Harold Norbert Cheever Doris McGrady V, labeled The Dweeb, was a camper on Total Drama Island as a member of the Killer Bass. He was also a cast member on Total Drama Action, and was placed on the Screaming Gaffers. He later competed on Total Drama World Tour as a member of Team Victory. He was seen with the original contestants on a yacht in the first episode of Total Drama: Revenge of the Island.
A tall, skinny, awkward-looking guy, Harold takes immense pride in his numerous "mad skills." Although he isn't much to look at and is often disrespected by many of the other contestants, including his own teammates, Harold is actually an incredibly resourceful young man of many talents and has won several challenges, either for himself or his various teams. Harold's geeky interests, his somewhat poor personal hygiene, and his know-it-all personality often make him an outcast amongst his fellow contestants and a perfect target for bully Duncan. Although Duncan hates Harold for his uncool ways and Harold hates Duncan for his bad attitude, it appears the two have begrudging respect for one another at the same time. A telling confessional Harold makes in One Million Bucks, B.C. points out that both are willing to put their differences aside when forced to work together. In Total Drama Island, Harold develops a crush on Leshawna and, although she is initially put off by the strange boy, she eventually comes to see him as a true and loyal friend.
Harold arrives in Not So Happy Campers - Part 1 with his keyboard. He is impressed with the condition of the camp, saying that it is "more favorable to his skills." He also (unintentionally) insults Leshawna when she arrives by calling her "big and loud," which prompts her to try to attack him and having to be restrained by DJ and Bridgette. Towards the end of the episode, he is placed on the Killer Bass team.
In Not So Happy Campers - Part 2, Harold has no problem jumping off the cliff for the challenge, and although he lands in the safe zone he also lands on his crotch, causing even the sharks to wince in empathy for his pain. He is not shown much for the rest of the episode, but is safe when his team loses.
In The Big Sleep, Harold walks the twenty kilometer run with Gwen, Katie, and Sadie. He attempts to befriend Gwen, but she tells him not to talk to her. During the Awake-A-Thon, Harold falls asleep rather early. He is later pranked by Duncan who makes Harold wet his pants. When his team loses for the second time in a row, Harold is in the bottom two with Eva, but gets the final marshmallow.In the beginning of Dodgebrawl, Harold walks into the mess hall sporting a drawn on mustache (courtesy of Duncan), earning laughs from everyone in the mess hall. At the beginning of the challenge, Courtney blames Harold for Duncan being asleep thanks to Harold's snoring the night before. Harold participates in the first round of the dodgeball game and tries to throw the ball at Leshawna, but is quickly eliminated by her. Harold is then forced to sit out for most of the game, but Geoff who pities Harold allows him to join the game. Eventually, Harold ends up as the final Killer Bass left on their side of the court opposite Owen of the Screaming Gophers. Owen throws multiple dodgeballs at him which Harold dodges in a fashion similar to the Matrix. Owen throws one last dodgeball at Harold which he catches and wins the challenge. He is then carried off by the other Killer Bass in celebration.
In Not Quite Famous, Harold attempts to audition for the talent show by beatboxing, but is rejected by Courtney before he can even audition. Later, when all the other Killer Bass are unable to do the show due to being puked on or not having a good talent, Courtney and Bridgette reluctantly send Harold up. Harold does his beatboxing which wows everyone including the Screaming Gophers. He gets a perfect score of nine from Chef Hatchet and wins the challenge for the Bass once again.
Harold has no lines in The Sucky Outdoors, but is shown to be scared by Duncan's hook story and is seen glaring at Bridgette angrily when she burnt down the Bass' tent, despite their friendship.
In Phobia Factor, Harold reveals that he has a fear of Ninjas. Later, when he is confronted by Ninjas in the washroom, he takes out a set of nunchucks and begins to use them, only to be then knocked unconscious when he hits himself in the head with them.
In Up the Creek, Harold didn't speak, and he partnered up with Sadie, but Duncan also randomly paired up with the two when they had to canoe to Boney Island. Harold seemed to be worried about it. Harold was responsible for losing his teams oars, by throwing them in the fire out of desperation to win the fire building challenge, however, DJ managed to push the canoes back quicker than the other team, meaning Harold and his team won the challenge.
In Paintball Deer Hunter, Harold was a paintball hunter for the Killer Bass, along with Geoff and Bridgette. Bridgette didn't like the idea of shooting people, but Harold reminded her that Heather was a deer, which convinced Bridgette to participate in the challenge. Later, Harold, Geoff and Bridgette spotted the paintball fight between Leshawna, Heather and Beth and started shooting at them for fun, just as it was announced that the hunt was over.In If You Can't Take The Heat..., Duncan wakes up and notices Harold's used underwear inches from him. Harold denies the underwear is his even though DJ points out his mom sewed his name on them, and as Harold leaves to take a shower, Duncan, Geoff, and DJ decide to teach Harold a lesson. Later, Geoff secretly picks up all of Harold's clothes on the floor with a stick, before going back to the kitchen and signaling DJ, who deliberately spills a bucket of water on Harold. Harold says "Smooth move, Dorkahontas." and Geoff says Harold better change. Later, Duncan and Courtney quibble but are interrupted by Harold entering, wearing his thong underwear with nothing over them, and wanting to know who took all of his shorts. Later, Harold is told by the guys to go back to the cabin for a pair of underwear and shorts, but is unaware the guys have soaked the underwear with hot sauce and when he puts them on, he yells "My biscuits are burning!" and plunges into the lake shortly afterward. Harold enters the kitchen wearing pajamas, but still refuses to acknowledge leaving his underwear around the cabin. Harold takes a bite out of a sandwich offered to him by Geoff, and discovers his underwear in the sandwich. Geoff then says they'll return his clothes when Harold admits to leaving his underwear all over the cabin.
Later on in the same episode, Duncan, Geoff, and DJ drag Harold's bed to the dock while he is asleep. The next day, Harold wakes up stark naked and at the boat dock in presence of the girls (Heather, Courtney, Leshawna, Lindsay, Bridgette, Gwen, and Sadie), who are swimming in the lake giggling at him. Harold shrieks with embarrassment and covers himself with a pillow. He says he'll never leave his crusty underwear around again like before and begs for his clothes back. With that, he gets his pants back and runs to the cabin, hiding himself, to get dressed.In Who Can You Trust?, Harold is partnered with Bridgette for the blind trapeze portion of the challenge. Bridgette is reluctant to jump at first but Harold convinces her to trust him, she jumps and the Killer Bass win that portion of the challenge. When the Killer Bass lose again, Harold is in the bottom two once more, but it is Sadie who is eliminated.
In Basic Straining, Duncan started to prank him once again. In that episode, Harold emerges from the guys' cabin and demands to know who made s'mores with his underwear. Duncan and Geoff laugh in glee at this question and Courtney recoils in disgust when Harold throws the underwear near her path. Later, Geoff uses a fishing line to rip away Harold's underwear, to Harold's consternation in the first challenge where the campers had to hold canoes above their heads. Afterwards, Geoff and Duncan give Harold a glass of apple juice that Harold discovers is actually kitchen grease which annoys Courtney. Harold is eliminated from the challenge during the obstacle course after inhaling too much mud. After Courtney and Duncan sneak some food, Harold finds a happy face made of peanut butter smeared in his bed which further disgusts him. That night he is in the bottom two with Courtney and for the third time gets the final marshmallow. Duncan, Geoff, and DJ are shocked by the news as they all voted for Harold. Harold then appears in the confessional where he is revealed to have switched the votes to eliminate Courtney in order to get back at Duncan for pranking him. The episode ends with Harold smiling evilly into the campfire.In X-Treme Torture, Harold is partnered with Heather for the mud skiing challenge. He successfully grabs his team's flags and Heather cannot make him fall off his ski. Heather then attempts to cut the rope connecting the ski to the jet ski but her top is ripped off by a branch. This temporarily stuns Harold into crashing into a rock, costing his team the challenge. Harold is eliminated that night but does not seem upset, saying that it was fun. Before he leaves Harold confesses his love for Leshawna and is revealed to have been the one that was writing her romantic poems. He and Leshawna then share a kiss before Harold is taken to the Boat of Losers.
In Haute Camp-ture, Harold spends his time hiding from Courtney who was hunting him down after learning that he switched the votes against her. He asks Trent for food which he gives him. He reveals that he wants Leshawna to win but Courtney forces him to root for Duncan after she threatens him.
In I Triple Dog Dare You!, Harold is shown with all the other eliminated contestants by the pool at Playa Des Losers.
In The Very Last Episode, Really!, Harold is shown to be rooting for Owen to win. He has no lines but is shown celebrating Owen's victory.
During Total Drama, Drama, Drama, Drama Island, Leshawna broke up with Harold, saying their relationship went too fast and the moment on the Dock of Shame was just a fleeting, emotional moment. Harold seems to have accepted the break up, though afterwards he promises he will win her over eventually and then rambles on in the confessional about how they will possibly move in together (specifically in his mother's basement) when they are thirty years old. Leshawna so far seems unaware of his intentions. During the challenge to find the million dollar case, he befriended Heather after she opened up about her insecurities after being rendered alone like he currently was. Harold and Heather both qualify for Total Drama Action.
When Harold arrives in Monster Cash, he accidentally bumps into Leshawna, and they share an awkward moment. During the monster challenge, Harold tries to hide under a beach umbrella but is quickly discovered by Leshawna. Later, both Harold and Leshawna are captured by the monster and dropped in the moonbounce. While falling, Harold confesses his love for Leshawna, surprising her.
Despite Harold's claims to have keen senses to allow him to know when someone is nearby, he is completely oblivious to Chef Hatchet being right behind him in Alien Resurr-eggtion and is the first one to be shot down in the challenge. Harold seems to have a deluded view of his relationship with Leshawna, even claiming that she is undressing him with her eyes; meanwhile, Leshawna claims in the confessional (quite confidently) that they are not meant to be. Harold is recruited on Gwen's team, the Screaming Gaffers in Riot On Set. Though he attempts to sell himself by informing everyone of his expert knowledge of movie-making and movies in general, no one seems to care and Gwen only chose Harold if only to shut him up. He was the last castmate chosen for Gwen's team.In Beach Blanket Bogus, Harold is shown to think quite highly of himself and his bottom. Though he is in alliance with Heather, Heather still has no interest in speaking with him. Though Harold frequently speaks highly of himself in his confessionals, he is often met with failure, though he proves to be an expert sandcastle-builder during the second part of the challenge and surprisingly takes a leadership-like role in the project. Unfortunately, none of this visibly impresses Leshawna. He is the one who informs Gwen that Trent became obsessed with the number nine ever since Trent became interested in her. Duncan kicks sand into Harold's face after their team wins the competition, saying it was because he actually had wild dancing moves, but this would only foreshadow worse incidents to come between the two.
As of 3:10 to Crazytown, Duncan has gone back to his ways of regularly torturing Harold like he did last season, but this time he has a reason for it: he found out that it was solely Harold who got Courtney eliminated from Total Drama Island. While Harold continues to be a great asset to his team and again helps them win the western challenge in this episode, he is extremely susceptible to Duncan's constant pranks (Duncan landing on him in a bad position he says "I think I broke my coccyx"), which quickly gets Leshawna's attention. Though she has said that she and Harold were not meant to be, she is becoming angry at Duncan for picking on Harold.
In The Chefshank Redemption, Harold often complains about the prison challenge, and the people around him. After Gwen breaks a shovel over his back, he says that he is both scared and attracted to her, but quickly adds not to tell this to Leshawna, Heather, or Gwen. He, along with Leshawna, Heather, and Gwen herself voted Gwen out of the competition.
In One Flu Over the Cuckoos, Leshawna's friendship with Harold becomes more apparent as she defends him from Duncan's antics. During the hospital challenge, Duncan pulls down Harold's pants and tries to stick a rectal thermometer in his mouth when he and all of the other castmates fall ill and Leshawna sticks up for him both times. However, he refuses to join an alliance with her and Duncan, as he hates the latter bitterly. He is also the first character to reveal their last name: Harold Norbert Cheever Doris McGrady V; he's very embarrassed about the 'Doris' part.
In Masters of Disasters, Harold reveals that he had to have his kidneys swapped because he had a rare kidney condition that had them in the wrong spots. Harold proves his worth by unlocking the hatch of the submarine during the second challenge, using the skills that he had picked up a "Picky Steve's Lock Picking Camp." This saved the entire cast from drowning during the challenge as the whole thing had gone horribly wrong. In addition, Leshawna still might have feelings for Harold, for when Owen was being sent to a hospital in the film lot, Leshawna snuggles with Harold, and when Harold says he has mad skills in unlocking codes Leshawna agrees with him.
In Full Metal Drama, Harold's rivalry with Duncan reaches breaking point as the two firmly believe the other is useless as a teammate. Though Harold tries hard to show his skills and worth, the Gaffers choose to follow Duncan's planning instead. During the third challenge, Harold and Heather attempt to hold back a major gas bubble Leshawna is putting out in an attempt to keep their underground ditch hidden. Leshawna's bloated belly couldn't take the "air baby" filling up her "lovely" stomach, and she gasses up the foxhole. Harold blocks Duncan's way and orders him to admit that he is not completely useless (to which Duncan agrees in order to escape the gassed-up hole). The Grips then charge to capture the Gaffers' chest, Harold prepares for battle with his yo-yos armed. Duncan then forces some gas out of Leshawna, creating a smoke screen and allowing Harold to swiftly knock out the opposing team and win the challenge. Duncan and Harold then admit each other's good skills. When Harold and Duncan open the prize, they find it to be empty.
In Ocean's Eight - Or Nine, he starts to agree with Duncan and Heather about Leshawna, especially when in the confessional, he was seen saying Leshawna was only looking out for herself and stating how bad she was (even though her "badness" intrigued him). During this episode, Harold still gets much grief from Duncan and Heather, as seen by their constant uses of saying "shut up" or "be quiet" to him. During the bank vault challenge, Harold is shown to still have somewhat feelings for Leshawna. As Leshawna was the team member to be left in the vault, Duncan says that their team doesn't need her or the bank robbing equipment inside; as he and Heather leave, Harold said that it was a terrible idea to leave Leshawna, but is unable to convince the other Gaffers. Upon Courtney's return, Harold, ironically, doesn't find this as bad news considering he was the main person she didn't like last season, and she wasn't angry at him. Shockingly, throughout the rest of the challenges, he, the one who was most concerned, did not even ask about Leshawna anymore; causing her to possibly remain in the vault until the next challenge. When the Gaffer's reward is shown ("Chris Bucks") Harold revealed that he hates Chris' smile sometimes.At the start of One Million Bucks, B.C., Harold loses his glasses after taking a shower. He did not believe Duncan's warning about a bar of soap on the floor before tripping on it. While the guys were laughing, Harold loses his towel and tells them that he is comfortable in his own skin. During the first part of the challenge, Harold is chased by prehistoric beavers while Chris, Chef and Duncan watch. Duncan tripped Harold and the beavers grabbed him and took him away until Leshawna managed to save him. Then he is shown around a campfire with Heather, Duncan and Leshawna, while the latter is holding him. In the second part of the challenge, Harold revealed that he has a fear of robotic prehistoric beavers. He later gets attacked by a prehistoric bird because Chris gave him an egg as a consolation prize. Harold and Leshawna tried to cook the egg in the end.
In Million Dollar Babies, Harold had to face Lindsay in the first part of the challenge for them doing the worst in the warm-ups. He was knocked out by her, but won because he did great slow motion. Harold, along with everyone else, were both mad at Leshawna when she made rude comments about the other contestants while she was heading over to the spa with her cousin Leshaniqua from Courtney's PDA. Harold immediately forgives Leshawna when she made an apologetic cheer to everyone and votes Heather off along with Duncan to keep Leshawna safe.
By Dial M for Merger, Harold finally agrees to join the alliance with Duncan and Leshawna, as they help each other through the laser course. The tension between him and Duncan continued to rise as they insulted each other while trying to defuse their bombs.In Super Hero-ld, Duncan puts a burrito in Harold's pocket and kicks it. This causes his back pocket to become all messy and disgusting, much to his annoyance. Justin later convinced Harold (and Duncan) to join in Justin's alliance. Harold also talks about his favorite superhero, Owl Man (possibly a parody to Batman or Night Owl). Harold comes up with his own superhero name, Captain Alberta and was in the lead during the obstacle course challenge, only to lose by Courtney. Harold refused to vote for Leshawna after Duncan and Justin convinced him to do it. He was also asked by Beth to vote for Duncan and by Courtney to vote for Leshawna respectively. In the end, Harold chose to vote for Leshawna and broke down in front of her after it was revealed that she got sent home. Leshawna tells Harold that he should do his best to remain in the show as she leaves. After Leshawna left, Duncan heads over to Harold and tells him that he has another burrito in his pocket and kicks him again. Harold wished that he should do well and Chris pushes him down as he was closing the show, causing Chris to break Harold's glasses.
Harold misses Leshawna in The Princess Pride. He won Duncan's biggest burrito contest after creating a burrito in Leshawna's likeness. Harold was the "Eighth Dwarf" in the blindfolded Bridge crossing challenge. He dedicated his crossing to Leshawna and showed he can run blindfolded. Harold thinks Courtney's song was beautiful and asks for a copy. Harold says that it reminds him of Leshawna but Leshawna says if that song reminds Harold of her, she will have to kill him. During the princess saving challenge, Harold got the shortest sword and helped Justin take down Duncan. Justin later betrayed Harold and Harold was a little miffed. In the end, Harold did say goodbye to Justin.In Get a Clue, Harold is shown to enjoy being a detective and playing dramatic music. He set a trap, in Rube Goldberg fashion, in order to get a DNA sample from Duncan, which ended up failing, causing him to get a sample from Beth instead. Harold also performs CPR on Chris, revealing that he is a trained paramedic. Later in the challenge, Harold teams up with Courtney to try to stop the train, but they do not end up being able to do so. Instead, Courtney is discovered to be the "murderer" and Harold turns on her at the last minute.
In Rock n' Rule, Harold is glad of Owen's return to the show. Harold performs reasonably well in the guitar challenge. However, it catches on fire. In the next part of the challenge, Duncan calls him Doris and he breaks all of the cardboard cutouts, and has a breakdown when finished, Chris later comments saying "If that's not a cry for help, I don't know what is." In the part where the contestants have to trash a hotel room, Harold does very badly, attempting to break a telephone, but failing. He later voted for Duncan to be voted off along with Beth and Lindsay, However their plan failed when Lindsay accidentally voted herself off.In Crouching Courtney, Hidden Owen, Harold, believes his blanket is tickling him while he sleeps until he realizes "blankets don't have souls" and finds out that he is covered in snails. He finds one that (in his mind) looks like Leshawna and names it Leshawna, Jr. Duncan trains Harold throughout the first part of the challenge, but Harold struggles with Duncan's unusual methods. It is during this training when we find out that Harold has a "killer left-hook" when he throws his fist through a punching-bag and grasps Duncan's throat after Duncan claims to have kissed Leshawna to motivate Harold into punching the bag harder during the training. Harold is then up against Beth when the two have to fight in robot costumes. When Harold and Duncan win, the two must climb a steep mountain. He later shows signs of friendship to Duncan, but is reminded by Owen that he should try to win. Owen reminded him by saying that Leshawna, Jr. was telling him something. He surprisingly shows a tough side, and once Duncan says that Leshawna is about as delicate as a freight train, Harold throws Duncan's glass of tea in his eyes and punches him in the face. Harold wins the episode's reward. At the end, Harold lets Leshawna, Jr. into the wild, and was crying like crazy as Leshawna, Jr. was going away.
In 2008: A Space Owen, Harold pulls his own prank on Duncan by filling his mattress with rocks, which results in Duncan getting a sore back. Throughout the episode, Harold winds up with Duncan's pet tarantula, Scruffy, on him. Eventually, he squashes Scruffy by accident during the third challenge, which greatly angers Duncan. He was on the Vomit Comet for the least amount of time though, for about five seconds. Beth also starts to think that Harold likes her and she breaks up with Brady to start a relationship with Harold. Harold says he couldn't date Beth because it wouldn't be fair to Heather or Leshawna, hinting that he still likes them. Beth later kisses Harold (while covered in vomit) and he faints. Harold later does calculations and started to believe Owen was a traitor. Harold is later voted off by Owen to cover his tracks and by Duncan for squashing Scruffy. He was taken away right before he got the chance to count Owen out as a cheater. He did however get to pants Duncan before he left, to which Duncan responded, that he "probably had that coming."
In Mutiny on the Soundstage, he appears at the end with all the other eliminated contestants watching the final two.
In The Aftermath: IV, Harold suggests a contortionist challenge to break the tie. Beth and Duncan go along with it but both end up tying again. Harold's "question" consisted of having the two finalists draw a fictional animal. He likes Beth's Haricorn with wings, but was impressed with Duncan's samurai sword/fighter plane drawing.
In Celebrity Manhunt's Total Drama Action Reunion Special, he gained weight while trying to get a beat boxing career. It is revealed that Harold (along with Justin, Trent, and Cody) were in a boy band called The Drama Brothers and Harold was their beat-boxer nicknamed "H-Bomb." He went solo after Trent insulted his Beat-Boxing talent and then they reunited and released their hit single "When I Cry." He is one of the contestants that doesn't leave to look for help and proceeds to Chris's new season: Total Drama World Tour.
Harold arrives at the airport with the other sixteen contestants in Walk Like An Egyptian - Part 1. When he leaves the bus, he comments on Owen's aerophobia and how it differs from the fear of air sickness, which clearly annoys Noah and prompts him to make a sarcastic comment. When Chris mentions the musical addition to the series, he asks if he would be able to beatbox, to which Duncan angrily retorts at him. He also sang with everyone else in the first song of the season, Come Fly With Us. Later, in the pyramid challenge, Harold wears an aluminum foil hat so that the aliens can't "read his brain,” which Leshawna questions. He chose to go under the pyramid with Leshawna and DJ through the door marked with a scarab symbol. They are swarmed by scarabs when DJ sets off a trap, and they all run out of the pyramid screaming, but cross the finish line in the process. They are the first ones to make it out of the pyramid and are placed on Team One, along with Lindsay, Bridgette, and Ezekiel, which is later named Team Victory. Harold also constantly annoys Chris about how to say numbers in Egyptian.
Harold was upset with his team's color in Walk Like An Egyptian - Part 2. He says that yellow is a cowardly color, but Leshawna tells him that the color is gold. He says he will use the stick from the last episode to protect everyone from sand snakes. While saying this, he stabs Ezekiel in the eye. During the desert race, Harold gets angry and breaks the stick, but discovers it is a divining rod. Harold jumps into his team basket after it was on the river, using a paddle as a springboard. However, he breaks the front of the river reed canoe with his feet by accident. During Rowin' Time he reveals that he was once a Muskrat Boy. He is visibly upset and angry with Ezekiel for losing the stick, insulting him on numerous occasions and stamping his passport many times.In Super Happy Crazy Fun Time Japan, Harold becomes upset with Chris' cultural insensitivity when Chef is dressed up in Chinese clothing rather than Japanese clothing. Harold continues to annoy Chris with his complaining so much so that Chris tells Chef to slice open the door, to which the cast drops out of the plane, upsetting his teammates. In the first challenge, Harold tells his team, but mostly Leshawna, that his knowledge of Japan will help them in the competition. In the second challenge, he takes full leadership of his team's Japanese commercial. He demands that they call him "Sensei" and makes an expressive, artistic commercial. However, Chef, the judge for the challenge, can't understand it, and thus isn't impressed and declares their team to be the losers. After the challenge, Alejandro lets Harold know that he still has his honor and that's what he should be respected for, also mentioning women like Leshawna are impressed by men with honor. This prompts Harold to quit the competition before DJ is eliminated. Harold then "stabs" himself with a toy light saber and takes the Drop of Shame, albeit without a parachute, which Chris throws to him after he falls.
In Anything Yukon Do, I Can Do Better, Harold is seen to have landed safely in Japan, when Chris does the recap. However, he landed in the middle of a sumo wrestling match, into the back of the cloth that a sumo wrestler was wearing. The sumo wrestler farted, and Harold was seen covering his mouth and nose, trying to wave off the smell away from him. Leshawna also mentions him in the episode saying that he left his Num-yo's for her to keep.In Aftermath: Bridgette Over Troubled Water, despite Blaineley's protests, Harold is the first guest, being brought out from the green room by Geoff. After that, a video montage of Harold's time on the show is shown. Harold is upset about the video, complaining about how it's too short, prompting Blaineley to show another video. On the big screen, Harold is shown being punched by Justin after annoying him while he urinates, being kneed in the stomach by Heather after also annoying her, rammed by a moose after he talks to Noah about how moose-hunting is illegal in Alaska, getting punched by a squirrel, after stating that squirrels only blink one eye at time, and having a long line of people ready to hurt him for all his random knowledge. He then sings a song called Baby, dedicated to Leshawna, as a reunion of The Drama Brothers. Harold, Trent, and Justin are then chased out of the aftermath studio by groupie fan girls with plaid skirts in a school bus, according to Eva.
Harold returns in Aftermath: Revenge of the Telethon where he joins his fellow Drama Brothers for back up for Bridgette and Geoff. He later joins the others helping with the telethon, where he starts to check out movie times. His mother donates two hundred out of two hundred and three dollars after Harold promises to clean the garage. After surviving a wild encounter with a large amount of animals that Blaineley set loose (for DJ originally), he later applauds Leshawna as she is introduced. He also takes part in her song, dancing alongside her and Bridgette (and winds up getting kicked between the legs by Leshawna, by accident). After Izzy hits a bomb with a hammer and blows the whole studio apart, Harold is seen lying on a broken light railing.
In Aftermath Aftermayhem, Harold is seen sitting next to Leshawna, and high fives her when she says that she knew Lindsay would remember Tyler's name, thus winning a bet she had with Trent. After Blaineley announces the Total Drama Second Chance Challenge, Harold does not qualify to compete. After Leshawna is knocked out by a kangaroo, Harold says that he will avenge her, and hops into the ring to fight the kangaroo himself, but is quickly knocked out. Along with the other Drama Brothers, he plays the tuba in Her Real Name Isn't Blaineley.
In Hawaiian Style, when Bruno attacks Geoff, he gasps along with the other members of the peanut gallery. Harold immediately joins Cody's team, agreeing with Owen's claim that out of him, Alejandro, and Heather, he is the only person who's not evil. He questions if they'll live long enough to compete, as they are stranded in Drumheller, and he mentions that the greatest cause of death there is being left stranded. When Duncan mentions Ezekiel is like a cockroach, Harold compares Heather to lichen, a substance which never dies. He interrupts Geoff and Bridgette singing Who You Gonna Root For? in favor of Cody, which causes Courtney to join as well, much to the annoyance of Geoff, who states neither Harold or Courtney were allowed to sing, and stops them. When Courtney asks if they can calm Bruno down, Harold suggests using some Kava tea, which he explains is a root the native Polynesians have long used to calm the mind. When Bridgette asks the Peanut Gallery to raise their hands if Alejandro was the reason they were voted out, Harold does, and seems annoyed while doing so, and he mentions that the only reason Alejandro is still in the game is because Sierra blew up the plane. He serves Bruno the tea and mentions that he spent a whole summer learning animal training at Magic Steve's Circus and Aeronautics Camp. He volunteers to compete in the challenge on behalf of Cody, wanting to help him win and show Leshawna his mad surfing skills. When he is forced to choose an animal to represent Cody, he chooses a deer, which amuses the other contestants. He states that he has his reasons. He mocks Courtney for choosing a jaguar when Geoff reveals that they'll have to put a Hawaiian lei around the neck of their animal. He stops to thank a statue of the Hawaiian god Lono, although this allows Courtney and Owen to catch up with him. In the surfing race down the river, he sings I'm Winning This alongside Courtney and Owen. He gets to his animal first, but is disappointed when the deer eats the lei. Despite this, he places second for Cody, winning him a baby carriage to use in the final challenge.
In Planes, Trains, and Hot Air Mobiles, Harold appears with all the other eliminated contestants.In Hawaiian Punch, Harold volunteers to aid Heather in the final challenge, after Cody loudly proclaims Alejandro is going down, saying he's a loyal member of Team Cody. He sings in Versus, calling the competition "evil versus wicked," but he also thinks Heather is cool and calls Alejandro "sick" and that "Heather will put Al through the shredder." Harold later reappears at the river of lava, single-handedly fending off both Lindsay and Courtney from setting off any booby trap that could stop Heather. Courtney then knees him in the groin and releases a trap. When Heather is trapped in the cage, Harold gives a high-pitched support (from pain) of her not giving up. He is later seen with the rest of the cast at the top of the volcano, and is also seen running away from the lava with the rest of the cast again later. He is last seen swimming away from the island with the rest of the contestants.
In Bigger! Badder! Brutal-er!, Harold appears on the yacht with the other veterans. He is seen dancing alongside Leshawna and DJ.

- Harold has three hundred allergies, although the only known ones are crab apples and gummi slugs.
- In Not So Happy Campers - Part 1, he mentions to Chef Hatchet that he gets hypoglycemic if he does not get enough sugar daily.
- Harold seems to know some form of martial arts, having performed several poses throughout Total Drama Island, although during said season, he appears mostly inept at it.
