Poorly Disguised Pilot

"Rule of thumb: whenever a show does an episode focusing on a bunch of people you've never seen before and never do again, it's a pilot for a new show."

Episode in which the show's primary characters take a back seat to secondary or, more likely, brand new characters in order to test the waters for a separate show. Differs from the traditional Spinoff in that the characters are clearly jammed in there just for the sake of the new show; it's not a matter of primary characters becoming popular enough to break out on their own. Not many of these pilots get picked up, however.

Another common term for this is "backdoor pilot"; however this can refer to other things as well, most notably a pilot broadcast as a special or Made-for-TV Movie that will be picked up as a series only if the ratings are good enough.

Much like any pilot, the version of the series that makes it to air may have actors or settings changed. The version of Empty Nest that made it to TV was much different than the Poorly Disguised Pilot on The Golden Girls, and the proposed Aquaman series would have starred a different actor than the one who guest-starred on Smallville.

As a general rule, if you're watching a show and you find yourself asking questions like "Where did everybody go?", "What are we doing here?", "Who are these people?", or, above all, "What is going on here?", then you're watching a Poorly Disguised Pilot.

Other symptoms of a Poorly Disguised Pilot include:

Before the concept of the Season Finale took off, these were often aired as the last episode of a season.

The Opposite Trope is Fully Absorbed Finale, when what is functionally the last episode of a show appears in another show. See also Pilot Movie.

  • This is apparently the reason for Ruri being Put on a Bus in Oreimo; so she could receive a spinoff.
  • One episode of Outlaw Star had Gene and co encountering two characters from Angel Links, a spinoff series that would debut a year later.
  • Read the first chapter of Fushigi Yuugi Byakko Ibun and see how the legend of the priestess from another world and her chosen warriors is mentioned briefly, but overall has no purpose in the chapter. The main character Suzuno doesn't even actively appear, she only shows up as an image on the final page. The chapter barely feels like it has anything to do with Fushigi Yuugi to begin with, with the sole revelation being that Nirusha is actually Seiryuu warrior Miboshi!

    Comic Books 
  • In Fables, Jack goes to Hollywood and makes a trilogy of LOTR-ish films about himself. He eventually gets caught and exiled from Fabletown, leading into the Jack of Fables series.
  • The first three issues of the Re Tool of Adventures of the Fly called "Fly-Man" is basically this for the originally version of the Mighty Crusaders.
  • Lampooned in Cable & Deadpool #38.
    Deadpool: "Bob, Agent of Hydra". One would almost think we were forcing you down our readers' throats as some kind of possible limited series pitch or something.
  • The "Bloodlines" crossover in DC comics of the early 90s was basically one massive series of Poorly Disguised Pilots, with that year's "annual" issue for each ongoing series showcasing the origin of a new superhero. Although a few of these "New Blood" characters were featured in mini-series or new ongoing series, the only one that managed any kind of success was Garth Ennis's Hitman, which spun out of The Demon.
  • Marvel tried a similar tactic with their 1993 annuals, which each introduced a new character. Of the 27 new characters created, the only one who really caught on was Legacy, who fronted his own series for a while as the new Captain Marvel.
  • DC tried this again in 2000 with their Planet DC event, where once again, a bunch of annuals introducing new characters were launched. Pretty much the only new heroes who saw any real use were Nemesis (introduced in the JSA annual) and Bushido (introduced in the Titans annual), and even those two ended up being killed off.
  • Likewise, an issue of The Mighty Thor during the "Acts of Vengeance" crossover in Marvel Comics showcased the New Warriors, which received their own book months later!
  • Heroic Publishing will occasionally use its Champions title in this manner. Likewise, Heroic Spotlight.
  • Marvel Comics, at the start of the Silver Age, had what are now called "tryouts". For instance, one Human Torch story featured a Captain America impostor and asked the readers if they wanted to bring back the real Captain America. On the other hand, the fevered imagination of fans (and/or the greed of comic book speculators) has been prone to see tryouts in Marvel's pre-superhero era even when links between the precursor and later characters are tenuous at best (e.g., a '50s monster character who happened to be called "Hulk" and was renamed Xemnu the Titan once the Incredible Hulk showed up to avoid confusion).
  • DC Comics did the same thing earlier, occasionally trying out the idea of a character before going forward with "the real thing." DC's first Distaff Counterpart characters to Superman (Lois Lane temporarily getting powers and operating as "Superwoman" and Superboy turning into a girl and operating as "Claire Kent, Super-Sister") were probably not tryouts so much as one-shot story ideas. But 1958's "The Girl of Steel" was clearly a dry run for Supergirl. In that story, Jimmy Olsen uses a magic totem to wish for a "Super-Girl" who would be a companion and helpmate for Superman. It doesn't work out all that well, and Jimmy ends up wishing the girl out of existence at her own request (It Makes Sense in Context... sorta.) Reaction was positive enough that DC introduced Kara Zor-El, the "real" Supergirl, shortly after.
  • Both Marvel and DC often launched features from titles that had no "regular" star. Those features would then, if popular enough, get their own titles:
    • Spider-Man is perhaps the most famous case. He first appeared in Amazing Fantasy, a series that was being canceled. As we all know, that particular issue was a miserable failure.
    • Marvel would revive Amazing Fantasy in the 2000s; no series was launched directly from it, but Araņa would eventually get her own title as Spider-Girl.
    • More successful than her was probably Amadeus Cho, who co-starred in The Incredible Hercules.
    • Only a few other characters, such as Dr. Monica Rappaccini, Death's Head 3.0, Monstro, and Vampire by Night, ever showed up anywhere after the series, and even then mostly in supporting roles.
  • DC's Showcase launched a large number of successful features, including the Silver Age versions of The Flash, Green Lantern and The Atom, Challengers of the Unknown, Metal Men, Sea Devils, and many more. The series lasted from 1956 to 1970, and was briefly revived from 1977 to 1978. The series introduced and/or spotlighted:
    • Fred Farrell, Fire Fighter debuted in issue #1 (April, 1956). Did not make it as a protagonist but has had his share of appearances in crossover stories.
    • Issue #2 (May, 1956) was a theme issue for stories set in the wilderness, introducing three would-be protagonists. The first was Eagle Feather, a Native American shepherd who has to hunt and kill the mountain lion which preyed on his sheep. The second was an unnamed Orphan Runaway who managed to bond with a stray dog and save lives in a fire. The third was Billy, a trained circus bear, who is lost in the woods and has to survive in his new surroundings. The issue was not deemed popular enough to have sequels.
    • issue #3 (July, 1956) featured Doug the "sardine", a trainee frogman (term for combat divers) who has to prove to his fellows that his short stature is not a liability to the team. Again not a winning concept for an ongoing series.
    • The Flash /Barry Allen debuted in issue #4 (October, 1956). He also headlined issues #8 (June, 1957) and #13-14 (April-June, 1958). The character had enough positive feedback for DC to revive the old The Flash series with Barry as the protagonist, starting with issue #105 (March, 1959). His ongoing lasted to 1985, making the greatest hit to graduate from Showcase.
    • Issue #5 (November, 1956) was another theme issue, featuring "manhunters" (people who take part in an organized search for a wanted man or fugitive). The protagonists were Detective Harry Fowler, FBI Agent Don Reed, and Sympathetic Inspector Antagonist Frank Drew who was hunting master criminal The Eel around the globe. None of the characters was deemed popular enough to reuse in later stories.
    • The Challengers of the Unknown debuted in #6 (February, 1957). They also headlined #7 (April, 1957) and #11-12 (December, 1957-February, 1958). They gained enough positive feedback to gain their own series, starting in May, 1958. Their original series was published regularly to 1970, and sporadically to 1978 when it was cancelled for good.
    • Lois Lane headlined issues #9-10 (August-September, 1957). Feedback was positive enough for Lois to gain her own series, starting in March, 1958. Her ongoing lasted to 1974.
    • Space Ranger debuted in #15 (August, 1958). This hero of The Future also headlined #16 (September, 1958), but failed to generate enough interest to launch an ongoing. He instead became the cover character of the anthology Tales of the Unexpected starting with issue #40 (August, 1959). He maintained this position to 1964.
    • Adam Strange debuted in #17 (December, 1958). He also headlined #18-19 (February-April, 1959). Feedback and sales were not enough to give him an ongoing, but were also too good to discontinue the character. He became the cover character of the anthology Mystery in Space, starting with issue #53 (August, 1959). He was regularly featured there to 1965.
    • Rip Hunter, Time Master debuted in #20 (June, 1959). He also headlined #21 (July, 1959) and #25-26 (March-May, 1960). The Time Traveler generated enough interest to "graduate" to his own ongoing series, starting in April, 1961. His ongoing lasted to 1965.
    • Green Lantern /Hal Jordan debuted in #22 (October, 1959). He also headlined #23-24 (December, 1959-February, 1960). Feedback and sales were positive enough for Hal to "graduate" to his own ongoing series, starting in August, 1960. His ongoing was regularly published to 1972. It was revived in 1976 and (with a couple of revamps on the way) lasted to 1988.
    • The Sea Devils debuted in #27 (August, 1960). They also headlined #28-29 (October-December, 1960). They were a quartet of scuba-diving adventurers with notable similarities to both the earlier Challengers of the Unknown and the later Fantastic Four. Feedback and sales were positive enough for them to "graduate" to their own ongoing series, starting in October, 1961. It lasted to 1967.
    • Aquaman and Aqualad headlined issues #30-33 (February-August, 1961). While the main character was already appearing in anthology series, this trial run established that Aquaman could work with longer stories. He "graduated" to his own ongoing series, starting in January 1962. His ongoing was published to 1971, was revived in 1977 and was cancelled in 1978.
    • The Atom /Ray Palmer debuted in #34 (October, 1961). He also headlined issues #35-36 (November-December, 1961). Feedback and sales were positive enough for him to "graduate" to his own ongoing series, starting in July, 1962. His ongoing lasted to 1969, with a brief revival in 2010.
    • The Metal Men debuted in #37 (March-April, 1962) and were reportedly intended as a one-shot concept to begin with. But due to positive feedback, they also headlined #38-40 (June-September, 1962) and "graduated" to their own ongoing series, starting May, 1963. Their series was regularly published to 1970, had revivals in 1973 and 1976, and was cancelled in 1978.
    • A revamped version of 1940s character Tommy Tomorrow headlined issues #41-42 (November, 1962-January, 1963), #44 (May, 1963), and #46-47 (September-December, 1963). The regular Tommy stories typically featured the character as an experienced officer, while the revamped stories covered his training years and the earliest points of his career. Neither version generated reader interest, so the character landed from Showcase to Comic Book Limbo.
    • James Bond headlined issue #43 (March, 1963). Basically, DC gained the rights to reprint a British comic book adaptation of the film Dr. No. While they also licensed the rights to create their own stories with the character, they never used them and the license expired c. 1972.
    • Sgt. Rock headlined issue #45 (August, 1963). He was already the cover character of an anthology series, but DC apparently considered him for "graduation" to his own series. He did not "graduate", and continued dominating the anthology title Our Army at War to 1977. The series was then renamed after him.
    • Cave Carson headlined issues #48-49 (January-March, 1964) and #52 (October, 1964). The character was a spelunker and Tunnel King. Again there was little to no reader interest and the character ended up in Comic Book Limbo.
    • King Faraday headlined issues #50-51 (May-July, 1964). In this case the stories were reprints of his 1950s Spy Fiction adventures. While it was hoped that the stories would enough to warrant a revival of the character, there was no reader interest and consequently no revival.
    • G.I. Joe headlined issues #53-54 (November, 1964-January, 1965). An adaptation of a then-new toy from Hasbro, again nothing really came of it.
    • Doctor Fate and Hourman headlined issues #55-56 (April-June, 1965). DC had recently revived the Justice Society of America and was variously testing the waters for further use of the characters involved. These issues did not generate enough interest for either hero to get his own series. Their lasting mark was a successful revival of 1940s villain Solomon Grundy who would become a recurring character again. As for the heroes, they remained supporting characters of the Justice League of America for several years.
    • Enemy Ace headlined issues #57-58 (August-October, 1965). He was then a fairly recently-created character and the stories helped flesh him out, but again not enough reader interest and no series for him. At least for a while. He became the cover character of the anthology Star-Spangled War Stories from 1968 to 1970.
    • The Teen Titans headlined issue #59 (December, 1965). Feedback was positive and the Titans "graduated" to their own series in February, 1966. Their ongoing series was published regularly to 1973, was revived in 1976, and cancelled in 1978.
    • The Spectre headlined issues #60-61 (February-April, 1966) and #64 (October, 1966). The character had not been used in two decades and these issues successfully revived him. It took a while to fully re-establish him but he "graduated" to his own series in December, 1967. His ongoing series lasted to 1969.
    • The Inferior Five debuted in #62 (June, 1966). They also headlined issues #63 (August, 1966) and #65 (November, 1966). A Super Team consisting of inept super-heroes, they were positively received. They "graduated" to their own title in April, 1967. Their ongoing was published regularly to 1968, and then was briefly revived in 1972.
    • B'wana Beast debuted in #66 (February, 1967). He also headlined issue #67 (April, 1967). He was a Beastmaster who could create Mix-and-Match Critters. The character received mostly negative feedback and a planned third issue was never created. The character fell to Comic Book Limbo.
    • The Maniaks debuted in #68 (May, 1967). They also headlined issues #69 (July, 1967) and #71 (November, 1967). The characters were a rock group consisting of three guys and one woman, having wacky adventures. The woman Silver Shannon served as Ms. Fanservice and the Gold Digger in search of rich mates. At the finale of each issue the Maniaks would Break the Fourth Wall and appeal to readers, asking them to support their tryout in Showcase. It didn't work and the Maniaks entered Comic Book Limbo. Silver seems to be the only character actually remembered by later writers, as she was revived as a supporting character in the Power Company (2002).
    • Binky Biggs, the 1940s teenage humor character, headlined issue #70 (September, 1967). DC was at the time attempting to revive its defunct teenage humor-line in an apparent attempt to compete with Archie Comics. It seems DC didn't really wait long enough to do a proper tryout, as he did "graduate" to his own series after a single issue. His original series Leave it to Binky was revived with issue #61 (June, 1968) and lasted under this name to 1970. The series was then renamed to Binky, and continued to 1971. It was again briefly revived in 1977, but that was the end of it and the character.
    • Issue #72 (February, 1968) reprinted older Western Stories, notably including sample stories of the Trigger Twins and Johnny Thunder. They were characters from the classic Western line of DC which had lasted from 1948 to 1961. Whether DC was seriously considering revivals for them, or this was a Filler issue is unknown. But nothing came of it.
    • The Creeper debuted in #73 (April, 1968). DC did not really wait for feedback and immediately launched an ongoing series for him: Beware the Creeper (May, 1968). It lasted to 1969.
    • Anthro debuted in #74 (May, 1968). He was supposedly the first Cro-Magnon boy born to a Neandertal tribe. His adventures were supposed to chronicle the birth of modern humanity, his descendants. Again DC did not really wait for feedback and launched an ongoing for him in August, 1968. It lasted to 1969.
    • Hawk and Dove debuted in #75 (June, 1968). They were two heroic siblings with opposing ideologies, serving as Straw Characters. Hawk was a militant guy who advocated violence in support of a proper cause, and let his fists do the talking for him. Dove was a pacifist who advocated finding peaceful resolutions and reaching a compromise. Their solutions to any given situation were supposed to reflect upon the political and ideological conflicts of 1960s. DC once more did not wait for feedback and launched an ongoing for them in September 1968, The Hawk and the Dove. It lasted to 1969.
    • Bat Lash debuted in #76 (August, 1968). DC was inspired by the popularity of Spaghetti Westerns to launch a new Western series, but with a twist. In contrast to the unambiguous heroes of their older series in the genre, Bat was a Loveable Rogue, a Womanizer, a Professional Gambler, and a Reluctant Warrior. He did not actively look for trouble, but his Walking the Earth often landed him in troubled places. DC was too confident in the concept to wait for feedback, and launched an ongoing for him in November, 1968. It lasted to 1969.
    • Angel and the Ape debuted in #77 (September, 1968). Without waiting for feedback, DC launched their ongoing series in December, 1968. It kept its name for 3 issues, then was renamed to Meet Angel to emphasize the female partner of the duo. Under the new name it lasted to the end of 1969.
    • Jonny Double debuted in #78 (November, 1968). He was a Perpetually Broke Private Detective who tried to make a living on what his customers were willing to pay him. DC was not eager to give him an ongoing series, so the character went straight to Comic Book Limbo. In this case, however, writers of the 1970s did find use of him in several series headlined by more popular characters. So Jonny is better known for supporting roles in stories of the Challengers of the Unknown, Supergirl, Wonder Woman, and Kobra.
    • Dolphin debuted in #79 (December, 1968). She was a mysterious Apparently Human Merwoman with an implied Wild Child background. Her first appearance covered her first contact with human civilization and learning basic language skills. Again DC had no real plans for her and she went straight to Comic Book Limbo. In the 1980s she became a member of the Super Team Forgotten Heroes, which consisted of other characters who had not been used in a while, took part in the Crisis on Infinite Earths, and had a team-up with Animal Man. In the 1990s, she joined the supporting cast of Aquaman.
    • The Phantom Stranger headlined issue #80 (February, 1969). In this case DC was eager to revive the 1950s character, and launched his new series in June, 1969. It was regularly published to 1976. It had a brief revival in 2010.
    • Windy and Willy debuted in #81 (March, 1969). They were actually modified versions of older characters. DC had earlier published a comic book adaptation of The Many Loves Of Dobie Gillis and wished to reuse it, in another attempt to appeal to the market for teen-humor stories. But they weren't willing to pay the owners of the television show just to reprint stories they already legally owned. So, the original protagonists Dobie Gillis and Maynard G. Krebs were modified to Willy and Windy. Once again DC did not wait for any feedback ,and launched a new ongoing for the duo in June, 1969. It flopped in sales and was cancelled after only 4 issues. It was the least successful series to come out of the pages of Showcase.
    • Nightmaster debuted in #82 (May, 1969). He also headlined issues #83-84 (June-August, 1969). The basic concept was that modern-day rock musician Jim Rook and his girlfriend Janet Jones walk into The Little Shop That Wasn't There Yesterday and find themselves in a Sword and Sorcery dimension. Jim learns that he is a descendant and a Legacy Character to a local sword-wielding hero. Inheriting the Sword of Night, a Cool Sword with mystical powers, Jim becomes the Nightmaster and gets involved in the conflicts of his new home dimension. The Nightmaster did not sell well enough to "graduate" to an ongoing series, and went straight to Comic Book Limbo. He was revived in the 1990s with cameos in Animal Man and The Books of Magic, and more substantial roles in Primal Force and Swamp Thing. In the 2000s, he joined the Shadowpact.
    • Firehair debuted in #85 (September, 1969). He also headlined issues #86-87 (November-December, 1969). Firehair was a white boy Raised by Natives, named for his Red Hair. As an infant in the Old West, Firehair experienced the violent death of his parents at the hands of the Blackfoot tribe of Native Americans. But the leader of the tribe decided to raise the boy as his own son. As a young adult, Firehair finds himself with all the supreme fighting skills of the Mighty Whitey, but none of the respect. His own tribe despises him because of his looks, while the White Man sees his as a strange-looking Savage Indian. So he starts Walking the Earth, trying to find a place which will truly accept him, and saving some lives in the process. According to his origin story, a shaman predicted that his destiny will be to be constantly despised by both his own people and by anyone he tried to help. The concept did not sell well enough and Firehair went straight to Comic Book Limbo. He was revived in 1971, when he briefly became the second feature of the Tomahawk series.
    • Jason Grant debuted in #88 (February, 1970). He also headlined issues #89-90 (April-June, 1970). The story had a young man on a personal quest. In a Deathbed Confession, Jason's "father" reveals that Jason is adopted. His real father had been killed by orders of Crime Lord Tuborg. The same man who caused the fatal wounds of the adoptive father. Now Jason has to locate his Long Lost Sister, and the hidden records or evidence of Tuborg's past misdeeds. Armed with a grainy photo, a guitar and a second-hand import motorbike, Jason wonders Western Europe to fulfill his quest. The concept did not sell well and Jason went to Comic Book Limbo. He has had a couple of cameos over the years, but nothing substantial.
    • Manhunter 2070 debuted in #91 (August, 1970). He also headlined issues #92-93 (August-September, 1970), which were originally the last issues of Showcase. This version of Manhunter is a space-traveling Bounty Hunter. In 2053, young Starker witnessed the murder of his father and was himself enslaved by Space Pirates. He spend his years of captivity in secretly studying and learning as many of his captors' skills as he could. Which he eventually used to bargain for a position in their crew. He used said position to destroy them from within, killing all those involved with the murder of his father and delivering the rest to the authorities. This act taught him that one can make a living by hunting outlaws. By 2070, Starker is a veteran bounty hunter with a ruthless streak. The concept did not sell well enough to give him a series and this Manhunter went to Comic Book Limbo. Several writers have since revived him for various space-faring adventures.
    • The Doom Patrol headlined issues #94-96 (September, 1977-January, 1978), the first ones of the revived series. With most of the original members dead, these issues got to introduce some new blood. The new version was not popular enough to "graduate" to their own series, though they served well as guest-stars in various titles.
    • Power Girl headlined issues #97-99 (February-April, 1978). Though possibly well-received, the DC Implosion resulted in the cancelling of many of the ongoing titles of the company. It was no time to launch a new title.
    • Issue #100 (May, 1978) was a Milestone Celebration and a change of pace of the series. Instead of a sales pitch for a new series, this featured a Massive Multiplayer Crossover. A Crisis of some type requires heroes from different eras to join forces and try to rescue reality itself. These heroes happened to include almost every character to ever headline Showcase, in a celebration of the series' history. Most characters get cameos, but the story serves as A Day in the Limelight for Lois Lane and Angel O'Day who co-operate in actually ending the Crisis.
    • Hawkman /Katar Hol headlined issues #101-103 (June-August, 1978). Basically he had a crossover with Adam Strange, featuring a war between the planets Rann and Thanagar. Nothing came of it, and Hawkman remained a featured player in the Justice League of America.
    • OSS headlined issue #104 (September, 1978), with stories set in World War II and featuring various agents. Possibly a sales pitch for a war-themed series, but nothing came of it. Showcase itself was cancelled at this point, though there were two more issues awaiting publication. Their material became available later through other formats.
    • Deadman would have headlined #105, as a sales pitch to get him an eponymous series. No such luck until 1985.
    • The Creeper would have headlined #106, since there were creators campaigning to get him a second series. No such luck until 1997.
    • There were known plans for subsequent issues. At least one featuring the Huntress /Helena Wayne and a World of Krypton story which would further flesh out the background of Superman's doomed homeworld. This version of Huntress would get a backup series in the Wonder Woman comic which was often more popular than the main feature, while World of Krypton would be published as a mini-series in 1979.
  • DC tried to get a second try-out book off the ground in the mid-70s, partially as a replacement to the by-then-canceled Showcase. It was called First Issue Special, and it started because publisher Carmine Infantino realized first issues sold better and wanted a series where every issue was the first (seriously). Incidentally, this meant that each premise was only afforded one issue, whereas most often in Showcase a feature would headline for two or three issues. It only ran for 12 issues, and it only launched one comic, Warlord. Warlord ended up running about ten times as long as First Issue Special did — from 1976 to 1988. About half of the other issues featured established characters like the Creeper or Dr. Fate; the non-Warlord characters created for First Issue Special mostly disappeared after their headlining ish, though the Green Team received a quickly-canceled revival in 2013.
  • For various convoluted reasons, Marvel was limited to printing a certain number of titles in the '60s. When no longer under that restriction, Marvel launched several of its own Showcase-style titles, such as Marvel Spotlight, which launched features such as Werewolf by Night, Ghost Rider, and Spider-Woman.
    • Some of this was due to the introduction of The Comics Code. Moral Guardians convinced comic publishers to ban horror-related subjects like vampires, ghouls, and the undead, and those titles floundered for awhile, eventually throwing out different subjects and characters to see what would stick, easy enough to do as many of them were anthology comics with 3-4 stories per issue. Journey Into Mystery started telling the story of The Mighty Thor, the Incredible Hulk (after his one-shot series was canceled) started to guest star in Tales to Astonish. Tales of Suspense was a sci-fi anthology, and the stories introducing Iron Man and reintroducing Captain America spawned their own titles.
    • Earlier, in the late 1960s, Marvel did it with "Marvel Super-Heroes", a larger-than-normal comic whose lead feature launched such stars as Captain Mar-Vell, KaZar, and the Guardians of the Galaxy, with classic 1940s and 50s stories backing it up!
      • The Guardians of the Galaxy got this treatment twice. First were introduced in Marvel Super Heroes in the late 60s and nothing came of it. A few years later they made guest appearances in Marvel Two-In-One and The Defenders before they got their own book as the stars of Marvel Presents.
  • Archie Comics tried to salvage their failing 1960s superhero line by using "Mighty Comics" as their "Showcase", featuring such heroes as The Web, The Shield, The Black Hood, and Steel Sterling. It wound up killing the line for about 15 years!
  • One Story Arc in Runaways was a Poorly Disguised Pilot for "Excelsior", a support group for former teen heroes that ended up getting sent to chase the main characters. It was eventually launched as The Loners, after it turned out that the trademark on "Excelsior" belonged to Stan Lee, who had put out a book about his experiences in comics by that title.
  • During the nineties, Spider-Man met during a battle with Hydra a superhero named "Shoc", obviously meant to appear in his own series. It was also pretty obvious who his Secret Identity was. Fortunately, he was quickly forgotten.
    • Speedball first appeared in a Spider-Man Annual that depicted him on the cover, soaring over both Spidey and Daredevil. The annual shoehorned Speedball into the main story and featured a solo back-up tale. This led to a short-lived solo series, Speedball The Masked Marvel. Despite this, the character has been around for about 30 years, was a prominent member of New Warriors, and played a large role in Civil War.
    • Amazing Spider-Man #86 was meant to set up the short-lived Black Widow solo series that appeared in Amazing Adventures.
  • Issue 99 of Gerard Jones's Justice League of America run was clearly an attempt to drum up support for a series about the altered children who took over the issue, the Strangebrood. This didn't pan out, and the Strangebrood never showed up again anywhere.
  • Kurt Busiek introduced the Power Company in an issue of JLA before quickly spinning them off in their own series.
  • In 2005, the anthology series Star Wars Tales featured two stories taking place in the Knights of the Old Republic era. One was issue sized while the other lasted only six pages. Two months after the release of the issue featuring the first story, a Knights of the Old Republic comic series was announced. It was likely that both ideas were created around the same time, however.
  • The notorious 'The Punisher Goes Black' story arc in 1992 that guest-starred Luke Cage served as a pilot for the 1990s Cage series.
  • The Punisher himself had his own pilot in the pages of Spider-Man (man, Spidey is popping up a lot).
  • Another famous case is Wolverine. He first popped up in an issue of the Incredible Hulk. The creators wanted to use him in other titles but didn't have a clear idea what they wanted to do with the character. They ended up tossing him onto the "X-Men", in large part because he had been identified as Canadian and they wanted "international" characters for the new team.
  • Chuck Austen's final few issues of The Avengers served as a springboard for the New Invaders. This was a particularly egregious example, as the finished product read like an Invaders story that just happened to guest star a few of the Avengers.
  • The second and third issues of the original Youngblood series gave one of the flip-sides to Shadowhawk and Supreme, respectively. The fourth issue featured a prelude to Pitt, but without the flip-book format.
  • The plot for Transformers: Generation 2 was kicked of in a Crossover with G.I. Joe.
  • The final issues of the Superman: Grounded storyline were intended by writer Chris Roberson as (among other things) a backdoor pilot for a "Supermen of America" series.
  • Christopher Priest has admitted he only added the Korean heroine Mystek to the Justice League Task Force during his run to set her up for her own mini-series. When plans for the mini-series were axed, Priest quickly killed her off.
  • New Teen Titans Annual #2 introduced us to The Vigilante, who got his own comic book the following month.
  • The second-to-last Teen Titans storyline by Felicia Henderson was meant to be a backdoor pilot for a new Static comic book series. The DC relaunch delayed the series and by the time it launched a year later, it had been retooled to the point that it literally abandoned every bit of set-up introduced in the Teen Titans arc.
  • The Blue Beetle and Hardware team-up in The Brave and the Bold included an extremely obvious set-up for a new Hardware solo series.
  • U.S. Marshal J.D. Hart features prominently in issues 42-44 of the original series of Jonah Hex, essentially acting as a co-star to Jonah in those issues. Hart was going to be spun off into his own book, unofficially titled Dakota, but that book never eventuated and Hart eventually returned as a supporting character in Jonah Hex.
  • The ninth issue of the original What If? series was probably intended to be this for a series starring the various heroes from Marvel's 1950s comics. Which did happen, albeit 30 years later, with Agents of Atlas. A much later issue of What If was the basis for the entire Marvel Comics 2 universe and Spider-Girl.
  • The current Nova volume had a story arc where the character met Justice and Speedball, two of the washed-up former members of the New Warriors. Around the same time, Superior Spider-Man Team-Up featured an arc where Otto encountered a new heroine named Sun Girl. The characters involved soon met and teamed up for the Marvel NOW! relaunch of New Warriors.
  • Uncanny X-Men #358 (August, 1998) was a spotlight issue for the Odd Couple of Bishop and Deathbird, established earlier, with them gaining a new ally and getting involved in a struggle against another version of The Empire in space. The issue is often commented on, in retrospect, as seeming to serve as a pilot or sales pitch for a Space Opera series or storyline, but if so the plans never materialized.
  • The crossover between Archie Comics' Sonic the Hedgehog and Image Comics served as a pilot episode for writer Ken Penders' incredibly short-lived, creator-owned The Lost Ones series.
  • The final arc of Ultimate Spider-Man featured a team-up between Spidey (Miles), Cloak & Dagger, Spider-Woman, and Bombshell. This same group appeared in the Cataclysm: Ultimate Spider-Man mini-series before being spun-off in their own book as the All-New Ultimates.
  • Early 00's Crisis Crossover Maximum Security was clearly an attempted launching pad for a few concepts, including a cosmic Avengers team and former stand-in Captain America US Agent. Agent did get his own series, but it was short lived.
  • Whether intended as one or not, the Fantastic Four three-parter that introduces Galactus serves as a backdoor pilot for the Silver Surfer.
  • Played with in DC Comics' Star Raiders — as a graphic novel, it's rather disjointed, with a Random Events Plot filled with numerous characters and details that are left unused. Justified in that it was originally intended as a longer Story Arc (with an option for an ongoing series) that got cancelled halfway through development, with an ending abruptly added to salvage the work that was already done.

    Fan Works 

Note: Remember, films that are created with the idea of releasing an Animated Adaptation in mind are Pilot Movies and should be listed there.
  • A large chunk of the plot in The Amazing Spider-Man 2, such as Harry Osborn's transformation into the Green Goblin and subsequent meeting with Gustav Fiers in The Stinger, was clearly meant to set up the Sinister Six movie.
  • Yes, this happens in film. Blade: Trinity was partially intended as a Poorly Disguised Pilot for Hannibal King and Abigail Whistler's "Nightstalker" characters. It didn't work out.
  • Similarly, the X-Men Origins: Wolverine has been stated to be a testing bed for films based on Gambit and Deadpool.
    • The fact that the two were the most common points of criticism (Gambit for Advertised Extra, Deadpool for They Changed It, Now It Sucks) would tell you it didn't work. However, Ryan Reynolds' Wade Wilson from before his disfigurement (and The Stinger with him) was considered quite awesome and so far, he's still intended to be the lead actor should a Deadpool film be made. However, though the movie left him salvageable (with the brainwashing apparently undone in the end, he's free to put on a mask and act like the Wade from the scenes people liked while having the comics' version of the face behind the mask), the later Deadpool movie that was released was a complete Continuity Reboot, because comic Deadpool usually doesn't have Eye Beams or Teleportation.note 
    • Years later, there were plans to have a new version of Gambit (played by Channing Tatum) appear in X-Men: Apocalypse to set him up for his own spin-off. The solo Gambit movie is still happening, but the planned appearance in Apocalypse was nixed.
  • And Marvel seems to like this a lot, because their first five films of the Marvel Cinematic Universe were meant to collectively lead into an Avengers film.
  • Daredevil was basically hacked to pieces by Fox executives to serve as a pilot for the Elektra spin-off. When given the opportunity to put out the movie as it was originally conceived, the director cut Elektra's screentime substantially, restored a half dozen missing subplots, and turned it into a movie that was actually worthwhile.
  • Before the James Bond movie Tomorrow Never Dies came out, producers announced that they were planning a spinoff movie series featuring Michelle Yeoh's character Wai Lin. That never happened, but similarly, there was much talk of a spinoff featuring Halle Berry's Jinx character from Die Another Day. The extent to which they were truly serious about either notion is unclear. Some suspect the talk in each case was simply pre-release hype ("The heroine in our next picture is such a great character, we're giving her a movie series of her own!"), although they did seem to at least make effort for the Jinx movie, for which they hired Stephen Daldry as director, got two months into writing the screenplay and had the series' production and costume designers create some early concept art before the poor performances of Charlie's Angels: Full Throttle, Lara Croft Tomb Raider: The Cradle Of Life and especially Catwoman led to it being canned.
  • There was talk of a Catwoman movie as a follow-up to Batman Returns. Michelle Pfeiffer wasn't very excited about the project and it never came to fruition until long after the Batman movie franchise had died. Eventually, the project was revived as a vehicle for Halle Berry, resulting in Catwoman.
  • Godzilla vs. Megalon was intended in part to launch a new Giant Hero, the robotic Jet Jaguar, for Toho Studios.
  • Indiana Jones
  • Fantastic Four: Rise Of The Silver Surfer is one for Silver Surfer. Many things in the movie don't happen (like the appearance of the Big Bad) in order to allow for the Silver Surfer spinoff, which never happened.
  • Wonder Woman will make her cinematic debut in Batman v Superman: Dawn of Justice in order to set up a solo Wonder Woman movie starring the same actress.

  • You wouldn't think this could happen in book form, but it has. Nancy Drew Files #39: The Suspect Next Door focused heavily on Nancy's neighbor, a girl named Nikki Masters. Not too long after, Nikki got her own spin-off, a romance series called River Heights. It lasted about 16 issues before getting run off the face of the earth and is largely forgotten now.
  • Rinkitink in Oz is a book in the Oz series of books that was originally written as a standalone fantasy novel in the land of Pilgaree. It didn't get published in that form, but eventually, L. Frank Baum changed it into an Oz book just by putting in what amounted to a gratuitous Crossover with some Oz characters. Mind you, at this point in his career, Baum was finding that whether he liked it or not, his books could only be commercially successful if they were Oz books.
  • Averted in Animorphs. A large cast of new characters, amply named the Axillary Animorphs, were introduced into the series near the climax. One would think this would mean shoehorning them into getting a spinoff right? Nope, they were all unceremoniously killed off.
  • It may not have been intentional, but the Past Doctor Adventures novel Corpse Marker by Chris Boucher ends up feeling like a poorly-disguised pilot for his Kaldor City audio dramas, with the Kaldorian characters (and Blake's 7 crossover characters) getting more page time than the Doctor and Leela.


     Video Games 
  • One of the major plots you spend time investigating in Another Code R is the mystery of Matt's father and what drove his business into the ground. While the bulk of the mysteries surrounding it are solved and tie in well to the main story, the final fate of his father is unresolved. It was supposed to lead into a separate game where Matt would resolve this plot, but cruel fate had the company go under before it could be produced.
  • The nightmare minigame in Metal Gear Solid 3: Snake Eater was a tech demo for an original game that was being developed by the Zone of the Enders team titled Guy Savage. However, Guy Savage was canceled and the minigame was removed in later versions of MGS3.
  • Super Mario Bros.:
  • Warcraft 3: The Frozen Throne's bonus campaign "The Founding of Durotar", with its shift from RTS to RPG gameplay, was a PDP for World of Warcraft.

    Web Comics 
  • Not Invented Here was launched in Unshelved in fall 2009. Though it's not even poorly disguised, since they brought in the NIH artist as a guest artist.
  • Prior to receiving her own series and eventually becoming the Platypus Comix mascot, Mulberry Sharona made some guest appearances in Marin Meadow, a series Peter Paltridge decided to discontinue around the time he came up with Mulberry.
  • Although T Campbell has never said so outright, the Penny and Aggie arc "The New Reality" appears to have been in part a trial run for a spin-off set in Hollywood and focusing on Sara (like the arc itself). In late 2010, Campbell held an eBay auction for the privilege of having a character named after the highest bidder, in a new webcomic to be launched the following year. The listing stated that names which appeared in the Penny and Aggie cast page would be ineligible, as would the names "Lucy, Hilary or Martin," three of the characters from "The New Reality" arc. In the end, Campbell followed P&A with an entirely different spin-off, QUILTBAG, which starred Sara and Lisa as college roommates.

    Web Original 
  • Parodied in the AH.com: The Series episode "Ze Poorly-Disguised Pilot", which focuses on occasional guest stars The Germans and their adventures for a week instead.
  • The third episode of the That Guy with the Glasses 2013 anniversary special The Uncanny Valley titled "The Reviewers" was actually the pilot episode of a potential new series, which was picked up a year later.
  • Ethan originally intended The Double Agent to be about reviewing other reviewers and also about random topics (as his first episode is about the worst candies in Halloween) after he left his first show Worst Music Of The Year behind, but he slowly warmed up talking about music again.

    Western Animation 
  • One episode of Wait Till Your Father Gets Home featured a Crossover with Car 54, Where Are You?, introducing Gunther as Erma's brother in law. The episode quickly focuses on the officers trying to find a missing kid, with the Boyles shoved into the background.
    • Wait Till Your Father Gets Home was one of two animated segments of Love American Style prepared as potential pilots (this was titled "Love And The Old Fashioned Father"). The second, Melvin Danger (as "Love And The Detective"), did not get past its initial airing on Style.
  • The Andy Panda short "Knock Knock" was in actuality a vehicle short for Walter Lantz's intended new star Woody Woodpecker, with the bird getting much more screentime than Andy and his poppa.
  • Gargoyles had "Pendragon", which ended with a resurrected King Arthur heading out to wander the world in search of Merlin and the Knights of the Round Table. This was in fact a Poorly Disguised Pilot for a show that never came to fruition.
    • The World Tour arc was rife with these. There was "The New Olympians", a Poorly Disguised Pilot for... The New Olympians. "Sentinel" was a more subtle predecessor to Gargoyles 2198. Lampshaded in the creator's "ramble" on the episode:
      Greg: The way this ended, you'd almost think we were setting up yet another spin-off. "That wacky alien Nokkar teams up with a doctor and two archeologists to save the world from invasion and learn a little something about getting along... all in one hotel room!"
    • Other episodes set up elements that would lead to spinoffs:
      • "Future Tense" with the Phoenix Gate being thrown into the timestream, setting up "Timedancer" (which also never came to fruition).
      • "Walkabout" , "Bushido", "Kingdom" and "The Journey" all have elements that feature in the Bad Guys series.
  • Fan speculation ran rampant that the Justice League Unlimited episode "Far From Home" was designed as a Poorly Disguised Pilot for a Legion Of Superheroes series that would have starred Supergirl and taken place in DCAU continuity; however, Bruce Timm denied this. The fact that a Legion cartoon started up the next year, starring Superman, is apparently just a coincidence.
  • Two episodes of Thomas the Tank Engine's sixth series pushed the engines into the background, to focus on a group of construction vehicles called Jack and the Pack. The proposed series was not picked up, but 13 episodes were filmed and a few years later went straight-to-video (albeit with the titles altered to make it seem Thomas and Percy were the stars of most episodes).
  • The last episode of Hong Kong Phooey, "Comedy Cowboys", used its full half-hour length to introduce a bevy of new characters (Honcho, The Mysterious Maverick and Posse Impossible) all evidently itching to get their own cartoon. (Only one, Posse Impossible, succeeded when it appeared on CB Bears.) Lampshaded in that Phooey does hardly anything in the episode, as they point out at the end.
  • Curiously, the Batman Beyond episode "Zeta" was not originally intended to be a pilot for The Zeta Project, but it was deemed a good enough premise that it got its own show, albeit one Cut Short by cancellation. They did completely redesign Zeta for the spin-off to look more human-like, which doesn't stop Batman from recognizing him in the crossover episode.
  • The episode "The Fear" from The Super Powers Team: Galactic Guardians is acknowledged by its writers as having been intended to lead into a solo Batman series. And in a way, it eventually did, since it was written by Alan Burnett, who went on to produce Batman: The Animated Series.
  • The Rugrats episode "All Growed Up" features an odd "vision into the future" where all the characters are about twelve years older and have their adventures grounded in something resembling reality, as opposed to the usually surreal and fantastic nature of the exploits of their toddler incarnations. Sure enough, the episode was quickly transformed into a series, Rugrats: All Grown Up!, which shows the Rugrats as junior high schoolers.
    • The episode where Suzie celebrates Kwanza with her family was meant to be this, as it was planned to have a spin-off featuring Suzie and her family. It never materialized.
  • Parodied in the DVD Commentary of the Avatar: The Last Airbender episode "The Western Air Temple", where they joked that Haru, Teo, and the Duke messing around in the temple was one of these for a spin-off called The Last Street Luger with a lost pilot episode that consisted of 22 minutes of Teo riding around in his wheel-chair while passing various kinds of plants.
  • The Simpsons episode "22 Short Films About Springfield" was a backdoor pilot for a Simpsons spinoff called "Tales from Springfield" that would showcase the lives of every character on the show who wasn't a member of The Simpson family. But the crew decided it would be too much work and the idea was abandoned.
  • The Fairly OddParents had an episode in their fifth season that was an episode of the Show Within a Show Crash Nebula. It was actually a pilot for a proposed spin-off, but plans never got off the ground.
  • There was a two-part episode of Bravestarr called "Sherlock Holmes in the 23rd Century", which was clearly designed as a backdoor pilot for a potential new series that never entered production because Filmation had fallen upon hard times by this point (Bravestarr ultimately went on to become Filmation's final, fully produced series). This bore no relation to the later DIC Entertainment series Sherlock Holmes in the 22nd Century, which like the two part episode in question, was set in "New London" (Bravestarr was set on the planet of "New Texas").
  • Arthur had a "Postcards from Buster" special, a while before the series.
  • Inversion: Codename: Kids Next Door were actually supposed to be supporting characters in a series concept by Tom Warburton. Cartoon Network saw the potential of the neighbors, and next thing you know, a "Kenny and the Chimp" short without the KND (although the wacky scientist in that short did make a few appearances in the main show as a Villain of the Week) ended up being part of the first KND episode instead of the other way around.
  • SpongeBob:
    • "vs The Big One": Notice all the named characters introduced, including one whose name (or rather, a viewer-friendly anagram of his name) is shouted by SpongeBob every time he appears. Note the utter absence of the show's usual humor style. Note the fact that SpongeBob and the gang didn't act out of character so much as they acted without character. There could have been anybody standing in for them, and everything would have played out the same way.
    • "The Bad Guy Club for Villains," which consists entirely of SpongeBob and Patrick watching an episode of Mermaid Man and Barnacle Boy (similar to the "Crash Nebula" pilot above).
  • Aqua Teen Hunger Force: The "Spacecataz" cold openings that aired during the third season were, when put together, intended to be the pilot of a spinoff miniseries featuring the Mooninites and Plutonians; the idea never got off the ground, and the show dropped the cold openings before the short could be aired in its entirety (though it's available on the volume 4 DVD.)
  • Thundarr the Barbarian did an episode where the heroes meet a male and female pair of younger adventurers; it was likely an example of this trope.
  • DuckTales:
    • The episode where Uncle Scrooge becomes the crime fighting "Masked Mallard". Originally just a one shot story, the fans and writers liked it so much they started coming up with ideas for a sequel episode. Then finally deciding there were just too many good ideas that they wanted to do and created Darkwing Duck.
    • The episode "Double-O-Duck" where Launchpad gets mistaken for a James Bond-style secret agent seemed to be the set up for a spin off, though the James Bond right-holders weren't too thrilled with the "Double-O" part. F.O.W.L. (Fiendish Organization for Wold Larceny), introduced in the episode, became the main villains for Darkwing Duck.
  • Not really a pilot, but Cleveland got more attention than normal on Family Guy after his spin-off was announced.
  • Played With in South Park with "Butters' Very Own Episode." It seems like A Day in the Limelight episode, but actually set the stage for Butters to become an Ascended Extra after Kenny's longer-than-average death.
  • Tijuana Toads, a 1970s series produced by De Patie Freleng Enterprises, did this with Crazylegs Crane, Japanese Beetle, and the Blue Racer. The Blue Racer got his own series immediately after the Toads ended (with the Japanese Beetle appearing as a recurring character). Crazylegs Crane, however, had to appear in several Toads shorts (and even a few on the Blue Racer) before he finally got his own series in 1978, as a segment on the All-New Pink Panther Show.
  • Spider-Man: The Animated Series was rife with crossovers with the rest of the Marvel Universe, and the writers have since revealed that the two-parter with Daredevil was meant to launch another series, which ended up not being made. Also the last episode of season 4 really seems like they were trying start a Prowler TV spinoff.
  • Spider-Man And His Amazing Friends also featured various episodes where the Power Trio would encounter several other Marvel heroes, including the X-Men. Notably, Wolverine used the same Australian accent he used on the later "Pryde of the X-Men" pilot, even though he's Canadian.
  • The Incredible Hulk appeared in backdoor pilots in both Iron Man and Fantastic Four, before being spun off into his own cartoon (which aired on UPN rather than Fox Kids).
    • Ghost Rider appeared in an episode as a backdoor pilot for his own cartoon on UPN, which was not picked up. This had the effect of preventing the character from appearing in Spider-Man: The Animated Series, as the Fox execs did not want to promote a character who was going to be used by a rival network.
  • The (alleged) Betty Boop short Popeye The Sailor. While Betty was in the cartoon for about 30 seconds, a certain one-eyed sailor took up most of the screentime, and then got his own cartoon series.
  • Before starting their Little King shorts, Van Beuren Studios made two shorts based on the Little King's companion strip, "Sentinel Louie", which were both released as part of their Aesop's Film Fables series of shorts.
    • "Plane Dumb" feels like a prototype for the two Van Beuren Amos n Andy shorts, since the bulk of the cartoon has Tom & Jerry disguised in blackface makeup and acting like Amos N Andy, even talking a lot, something they almost never did in previous shorts.
  • The "Adventures of Sir Johan and Peewit" episodes in Season 2 of The Smurfs came off as this. This is the opposite of the original French language comic where the Smurfs originally appeared in the Johan et Pirlouit album La Flute ā Six Schtroumpfs ("The Six Smurf Flute") before getting their own series. This also explains why the Smurfs take so long to turn up in the movie The Smurfs and the Magic Flute (based on the aforementioned album).
  • Disney produced a CG/hand-drawn animated hybrid movie that served as the pilot to the TV series Buzz Lightyear of Star Command, book-ended by the CG characters from Toy Story actually watching the movie in Andy's room.
  • Pluto's Judgement Day: Despite being labeled as a Mickey Mouse short, this is actually one of the first Classic Disney Shorts to focus almost entirely on Pluto.
  • Fluppy Dogs was intended as a pilot for a television series. The movie was not well-received, and the series was never picked up.
  • Groove Squad, an animated movie featuring three cheerleaders who gain super powers by drinking fruit smoothies (one with x-ray and telescopic vision, one with super strength and one with flight) and are given gadgets by a former secret agent to battle a world domination obsessed Mad Scientist (who happens to be the father of their Alpha Bitch school rival), was made as a pilot. The series was not picked up.
  • The Pixar Short Air Mater actually appears to be this to the spinoff film Planes.
  • The Grim Adventures of Billy & Mandy:
    • The Grand Finale Big Damn Movie "Underfist" was very obviously trying to phase out the titular trio to cast focus on the otherwise minor characters that composed Underfist, but it never got off the ground, allegedly due to being Screwed by the Network, which didn't air the special again for years afterward.
    • When the show was still known as "Grim & Evil," and featured Evil Con Carne shorts, one episode featured the character Max Courage and his family in what was apparently intended to be the pilot for a spin-off that never materialized.
  • Wonder Pets had an episode featuring Ming-Ming visiting a cousin of hers that was a poorly disguised pilot for a possible spin-off series with Ming-Ming as the lead character, but said spin-off was never made.
  • Ben 10: Omniverse put the characters of Gwen and Kevin on a bus, but three episodes focused on how they were doing at Gwen's college. Those episodes gave Gwen a new superhero identity (Lucky Girl, a revamp of an old alias from the original series), supporting cast members like Professor Xagliv and a reformed Hex, stuck Charmcaster in a position where Gwen says she can also reform and become a friend, and set the evil alien turtle Adwaita loose to become a potential Big Bad to Gwen. Word of God is that these episodes could be spun off into a Lucky Girl show for CN Asia (where Gwen is immensley popular), though it hasn't happened yet.
  • Given the theme song is entirely about the Boo Brothers, with Scooby-Doo hardly mentioned, it's hard to believe that Scooby-Doo Meets the Boo Brothers wasn't intended as a pilot for a Boo Brothers series.
  • Tiny Toon Adventures had several, notably the episodes with Elmyra's family.
    • The first one introduced us to Mr. Skullhead, as the subject of Elmyra's imaginary TV show. He went on to become a recurring character in Animaniacs.
    • Elmyra ended up starring in another show anyway, but her family (and even Furrball) got left out of it.
    • "Fields of Honey" and "Two-Tone Town" were also suspected of being this; the latter even lampshades the show's eventual replacement (with "ACME Oop!", a.k.a Animaniacs).
  • Speaking of Animaniacs, "Spellbound" gave Pinky and the Brain a full half-hour story before getting their own show.
  • Secret Mountain Fort Awesome has the episode "Uncle Grandpa" nearing the end of its run, starring a completely different cast and only brief appearances from the main characters. Eventually, Uncle Grandpa was greenlit for its own series. As a side-note, Uncle Grandpa was the star of the pilot the show was based on, before a tremendous Re Tool; the Disgustoids only had a brief appearance and were seemingly mindless monsters.
  • Superman: The Animated Series had "In Brightest Day", an episode that focused primarily on the origin of Green Lantern, and did a pretty good job of establishing his mythology and arch-enemy Sinestro. Superman was a secondary character at most, and a victim of The Worf Effect. Ultimately, though, no new GL show came of it and when Justice League came along, the main Lantern was John Stewart. This episode remains Kyle Rayner's only animated appearance, if we don't count a few tiny cameos in JLU.
  • The "Doof 101" episode of Phineas and Ferb is so obviously this, with all the focus on Doof, Vanessa and Perry and only a brief glimpse of the title characters, plus the fact that it had its own theme song, no running gags, and an inexplicable subplot about talking bugs.
  • The Henry and June Show, a half-hour KaBlam! special, was produced in hopes of spinning KaBlam! hosts Henry and June off into their own series and premiered in Summer 1999 (around the same time Nickelodeon started using the duo as hosts for various programming blocks, replacing Stick Stickly). Due to low ratings, the spin-off never happened and the special was never aired again.
  • Street Sharks has an example that's like an odd cross between this and a Re Tool. It introduced a trio of evil velociraptor-like aliens from outer space in "Ancient Sharkonauts," and introduced their counterparts, the heroic Dino Vengers, in the following episode, "Sharkotic Reaction." The dinosaurs then proceeded to stick around for the next six episodes, which, as it turns out, were the FINAL six episodes of the series. The opening title sequence even changed to call the show Dino Vengers Featuring Street Sharks in the original airings. This resulted in the Dino Vengers and raptors, heavily retooled and having cut continuity with Street Sharks, getting their own show the next year: Extreme Dinosaurs.

Alternative Title(s):

Backdoor Pilot, Thinly Disguised Pilot
