List of breakout characters

A breakout character is a character in serial fiction, especially a member of an ensemble cast, who becomes much more prominent, popular, discussed, or imitated than expected by the creators. A breakout character may equal or overtake the other characters in popularity, including the protagonist. Prominent breakout characters will often make cameo appearances in expanded franchises or feature as main characters in spin-off installments of their own.

Animation

Character	Introduced in Animated Series	Year Introduced	Notes
Porky Pig	Looney Tunes (1930–present); Merrie Melodies (1931–present)	1935	Porky Pig (first voiced by Joe Dougherty, shortly thereafter replaced by Mel Blanc) debuted as a supporting character in an ensemble cast of new characters that included, among others, Beans the Cat. Only a year later, it became clear that audiences were more interested in Beans' stuttering sidekick, Porky Pig. After Westward Whoa, Beans and the others were phased out and Porky replaced him as the star of Looney Tunes. Looney Tunes itself was designed to be a showcase of music from the music publishers' record companies that Warner Bros. owned. By 1935, the show was overhauled to accommodate Porky Pig after the character increased in prominence. Porky Pig's popularity was also instrumental in facilitating the success of Looney Tunes merchandise for the next several decades.
Bugs Bunny	Looney Tunes (1930–present); Merrie Melodies (1931–present)	1938	Bugs Bunny (first voiced by Mel Blanc) was originally envisioned as one of several potential foils for Porky Pig, alongside unsuccessful competitors including Gabby Goat and Petunia Pig. While Daffy Duck, who himself became a substantial star for Warner Bros., won that role, Bugs developed as a character in his own right by 1940 and became the biggest star in the Looney Tunes and Merrie Melodies shorts, developing his own cast of foils and starring in shorts for Warner Bros. until 1964. TV Guide identified Bugs as the greatest cartoon character in history in a 2002 listicle.
Woody Woodpecker	Woody Woodpecker (1940–present)	1940	Woody Woodpecker began as an unnamed minor character in Knock Knock, a short film featuring Andy Panda who was then Universal's star character. Audiences liked him immediately, so he became the star of his own cartoons.
Yogi Bear	The Huckleberry Hound Show (1958–1961)	1958	Yogi Bear (first voiced by Daws Butler) debuted in 1958 as a supporting character in one of three segments of The Huckleberry Hound Show. Yogi Bear's segment of the show became extremely popular and over time, overshadowed its titular character Huckleberry Hound in popularity. The first breakout character in animated television created by Hanna Barbera, Yogi Bear began starring in his own show by 1961, with Hokey Wolf taking his place on The Huckleberry Hound Show.
Bullwinkle J. Moose	Rocky and His Friends (1959–1964)	1959	Bullwinkle J. Moose (voiced by Bill Scott) on Rocky and His Friends. Although the series was originally named for Rocky the Flying Squirrel, Rocky's dim-witted sidekick Bullwinkle got most of the jokes while Rocky served as straight man. By 1961, the series had been renamed The Bullwinkle Show, a title that appears for the last three seasons of the series.
The California Raisins	Sun-Maid commercials	1986	The California Raisins (lead singer voiced by Buddy Miles) were the creation of claymation artist Will Vinton, as a work-for-hire for an advertising agency who had the California Raisin Advisory Board as its client. In light of focus group data that showed raisins were uncool, they purposely created the California Raisins as energetic soul musicians. The Raisins unexpectedly became major pop culture icons of the late 1980s, with an appearance in the television specials Will Vinton's Claymation Christmas Celebration and Meet the Raisins! along with a 13-episode traditionally animated Saturday morning cartoon, The California Raisin Show. The success of the campaign triggered a vicious cycle in which the profits from the campaign were fed back to the Board, who sent that money back to the advertising agency for more ads, leading to a member revolt and the collapse of the Board in 1994.
Harley Quinn	Batman: The Animated Series (1992–1995)	1992	Harley Quinn (first voiced by Arleen Sorkin). She first appeared in Batman: The Animated Series in the 1992 episode "Joker's Favor" in what was originally supposed to be the animated equivalent of a walk-on role. She eventually became popular enough to become one of the most common recurring villains in the series, start appearing in the comics, earn a starring role in the 2016 film Suicide Squad and even receive her own animated series in 2019.
Broly	Dragon Ball Z (1989–1996; films only)	1993	Broly is considered to be one of the most popular villains in the Dragon Ball series with a cult following, in spite of his origin as a non-canon character exclusive to the Dragon Ball animated film series as well as manga side stories. His popularity led to a rebooted canonical version of him starring in Dragon Ball Super: Broly.
Butters Stotch	South Park (1997–present)	1997	Butters Stotch (Matt Stone) on South Park. Originally a background character in the show's pilot, the character eventually emerged as a submissive foil or victim of Eric Cartman's, and gradually became one of the show's most prominent characters, sometimes as the protagonist whose schemes drive the plots of episodes, as in "Franchise Prequel", or the character whose closing soliloquy provides the philosophical insight or "moment of clarity" that serves as the episode's thematic resolution, as in "Raisins", "Cartman Sucks", and "Butterballs".
Stewie Griffin	Family Guy (1999–2003, 2005–present)	1999	Stewie Griffin (voiced by Seth MacFarlane) on Family Guy. Creator Seth MacFarlane stated that he was very surprised that Stewie turned out to be the show's breakout character, and that this required him to write stories centering on him.
Bender	Futurama (1999–2003, 2007–2013, 2023–present)	1999	Bender Bending Rodríguez (voiced by John DiMaggio) on Futurama. Bender is largely considered the show's breakout character with DiMaggio's vocal performance being credited with helping boost Futurama's longevity and loyal fan base.
X-23	X-Men: Evolution (2000–2003)	2002	X-23 first appeared in the self-titled tenth episode of the third season of the animated television series X-Men: Evolution, and is a clone and later adoptive daughter of Wolverine. X-Men: Evolution ended six episodes after X-23's second appearance, but she quickly developed a following and later made her first comic book appearance in the NYX comic series in 2004, followed by multiple comic book and video game appearances. In 2015, the character succeeded the original Wolverine and adopted his name and costume in the series All-New Wolverine. Actress Dafne Keen portrayed X-23 in the 2017 film Logan and reprised her role in Deadpool & Wolverine.

Literature

Character	Introduced in Book	Year Introduced	Notes
Sam Weller	The Pickwick Papers (1836)	1836	Sam Weller is considered to be the character that made Charles Dickens famous. The serialised episodes of The Pickwick Papers sold modestly until Weller's first appearance in the fourth episode, at which point sales exploded. The character's popularity overshadowed that of the title character Samuel Pickwick, inspiring merchandise and a dedicated stage play (Samuel Weller, or, The Pickwickians). The Paris Review stated, "arguably the most historic bump in English publishing is the Sam Weller Bump."
Ramona Quimby	Henry Huggins	1950	Ramona Quimby was introduced as a minor character, initially the two-year-old sister of elementary school student Beezus Quimby, who in turn was a friend of the titular character of Henry Huggins in the works of author Beverly Cleary. Ramona quickly became the focal point of Cleary's subsequent books, particularly with 1968's Ramona the Pest. By the time of the fourteenth and final book in the Quimby/Huggins fictional universe, 1999's Ramona's World, Ramona has aged to ten years old.

Comics

Character	Introduced in Comic(s)	Year Introduced	Notes
Krazy Kat	The Dingbat Family (1910–1916)	1910	Krazy Kat evolved from an earlier comic strip of series artist George Herriman's, The Dingbat Family, which started in 1910 and was later renamed The Family Upstairs. This comic chronicled the Dingbats' attempts to avoid the mischief of the mysterious unseen family living in the apartment above theirs and to unmask that family. Herriman would complete the cartoons about the Dingbats, and finding himself with time left over in his 8-hour work day, filled the bottom of the strip with slapstick drawings of the upstairs family's mouse preying upon the Dingbats' cat. This "basement strip" became a daily comic strip with a title (running vertically down the side of the page) in 1913 and a black and white full-page Sunday cartoon three years later. Due to the objections of editors, who considered it unsuitable for the comics sections, Krazy Kat originally appeared in the Hearst papers' art and drama sections. Hearst himself, however, enjoyed the strip so much that he gave Herriman a lifetime contract and guaranteed the cartoonist complete creative freedom.
Popeye	Thimble Theatre (1919–present)	1929	Popeye first appeared 10 years into the run of Thimble Theatre, a comic strip started in 1919 by E.C. "Elzie" Segar for the King Features Syndicate. During its first decade, the strip centered on the serialized escapades of ambitious, short-sighted entrepreneur Castor Oyl, his younger sister Olive Oyl and her boyfriend Ham Gravy. Segar introduced Popeye as a sailor hired by Castor and Ham to facilitate a single adventure. When the character disappeared from the strip afterwards, fans demanded his return, elevating him to a regular character by the end of 1929. As Popeye's prominence increased, Olive was recast as his girlfriend (facilitating Ham Gravy's disappearance in mid-1930), while Castor, initially retained as a lead character alongside Popeye, was relegated to tertiary status by the end of 1931, by which stage the strip's title was modified to Thimble Theater, Starring Popeye in response to the sailor's ascendent popularity.
Nancy	Fritzi Ritz (1922–1968)	1933	Nancy was introduced in 1933 in the comic strip Fritzi Ritz, which had debuted 11 years prior. Nancy soon emerged as a star in her own right, getting her own strip in 1938, while Fritzi Ritz's last strip would appear in 1968, becoming a supporting character in Nancy from then onward.
Snuffy Smith	Take Barney Google, F'rinstance (1919–present; now Barney Google and Snuffy Smith)	1934	Snuffy Smith was introduced as a supporting character in 1934 to Take Barney Google, F'rinstance. He became so popular that he took over the comic strip as the main character of what is now titled Barney Google and Snuffy Smith.
Nero	The Adventures of Nero (1947–2002)	1947	Nero from The Adventures of Nero by Marc Sleen was originally introduced as a side character in the series De Avonturen van Detective Van Zwam, where Detective Van Zwam was the main protagonist. From the first Van Zwam story on, Het Geheim van Matsuoka ("Matsuoka's Secret") (1947) readers reacted more enthusiastically to the dumb, lazy, vain and stubborn character Nero than the more noble and clever Van Zwam. So, from "De Hoed van Geeraard de Duivel" ("The Hat Of Gerard the Devil" (1950)) onward the series was named after Nero instead.
Scrooge McDuck	Four Color Comics (1939–1962)	1947	Scrooge McDuck was originally intended as a one-off antagonistic supporting character in Christmas on Bear Mountain, a 1947 Donald Duck story by Carl Barks, first published in Four Color Comics #178. Scrooge McDuck's popularity grew so large that he spawned an entire mythology around the character, including new supporting characters, adventures, and life experiences as told by numerous authors. In 1952 he was given his own comic book series, Uncle Scrooge, which is still ongoing today. Several stories written by Barks and published in Uncle Scrooge were adapted as episodes of the popular syndicated television cartoon DuckTales in the late 1980s.
The Smurfs	Johan and Peewit (1952–2001)	1958	The Smurfs were originally supporting characters in Peyo's comic series Johan and Peewit in 1958. The popularity of the little blue men led to them getting their own series a year later, which was subsequently followed by massive merchandising, a television series and various other productions.
Sabrina the Teenage Witch	Archie's Madhouse (1959–1982)	1962	Sabrina the Teenage Witch was originally introduced as a one-off character in the Archie Comics universe in 1969. Unbeknownst to the original creators, Filmation was interested in the character and created a Saturday morning cartoon featuring Sabrina, helping the character become one of the most popular in the Archie Comics universe. Sabrina would get a second boost of popularity in the late 1990s with a prime time live-action Sabrina the Teenage Witch series, which starred Melissa Joan Hart in the title role.
The Punisher	The Amazing Spider-Man (1963–present)	1974	The Punisher debuted as an antagonistic character in The Amazing Spider-Man #129 (February 1974). He was a hit with readers, and started to appear on a regular basis, teaming up with both Spider-Man and other heroes throughout the 1970s and 1980s. The Punisher's popularity took the character's creator, Gerry Conway by surprise, as he had intended him only as a second-tier character. The character evolved into an anti-hero and became one of Marvel's most popular characters in the 1990s, having a starring role in multiple comic book series, television series, films, and video games. His name, symbol, and image have been used for merchandise or appropriated for discussion of social issues.
Wolverine	The Incredible Hulk (1962–present)	1974	Wolverine is frequently cited as the first breakout character from the X-Men comics series, and "arguably the breakout character of the 1980s." He debuted in 1974's The Incredible Hulk #180 as a superhuman agent of the Canadian government who comes into conflict with the Hulk. He later appeared in 1975's Giant-Size X-Men #1, during writer Chris Claremont's first run with the X-Men, as one of several new recruits of the team. Wolverine was consistently the most popular member of the team; he headlined his first limited series in 1982, and later an ongoing solo series debuted in 1988, which eventually established Wolverine as one of Marvel's most important characters.
Elektra	Daredevil (1964–present)	1981	Elektra debuted as a supporting character in Daredevil #168 (January 1981) as a love interest of the superhero Daredevil, and quickly broke out in popularity. Frank Miller, who created Elektra, secured a promise from Marvel's editors to stop using Elektra after he had concluded her storyline. Marvel abided by this agreement until the mid-1990s, when later editors and ownership groups decided to revive the character against Miller's wishes. The character remains one of Marvel's most popular female characters, with a starring role in two eponymous ongoing series, several mini-series, an eponymous live action film in 2005, as well as a major role in the 2003 film Daredevil and Marvel's Netflix television series.
Opus the Penguin	Bloom County (1980–1989, 2015–present)	1981	Opus the Penguin, of Bloom County, Outland, and Opus, was originally featured in a two-week narrative in Bloom County in 1981. Fans requested more appearances of the penguin and series creator Berkeley Breathed was pleased with how well the character integrated with other characters in the strip. Opus was made a permanent character, displacing the original cast as the focus of the strip and its sequels. Another Berkeley Breathed creation, Bill the Cat, is also cited as a throwaway character which turned into a breakout success.
Venom	The Amazing Spider-Man (1963–present)	1984	Venom was originally introduced as a living alien costume in The Amazing Spider-Man #252 (May 1984). The creature made its full first appearance with Eddie Brock as its host in The Amazing Spider-Man #300 (May 1988). Venom's popularity in the late 1980s and early 1990s inspired a series of symbiote characters published by Marvel comics, and the character eventually transitioned from a villain to an anti-hero, appearing as a principal character in a number of comic book series. The character has also appeared in numerous other media, including an eponymous live action film in 2018.
John Constantine	The Saga of Swamp Thing (1982–1999)	1985	John Constantine debuted as a supporting character who played a pivotal role in the "American Gothic" Swamp Thing storyline in 1985. Constantine was an instant breakout character, and received his own ongoing solo comic series in 1988. The Hellblazer series was the longest-running and most successful title of DC's Vertigo imprint. The character was adapted for a live-action film, a television show, novels, and multiple spin-offs and crossovers.
Vegeta	Dragon Ball (1984–present)	1988	Vegeta debuted as a villain in Dragon Ball chapter #204 Sayonara, Son Goku (さようなら孫悟空, Sayōnara Son Gokū), in Weekly Shōnen Jump magazine on November 7, 1988. Vegeta's popularity among fans in Japan led to Dragon Ball's author, Akira Toriyama, to forgo his initial plan for Vegeta as a short lived villain. Toriyama included him more in the story, and Vegeta became one of Dragon Ball's most prominent characters.
Death (DC Comics)	The Sandman (1989–present)	1989	Death (DC Comics) debuted in 1989 as a supporting character in Neil Gaiman's The Sandman. She is considered the breakout character of the entire Sandman series by multiple sources.
Deadpool	The New Mutants (1982–present)	1991	Deadpool debuted as a villain in The New Mutants #98 (February 1991), and subsequently made guest appearances in issues of X-Force. The character's popularity led to the publication of his first solo comic, the four-issue limited series Deadpool: The Circle Chase on August 10, 1993. He is notable as one of the few breakout comic characters in the 1990s and 2000s, having a starring role in multiple comic series, a 2013 video game, and two live action eponymous films in 2016 and 2018.
Hit-Girl	Kick-Ass: The Dave Lizewski Years (2008-2014)	2008	Hit-Girl is a breakout character from the Kick-Ass: The Dave Lizewski Years who went on to have her own comic book series.
Spider-Gwen	Edge of Spider-Verse (2014–2015)	2014	An alternative universe version of Gwen Stacy, commonly referred to as Spider-Gwen, first appears in Edge of Spider-Verse #2 (September 2014) as part of the 2014–15 "Spider-Verse" comic book storyline, which features multiple alternative versions of Spider-Man that had appeared in various media. The character subsequently became one of comics' biggest breakout characters in recent years; the character is the lead heroine in her own ongoing comic book series, numerous animated television and video game appearances, as well as a co-starring role in the Academy Award-winning Spider-Man: Into the Spider-Verse. The character also inspired the creation of twenty Marvel variant covers of Gwen Stacy reimagined as a wide array of Marvel heroes in June 2015, spawning popular hybrid variants such as Gwenpool, a variant of Deadpool.
Doctor Aphra	Star Wars: Darth Vader (2015–2016, 2016; 2017–2018; 2020–present)	2015	Doctor Aphra debuted as a supporting character in the 2015 Marvel Comics series Star Wars: Darth Vader, her popularity as a breakout character leading to crossovers in other comics, and then her own series, Doctor Aphra. Aphra is the first original Star Wars character not from the films to lead a Marvel comic series.

Film

Characters	Introduced in Film or Film Series	Year Introduced	Notes
Inspector Jacques Clouseau	The Pink Panther (1963–present)	1963	Inspector Jacques Clouseau, Peter Sellers' character in the Pink Panther film series, was originally conceived as a supporting character to David Niven's gentleman burglar Sir Charles Lytton in the film that launched the franchise, but quickly became the protagonist.
Boba Fett	Star Wars (1977–present)	1978	Boba Fett was introduced in the 1978 Star Wars Holiday Special, before appearing in supporting roles in The Empire Strikes Back and Return of the Jedi. Though his screen time in the original Star Wars trilogy was minimal, and he apparently died an ignominious death in the third film, his visual design made him an iconic mainstay of the franchise. In the original Star Wars Expanded Universe, more commonly referred to as Star Wars: Legends, his character was established to have survived in the 1991 comics series Dark Empire. He also became a recurring character in Star Wars video games, including Bounty Hunter and the Battlefront series. His backstory would be provided in the 1999 – 2005 prequel trilogy, which gave rise to other Mandalorian characters, including Din Djarin in the television series The Mandalorian. Fett himself reappeared in that series, making his survival from the events of Jedi canonical.
Puss in Boots	Shrek (2001–present)	2004	Puss in Boots (voiced by Antonio Banderas), based on the fairy tale character of the same name, first appeared in the 2004 film Shrek 2. The character's popularity would go on to spawn two spin-off films, Puss in Boots (2011) and The Last Wish (2022), alongside the animated series The Adventures of Puss in Boots (2015-2018).
Tow Mater	Cars (2006–present)	2006	Tow Mater (voiced by Larry the Cable Guy) debuted in Cars (2006), the first animated film in the Disney/Pixar Cars franchise as a supporting character and best friend to series protagonist Lightning McQueen. Being the breakout character of the film, he was given a prominent role in the Cars franchise. His lead role in Cars 2 was criticised by critics for stealing the spotlight from Lightning McQueen, while his character was likened to the Star Wars character Jar Jar Binks.
Aldous Snow	Forgetting Sarah Marshall (2008)	2008	Aldous Snow, Russell Brand's character in Forgetting Sarah Marshall. He later appears in a starring role in the 2010 spin-off sequel Get Him to the Greek.
Phil Coulson	Marvel Cinematic Universe (2008–present)	2008	Phil Coulson, portrayed by Clark Gregg in the Marvel Cinematic Universe, initially had a minor part in Iron Man (2008). This led to further recurring appearances in Iron Man 2 (2010), Thor (2011), and two Marvel One-Shots (2011), and The Avengers (2012) in which Coulson is murdered. The character is then revealed to be alive in the pilot episode of Agents of S.H.I.E.L.D., in which he was the main character. Other appearances included that series' digital spinoff, various tie-in comics, animated series, and Captain Marvel (2019).
The Minions	Despicable Me (2010–present)	2010	The Minions became breakout characters in the 2010 animated film Despicable Me. They eventually starred in a 2015 spinoff, Minions.
Yondu Udonta	Marvel Cinematic Universe (2008–present)	2014	Yondu Udonta, portrayed by Michael Rooker in the Marvel Cinematic Universe films Guardians of the Galaxy and Guardians of the Galaxy Vol. 2, was originally written as a supporting ally of the titular superhero team. Following the positive reception for the character in the first film, his role was upgraded significantly for the second, where he was considered by many critics to give a show-stealing performance.

Radio

Characters	Introduced on Radio Program or Series	Year Introduced	Notes
Throckmorton Philharmonic Gildersleeve	Fibber McGee & Molly (1935–1959)	1939	Throckmorton Philharmonic Gildersleeve (as portrayed by Harold Peary, later replaced by Willard Waterman in 1950) was an antagonist on the long-running radio comedy Fibber McGee & Molly around 1939. The pompous underwear salesman proved popular enough to warrant a spin-off, The Great Gildersleeve, in 1941. Like its parent show, Gildersleeve would go on to a long run in radio, film and (briefly) television; the last episode of Gildersleeve aired in 1958.

Television

Characters	Introduced in TV Show	Year Introduced	Notes
Dagmar	Broadway Open House (1950–1951)	1950	Dagmar (Virginia "Jennie" Lewis) was a character created for Broadway Open House, American television's first late-night variety show. The show had faced a challenge in that a daily television variety show had never been attempted before and would require an unprecedented amount of new material, produced quickly, which soon exhausted all of host Jerry Lester's material. The solution was to bring in Lewis, who was given no script and an instruction to improvise as a dumb blonde named Dagmar, who would serve as Lester's foil. The character became a national sensation, briefly carrying on after Lester finally left the show after a year, appearing on a cover story for Life magazine, and recording a duet with Frank Sinatra in character, "Mama Will Bark."
Maynard G. Krebs	The Many Loves of Dobie Gillis (1959–1963)	1959	Maynard G. Krebs (Bob Denver) on The Many Loves of Dobie Gillis, was originally created as a supporting character, the beatnik best friend of the titular character Dobie Gillis, when the series began in 1959. By 1960, Denver had graduated to co-lead and Maynard was given the bulk of the comedy material, with Dwayne Hickman's Dobie as the straight man. Dobie Gillis was Denver's first professional acting job, and the breakout success of the Maynard character led to Denver starring on Gilligan's Island after Dobie ended in 1963. Krebs was famously parodied as Shaggy Rogers (voiced by Casey Kasem) in the long-running Scooby-Doo franchise; Shaggy was largely an updated hippie reimagining of Krebs.
Spock	Star Trek (1966–1969)	1966	Spock (Leonard Nimoy) on Star Trek was the only character to be carried over from the original pilot to the second. Series creator Gene Roddenberry was pressured by NBC to drop the character from the second pilot, then later to keep the character in the background. Spock's popularity grew, and NBC soon reversed its stance, encouraging more focus on the character. Spock appeared in every episode of the original series, the animated series and the original cast films.
Polkaroo	Polka Dot Door (1971-1993)	1971	Initially, the Polkaroo only appeared on Thursdays on Imagination Day, normally being played in costume by the male host. Over time, the character became so popular with fans, that he made additional appearances later on in the series and in the two one hour specials. After Polka Dot Door ended, TVOntario capitalized on his success by making him be the main protagonist of Polka Dot Shorts. He also made appearances in Gisèle's Big Backyard
Super Dave Osborne	The John Byner Comedy Hour	1972 (breakout c. 1980)	Super Dave Osborne was created, written and performed by veteran variety show writer Bob Einstein as a character for John Byner's eponymous comedy hour, but would become a permanent feature of Byner's next variety show, Bizarre, where the show—based in Canada and syndicated to premium cable in the United States, allowing for more adult language than other variety shows of the day—made Osborne, a perpetually failing stuntman, a household name. After Byner ended Bizarre, the show's producers retained Einstein's services for four more years with the show Super Dave, which was followed by the animated series Super Dave: Daredevil for Hire, which required a severe toning-down of the character's language and ethnic stereotypes.
Thelma "Mama" Harper	The Carol Burnett Show (1967–1977)	1974	Thelma "Mama" Harper (Vicki Lawrence) originated in a recurring sketch on The Carol Burnett Show, The Family, as a cantankerous elderly matriarch constantly bickering with her daughter Eunice (Carol Burnett, who in real life is older than Lawrence). Mama and Eunice would go on to appear in the television film Eunice, after which Lawrence starred for several years in a standalone sitcom centered around the character, Mama's Family, which became a major hit in first-run syndication. Lawrence continues to use the Mama character in live stage appearances.
J.J. Evans	Good Times (1974-1979)	1974	J.J. Evans (Jimmie Walker) on Good Times, with his catchphrase "Dy-no-mite!", came to dominate the family series, leading to friction with stars Esther Rolle and John Amos, who played his parents. Amos and Rolle's concern was not so much that they resented being upstaged, but rather that they felt the J.J. character was too stereotypical and not a good role model for young African American viewers. A showdown with the show's producers in 1976 led to modification of the character, Amos' character being killed off and a temporary departure by Rolle from the show. Rolle returned at the beginning of the show's final season in 1978–79, and J.J. became an even stronger focus of the show.
Fonzie	Happy Days (1974–1984)	1974	Fonzie (Henry Winkler) on the American sitcom Happy Days began in a supporting role, but quickly evolved into the focal point of the series. His character became the best friend to the main character, Richie Cunningham, displacing Potsie Weber's status as such. Winkler's billing in the credits rose to second (he refused to appear above Ron Howard, the star) and then first after Howard left the show to pursue directing. At one point, network executives hoped to retitle the show Fonzie's Happy Days.
K-9	Doctor Who (1963–1989, 2005–present)	1977	K-9 (John Leeson and David Brierly) on Doctor Who, was a robotic dog who served as the Doctor's companion from 1977 to 1980. Following the character's departure, he appeared in the pilot for the aborted spin-off series K-9 and Company. He later appeared in three episodes of the revived series of Doctor Who, made appearances on the spin-off series The Sarah Jane Adventures, and was the central character in the spin-off series K-9.
J. R. Ewing	Dallas (1978–1991, 2012–2014)	1978	J. R. Ewing (Larry Hagman) on Dallas. The initial concept of Dallas was a Romeo and Juliet-esque tale, focusing on two star-crossed lovers whose families are sworn enemies, with the amoral brother J.R. serving as a supporting character. However, the popularity of both the character and Hagman grew, and the producers acknowledged his new status as the series' breakout character. Two highly rated 1980 episodes became pop culture zeniths. In "A House Divided" and "Who Done It?", the audience witnessed J.R. being shot by an unknown assailant. After the cliffhanger was broadcast in March 1980, the audience was forced to wait until the October premiere of the next season for the cliffhanger's resolution. The intervening hiatus gave rise to the "Who shot J.R.?" phenonmenon. Riding the crest of his newfound popularity, Larry Hagman threatened to leave the series unless his contractual demands were met. CBS leaked rumors of recasting, but Hagman eventually prevailed. As the series progressed, J.R. emerged as the central character until the show's cancellation in 1991, with Hagman serving as executive producer for the final few seasons. Hagman would go on to reprise the character in two television films and a revival series until his death in 2012.
Bob and Doug McKenzie	SCTV (1976–1984)	1980	Bob and Doug McKenzie (portrayed by Rick Moranis and Dave Thomas respectively) were created as Canadian content filler for SCTV, appearing as hosts of the show-within-a-show "The Great White North" and improvising as two drunken stereotypical Canadians. The duo were spun off into the film Strange Brew, an album also titled The Great White North, and several appearances in other films and television shows. Their success also led to Moranis and Thomas being forced out of the SCTV cast in 1982 due to the other cast members becoming resentful of the duo's success.
