Clyde Donovan, formerly Clyde Goodman and Clyde Harris, is one of the boys' classmates. He is voiced by Trey Parker. His birthday is April 10, as seen on his Facebook profile page in the episode "You Have 0 Friends". In "Crack Baby Athletic Association" it is revealed that Clyde's mother is Dutch, and as such, he has at least some Dutch ancestry.
Clyde Donovan made his first speaking appearance in "Weight Gain 4000" as an Indian in the play being performed for Kathy Lee Gifford. During "Clubhouses", he began dating Bebe Stevens, though it is unknown as to whether or not this relationship continued - in any case, they briefly got back together in "The List". In the movie South Park: Bigger, Longer & Uncut it is implied that he is not very clever, or at least not good at mathematics and is often portrayed as one of the less intelligent members of the class. When Mr. Garrison asks him what two times five equals, he guesses twelve - Garrison then referred to him as "a complete retard". However, considering that Garrison's teaching skills are almost nonexistent, this probably means that it wasn't Clyde's fault.
In the episode "Cherokee Hair Tampons", Butters comments that Clyde would have helped in getting Cartman's kidney for Kyle, but his appetite for tacos got in the way - referencing his weight, which had also been pointed out by Butters in "Cartman's Silly Hate Crime 2000".
Clyde seems to have a liking for adult-related materials. In the episode "Make Love, Not Warcraft", he is seen reading a Playboy magazine instead of playing the game, and in "Ginger Kids", the topic of his presentation is mentioned as "lesbian cheerleaders." In the episode "Marjorine", Butters (in the character of Marjorine) says that one of "her" hobbies is "Getting my snootch pounded on Friday night", Clyde responds with "Nice.", although he could also have been happy at how well the idea had turned out, although, judging by his tone, this was not the case.
Clyde appears to be one of the nicer boys, or at least he has a better sense of morality at times. In "Cartman's Silly Hate Crime 2000" he appeared to be shocked at himself when he said "I'm not fat, goddammit!" while filling in for Cartman as the fat kid (since he is apparently the second fattest kid in class, although he was shocked by this assessment). In "Lice Capades", he refused to sock bathe Kenny McCormick when Kenny is accused of having head lice, since Clyde believed himself to be the only one who had lice. He also notified Ms. Garrison to stop the sock bathing and tried to delay the other boys until she arrived. Clyde is even seen defending Cartman in "Marjorine". In "Mystery of the Urinal Deuce", Clyde even tried to take the fall for the person (later shown to be Stan) who took a crap in the urinal. Unfortunately, his parents told Mr. Mackey that Clyde had had a colostomy when he was 5, so he couldn't have taken the crap in the urinal. In "HUMANCENTiPAD", Clyde mentions that he takes the time to read the terms and conditions on the Apple store so that he knows what he's agreeing to.In "The List", when Clyde is listed on the corrupted list as best looking, he becomes arrogant and self-loving of his looks. He attempts to make Kyle feel better for being listed last, though does it in a careless way. He, however; is very low on the real list. In "Marjorine", Clyde stood up for Cartman when Kyle and Stan were ridiculing him for his discovery of the girls' future telling device. This surprised many of the boys who were in Cartman's basement at the time, including Cartman himself. Although this initially indicates that he's somewhat on Cartman's side, he ignores him along with the rest of the class in "The Death of Eric Cartman". He may have only been curious about the future telling device Cartman was reporting and wanted Stan and Kyle to be quiet while Cartman explained. He might also still feel loyalty towards Cartman for returning to South Park in "Cartman's Silly Hate Crime 2000", evidenced by his willingness to accept Cartman as a leader, such as when he joined his crew in "Fatbeard". He also seems to be much more willing than the other kids to accept Cartman's bigoted views, possibly because he agrees with Cartman on occasion. He often laughs at Cartman's jokes even if the other kids don't find it funny at all.
In "The Coon", many people saw Clyde as a possible candidate for the identity of Mysterion in the episode. He was shown sleeping in class the day Cartman gave his speech in class, possibly from playing Mysterion, but the next day it is implied this is Mysterion's first appearance. However, all of the children were bored of Cartman's lecture on the Coon, so it served as an illusion. Cartman did accuse Mysterion of being Clyde, making him one of the possible candidates. In the episode "Coon 2: Hindsight" he is present with the rest of the boys in Coon and Friends watching the rise of Cthulhu on television, before showing the now dressed-up heroes leaving, confirming him as one of them - in that episode, the candidates were effectively narrowed down to Clyde and Kenny. In "Mysterion Rises", however, it is revealed that Clyde is in fact Mosquito, the hero who was easily beaten up by Cartman in "Coon 2: Hindsight", with the aid of the element of surprise. Mosquito was often yelled at by Cartman for various reasons, so he was evidently not one of the more steadfast heroes.
In "Lice Capades", he thought at first that he was the only one in the school who had head lice. He did not want to reveal it or have it found out, because he feared he would be made fun of and embarrassed by Cartman and the rest of the class. However, Clyde's lice problem was not revealed to the others, as Kenny McCormick was accused by Cartman (because he thinks that poor people are most susceptible to head lice). This episode was the first time his last name was 'Harris,' as stated at the lice inspection. However, in the later reruns, this was corrected.
Clyde Donovan has been seen as a good athlete and really likes sports. He plays football for the South Park cows in "Big Gay Al's Big Gay Boat Ride" and "The Coon" and continues to show support for the team throughout "Douche and Turd", very upset with the name change and during the change back is shown to wear the jersey under his clothes. He's also on the basketball team in "Elementary School Musical" and was on the soccer team in "Medicinal Fried Chicken".
He was seen playing baseball in "The Losing Edge" where he plays shortstop (which is usually the position of the best defensive player on a baseball team), but like all of the boys at South Park Elementary, hated the game and tried hard to lose it so they did not have to continue playing. Clyde is also a big fan of the Denver Broncos, as seen in "Marjorine." Also, looking closely of his room in "Make Love, Not Warcraft" his lamp is of the Colorado Avalanche, hinting he might be a hockey fan. Supporting this is that part of his costume in "Stick of Truth" are hockey gloves.
He has medium-brown hair, wears a burgundy coat, grayish-brown trousers, and sometimes wears ocean-blue mittens. Underneath, he has been shown to wear a green T-shirt with a cow's face on the front. On occasion, he is seen wearing a sports jacket that looks similar to his usual coat. He has been labeled "the second fattest kid next to Cartman" despite appearing about the same weight as the others. He has a somewhat nasal voice, similar to that of Craig's, but lighter. In "Quest for Ratings", it is rumored that Clyde only has one testicle, though this is never actually confirmed. In "Mystery of the Urinal Deuce", Clyde is announced as having a colostomy by Mr. Mackey, and as such was incapable of and therefore innocent of defecating into a urinal. In reality, people with colostomies are among the most capable of defecating into urinals.

He has a habit of sobbing uncontrollably whenever he witnesses something upsetting. Examples of this are when he hears Cartman singing in "Fourth Grade", when the adults decide to give all of the money they would have spent on Christmas presents for their kids to the Broflovski's in "It's Christmas in Canada", and when he realized that there were no crystal clear lagoons, treasure, and plunder after he joined Cartman's "Somalian pirate club" in "Fatbeard". This usually gets an angry response from Cartman.
On several occasions when things get surreal in the show, Clyde shows little or no interest. For instance, when the boys audition for a new fourth friend, and he is eliminated as a candidate, he eventually decides that it is stupid and shows no actual interest in being their fourth friend. Also, while everyone else is obsessing over the World of Warcraft game, he questions its importance and reads Playboy instead, which causes the "rogue" to defeat the other players once again. During "Dances with Smurfs" he does his homework instead of listening to the murder of Gordon Stoltski on the intercom.
Clyde seems to know a lot about movies. He has Lord of the Rings on DVD in "The Return of the Fellowship of the Ring to the Two Towers". Other examples are in "The Losing Edge" and "The List".

Clyde seems to have a liking for adult-related materials. In the episode "Make Love, Not Warcraft", he is seen reading a Playboy magazine instead of playing the game, and in "Ginger Kids", the topic of his presentation is mentioned as "lesbian cheerleaders." In the episode "Marjorine", Butters (in the character of Marjorine) says that one of her hobbies is getting my snootch pounded on Friday nights to which Clyde responds "Nice.", although he could also have been happy at how well the idea had turned out - judging by his tone, this was not the case.
In "Lice Capades", Clyde was extremely ashamed of having headlice (not knowing that, in fact, everyone had them), even going so far as to tell a little girl at the doctor's clinic that he had AIDS to avoid being found out.
In "Marjorine", Clyde stood up for Cartman when Kyle and Stan were ridiculing him for his discovery of the girls' future telling device. This surprised many of the boys who were in Cartman's basement at the time, including Cartman himself. Although this initially indicates that he's somewhat on Cartman's side, he ignores him along with the rest of the class in The Death of Eric Cartman.

He also seems to be much more willing than the other kids to accept Cartman's bigoted views, possibly because he agrees with Cartman on occasion (he said ginger kids creeped him out in "Ginger Kids")
He told the environmentalists in "Terrance and Phillip: Behind the Blow" that his father, like Randy Marsh, is a geologist (who said there was no evidence of global warming), though Mr. Donovan is only shown with Clyde alongside his mother. The couple appear again in the Atheists Club in "Red Hot Catholic Love", leading us to believe that Clyde's family, like most of South Park's residents, is Roman Catholic. He has a dog named Rex Donovan, who had a sexual encounter with Stan's dog, Sparky Marsh. His mother is referred to as Martha in "Red Hot Catholic Love". His name suggests Irish or Scottish ancestry, however, his mother is Dutch, as revealed in "Crack Baby Athletic Association".
In the season eleven finale, "The List", it is revealed that his father owns a shoe shop. This is why the girls declared him the cutest boy in South Park Elementary; it was so that they could have easier shoe-shopping sprees. However, as mentioned above, Mr. Donovan was supposedly a geologist. Of course, he may have more than one job, or he may have quit geology since "Terrance and Phillip: Behind the Blow", and taken up a career as a shoe store owner. Another version of this goof is that he is not Clyde's real father at all.
In the episode "Reverse Cowgirl", shortly before her death, Clyde's mother mentions that he has a sister, asking him to put the toilet seat down next time for his sister's sake.
Clyde's last name appeared on merchandise during the first few seasons as 'Clyde Goodman', but this name was never used on the show. During "Quest for Ratings", he was referred to as Clyde Donovan during a news segment, yet a few seasons later during "Lice Capades" the nurse asks him "Clyde... Harris, is it?" and while it may have been a mistake on her part, later airings corrected the line to Donovan. In "You Have 0 Friends" on Facebook his name is changed back to 'Clyde Donovan'.
Craig TuckerClyde seems to get on with Craig quite well. He even seems to lead Craig's Gang from time to time, even though Craig is the confirmed leader. Normally, though, the two just hang around with each other. The two are often seen with each other, showing that they are likely good friends.
Clyde and Craig are seen together in a number of episodes whether they were sitting next to each other or just talking to each other including "Crack Baby Athletic Association", where they are seen working together for Cartman in looking for Slash, in "The Last of the Meheecans", where they are working/playing together again for Cartman by not letting any Mexican pass their border (which they unfortunately failed in doing), in "Elementary School Musical", where they are sighted eating together side by side at the cafeteria, in "Breast Cancer Show Ever", where they are cheering and watching Cartman and Wendy's fight together, in "Bebe's Boobs Destroy Society", where Clyde hugged Craig in reuniting their friendship once again, and in "Lice Capades", where Craig was the one who instructed Clyde to bring a bar of soap and a sock to beat Kenny up. Because of this, fans have sighted them as best friends like Stan and Kyle.Their names are sometimes mixed up as shown in "Super Fun Time" and they have nearly identical nasally voices. This was also noted in "South Park: The Stick of Truth" when after you talk to Craig after he replaces Clyde as the owner of the armory, he will say he was given that role because the Grand Wizard (Cartman) said he sounds like Clyde, he denies that however.
In The Stick of Truth, Craig joins Clyde's Army of Darkness as his second-in-command.
Kyle BroflovskiClyde and Kyle get along well normally. In "The List" when Clyde had been voted the cutest boy in class (the list turned out to be faked) and Kyle had been voted the ugliest, Clyde still tried to comfort Kyle - even though he was being a bit condescending at the time. However, Kyle did hurl abuse at Clyde during their sledding competition in "Cartman's Silly Hate Crime 2000" for being fat, although since he was replacing Cartman at the time, this was to be expected.
Eric CartmanClyde usually shows little or no interest in the antics of Cartman. He does join in from time to time, usually as a result of everyone else joining in as well - such as his leprechaun hunt in "Imaginationland" or his membership of the superhero group Coon and Friends. There was one occasion when Clyde vehemently stood up for Cartman when Kyle and Stan failed to believe him in "Marjorine", which shocked everyone present.
There are other times, though, when Clyde will be distracted from Cartman's schemes - when most of the 4th grade had been recruited to help take down Jenkins on World of Warcraft in "Make Love, Not Warcraft", Clyde was more interested in a Playboy magazine. He worked for Cartman in "Crack Baby Athletic Association".
Bebe StevensIn the episode "Clubhouses" Bebe has to break the news to Kyle that they can only be friends and then Bebe says "Okay, let's go Clyde." Bebe also uses the corrupted list in "The List" to make Clyde popular, so that she (and other girls) can go out with him and justify getting free shoes from the shoe store that Clyde's dad owns at the South Park Mall.

Clyde was originally used as a background character, with no other role aside from occasional lines. In Season Four, he was given a lasting personality and gradually became one of the primary members of the boys' class in Season Six and onward.

Let's Go Tower Defense Play!
Clyde plays a small role in the storyline of South Park Let's Go Tower Defense Play! and appears at the end of the "Sixth Graders' Hangout" level to inform the player that Tuong Lu Kim is looking for them to help protect his City Wall and defeat the villains. They ask him to help but he tells them he doesn't care. In gameplay, he is of the same class as Stan Marsh, Butters Stotch and Jimmy Valmer, doing average damage, speed and range, and his special ability involves tossing his colostomy bag out and causing damage to enemies within a small radius.
The Stick Of Truth
Clyde appears in South Park: The Stick of Truth as the secondary antagonist of the game.
Clyde first appears as a member of the Kingdom of Kupa Keep as a warrior under the rule of Eric Cartman. Clyde is the first person that fights with the player to learn the battle mechanics. After the elves invade the kingdom, Clyde informs that they have taken the stick, which he was supposed to guard. As result of this, Cartman banishes him "from space and time", preventing him from keep playing with them, and he angrily leaves.
Clyde is not seen again until the end of the battle of humans against elves. After they discover the Stick wasn't at the school, they find a message that leads them to Clyde's locker, where they find a laptop that is in a videocall with him. Clyde reveals that he is in possession of the Stick and has formed a new army to get revenge at his friends for kicking him out of the game. Clyde also reveals that he has a barrel containing green goo, which he uses to turn animals into Nazi Zombies soldiers. The boys go to his house but their attack fails as they are outnumbered and all the boys are sent to their houses.
After Cartman's army has greatly grown in number, they launch an assault to Clyde's fortress. When they get to his throne room, Clyde uses the goo to revive Chef as a Nazi Zombie. After he is defeated, Clyde surrenders and gives Cartman the Stick, who kicks him off the treehouse to the ground.
Clyde's personality in the game is one of a power-hungry dark lord after he is banished by Cartman. He is also apparently not very discerning when it comes to the use of the green goo. While he is effective in using it to create a Nazi Zombie army, he firmly believes the Government's cover story that it is Taco Bell green sauce, and attributes its strange properties to its ingredients.
