father that it's alright, since he cannot hug a photo. His dad responds with "You are my greatest invention."
- Token Minority: He is the only non-white character in the cast.
- Tricked-Out Shoes: "Slick shoes! Are you crazy?!"
Lawrence "Chunk" Cohen
Chunk finds himself in the rare position of telling the truth about a police car chase he witnessed but finds none of his fellow Goonies willing to believe him. A lifetime of tall tales and pranks will do that.
- Attention Whore: Implied to be one of the reasons he lies so much.
- Bad Liar: When confronted with the fact he once claimed Michael Jackson came round to his house to use the toilet. He later relented and admitted he didn't, but his sister did.
- Big Damn Hero: Along with Sloth comes to the rescue of the Goonies in the finale. Though exactly how they got down to their location so fast is anyone's guess.note
- Berserk Button: First when Mouth tells Chunk he has naked pictures of his mom taking a bath, real cheap, forcing Chunk to break the door open. Second, averted, when Chunk accidentally breaks the water cooler he was drinking from when Mouth thought of putting chocolate on the floor so he can eat through. "Okay Mouth, that's all I can stand and I can't stand no more!"
- Big Eater: To the extent that, according to him, he got kicked out of a camp for fat kids for pigging out.
- Brains and Brawn: The brains to Sloth's brawn.
- Butt-Monkey: Poor schmuck just can't catch a break until the finale.
- Cassandra Truth: All his talk about seeing a police chase and then noticing the very same ORV with bullet holes in it is largely dismissed due to his past reputation.
- Crying Wolf: Chunk bitches the most about everything that takes place, and is chewed out by every other person in the movie for it because of his history of being a Crying Wolf.
Sheriff: "Just like that last prank about all those little creatures who multiply when you throw water on them."
- Yet he turns out to be completely right about the Fratellis and what they're up to. When he attempts to phone the police about the Fratellis chasing after his friends over buried treasure the sheriff chalks it up to yet another outlandish tale.
- Fat Camp: One of the things Chunk confesses to when caught by the Fratellis was being sent to a fat camp and getting kicked out for pigging out.
- Fat Comic Relief: He has to do his "Truffle Shuffle" to be allowed into the gang's house.
- Hero of Another Story: He forms the B-Plot of the movie by getting caught by the Fratellis and forming a friendship with Sloth while the rest make their way through the crypts.
- He's Dead, Jim: "It's a STIFF!"
- Hyper-Awareness: Simply by smelling them, Chunk can tell what toppings are on a pizza, the same goes for ice cream flavors in a locked freezer.
- Informed Judaism: His family name is Cohen, and there's his 'confessions' to the Fratellis: "I stole my uncle Max's toupee and glued it on my face when I played Moses in my Hebrew school play".
- Kid-Appeal Character: The Goonie who most applies for this trope, being the Fat Comic Relief.
- The Klutz: To the point that his when his fellow Goonies need something broken they just ask him to hold it or provoke him.
- Mouthy Kid: He cannot shut up.
- My God, What Have I Done?: During Chunk's "confession" to The Fratellis he says the worst thing he ever did was mixed up a bunch of fake puke, took it to a movie theater, went to the balcony and poured it on the people below and everyone in the audience started getting sick and throwing up all over each other. He had never felt so bad in his entire life.
- Phrase-Catcher: "Shut up, Chunk."
- Survival Mantra: While running through trees in the night, he plays this straight and also inverts it.Chunk: I'm not afraid of the dark. I like the dark. I love the dark. But I hate nature. I hate nature!
- Vomit Chain Reaction: Chunk claims he accidentally started one in a movie theater as a result of a practical joke involving fake puke Gone Horribly Wrong.
- You Have to Have Jews: Despite the fact that only 0.24% (less than 1 out of 400)of Oregonians are Jewish, Lawrence "Chunk" Cohen mentions playing Moses in his Hebrew School play (using his uncle's toupee as a beard), mentions having Hannukah decorations at home, and recites a Jewish prayer in panic when confronted by Jake Fratelli.
Brandon "Brand" Walsh
Mikey's big brother, who as the eldest tries to be the most level headed of the group. Initially he's just trying to get Mikey back home safe but ends up swept up in the adventure too.
- All Guys Want Cheerleaders: Or in Brand's case a girl who happens to be a cheerleader.
- Aloof Big Brother: Downplayed but there's shades of this.
- Big Brother Instinct: He only gets involved to save his brother from himself. And throughout the film goes out of his way to protect not only Mikey but the other Goonies.
- Butt-Monkey: Failed his driving test letting all the Goonies down, ended up tied to an armchair, had his brand new tires flattened and was then forced to ride around on a pink bicycle. The final insult being thrown off a hillside in front of the girl he likes.
- Hoist by His Own Petard: Mikey and company tie Brand to an armchair with the exercise equipment he's currently using.
- Ineffectual Death Threats: When threatening to kill the Goonies for tying him to his armchair and letting the air out of his bikes tires. Both reactions are fairly typical of an older brother. Though there's no doubt he'd likely get his own back in a less lethal manner.Brand: "I'm gonna hit you so hard that when you wake up your clothes will be out of style!"
- One of the Kids: He spends the first act of the film trying to keep his little brother and his friends in line, but he eventually gets swept up in the adventure as much as the rest of them.
Andrea "Andy" Carmichael
- The Cheerleader: A subversion given she's not at all an Alpha Bitch and actually very nice.
- Chekhov's Skill: She used to take piano lessons. However she's very rusty. Which makes the skeleton organ scene all the more dramatic when she hits the wrong notes.
- Dangerously Short Skirt: Leading to quite a few Panty Shots. She was on her way to a scheduled court time at the country club when she got pulled into the adventure.
- Dude Magnet: Andy. Troy wants her. Brand wants her. And Mikey clearly does not mind her kissing him passionately.
- Heroic BSoD: Has a slight meltdown at the beginning of their journey. Though she snaps out it eventually.
- Hysterical Woman: She starts panicking and screaming in the cave.
- The Load: Eventually subverted. For a good portion of the adventure she's not particularly helpful (and even gets hysterical) but finally proves her worth when the others realise she's the only one who can read the music and play the skeleton organ.
- Ms. Fanservice: Andy, by way of She's Got Legs and Panty Shot."Don't I have a beautiful body?! Don't I have a beautiful body?!?"
- Offscreen Moment of Awesome: She informs Brand that she punched Troy in the face for being a pervert once too often, giving him a fat lip in the process. She did warn him.
- Panty Shot: In several scenes, notably where she falls off the ship's plank into the lagoon.
- Tomboy and Girly Girl: Despite her Tomboyish Nickname, she's the girly girl to Stef's tomboy.
- Walk the Plank: Ma Fratelli forces her to do this after Andy insults her. Brand saves her luckily.
Stephanie "Stef" Steinbrenner
Stef's friends with Andy and, like her, doesn't usually associate with the Goonies. But she ends up following Andy and getting pulled into the quest anyways.
- Blind Without 'Em: Stef, although it's really just a couple instances of "I can't see a thing"; it's not really played for comedy or anything and she can see well enough to not be helpless.
- The Glasses Gotta Go: Mouth admits to thinking as much.
- Pay Evil unto Evil: Decides to punch Ma Fratelli in the face before jumping off the pirate ship. Largely because she deserves it.
- Sarcastic Devotee: She complains and snarks about their situation constantly but sticks by Andy regardless.
- Slap-Slap-Kiss She and Mouth have this sort of relationship in The Goonies. At first they hate each other, but then she hugs him when they find the pirate ship and then pushes him back. Finally at the end they really do make up.
- Surrounded by Idiots: Stef doesn't feel like she's in the most logical company.
- Ship Tease: Pretty strong hints towards her and Mouth harboring some feelings for each other.
- Tomboy and Girly Girl: The tomboy to Andy's girly girl.
Lotney "Sloth" Fratelli
- Abusive Parent: Where to begin. Chaining him to a wall like a animal. The heavily implied physical and emotional bullying during his entire life. And the fact he was dropped on his head more times than his mother can actually recall and enough times that mentioning it is Sloth's Berserk Button
- Berserk Button: Mentioning falling and a baby in the same sentence isn't wise.
- Big Damn Hero: Arrives with Chunk to rescue the Goonies from his deranged family.
- Big Eater: He has quite an appetite, which is how he and Chunk first bond. When the Goonies hear Sloth growling, Stef thought it was his Growling Gut.
- The Big Guy: Not just because he's the only adult among the Goonies, but he's also the tallest member of the cast, and he's strong enough to hurl around both of his adult brothers simultaneously.
- Big Guy Fatality Syndrome: Averted when Sloth remains behind to hold up the boulder so the kids can escape, but then later makes it out (with his Ma, like a good son, even though she had been bad).
- Childhood Brain Damage: It's implied that Sloth's deformity was caused by being dropped as a baby. When Ma Fratelli tries to calm him down by singing "Rock-a-bye Baby", Sloth reacts to the line "the cradle will fall" as if it has unearthed Repressed Memories, precipitating his HeelFace Turn.Ma Fratelli: I only dropped you once! Okay, maybe twice!
- The Dreaded: He's the "it" in the basement. Though we soon learn he's no monster at all.
- Expressive Ears: He can wiggle his ears.
- Gentle Giant: Big and strong enough to take on both of his brothers simultaneously and win, but the only times he uses his strength at all are to break out of captivity, help out Chunk (and later, the rest of the Goonies), and administer some Laser-Guided Karma on his abusive family members.
- Gonk: Very unnerving to look at first, then there's the implications that it may of being a result of constantly being dropped by his mother.
- The Grotesque: He is deformed, dimwitted, very strong, and kept as a Madwoman in the Attic by his family. Once he makes friends with Chunk, however, it's clear he's a good guy.
- Happily Adopted: By Chunk and his family. In the film Chunk just says Sloth is going to live with him and we don't see how that goes, but the novelization expands on this.
- Hulk Speak: "Sloth love Chunk!"
- Load-Bearing Hero: Sloth holds up a boulder to let the Goonies escape.
- Madwoman in the Attic: In his case, in the Creepy Basement.
- Misunderstood Loner with a Heart of Gold: It's made clear Sloth has always had a good heart in spite of his family.
- Save the Villain: He still helps his family escape Willy's grotto as it's caving in because he's far too good a person/brother/son to leave them to their fate.
- The Sixth Ranger: Initially just a mysterious "it" that The Goonies are all afraid of, but after Chunk befriends him via understanding and candy, Sloth does what he can to help Chunk out, and this quickly grows into helping the rest of Chunk's friends, too. Affirmed in the finale, when all of the Goonies rush to speak up for Sloth when the police go to arrest him with the rest of his family.
- Sweet Tooth: So much that a Baby Ruth just out of his reach is enough of an incentive for him to find the strength to break his chains.
- Tastes Like Friendship: Bonds with Chunk over their mutual love of Baby Ruth candy bars. Later, they both raid the freezer for ice cream.
- Token Good Teammate: Sloth is the only kind-hearted Fratelli.
- The Un-Favourite: Sure, Jake gets slapped and is openly disparaged compared to Francis, but he's still better off than his brother Sloth, who gets chained up in a basement.
- White Sheep: He's mentally disabled and physically deformed, kept chained in the basement, and not even a candidate to be his mama's Un Favorite. More importantly, unlike the rest of his family he's a good guy at heart, opposing them when given the chance.
- Big, Screwed-Up Family: Mama is openly contemptuous of one of her sons, tortuously abusive of another, and none of her sons seems to like the others, with Jake and Francis ready to pull guns on each other over an argument about food.
- Bilingual Bonus: Fratellis is Italian for brothers.
- Expy: Roughly of the Barker-Karpis Gangnote .
- The Family That Slays Together: They are never actually seen killing anybody, but have stuffed a corpse in the freezer at their hideout, and Ma Fratelli has no qualms with forcing the kids to walk the plank.
The leader of the Fratelli gang, and mother of Jake, Francis and Sloth.
- Abusive Mom: Seemingly to all her children. Though Francis may get off lighter due to apparently being the favorite. But above all her treatment of Sloth is unforgivable.
- Big Bad: As the leader of the criminal gang out to find the treasure as well as evade justice for their previous crimes, to the extent of being willing to kill the Goonies, she's the most immediate looming threat for most of the film.
- Child Hater: "Kids suck."
- Evil Matriarch: Her criminal gang is made exclusively from her children, and her poor treatment of Jake and Sloth show that she's not even kind about that.
- Even Evil Has Loved Ones: She does seem to love her sons despite being an awful mother and person.
- The Family That Slays Together: Mama Fratelli has raised her sons to be killers, thieves and all round scumbags.
- Jerkass: She's abusive to her kids and has no issue with hurting kids, all making for an unpleasant demeanor.
- Parental Favoritism: The pecking order is seemingly Francis over Jake and then way below both of them is Sloth.
- Would Hurt a Child: No qualms about it whatsoever.
Allegedly wears a toupee but strongly denies it. Apparently the 'favored' son.
- Alliterative Name
- Asshole Victim: Deserves any pain that comes his way during the film.
- Ax-Crazy: He's definitely the most violent and bloodthirsty out of all the Fratellis.
- Believing Their Own Lies: "I don't wear a headpiece!"
- Berserk Button: Mentioning his wig.
- Bullying a Dragon: Sloth eventually confronts both his brothers and wins quite convincingly.
- Dodgy Toupee: His hairpiece is especially bad after the various times it gets knocked off his head and he puts it back on.
- Groin Attack: Twice courtesy of Data. The first instance leaves him an Instant Soprano. The second instance involving the "Pinchers Of Peril" is notable in that he needs to physically pry them off with a sword. Ouch.
- Kick the Dog: His treatment of his brother Sloth.
- Sibling Rivalry: Shares a very antagonistic relationship with his brother Jake. They even come to blows.
Broken out of jail at the beginning of the movie. He has a particular fondness for singing Italian opera.
- Asshole Victim: Any tragedy that befalls him during the course of the movie is well deserved.
- Brown Note: His opera singing is....oddly....enough, this.
- Bullying a Dragon: Sloth easily beats both Francis and Jake in a fight.
- Faking the Dead: How he escapes jail. Jake manages to make it look like he hanged himself to lure in an unsuspecting guard.
- Groin Attack: Courtesy of Data's "Slick Shoes" on a log.
- Kick the Dog: His treatment of his brother Sloth.
- Sibling Rivalry: Notably very jealous of Francis' perceived status as the favorite son.
- The Un-Favourite: Mama Fratelli favors Francis over Jake.Jake: "You always take his side, Mama. You always liked him better than me."Mama: (Smacks Jake) "That's right!"
- Body Horror: The reason he's called One-Eyed Willy? He has a layer of bone where his left eye socket should be.
- Doomed Predecessor: The Goonies find his remains in the cave system leading to the Treasure Room. Apparently Copperpot fell victim to one of the Durable Deathtraps. On him, the kids find explosives to set up some booby traps of their own and a skeleton figures "Triple Stone" which they use to unlock a secret room later.
- Eyeless Face: He has no left eye socket, which is covered with an Eyepatch of Power.
- Foil: As Mikey makes clear when finally face-to-face with Willy's corpse, One-Eyed Willy is one for Mikey. Both are fond of making Rube Goldberg Devices, are The Leader for their respective teams, and their prime goal is his treasure hoard. However, Willy was a selfish pirate that condemned all of his allies to death to keep the treasure for himself, while Mikey only undertakes his quest for the treasure to help out his family and his friends' family, and Mikey steadfastly stands behind.
- Greater-Scope Villain: Could be applied to him, having been dead for around 350 years, he plays no direct role in the plot and all that is seen of him is his mortal remains. However the heroes must battle through his traps to reach his treasure and Mikey certainly views their quest as a personal duel between himself and Willy. Also, in his time, Willy was a far greater Big Bad than the Fratellis (he did kill all of his men) and Ma Fratelli seems to regard his corpse with a certain mutual criminal reverence.Mikey: Come on One-Eyed Willy, what does this have to do with the map? Is this just another one of your tricks?
Mikey: We've got you now One-Eyed Willy, we're coming up right behind you!
Mikey: I made it, I beat you.
Ma Fratelli: Thank you Mr Willy, thank you. You've made my day.
- Greed: Insatiable. Would rather kill his own crew than part with any of his treasures.
- Pirate: One with all the traditional trappings such as a ship, gold and an eyepatch.
- Properly Paranoid: Fearing his own men would eventually leave, dividing up the plunder, he slayed them all. One of his crew escaped however, with the map, instructions, and key to one of the traps.
Mrs. Irene Walsh & Mr. Irving Walsh
Mikey and Brand's parents. Both are seemingly distracted by both work and the impending forced eviction from their homes. Their mother is very protective of Mikey and might even be exaggerating the extent of his asthma. Their father is the curator of the local history museum.
- Adults Are Useless: Played with. Mrs. Walsh is likely too distracted by more pressing issues to notice Brand has been tied to the chair rather than he did it himself. Though she immediately flips her lid when she realizes her youngest son is up to no good. However this is less because she knows what he's up to and more because she doesn't want Mikey out in the cold. Furthermore Mr. Walsh doesn't have any reason to believe his son hanging out with his friends is anything out of the ordinary when he later sees him.
- Bystander Syndrome: A light-hearted example. When Andy and Brand kiss Mrs. Walsh simply states to her husband that Andy's own mother can bother worrying about the implications, not them.
- Covert Pervert: Mrs. Walsh. Just a seemly average mother who doesn't like messes and frets over the youngest. Her favorite part of Michelangelo's David is the dick. And her children are aware of this.
- Malaproper: Mrs. Walsh, as demonstrated by the quote above, gets her words mixed up at several points. As discussed below under Parents as People, she's got bigger things on her mind than her vocabulary.
- Parental Hypocrisy: When telling off her kids that if they don't clean up they'll be in the "deepest shi..." and desperately trying not to say shit. Brand steps in and helps her out.Brand: "Shit Ma."Mrs. Walsh: "I don't like that language but that's exactly what you're going to be in"
- Parents as People: It's subtle but both parents are strongly implied to be incredibly distracted from what their kids are up to due to the seemingly inevitable loss of their house. Mikey even points out he's well aware that his father sits up all night trying to think of some way to save them.
- Parental Neglect: It's implied they're not around as much as they're desperately trying to find a way not to be evicted. Considering they're actually mere days away from being forcibly removed, it's understandable they aren't quite on the ball. However it's doubtful even on a good day that they'd anticipate the scenario of their kids going off on a dangerous quest for pirate treasure.
- So Proud of You: Mr. Walsh informs Mikey that with his family he already feels like the richest man in Astoria. Somewhat under cut by that jerkass Perkins responding that he is actually the richest but even he can't rain on their parade as it turns out.
Despite having a relatively minor role in the movie, Perkins is actually the main threat to the Goonies' way of life. He wants to develop a golf course where the Goon Docks are currently located.
- Greater-Scope Villain: He's the very reason the Goonies are off hunting a treasure and risking their lives.
- Jerkass: A man willing to evict just over 50 families from their homes for a golf course.
- Kick the Dog: It takes a special level of Jerkass to come in and taunt a man over money when the man's two sons just barely escaped from wanted murderers.
- Near-Villain Victory: He's literally seconds from having Mikey's father sign over his home. But then Rosalita finds Mikey's marble bag...
- Nothing Personal: Comes across like this. He never really seems all that bothered by the fact he's ruining people's lives just so he can add new land to his country club. It's just a bit of business that needs taking care of before he can go about building that course. His son on the other hand, takes great delight rubbing the impending doom in the faces of the Goonies.
- Spanner in the Works: He could not have foreseen the kids going off and finding a priceless treasure, mere moments before he gained ownership of the land. And of course if Rosalita hadn't bothered checking Mikey's pockets, or even took a little longer doing so, he'd have got his hands on the Goon Docks.
- Smug Snake: "You're looking at the richest man in Astoria." Not rich enough though.
The resident Jerk Jock and son of Mr. Perkins. He has a crush on Andy and isn't shy about admitting it. He takes great delight in tormenting the Goonies and openly revels in their eviction at his father's hands.
- The Bully: In addition to his taunts, he made sure to grab Brand's arm to make sure that Brand (on a little girl's bicycle) would get dragged along by his car going at speeds well beyond what the bike could deal with, only to let go so that Brand would be thrown off a ledge. That Brand didn't get seriously injured (or worse) was a minor miracle.
- Bully Brutality: He drives up next to Brandon who is riding a little girl's bike (long story), grabs his hand, and attempts to drag him along before sending him over a cliff. Somehow he survives.
- The Can Kicked Him: Whilst not fatal of course, it's very likely painful as well as humiliating to be launched headfirst into a bathroom ceiling when you've been sitting on the can. Then crying out for your daddy despite being a grown man. And very amusing for the audience.
- It's Personal: Unlike his father, Troy loves to rub the fact that the Goon Docks are about to become a thing of the past—right in the Goonies' faces.
- Jerk Ass: He's quite contemptuous of any of the lower-class Astoria residents. Later he's shown using his car's rearview mirror to look down Andie's shirt and even forces Brand's trike off the road as a gag.
- Jerk Jock: He inherited his Jerk Ass genes from his father. "Come on, Walsh. We don't have all day. There's 50 more houses to tear down after yours."
- He is also a pervert. Attempts to use his car mirror to look up Andy's skirt or down her top, without really bothering to hide the fact. Andy is not impressed and punches him off-screen.
- Laser-Guided Karma: Of all the toilets in all Astoria, the Goonies manage to mess up the plumbing in his and karma finds itself a worthy target.
- Spoiled Brat: Son of the self-proclaimed "richest man in Astoria," got a nice new car upon getting his license, and his treatment of others runs from callous (ignoring Andy and Stef's pleas) to downright violent (the stunt with Brand and the bike).
- Water-Geyser Volley: This happens to him while he is in the bathroom, and Mikey and the others were fooling around with the water pipes.
An Hispanic cleaner hired by Mikey's mother to help them move out and leave the house clean "before they knock it down." She doesn't speak any English.
- Chekhov's Gunman: Rosalita accidentally finds the salvation of the Goonies in Mikey's marble bag mere moments before they lose everything.
- Language Barrier: Rosalita only speaks Spanish. Fortunately Mouth is available to translate for Mrs. Walsh. Unfortunately he takes this opportunity to deliberately mistranslate everything Mrs. Walsh says for his own amusement. Later on her inability to speak English actually becomes a dramatic Plot Point when she becomes too excited and speaks too fast for Mouth to translate quickly.
- Spanner in the Works: If Rosalita hadn't bothered checking Mikey's pockets or decided to check them a little later Perkins would have gotten his hands on the Goon Docks.
Understandably (and justifiably) doesn't believe Chunk when he tells him he's locked in the Fratellis' basement. That is until the phone call gets abruptly cut off causing him to believe something is amiss. But he still doesn't believe in the pirate ship until he (and everyone else) saw it out on the sea.
- Arbitrary Skepticism: Okay so Chunk wasn't lying about the Fratellis but a half dozen youngsters agreeing with him about a pirate ship filled with treasure are clearly embellishing the escape from the Fratelli gang. Despite having just seen priceless diamonds. He literally doesn't believe it until the ship appears before his eyes.
- Crying Wolf: Why he doesn't believe Chunk's story.
- Cut Phone Lines: Subverted in that it's Chunk who accidentally cuts off his own line mid-call. However when he does this the Sheriff begins to suspect something is actually amiss and sure enough begins sending his people out for the kids.
- Oh My Gods!: His reaction upon seeing Willy's ship.Sheriff: "Holy Mary mother of God!"
- Not Now, Kiddo: Fratellis, treasure, and Pirate ships. Don't exaggerate, kids.
- Reasonable Authority Figure: He's understandably skeptical over Chunk's claim of being trapped by fugitives (given Chunk's prior prank calls to him). But when the call gets cut off, he immediately forms a search party.
