Chuck Cunningham syndrome is a phenomenon observed when a regular character in a television series leaves with no explanation, and is never referred to again despite the character's previous importance either to the show or to the other characters. The term has been used since at least as early as 1997.

The term derives from the Chuck Cunningham character from the American series Happy Days (1974-1984). Chuck, the oldest of the three children in the Cunningham family, first appeared in the pilot episode "Love and the Happy Days" (aired as part of the series Love, American Style). However, when Happy Days became its own series, Chuck appeared as a minor character (usually seen on his way to basketball practice). He was written out of the series at the beginning of the second season with the explanation that he was going off to college. After the second season, he was never mentioned again. Subsequent episodes referred to the Cunninghams as having only two children (Richie and Joanie).

Chuck Cunningham was played by two different actors during his short run in the series (Gavan O'Herlihy and Randolph Roberts). This also makes Chuck Cunningham an example of Darrin Syndrome. The Happy Days reunion special that aired on February 3, 2005 referred to the character's disappearance and both "Chuck" actors were then brought out as a surprise for Marion Ross and the rest of the Happy Days cast.

The process has also been referred to by fans of the show ER as "being Bobbed", named after a supporting character who suffered a similar fate.

• Victor Bergman (Barry Morse) also vanished between the first and second seasons. A throwaway line about a spacesuit malfunction was written, but not aired. Morse left due to a contract dispute with Freiberger.[citation needed]
• Sandra Benes Zenia Merton disappears a few episodes into the second season without explanation, and is replaced by a Japanese character named "Yasko." Yasko herself abruptly disappears after twelve episodes without explanation, and is replaced by Benes.[citation needed]

Spin City:

• At the end of the fourth season, four principal characters departed: Mike Flaherty (Michael J. Fox), Nikki Faber (Connie Britton), James Hobert (Alexander Chaplin) and Janelle Cooper (Victoria Dillard). While Michael J. Fox's departure was set up over the course of several episodes, and he made guest appearances in later seasons, none of the other characters were ever mentioned again, and the reasons for their disappearances remain a mystery.[citation needed]
• Stacey Paterno (Jennifer Esposito) and Angie Ordonez (Lana Parilla) similarly vanished without comment at other points in the series' run.[citation needed]

SpongeBob SquarePants:

• In the pilot episode, SpongeBob has a pet scallop, Shelly, sitting by his bed. We only see him again in one more episode, and after that Shelly disappears completely, apparently replaced by Gary the snail.[citation needed]

Star Blazers:

• The chief engineer Orion who was a regular during the Quest for Iscandar and Comet Empire series was not seen in the third season, The Bolar Wars. He was replaced by another chief engineer. In the Japanese version of these series, Orion (Tokugawa) was killed near the end of the Comet Empire and his replacement, Joe Yamazaki was introduced in the movie Yamato: The New Voyage which was never released as part of the Star Blazers continuity. Orion's death was simply cut out of the English language Star Blazers.[citation needed]
• In the original Space Battleship Yamato canon, the rookie characters of Sakamoto and Kitano are introduced as apprentices to Kodai and Shima during Yamato: the New Voyage which also introduces Tasuke Tokugawa (Orion Jr.). Tasuke continues in the further Yamato movies and series but Sakamoto and Kitano are never seen again. Sakamoto's place is taken over in the following film Be Forever Yamato by Shiro Kato (Conroy), brother of the late Saburo Kato (Conroy).[citation needed]

Star Trek: The Next Generation:

• Commander Katherine Pulaski, MD replaces Dr. Beverley Crusher for the second season. In the third season Crusher returns and there's no sign of Pulaski.

Stargate SG-1:

• Dr. Carolyn Lam, daughter of Gen. Landry, was a recurring character meant to replace the late Dr. Janet Fraiser as the SGC's chief medical officer. However, she has not appeared since the plague outbreak in The Fourth Horseman although she was mentioned in dialogue as late as Morpheus. Her absence may be largely due to actress Lexa Doig's real life pregnancy.[8]

Stargate Atlantis:

• Sgt. Bates, a frequent foil of Sheppard and Teyla in Season One, is not seen at all in subsequent seasons.[citation needed]

Step By Step:

• In the first season, Carol owns a beauty salon attached to the Lamberts' house. The beauty salon employs two women, Carol's mother and sister, who are also main characters. After the first season, the two women are completely dropped.[citation needed]
• The youngest Lambert boy on the show, Brendan, saw his role reduced during the last few years of the show (especially after the birth of Lilly) until he was completely dropped from the show during the last season without explanation.[citation needed]

Teachers (UK)

• Susan, Jenny and JP; three regular characters with significant roles in the show, disappeared in between series 2 and 3 with no explanation. Brian, Kurt and Matt also disappear in between series 3 and 4, though it's implied they died in a car crash.

Taxi:

• Cabbie John Burns (Randall Carver), a displaced midwesterner, disappeared after one season of being a regular character. Nothing was mentioned about it on the show, but the producers realized the character had run its course, and most jokes associated with his character could easily be transferred to Tony Banta (Tony Danza).[citation needed]

That's My Mama:

• Two old fellows who frequented Clifton's Barbershop, Wildcat (Jester Hairston) and Josh (DeForest Convan) disappeared after the first season, and were never mentioned again.[citation needed]

That's So Raven:

• Mr. Lawler appeared throughout season one and in one episode from Season two, and was never seen or heard from again.[citation needed]

The Thin Blue Line:

• While only two series of this sitcom were made in the mid 1990s, there were two cases of Chuck Cunningham Syndrome, with the characters of DC Kray (Kevin Allen) & DC Crocket (Joy Brook) leaving without explanation. No mention was ever made of these characters again.[citation needed]

Three's Company:

• Next-door neighbor Lana Shields (Ann Wedgeworth) was added to the show at the beginning of the fourth season but disappeared without explanation after only a handful of episodes when the show's writers realized they had run out of ideas for her.[citation needed]

The Tomorrow People:

• During the 1990s version of The Tomorrow People, the show originally introduced Adam Newman, Lisa Davies, and Kevin Wilson as the shows three main characters with the ability to "teleport". Marmaduke 'Megabyte' Damon was originally a close friend of Kevin's with no teleportation ability. However as the shows later stories were broadcasted, both Lisa and Kevin disappeared and only Adam and Megabyte (now with teleportation abilities) remained steady as the shows main characters.[citation needed]

The Torkelsons:

• During their move from Oklahoma to Seattle (and the show's name change to Almost Home), the family mysteriously lost two children, Steven Floyd and Ruth Ann.[citation needed]

UFO:

• At the mid-point of this cult science fiction series' first and only season, several major cast members drop out without explanation, most notably the character of Col. Alec Freeman (George Sewell) who is replaced as the first officer of the secret organization SHADO by Col. Virginia Lake (Wanda Ventham). (The dropping of several characters was sparked by a five-month break in production while the series changed studios, during which time several lead actors took roles in other shows and were thus unable to return.)[citation needed]

The West Wing:

• The character Mandy Hampton was featured in the shows first season as White House media consultant. She is never mentioned or seen again after the season finale, and no explanation was ever given for her departure, although writer Aaron Sorkin mentions in an official West Wing book that her character "wasn't working" and that her departure was amicable.[citation needed]

The term "Mandyville" was named after her sudden disappearance. On the website Television Without Pity, Mandyville is the place fans of The West Wing on the site say where she disappeared to.

Yu-Gi-Oh!/Yu-Gi-Oh! GX

• Bastion Misawa inexplicably disappears from the cast after episode 97, and had not reappeared or mentioned until episode 120. It was later explained that he had joined Society of Light member Albert Zweinstein in one of his experiments, and was transported to the Duel Monsters world, the rest of the cast eventually ends up in Season 3, but there's still no explanation as to how no one noticed he was missing (especially Jaden, who had a sort of rivalry going on with Bastion and, thus, was the closest to him friendship-wise).
• Similarly, "Bandit" Keith Howard vanishes after his last duel with Yugi during the beginning of the Battle City arc, and is only mentioned within the context of that duel a few more times later in the arc. This is most likely due to the fact that Bandit Keith was killed in the manga during Duelist Kingdom and the Battle City duel never took place.
• Zane Truesdale leaves the cast permanently near the end of Season 2, and is not mentioned or seen until episode 128, where he unceremoniously duels Johan Andersen. This is a unique case, as while his reasons for leaving is clear (he has turned pro and, thus, has no use for hanging around his former friends), the reasons behind his lack of reference is not; a minor subplot in season 2 was for his friends trying to snap him out of his overly aggressive mentality on dueling, and while they failed in that endeavor, there was no indication that they were going to give up, making their non-mentioning of Zane or their attempts to turn him around very Cunningham-esque.
• Finally, Atticus Rhodes is missing completely from season 3, with no mention as to what happened to him.

Home Alone:

• In the first two installments, Kevin McAllister (Macaulay Culkin) has two brothers (Buzz and Jeff) and two sisters (Megan and Lainie). The third film focused on another family. When the franchise returned to the (recast) McAllisters in Home Alone 4, Buzz and Megan are his only siblings; one of many cases in which the film significantly deviated from established series continuity.[citation needed]

The Simpsons Movie:

• Homer's pet pig Plopper/Spiderpig is last seen in the Simpsons household. After the Simpsons flee their house after being chased by an angry mob, he is never seen or mentioned again from that point on. He was last seen shortly before the house caught on fire. He has however been seen in episodes produced after the movie.

Dr. Dolittle film series:

• The character Charisse (played by Raven Symone) was a main character in the first two movies. She had her father's ability to talk to animals as well, as her younger sister Maya didn't. By the third movie, the character is missing, and is still mentioned yet nowhere to be found. By the fourth and fifth movies, she is still not seen.

I Know What You Did Last Summer

• In I Know What You Did Last Summer Barry Cox, played by Ryan Phillippe, is the main character who meets his demise along with another main character. In the sequal I Still Know What You Did Last Summer he is never mentioned even when Freddie Prinze Jr. character is referring to what occured last summer he mentions all of the characters even the deceased apart from Barry.

The Santa Clause film series:

• The head-elf Bernard is a main character in the first two movies, but because of David Krumholtz (actor) work issues in his new TV Show Numb3rs, the character Bernard was completely dropped from the series by the third film in which the character is not seen or mentioned at all.

Poltergeist film series:

• The oldest daughter Dana Freeling (Dominique Dunne) was only seen in the first film. Dominique Dunne died on November 4th 1982, her ex-boyfriend was convicted of her manslaughter. As a result, no further reference was made to her character in the Poltergeist films.[citation needed]

Problem Child:

• In Problem Child 2 Ben Healey (John Ritter) met and fell in love with Annie Young (Amy Yasbeck), who had a daughter named Trixie. The conclusion of Problem Child 2 suggested a "happily ever after" ending. However, in Problem Child 3, Ben and Junior are alone: There is no trace of Annie or Trixie, and no explanation as to what happened to them.[citation needed]

Return to Mayberry:

• In the TV series Mayberry R. F. D., Andy Taylor and Helen Crump marry in the first episode in September 1968 and one year later they come back to Mayberry with a baby son, Andy, Jr. They did an episode with four prospective godfathers (Howard, Emmett, Goober, and Sam) battling over the baby. You never know if they had any other children, but in the reunion movie from 1986, in which Andy, Jr. should have been 17, his existence was never mentioned.

Transformers: The Movie:

• In one scene, Bombshell and Skywarp are transformed into "Cyclonus and his armada"; and Thundercracker, Kickback, and Shrapnel, are transformed into "Scourge and the Sweeps". In the scene immediately following, however, the "armada", (in actuality, only one ship, Skywarp's altered form), is gone and never seen or mentioned again, and there are suddenly three sweeps present, not two.[citation needed]

Blade:

• The character of Doctor Karen Jenson (N'Bushe Wright) played a pivotal role in the film as a hematologist who not only developed a cure for vampirism and improved the serum used by Blade to steer away the "thirst" for human blood, but also discovers that EDTA (a blood thinner normally used clear clots) has a highly volatile reaction to vampire blood, which becomes essential to the movie's plot. In the sequels, Blade II and Blade Trinity, no mention of Jenson or her contributions to the Blade universe are ever mentioned again.[citation needed]

General Movie Franchises:

• Sequels often do not contain appearances by or reference earlier characters due to actors not reprising roles or a purposeful distancing from earlier entries. A love interest like Chase Meridian in Batman Forever may be significant at the time but doesn't get a mention in Batman & Robin and her predecessor Vicky Vale only does marginally better with a non-specific reference in Batman Returns.

James Bond:

• In every EON production movie up to the penultimate pre-reboot movie The World is Not Enough - except for On Her Majesty's Secret Service - Bond ends up with his love interest. At the start of the next movie she's gone and never mentioned again.
• Sylvia Trench, Bond's regular girlfriend in Dr. No, and From Russia with Love disappears after that.
• Sir Frederick Gray, The Minister of Defence in six movies disappears after The Living Daylights.

Police Academy:

• Not a single character that departed before the final movie was written out or referred to again.

Johnny English:

• Bough and Lorna Campbell were Johnny's sidekicks in the first movie. Neither were seen or mentioned in Reborn.

Charlie's Angels:

• In the original Dylan has a boyfriend, Chad. In Full Throttle we learn that Seamus O'Grady, the movie villain, is an old flame, but no sign or mention of Chad.

Superman:

• In the third installment Clark's love interest is Lana Lang, a returning childhood friend from Smallville. Yet in The Quest for Peace his attentions return to Lois Lane, with no sign or reference to Lang.

Mission: Impossible:

• In the second movie Hunt's love interest is Nyah Nordoff-Hall. Much in the same vein as the Bond movies, she gone and forgotten by the sequel.

City Slickers:

• In the original Ed Furillo was part of the trio of New Yorkers. In The Legend Of Curly's Gold he's replaced by Mitch Robbins' brother, Glenn. No sign of Furiilo.

Meet the Parents:

• Jack Byrnes' had a son, Denny, in the first movie, he wasn't seen nor mentioned in the two sequels. In Little Fockers, Jack asked Greg to be "The Godfocker", suggesting he had no male heir.

Calvin and Hobbes:

• Calvin had an Uncle Max. After a week, creator, Bill Watterson felt Max didn’t create enough humor for Calvin to play off of. Also, Calvin’s parents were not given first names; Watterson felt it would be odd that Max calls them only by pet names (like “bro”)![citation needed]

Peanuts:

• The "Great Missing" character of Charlotte Braun was seen in a handful of strips. Intended to be a major character she was written out when creator Charles Schulz realized her one main characteristic (she was loud) was covered already and much better by Lucy.
• Another character, Frieda's cat Faron, was introduced by Schulz as a rival to Snoopy. Schultz discontinued the character when he felt Snoopy's reactions toward the cat made Snoopy appear too much like an actual dog.

Garfield:

• The character of Lyman, Odie's owner, was dropped after the first few years of the comic strip, and Odie suddenly became Jon's pet. Cartoonist Jim Davis explained that the character of Lyman was created to give Garfield's owner, Jon, someone to talk to. As Garfield's character evolved into a more human-like persona, Jon's conversations became more centered around Garfield, making Lyman superfluous. While the strip doesn't explain Lyman's sudden disappearance, Jim Davis's humorous explanation was, "don't look in Jon's basement!".[citation needed] He also gives some humorous scenarios as to what happened to Lyman in the Garfield 20th Anniversary Book. On the official Garfield site, in the Scary Scavenger Hunt game, Lyman appears chained to the wall in the mansion's dungeon.

Dominic Deegan: Oracle For Hire:

• The first time the unnamed Infernomancer appears [9], he is accompanied by a berserker named Brok. The Infernomancer and Brok then fight against the main characters for the life of a dryad. Partway through the battle, Brok chases away the supporting characters Stunt and Bumper. [10] Brok never reappears and is only mentioned once in passing after this point; the battle is resolved without his presence, Stunt and Bumper never mention the outcome of that chase, and the Infernomancer works alone in every subsequent appearance. The comic's FAQ page states that the character of Brok was scrapped.

• In the first movie, The Bears consist of the characters Amanda Whurlitzer, Kelly Leak, Tanner Boyle, Ahmad Abdul Rahim, Alfred Ogilvie, Mike Engleberg, Rudi Stein, Timmy Loupus, Jimmy Feldman, Toby Whitewood, Miguel and Jose Aguilar, and Regi Tower, by the second movie, it was reduced to Kelly, Tanner, Ahmad, Ogilivie, Engleberg, Rudi, Timmy, Jimmy, Toby, and Jose and Miguel, Regi and Amanda just disapeared without an explanation of where they went. Then it got really bad in the third (and final) movie in which Ogilvy, Tanner, Timmy, Carmen Ronzonni (character introduced in the second movie), and Jose Aguilar all disapeared without explanation.

Banjo-Kazooie Series

• Banjo's sister, Tooty vanishes in Banjo-Tooie and also doesn't appear in any other Banjo games released after Banjo-Kazooie. No explanation was given of her absence, and she is never mentioned by any of the characters.

Ratchet and Clank:

• In the Second game of the series, Ratchet & Clank: Going Commando, Ratchet seemingly ends up linked romanticly to Angela Cross, but by the third game Ratchet & Clank: Up Your Arsenal, Angela is gone and is never mentioned, even as Ratchet falls for Captain Sasha.[citation needed]

Sonic the Hedgehog series:

• Many early Sonic characters have disappeared with little to no explanation: Mighty the Armadillo, who had appeared in two games (SegaSonic the Hedgehog and Knuckles Chaotix) has vanished without a trace, with only the vague explanation that he was a traveler given to mask his departure; similarly, Ray the Squirrel (also from SegaSonic the Hedgehog) hasn't been mentioned since his only appearance. Fang the Sniper has also disappeared after his last performance in Sonic the Fighters. Many other minor characters and locales (like Heavy and Bomb from Knuckles Chaotix, Bean the Dynamite and Bark the Polar Bear from Sonic Fighters, and Little Planet from Sonic CD) are never mentioned or seen outside of their initial appearance.

Mega Man X series:

• Dr. Cain mysteriously disappears as a character after Mega Man X2, and is never mentioned after X4, with no explination as to why he left. The recent remake of the original Mega Man X, Maverick Hunter X, has Cain in poorer health than he was in the original games, with him dying at the end of the game, but it's uncertain if the revised continuity of the game will continue.
• Similarly, the minor villain Dynamo disappeared after Mega Man X6.

Spyro the Dragon series:

• Bianca the Rabbit, a minor villain-turned-heroine in Spyro 3: Year of the Dragon, becomes a love interest to Spyro ally Hunter near the end of the game, but is not seen or heard from in later installments.

Mortal Kombat series:

• In Mortal Kombat Mythologies: Sub-Zero, three other elemental gods are seen alongside Fujin in the Temple of Elements stages, but while it's confirmed Fujin survived the ordeal and went on to appear in future games, the fate of these other three gods have been overlooked.
• The prequel game Mortal Kombat: Special Forces introduced the Black Dragon members No-Face, Tasia, and Tremor, but their fate after this game has never been clarified. Also, in a unique version of 'reverse Cunningham Syndrome', Kabal was not seen or mentioned in the game in any capacity.

A reverse Cunningham is essentially the opposite of Chuck Cunningham syndrome, in which a previously-unknown and un-alluded-to character is introduced under the context that they had always been there, and had significantly interacted with the other characters before. This causes even more continuity problems than regular Cunningham Syndrome, as although it's easy to overlook the sudden absence of a character, it's harder to ignore the sudden appearance of a character, especially one that we are expected to believe was part of the regular cast, all along. Perhaps because it creates even more credibility problems, producers are much less likely to suddenly introduce characters whose presence should have been at least alluded to or explained earlier. But it has happened on a few occasions.

Are You Being Served:

• Mr Harman, replacing Mr Mash, joins the show in series 4 with no introduction. Yet all the cast know him.

Buffy The Vampire Slayer

• The character of Dawn, Buffy's sister, is introduced in the first episode of season five as if she had always been a part of the show and was known to all the regular characters. This was later explained as a major plot point to the season.

Coronation Street:

• Kelly Crabtree was first featured on her final day working at the factory - we were told that she had been there for some time, however she had never been seen nor mentioned in the series previously. Soon afterwards she returned to working at the factory and became a regular character.[citation needed]

The Cosby Show:

• In the pilot episode, an exasperated Clair Huxtable says to her husband "Why do we have four children?" He replies "Because we do not want to have five." However, in subsequent episodes, the Huxtables refer to having five children, with an oldest daughter away at Princeton. Sabrina Le Beauf made an appearance as Sondra Huxtable in a first-season episode, but was not listed on the opening credits until the second season. There was no explanation in the series for the addition of Sondra, though after the series ended Bill Cosby explained that the character of the eldest, collegiate daughter was added to provide a positive role model for black youth.[citation needed]

Degrassi: The Next Generation:

• Jay Hogart appeared in the episode Gangsta, Gangsta when he'd never been there before.[citation needed]

Designing Women:

• Jan Hooks replaced Jean Smart at the beginning of the sixth season, playing Carlene Dobber, the sister to Smart's Charlene Frazier character. Despite several previous episodes giving details about Charlene's family, her sister Carlene was never mentioned.[citation needed]

Great Teacher Onizuka:

• Azusa's younger sister Makoto was never mentioned until she suddenly appeared in an episode because Azusa was kidnapped and detained by Teshigawara. Onizuka being too stupid to investigate it himself, Makoto uses her very advanced detective skills to find her.[citation needed]

Invader Zim:

• In the last episode of the series, "The Most Horrible X-Mas Ever", Zim is shown going about his business with a new sidekick: a purple, floating moose called "Minimoose". Minimoose is revealed to be robotic in origin and highly powerful, with a "Vortian Doomsday device hidden in his Nubs of Doom". Part way through the episode, Dib, held captive by Zim, notices Minimoose and asks "What is that?" to which Zim responds "Oh, uh, that's MiniMoose, my other sidekick, yeah. Yup, been with me the whole time!". Minimoose's origin episode had been written, but due to the show being cancelled by Nickelodeon was never produced. The X-Mas episode was originally scheduled to appear later in that series, after many of the unproduced episodes (including Minimoose's introduction), but the series was delayed, and the Christmas episode was shown at Christmas that year anyway - hence the disparity in the timeline, and (in true Zim style), making light of the unintended error rather than rewriting the whole episode without Minimoose.[citation needed]

The Jeff Foxworthy Show:

• During the entire first season, Jeff's wife Karen was pregnant with their daughter, which she gave birth to in the last episode of the first season, and they already had a son. On the first episode of the second and final season, they have another son who looks about four years old, but there is no sign of a daughter. Also, the first son hasn't aged at all since the first season.[citation needed]

Mama's Family:

• Neighbor Iola Boylan did not appear until three years into the show's run, but according to the show she had lived next door to the Harpers her entire life. Although viewers only see a small fraction of a sitcom family's lives — leaving many relatives, friends, acquaintances and enemies unseen — Iola's absence is notable because her closeness to the family implies she would likely have figured into a number of scenes in the first three seasons.[citation needed]

Matlock:

• For the 7th season, Ben's second daughter Leanne MacIntyre joined the cast, despite never being referred in the series before.[citation needed]

Prisoner:

• In 1984, six years into the run of this prison-based soap opera and with no original characters remaining amongst the prisoners, new characters Lou Kelly (Louise Siversen) and Alice Jenkins (Lois Collinder) were portrayed as having been in the cell block since the story events of the very first episodes from 1979. Siversen had played several bit parts in earlier years (though not as a prisoner) and had spent about a year as a cell block extra while Collinder had made a few brief appearances as a prisoner, but not as these characters.[citation needed]

Sonic the Hedgehog (SatAM):

• In the show's second season, the character Dulcy the dragon (voiced by Cree Summer) is added to Sonic's group of friends, the Freedom Fighters, without any explanation.[citation needed]

The Sopranos:

• In the fifth season we meet Tony's cousin, Tony B (Steve Buscemi). We are told that Tony and he grew up together, thought of each other as brothers, used to pick on Christopher, etc. And even though we'd seen Tony go through his whole life in his therapist's office for five years, Tony B was not mentioned until he joined the cast. This was acknowledged when Bobby Jr. asked Tony B. "How come I've never heard of you until now?" in the episode "Rat Pack".[citation needed]

South Park:

• In one episode where Kenny was in a vegetative state, Kenny's family appeared with a female child that suddenly appeared.

Space: 1999:

• In the second season, Security Chief Tony Verdeschi (Tony Anholt) is a regular character, part of the command staff and treated by the other regulars as if he has always been. However, not only his character had never been seen before, but also no explanation was given as to how he had somehow been promoted to that level. Alpha hadn't even had a security chief in the first season. By contrast, an entire episode was devoted to the introduction of Maya, the other new regular that season.[citation needed]

Star Blazers:

• In the third series "The Bolar Wars" Gamilon Leader Desslok had a Sergeant Masterson as his chief adjutant. This role had previously been filled by General Talan in the previous series and movies. This inconsistency does not exist in the original Japanese version in which the Masterson character is supposed to be Talan. Unlike the first two seasons of the show, the third season was dubbed into English by a different company who failed to fully research the characters.

Star Trek (The Original Series):

• Ensign Pavel Chekov is on the bridge from the second season. There was no introduction or mention of him joining. This caused a discontinuity in Star Trek II:The Wrath of Khan when Chekov and Khan (a guest star in the opening season) recognize each other.

On rare occasions, a Cunninghamed character returns to the show just as suddenly as they have left. This is arguably the worst case of Cunningham Syndrome, as not only does a viewer have to endure the character's abrupt and unexplained disappearance, but also their equally abrupt and unexplained return, especially if the return happens much later in the series, when the other characters have enough time to develop and grow without the returned character. Like Reverse Cunningham, the awkward break in their appearance, and the troubles with reintroducing them into the show, make a Lazarus Cunninghamed character a very underused occurrence, though it has happened.

Family Matters

• The character of Rachel Crawford (played by Telma Hopkins) suddenly disappears from the show after the fourth season, and was not seen or mentioned again throughout season five. The character reappears in season six without any explanation of her disappearance in the previous season, hinting that she was there the whole time but just wasn't seen.

Boy Meets World

• The character Stuart Minkus did not appear onscreen for four seasons, but when Cory and Shawn ask him where he has been for those years in the graduation episode, Minkus replies that he has merely been in another part of the school.

Family Guy

• Though Joe Swanson's son, Kevin, was abruptly said to have been killed in Iraq after a long absence, he returned alive in the season ten episode "Thanksgiving", where it is explained that he actually faked his own death.

James Bond film series:

• Felix Leiter and Bill Tanner come and go throughout the series with there departures and returns never being explained.

Mortal Kombat series:

• The tiger-Shokan Kintaro vanished from continuity after Mortal Kombat 2, with only a non-canon appearance in Mortal Kombat Trilogy and Mortal Kombat: Deception's Konquest mode, before reappearing in Mortal Kombat: Armageddon. While there are many rumors as to what happened to him, none have been confirmed, and until his bio is released by Midway, the mystery of where he went after MK2 remains just that.
