Basic Trope: There's only one (important) female main character, and she (usually) exists solely to appeal to the female demographic.
- Straight: Amy the Amazing Girl is the only female member of her Super Team.
- Exaggerated:
- Amy is the only female character in her respective medium, let alone her Super Team.
- The team decides they need more members and expands to 108 superheroes... but Amy is still the only female.
- The team has no female character at all and the show was thought to be a case of Chromosome Casting, until it's revealed that Emperor Evulz is a girl.
- There's little to no female character at all, the only thing considered "female" on screen is an Eldritch Abomination.
- Amy is the only female citizen in a whole One-Gender Race country.
- Downplayed:
- Amy is the only female member of her Super Team, but there are lots of Badass Normal Recurring Characters who are female; they're just not official members of the team.
- Two Girls to a Team
- Two Guys and a Girl
- Justified:
- The story takes place in a time period where women were considered less capable of being badass than men, so the team is actually being very progressive by including Amazing Girl at all.
- Other girls were offered a place on the team, but only Amazing Girl accepted/qualified.
- Amy is the sole survivor of a gendercide.
- The story is set in a place that doesn't allow women and Amy is either a Sweet Polly Oliver or the first/only woman who is allowed to enter.
- Amy is transgender, and the team is her old circle of bros with whom she still hangs out.
- Inverted: Andrew the Awesome Man is the only male member of his Super Team.
- Subverted:
- Everyone thinks Amazing Girl is the only female, until the Slaughterinator turns out to be a woman disguised as a man.
- Amy starts off as the only female on the team, but later on, Chica joins the group.
- "Amy" takes off "her" dress and wig, revealing "herself" to be Adam, a guy.
- Doubly Subverted:
- The Slaughterinator is actually a man who was transformed into a woman via Applied Phlebotinum.
- After the Slaughterinator is revealed to be a woman, Amazing Girl is revealed to be a man.
- But not long after Chica joins, Amazing Girl is Killed Off for Real.
- Amy is Recursive Crossdressing, and she needed to pretend to be a guy for a mission.
- Alternately, Adam is a Tomboy who unwillingly wears dress and wig.
- Parodied: Every time it seems like another woman is going to join the team, they get literally Stuffed into the Fridge by the end of the episode.
- Zig Zagged: Amazing Girl is the only female member of her Super Team until she gets turned into Awesome Man. Then it's revealed that the Slaughterinator is a woman disguised as a man. Then Doctor Killblood zaps the team with the Phlebotinumitizer 3000, turning all of them into women, except for Awesome Man who is now the only man... at least until Doctor Killblood's son switches sides and joins the team.
- Averted:
- The Super Team has an even gender ratio.
- The Super Team is formed by either entirely men or entirely women.
- Gender Is No Object, for a large-scale aversion.
- The team's gender is never revealed at all or neither male nor female.
- Enforced:
- The show's Target Audience is adult men, yet at the same time, the creators don't want to come under fire from feminist movements for having an all male cast, or they want to receive wider demographic further than adult men.
- The show's main Target Audience is Yaoi Fangirl, but the creators add one female character because they want to receive Multiple Demographic Appeal and avoid the Girl and Queer Show Ghetto.
- The work was created in the days when there wasn't such great equality, so it didn't age well, Values Dissonance and all.
- The work is an amateur no-budget production where all the characters are played by the author's friends, and he only has one female friend who agreed to participate.
- Lampshaded: "Amy the Amazing? Yeah, she's our token chick."
- Invoked:
- The team consists entirely of men, until they let Amazing Girl join them to avoid being criticized by Straw Feminists.
- Amazing Girl prevents other female characters from joining the team and taking her position.
- Exploited:
- Amazing Girl uses her status as the sole female character to hook up with whomever she likes.
- Starring Smurfette
- Defied:
- The team gets Madam Mysterious and Professor Pink to join them because Amazing Girl doesn't want to be the only female member in the team.
- Amazing Girl chooses to join the Amazon Brigade instead of an entirely male team.
- Discussed:Amazing Girl: Being surrounded by men all the time SUCKS!
Professor Pink: Look on the bright side, if this were a comic book there'd only be one of us. - Conversed: "Have you ever noticed how in comics there's never more than one woman per Super Team?"
- Implied: The team is made up by entirely men and one Ambiguous Gender character.
- Played For Drama:
- Amazing Girl's relationship with the Super Team is on the rocks due to Amazing Girl feeling alone in the team and her not having anyone to talk to about her issues.
- The extra horny Super Team only took Amazing Girl on so they'd have something to ogle at.
- Deconstructed: Everyone else on the team treats Amazing Girl differently because she's the only female. Eventually, she gets sick of it and quits the team, or even worse, switches sides.
- Reconstructed: The Super Team only lets in the badassest of the badass to maintain its Badass Crew status, and so far, they haven't found any women as badass as Amazing Girl.
- Intended Audience Reaction: The members of the Super Team turn out to have some (conscious or not) prejudice against girls, and getting over it by accepting that times change and switching to gender-equality policy is a significant part of their Character Development.
Go back to The Smurfette Principle... But don't bring more than one woman with you! Girls Have Cooties, you know!
