Hefty Smurf (original French name Schtroumpf Costaud) is one of the main characters of the Smurfs comic books, the 1980s Smurfs cartoon show, and the 2021 Smurfs cartoon show.
Character
Hefty is naturally extra strong, and he believes that with great power comes great responsibility. His bulging muscles make him feel protective of and responsible for his fellow band of Smurfs, even if they don’t believe they need protecting. This also means he can lose patience, and falls short in the humor department, taking everything quite literally. He’s the straight guy.
It's easy to spot Hefty since he isn't modest about his physical prowess and likes to show off by flexing his muscles. He's always happy to lend a helping hand to a fellow Smurf, doing the heavy lifting with a smile.
Hefty's biggest weak spot? Smurfette. Whereas all the Smurfs adore Smurfette, Hefty has a huge, secret crush on her - though secret in his mind only. He's very shy around her, fumbling his words and turning bright red.
In "Smurfette Overdoes It!", Papa Smurf has remarked as Hefty not always being as needed as other Smurfs, so he claims that Hefty's job is lifting weights to stay active.
He spends his mornings exercising, and his house is full of work-out equipment. Hefty is also the most athletic of the Smurfs, able to climb up tall trees and bring down whatever is up there without much effort. However, in "Smurfy Secrets", it is revealed that Hefty greases his chest to look strong.
He is easily identified by the heart tattoo on his right upper arm, although it sometimes appears on the left upper arm or both upper arms. In the 1981 series, his heart tattoo had an arrow shot through it. In "Grandir avec les Schtroumpfs", the 2017 film Smurfs: The Lost Village, and the 2021 series, he has a noticeable toned upper body. Prior to "The Jewel Smurfer", the only thing that visually separates Hefty from the other Smurfs was his tendency to carry around a halberd.
He can manage to bend things that only can be bent with machines, such as metal poles.
Role In The Village
Hefty mainly carries the heavy load that other Smurfs can't. He is also one of the few Smurfs who will accept any kind of dangerous journey, making him one of the top choices to send out of the Village to retrieve something.
Personality
Hefty is known for being heroic, brave, earnest, trustworthy, confident, friendly, protective, and strong-willed. Despite his friendliness, Hefty is also prone to getting aggressive, as he is the main Smurf to give Brainy a clobbering in the comics and a toss out of the village in both cartoons. If he feels provoked or intimidated by anyone (or anything), Hefty often feels the need to either prove his strength or deliver a pounding.
Hefty's aggressiveness tends to bring out the worst in him. In "A Smurfy Christmas", he considers and later tries to beat up Jokey for deliberately mixing up the Christmas letters.
At the beginning of "Hefty's Heart", Hefty has a noticeably nicer attitude than most episodes, as he is shown helping Lazy and Brainy without any irritability and sings about how he loves helping his friends while out chopping firewood in the forest.
After breaking his leg in "Hefty And The Wheelsmurfer", Hefty is left temporarily bed bound. While at home, Hefty refuses to let his fellow Smurfs (except Smurfette and Baby Smurf) visit at first, embarrassed to be seen in such a vulnerable state, feeling miserable and lost without being able to walk around and exercise as usual.
A more negative trait for Hefty is that he sometimes thinks with his muscles rather than with his brain. In "Mirror, Mirror On The Armoire", when trying to save Brainy and Blossom from Gargamel's magical armoire that will lock up anyone who looks at it, he shows off his muscles, but he is captured when he winks to the mirror. He can also be very persistent, shown in "Ogre Love", where he repeatedly tries to stop Bigmouth from taking Smurfette and even after he is consistently hurt, he tries to go with Papa Smurf, Handy, and Brainy to Bigmouth's house to save Smurfette.
Hefty also has a slight ego, though not as bad as Brainy. This ego often makes him accidentally forget his fellow Smurfs' feelings. In "Curing Private Timid", he takes Timid under his wing to teach him some self-confidence. Despite Timid's easy-to-notice reluctance and Smurfette's warnings, Hefty doesn't listen, causing Timid to run into the forest and gets caught by the ogres. When the two ogres are driven away, Hefty apologizes to Timid.
Hefty is usually fearless, causing him to feel equally lost when he has fears of his own, such as the fear of heights he develops in "A Circus For Baby" when he accidentally gets launched onto a high tree branch while trying to practice his tightrope walking act. Oddly, he is first shown to have this fear in "The Secret Of The Village Well", as he's very nervous about being lowered into the well to find a penny. Hefty's fear of heights makes a return in "Smurfquest", in which Grandpa Smurf gives him some encouragement and a blindfold.
Relationships With Others
Handy Smurf
Hefty's closest friend is Handy. The two share a "Brains and Brawn" friendship, making work in the village a lot easier for them and everyone else.
Being ambitious and incredibly skilled in their own areas, Hefty and Handy jump at any opportunity to see who's the better Smurf through a little friendly competition. They occasionally take this a bit too far, but the two have each other's backs despite their rowdiness and teasing. This is showcased best in the special "The Smurfic Games" and episodes such as "Romeo And Smurfette".
In "Smurf The Other Cheek", Hefty visits Handy and begs to rid him of the red spot with a kick. He claims Handy is his closest friend and also refers to him as "ol' buddy, ol' pal" twice throughout the episode. When Handy knocks the spot off Hefty's nose using an indirect kicking machine, he ends up receiving it anyway. Moping on the Smurf River Bridge with Handy, Hefty admits he doesn't feel any better as his friend is just as unhappy as he was. He has Handy pass the spot back to him, then the two decide to go to Papa Smurf for help.
In “Hefty And The Wheelsmurfer”, Handy is the one to make Hefty the wheelsmurfer and leave him with the decision of whether or not he wanted to get up and use it, as Hefty initially refused to.
Jokey Smurf
Jokey tries to cheer up a heartbroken Hefty in "Gargamel Goes Gaga".
Hefty and Jokey are relatively close friends, though Hefty is frequently annoyed by his pranking behavior. In "A Smurfy Christmas", he briefly attempted to beat up Jokey for deliberately mixing up the Christmas letters.
Jokey usually tries to help Hefty feel better whenever he's heartbroken and also helps him in his attempts to win Smurfette's love as seen in "Gargamel Goes Gaga" and in "Who Nose?". In "Smurf The Other Cheek", Hefty goes to Jokey for help with his spotted nose, indicating that Jokey may be one of Hefty's closer friends. Hefty is also one of the Smurfs who attempted to rescue Jokey in "The Jewel Smurfer".
Tuffy Smurf
In Season 4, Hefty has a fan in the form of Tuffy, who aspires to be like him, yet acts far more reckless and easier to provoke than he is. In "Gargamel's Giant", Hefty comments that he's always getting Tuffy out of messes. Given Tuffy's four appearances, this is not shown again or brought up in a later episode.
Smurfette
Hefty flirting with Smurfette in "Who Nose?".
Hefty has a secret, yet obvious crush on Smurfette.
Hefty meets Smurfette for the first time in "The Smurfette".
In the 1981 TV series episode "The Smurfette", he is shown to have been the first Smurf to meet her after she was created by Gargamel. Much like the other Smurfs, Hefty is shown to have a romantic interest in Smurfette as he is usually seen vying for her attention with the other Smurfs whenever dances or the chance to marry her come up.
(Bottom) Smurfette and Hefty sharing a milkshake in "The Smurfwalk Cafe".
Though Smurfette doesn't display specific interest in any Smurf in particular in the 80s series, she did share some subtle romantic moments with Hefty. A couple of these include sharing the same milkshake with him in “The Smurfwalk Cafe” and dancing with him in "Brainy's Smarty Party".
The two are really close friends in general and are almost always seen spending time together. Smurfette would often swoon over his strength and bravery as well. Namely because he was the one Smurf who would normally rescue her from danger, as seen in episodes like, "The Noble Stag", "Smurfette's Dancing Shoes", “The Golden Smurf Award”, and "Like It Or Smurf It" (where she rescued him first, and he rescued her back).
Hefty rescues Smurfette after she saves him in "Like It Or Smurf It".
Smurfette often turns out to be a voice of reason to Hefty. Whenever Hefty may lose his temper with another Smurf (usually Brainy), Smurfette tries to calm him down and reminds him that he should be tolerant and considerate of others. Notable examples of this are from the episodes "He Who Smurfs Last" and "Papa For A Day." In "He Who Smurfs Last," Hefty assists Smurfette move some rocks to build her a stone wall around her garden. Jokey then comes in and pranks Hefty, first by making him lift a balloon "rock" and then by scaring him with a Gargamel jack-in-the-box. An angry Hefty tries to give him a pounding only for a giggling Smurfette to hold him back and tell him to have a sense of humor. Worried that he might not have one, he listens to her and tries to have one later on. In "Papa For A Day", after Hefty grows annoyed with Brainy's poor attempts to play Papa Smurf, Hefty claims it's his turn to play Papa and tries to literally kick Brainy out of the underground storage mine they're working on, but Smurfette reminds him that being Papa means being tolerant of other Smurfs, including Brainy. Though hesitant, he listens to her and utters that being Papa is going to be a lot harder than he thought.
Smurfette stops Hefty from beating up Jokey in "He Who Smurfs Last".
In the 2021 series, Hefty and Smurfette's relationship is mostly the same as it was in the 80s series. The most notable difference however is that Hefty is now the only Smurf who has legitimate feelings for Smurfette.
Though he did already have a crush on her in the 80s series, his crush wasn't as defined as it is now. For example, in the 80s series episode "Prince Smurf", Hefty seemed uninterested in competing for Smurfette's affection to take her to a dance. Ironically though, he's the one she chooses to be her date after she sees him wearing the "smurfy" outfit that the Trokles gave him. In the 2021 series however, Hefty is willing to do anything and everything to gain Smurfette's attention and affection as seen in the episode "Who Nose?". In the episode, Hefty wants a new nose in an attempt to impress her after he believes his own nose is unattractive.
Despite him having a definite crush on her in the 2021 series, his first actual instance of displaying a stronger crush on her was in the 80s series Season 9 episode, “The Smurfs Of The Round Table'' wherein Hefty shows open jealousy of Smurfette’s obvious attraction towards Sir Lancelittle (Sir Lancelot shrunken down). In the episode, Hefty is the only Smurf who grows jealous and tries to compete against Lancelittle for Smurfette’s affection, even though other Smurfs are also aware of Smurfette’s interest in the shrunken knight. The episode is perhaps the only or at least one of the few instances of the 80s series in which only one Smurf grows jealous of Smurfette displaying open attraction towards another male, as in most episodes it’s usually a handful of Smurfs that become jealous together.
Hefty injured after trying to protect Smurfette from Bigmouth in "Ogre Love".
Hefty is also shown to be very protective of her, which causes Smurfette to grow annoyed with him at times – namely because she's a bit more independent now. She does seem to appreciate it sometimes however, as seen in "Clumsy Not Clumsy" where she kissed Hefty to thank him for saving her from Gargamel. Hefty can also be protective to a fault, as seen in "Ogre Love" wherein he's injured multiple times after he tries several poor attempts at keeping the infatuated Big Mouth away from Smurfette.
Hefty has also been shown to be very jealous whenever Smurfette shows interest in anyone else. In "Knight Smurfalot", he grows jealous of Dreamer when Smurfette offers him a rose after he charms her. Similarly, Hefty bashfully admits to Smurfette that he grew jealous of Painter because he got to spend so much time with her in "The Stolen Portrait".
Hefty shocked that Leaf heard him reciting his love poem for Smurfette in "Gargamel Goes Gaga".
Though Hefty tries to keep his love for Smurfette a secret, it seems to be common knowledge amongst the other Smurfs. As such, the others (namely Jokey) tend to tease him about his obvious crush.
It is unclear if Smurfette is aware of Hefty's feelings. In the Halloween episode, "The Magic Pumpkin", Smurfette knows enough to give Hefty puppy dog eyes when asking him to be scared of Wimpy. So perhaps it does display some awareness on her part in knowing that he'd do it simply for her sake. Namely considering the fact that she does not attempt this tactic with the other Smurfs when asking for the same favor. On the other hand, she does seem completely oblivious of his intentions in the Valentine's Day episode "Gargamel Goes Gaga", when Hefty tries to confess his love for her through a poem he wrote.
Smurfette seemingly enjoying Hefty's flirtations in "Lost Cat".
Similarly, it's unclear if she reciprocates his feelings or not. In the same aforementioned episode ("Gargamel Goes Gaga"), she unknowingly friend-zones Hefty after he fails to recite his poem and simply accepts his friendship and a box of chocolates he gifts her. It should be noted however, that she does kiss him at the end of the same episode after she gratefully thanks him again for the chocolates. She also doesn't seem to mind him openly flirting with her, as seen in "Lost Cat" where he even brings his face right up to hers and she appears to be enjoying his flirtations. It is interesting to note as well that unlike the 80s series where Smurfette would kiss numerous Smurfs – either as a sign of attraction, gratitude, or relief – up into "Smurf vs. Machine" with Diaper Daddy, Smurfette has only ever kissed Hefty in the 2021 series.
Smurfstorm
Hefty and Storm engaging in one of their many fights.
Storm is Hefty's female counterpart as she is the strongest and most athletically skilled of the Smurf girls. Storm and Hefty are good friends, but they are also very competitive against one another when it comes to tests of skill and strength. In one of their earliest interactions in "Challenges For Hefty Smurf" in the Smurfs: The Village Behind The Wall comics, Storm suspects Hefty of being a liar, accusing him of completely making up all his tales of bravery. She thinks she's been vindicated when he balks at fighting the Gobble-All but changes her mind upon seeing him race in to save Brainy. After those events, Storm came to respect Hefty, even suggesting he become an honorary member of Smurfy Grove.
Hefty trying to defend Smurfette's honor from Storm in "Wanna Bet?".
Due to her competitive nature, Storm can be very spiteful and envious if she loses a competition as seen in the comic book, "The Betrayal Of Smurfblossom", where after being bested by Hefty, she grows angry with both him and Blossom (Blossom for acknowledging Hefty's skill) and decides to make up a false rumor that Blossom likes Hefty in an attempt to embarrass them. She eventually apologizes to them both and is relieved to have made up with Blossom as her spitefulness almost put her in danger.
Hefty is willing to challenge – and possibly even fight – Storm if it means defending Smurfette’s honor as seen in the episode, “Wanna Bet?” when Storm doesn’t let Smurfette train in “her” training area. Hefty can become a bit intimidated by her though as he then decides to train elsewhere with Smurfette after Storm aggressively threatens him with one of her arrows.
Smurfblossom
In "The Betrayal Of Smurfblossom", she was accused of having a crush on Hefty Smurf, but she never showed any special attention to him. It is likely Smurfstorm was just jealous that Smurfblossom acknowledged Hefty Smurf's skill.
Hefty and Blossom were partners in the Pumpkin Race in "Smurf Racers" and Hefty chooses her on his smurfball team in "An Unsmurfy Friendship".
Brainy Smurf
Like everyone else, Hefty's worst friend is (in spite of being smarter than Hefty and his annoyance) probably Brainy.
In both cartoons, Hefty is frequently seen in disputes with Brainy in episodes such as "Diaper Daddy" and "Doctor Brainy & Mister Dumb". Mainly because Brainy loudly bosses the other Smurfs around including Hefty, often cluelessly. However, Hefty has often helped Brainy, especially in times when Brainy's life appears to be in danger. One example: in "'Tis The Season To Be Smurfy", Brainy was about to be attacked by a hungry town rat, which Hefty prevented from attacking by tying its tail to a hook. In the comic book story "The Smurfs Of Order", Hefty and Brainy teamed up together as a pair of police Smurfs to arrest and give Smurfs tickets for breaking various laws.
Scaredy Smurf
Scaredy has been seen with Hefty on occasions. In "The Sky Is Smurfing! The Sky Is Smurfing!", Hefty takes Scaredy with himself to see what's the cause of strange weather. He is one of the Smurfs saving Scaredy in "Bubble, Bubble, Smurfs In Trouble". In "Smurfs In Disguise", he and Hefty disguise themselves as girls so they do not have to face the wrath of Papa Smurf when they accidentally break his telescope. In "A Thief Among Us!", Hefty agrees to lookout for Scaredy when a "thief" (which later turns out to be him) steals their things.
Vanity Smurf
Vanity usually gets kicked out of the village by Hefty, who views his constant announcements where he boasts about his own good looks as annoying. The sentiment is also shared by many of the Smurfs, as Vanity often makes these announcements while the Smurfs are doing important work, which is seen in "A Loss Of Smurf".
In "Leaping Lizards", he and Smurfette search for Vanity, who has turned into a lizard, in the forest together.
Wild Smurf
In "Hefty's Rival", Wild amazes several Smurfs, including the little Smurflings, which made Hefty jealous. When Papa Smurf assigns the two on a quest, they end up bonding and Hefty and Wild become friends.
In Other Animated Features
Cartoon All-Stars To The Rescue
In the cartoon show crossover "Cartoon All-Stars To The Rescue", Hefty has a line to sing in the group song, "Wonderful Ways To Say No", although in that instance he lacks his tattoo mark.
In The Movies
The Smurfs
Hefty has a brief appearance in the 2011 Smurfs movie, as his role was given over to Gutsy who is one of the movie's main characters. He is one of the Smurfs featured in the movie opening and later goes with the rest of the Smurfs to defeat Gargamel. Upon Clumsy saving the day, Hefty congratulates him.
The Smurfs: A Christmas Carol
Hefty appears as a major character in The Smurfs: A Christmas Carol, being the Smurf of Christmas Future, whose purpose is to show Grouchy what his actions will cause. He then sees that the village is empty and desolate, that there is no Smurf left in it. He finds out that the Smurfs have gone out into the forest on Christmas Day to get a new tree in the hopes that it would help Grouchy get his Christmas spirit back, and that they have never returned. He goes out to the West Forest, where the Smurf of Christmas Future says the other Smurfs have gone to and discovers that they have been captured by Gargamel, including Papa Smurf when he went out to find them. Grouchy realizes how selfish he's been before then the Smurf of Christmas Future disappears.
The Smurfs 2
Hefty has a brief appearance in the early and late parts of The Smurfs 2 and was one of the three originally chosen by Papa Smurf to journey to modern-day Paris in order to rescue Smurfette from Gargamel (the other two were Brainy and Gutsy) but was accidentally left out as the smurfportation crystals used for traveling through time were instead ingested by Clumsy, Grouchy, and Vanity.
The Smurfs: The Legend of Smurfy Hollow
Hefty has a supporting role in The Smurfs: The Legend Of Smurfy Hollow. He, Clumsy, and Panicky are out in the forest at night with a cart full of smurfberries that has a broken wheel. Unable to fix the wheel, the three of them sit together around a campfire roasting smurfberries and tell a scary story.
By the end of the story, Hefty claims that he wasn't scared, but finds himself jumping into Narrator's arms at the sound of a bat screeching. Clumsy sees that they are now surrounded by bats, which scares all four Smurfs and sends them running back to the village.
Smurfs: The Lost Village
In Smurfs: The Lost Village, Hefty plays a much more prominent role, serving as one of the most prominent of the Smurf Village inhabitants and as part of a team that also includes Brainy (with whom he shares a mutually antagonistic relationship), Clumsy, and Smurfette. After a mishap with Brainy's Smurfy Thing Finder, Hefty tries to cheer up a down Smurfette by suggesting that they all go Smurfboarding. In the process they encounter a mysterious Smurf out in the woods, and are then captured by Gargamel, but manage to escape after learning of the existence of a second Smurf village apparently located in the Forbidden Forest by a trio of trees. Papa Smurf forbids the group to pursue the mystery and grounds them all, but Smurfette sneaks out of the village and is followed by Hefty and the others, who are determined to help her.
After encountering some of the curious flora and fauna of the forest (including Dragonflies), the group run into Gargamel, Azrael, and Monty and are driven into a tunnel network, from which they eventually escape with the help of some glow-in-the-dark bunnies including one that they name Bucky. Arriving at a bizarre, gravity-defying river, the group build a raft and set sail only to be attacked by Gargamel yet again; when his raft sinks, Smurfette and Hefty decide to help him despite Brainy's misgivings. The wizard subsequently betrays them, and all four Smurfs end up in the river, going over a waterfall and landing in a small cove where Brainy takes his two friends to task for their decision to help Gargamel. The four are then captured by a group of what prove to be Smurf Girls, who are the inhabitants of the village of Smurfy Grove, and then learn from their leader Smurfwillow that the "trees" Gargamel is searching for are in fact waterfalls, the image having been viewed by him upside down.
While Smurfstorm, a female Smurf who puts on as tough a front as Hefty, takes Clumsy on a ride to check on Gargamel's progress, the other three are welcomed to Smurfy Grove, where the female Smurfs are quite intrigued by their previously unknown male counterparts. Still angry at each other, Brainy and Hefty engage in a series of sabotages, each trying to make the other look bad in front of the Smurf Girls, though they eventually reconcile. Hefty is then concerned when Smurfette, enamored of the village, seems interested in remaining with the Smurf Girls rather than returning to Smurf Village. Stormy then confronts the group, having learned of Smurfette's origin as a creation of Gargamel, shortly before the Smurf Girls ambush Papa Smurf as he arrives in search of his four charges.
Sadly, Gargamel arrives and captures all of the Smurfs in Smurfy Grove except for Smurfette, whom he leaves behind feeling that she is of no use to him. Hefty and Brainy are able to escape when Gargamel begins the process of draining the Smurfs of their inherent magical energy and come to Smurfette's aid when she tricks Gargamel into attempting to turn her evil again. However, the act of saving her fellow Smurfs causes her to revert back to her original form of a lump of clay, which Hefty carries back to Smurf Village to be mourned by Smurfs and Smurf Girls alike. However, their combined magical power, unleashed by their sorrow, restores Smurfette to life, much to the joy of Hefty and the others, who then celebrate.

Appearances
Trivia
- He was the first Smurf to suggest getting revenge in "Revenge Of The Smurfs", to the surprise of Papa Smurf and the others (who were seemingly uneducated on the word).
- Hefty appears in the 1960s cartoon series and The Smurfs And The Magic Flute without his trademark tattoos, given that these pieces of media were produced before the 1980s cartoon show. He goes by the name Strongman Smurf in the United Kingdom English dub.
- In the comic books since "The Jewel Smurfer", Hefty wears his heart tattoo on his right arm while in the 2011 Smurfs movie and The Smurfs: A Christmas Carol he wears it on his left arm. In the 1980s cartoon show, Hefty's tattoo can be seen on both arms in several episodes.
- Despite being one of the main characters of the 1980s series, his appearances slightly decrease starting from Season 6. Strangely, he does not appear in the lineup of Smurfs in the credits in Season 8.
- As Hefty did not have a tattoo until the cartoon show, he tried to masquerade himself as a rebel in the comic book version of "King Smurf" by not wearing the king's medal. Because of that, he was ambushed by other Smurfs wearing medals and nobody believed he was Hefty Smurf until he gave them a good licking.
- Hefty is the only Smurf to have a tattoo, a red heart to be exact.
- In The Smurfs: A Christmas Carol, it is revealed that one of Hefty's favorite foods is fruitcake.
- In "He Who Smurfs Last", Hefty claims to like riddles.
- Hefty seems to not be the best at archery, as stated in "The Crow In Smurfy Grove". This appears to be referenced in "Storm Loses Her Mojo", where Storm jokingly tells Hefty not to cause an accident while doing archery.
- When the animated series was being made, Peyo was against the Smurfs having personalized, distinguishing features, but allowed them in most cases. In the case of Hefty Smurf, he opposed a few designs, including him dressed in a leopard-print skin like a circus strongman (however, this custom was used by Handler Smurf in comic books), so it was changed to the heart tattoo.
- Other scrapped early designs for Hefty include one where he wears a white vest (as seen on some merchandise like VHS tapes by WorldVision and the "Grandir avec les Schtroumpfs" comic book collection) and a design where his hat is covered in a pattern of black triangles, with or without a white tank top and belt following it.
- The biggest difference between Hefty and Tuffy is Hefty is more about strength and brains combined together, while Tuffy has more of a 'put up your dukes' attitude. However, Hefty has been seen throwing his fists around saying "Let me at 'em! Let me at 'em!" in the past, so it's more likely Tuffy's behavior was inspired by Hefty's in the seasons prior to Season 4, or most notably, Season 1.
- The only Season 1 episodes of the 2021 series not to feature Hefty are "Smurf Your Seat Belts!", "Joke's On You", "Kitchen Klutz", "Adventures In Smurfsitting", "Lab Assistant", "Funny Mommy", "Crashing Gargamel's Party", "Smurfboards", "Pop Out!", and "Smurfy Mother's Day!".
- The only Season 2 episodes of the 2021 series not to feature Hefty are "Back To Nature", "Blossom Goes Wild!", "Souffle Shuffle", "Smurfy Magic Duel", "Papa Smurf Leaves The Nest", "Brainy Gets Ghosted!", "Wild Gets Tamed", "Dreamer: Master Of Love", "The Yummyus Pie", "Smurfs Might Fly", "Leaf's Under The Weather", and "House Call".
- In the Polish dub, Hefty is voiced by Ryszard Olesinki for the whole show (old and new dub). He later dubbed the voice of Scooby Doo in its TV airings of shows (Frank Welker eventually took the role after Don Messick passed away).
- Hefty has his name in six episode titles in the 1980's series which are "Sir Hefty", "Hefty's Heart", "Hefty And The Wheelsmurfer", "Hefty's Rival", "Bananas Over Hefty", and "Hefty Sees A Serpent".
- Hefty has his name in two episode titles in the 2021 series which are "Who's Heftier?" and "Hefty Baby".
- He, Papa, Grandpa, Baby, Smurfette, Brainy, Clumsy, Handy, Greedy, Grouchy, Lazy, Vanity, Jokey, Painter, Wild, Sassette, Snappy, and Smoogle are the only characters who time-traveled during Season 9 with the Time Scrolls.
- He, Papa Smurf, Brainy, Grouchy, and Lazy are the only characters to appear in every incarnation of the franchise.
