Angel: In the third season, Fred was added to the cast of three guys (Angel, Wesley, and Gunn) and one girl (Cordelia). Cordelia was The Heart of the group, Fred was The Smart Guy. Although considering Wesley was already used mostly for his brain, Fred's role could be seen as primarily to act as the Damsel in Distress that Cordelia could no longer realistically fulfill. Therefore playing this trope straight. Of course, this only lasted a season, and then more men were added.
Arrow has this in season two with Team Arrow containing Felicity Smoak (The Smart Guy) and Sara Lance (who is a combination of The Heart and The Big Guy).
Blake's 7 was an example at a time when The Squadette was still the expected trope. There are always two female members of the Seven — Jenna and Cally, then Cally and Dayna, then Dayna and Soolin.
Blue Heelers: This was the usual pattern from season 3 to 11 (not counting Chris, the civilian owner of the local pub): one female junior Constable (Dash, Jo, Susie, and Kelly) and one Senior Constable/Acting Sergeant/Sergeant (Maggie, Tess, Jo, and Susie), each effectively partnered with a male officer of similar rank. The pattern was broken with the introduction of Amy Fox, a detective who became PJ's partner.
Season 3 reveals that Payback, Vought's previous elite superhero team before the Seven, had two female members on it, in the form of Crimson Countess and Tessa from the TNT Twins.
The Boys initially have Kimiko as their sole female member. Beginning in season 2, Hughie's girlfriend Starlight becomes a clandestine member of the team, and she eventually becomes a full-time member at the end of season 3 upon quitting Vought.
The Seven has two female members at the start of season 1, with longtime member Queen Maeve being joined by newcomer Starlight. This appears to be invoked, as Starlight mentions that Vought is auditioning "girls" nationwide in search of Lamplighter's replacement, suggesting that the company's marketing decided to get with the times in terms of female representation. The trope is temporarily broken in season 2 when Stan Edgar appoints Stormfront to the Seven as a replacement for Translucent, with Vought's marketers naturally playing this up to score diversity points. This lasts up until Stormfront is exposed as a Nazi and is subsequently maimed by Homelander's son, forcing Vought to swiftly drop her.
Breakout Kings: Julianne (Mission Control), and con Erica, (with Shea, Roy, Lloyd, and Charlie make up the complete group of six)
Brooklyn Nine-Nine: Rosa and Amy are the only two female detectives on the squad (compared to the five men on the squad plus Chief Holt), although Gina (Holt's assistant) keeps the main cast from having this applied as well. Lampshaded in "The Sash":
Rosa: Well you're not the only girl at the table anymore. We work at a police force full of dudes. We gotta have each other's backs, OK?
Amy: You saying you have my back?
Rosa: Yeah, I got your back. Don't smile; I'm still mad at you.
Amy: I thought we were having a moment.
Rosa: Moment's over. Shut up.
Played straight in Season Six and onward after Gina quits her job in the Nine—Nine.
Buffy the Vampire Slayer: For the start of the fourth season, Buffy and Willow were the only female members of the Scooby gang. By the end of the season, however, both Anya and Tara had joined the gang.
CSI: For the first eight seasons, Catherine and Sara were the only girls on the team. When Sara left, she was replaced by Riley, and then rejoined the team. Subverted in season 12, when Morgan and later Finn joined the team.
CSI: NY always had two women on the team: Stella and Aiden from the backdoor pilot thru the 2nd episode of season 2, Stella and Lindsay from episode 2.03 thru the end of season 6, Jo and Lindsay for the final three seasons.
Dexter: Debra and Maria LaGuerta are the only women in a predominantly male workplace.
Dragons' Den (UK) with the introduction of Hilary Devey in series 9.
The Flash (2014): Iris West and Caitlin Snow are the only female members of Team Flash until Jesse Quick joins in Season 2. The two, however, were the only prominent female characters during the first season, and that's not taking into account that Iris only joined The Teamnear the end of it.
Fraggle Rock: The Fraggle Five have two female members, Mokey and Red, along with three boys, Gobo, Wembley, and Boober.
Freaks and Geeks: Lindsay and Kim among the five title freaks (the three geeks are all boys). Kim was added slightly too late to be billed as a series regular, but that was red tape.
Friends: Pre-series there were five of them with Monica and Phoebe being the only girls. However, Rachel arrives in the opening episode, making it a Gender-Equal Ensemble.
Fringe: Astrid and Olivia (the males Peter, Walter, and Broyles, complete the group of five)
House Stark has multiple examples. Sansa and Arya are the only daughters of Ned and Catelyn. Catelyn and Talisa were the only prominent women in Robb's forces. During Rickard Stark's reign, his wife and daughter Lyanna were the only prominent female Starks. During Jon's reign, he initially had three prominent female allies: Sansa, Brienne, and Mellisandre. However, he ultimately exiled Melissandre thus playing this trope straight.
Lady and Nymeria are the only females of the six direwolves, appropriately corresponding with the number of Stark girls.
Cersei and Myrcella were the only female members of the Royal Family during Robert's reign. Likewise, his brother Stannis has his wife Selyse and daughter Shireen (not counting his Sexy PriestDark Mistress Melissandre). Their youngest brother Renly also had Margaery and Brienne as the only female members during his campaign for the throne (Catelyn doesn't count since she's there to negotiate an alliance).
House Tyrell has Olenna and Margaery.
The previous generation of House Tully only had Catelyn and Lysa since their Missing Mom died when they were really young.
Throughout Season 3, Team Bran has Osha and Meera along with of course Bran, Rickon, Hodor, Jojen, and the two male direwolves of the Stark boys.
Daenerys and Missandei are this for Daenerys's court in the Slaver's Bay subplot. Yara Greyjoy, Olenna Tyrell, Ellaria Sand, and the Sand Snakes gradually join them in the final two episodes of Season 6, only to be sequentially dispatched off during Season 7.
House: While House's team follows The Smurfette Principle as strictly as can be, the overall show always has two women: Cuddy and a female duckling who is pretty much interchangeable. In the final season, Foreman replaces Cuddy but House's team gains two new women: Adams and Park.
Inverted on House of Anubis with the original Sibuna made of 2 guys and 3 girls. In season 3, however, it's played straight as Patricia and KT become the two girls on the team. Also works for Team Evil, who (Ammit not included), in terms of the original sinners along with Victor and Robert, have Denby and Patricia as the only two girls on the team.
How I Met Your Mother has Robin and Lily (the remainder of the five-man band being Barney, Marshall, and Ted.)
Kamen Rider Ex-Aid: Poppy Pipopapo and Nico Saiba are the only two female Riders among the CR Kamen Riders (although the latter is technically a Ride-Player rather than a Rider).
Towards the end of Kamen Rider Saber, Sophia becomes the fourth Kamen Rider Calibur, becoming one of two female Kamen Riders in the Sword of Logos alongside Reika Shindai/Kamen Rider Sabela.
Midway through Kamen Rider Revice, Hana Natsuki joins Weekend and gains her own Driver not long after, giving Weekend two female Kamen Riders with her and Sakura.
Legends of the Superheroes: Huntress and Black Canary are the only two female members of this continuity's Justice League (Wonder Woman was off-limits because her television show was airing on CBS rather than NBC).
Legends of Tomorrow started out following the trope to the letter, with the "two girls" being Kendra and Sara, on a team with seven boys. Kendra was written out at the end of Season 1, but Season 2 almost immediately introduced Amaya to take her place. This trope was broken in Season 3 when Zari joined the team, and by Season 4 it had become a Gender-Equal Ensemble.
Leverage features this with Parker and Sophie. When Sophie briefly leaves in season 2, she sends her friend and fellow grifter Tara to be the team's grifter in her place.
The Mentalist has Teresa Lisbon and Grace Van Pelt. Lisbon is even the team leader, but not the protagonist.
Misfits: Kelly and Alisha during the first three series, then replaced by Jess (who serves as the lone female cast member for most of series 4) and Abbey.
NCIS: Abby and Kate in seasons 1 & 2, then Abby and Ziva in later seasons, and then Abby and Bishop. Of course, for a while, there was also Director Jenny Shepherd.
New Girl: Jess and Cece among Nick, Schmidt, and Coach and/or Winston.
In Once Upon a Time Snow White and Red Riding Hood were the only prominent women fighting in the war against Regina. Although Granny is quite handy with a crossbow (yes, really), it's never said whether she was involved in the fighting.
The Outer Limits (1995): In "Abduction" Dianelle and Brianna are the two girls of the five-student group.
Primeval: The team rarely has more than two female members, rotating with Abby Maitland. The first season has Claudia Brown as the other, and a disruption in the time travel means that she's retconned out of existence by Season 2 and replaced with a reporter called Jenny Lewis (who otherwise is her complete doppelganger). Season 3 sees a third woman joining the team in Sarah Page...and Jenny then leaves halfway through the season to keep it at two once again. Between Seasons 3 and 4, Sarah is killed trying to rescue Abby and Connor from the Cretaceous Period, and the team has tech genius Jess as the second female. The same season does add an Action Girl in Emily halfway through, but since Jess stays in the ARC and Emily and Abby are the only two women in the field, it still fits.
Sherlock: For the first two series, Mrs. Hudson and Molly Hooper served as this to the main cast of protagonists, also consisting of Sherlock Holmes, John Watson, Greg Lestrade, and Mycroft Holmes. Series 3 added Mary Morstan/Watson, John's fiancee/wife, bringing it up to three girls to the team.
The two female members of the Jukebox Band from Shining Time Station are Didi the Drummer and Grace the Bass.
Silicon Valley: In the first season, Monica is the only female involved in Pied Piper's day-to-day operations. In the second season, Pied Piper hires its second female employee, and only female engineer, Carla, who lampshades this early on: "One thing worse than being the only woman in a company is being one of only two... Everybody puts this super-weird pressure on you to be friends."
Spartacus: Blood and Sand: Somewhat justified in that Spartacus's rebellion at the end of Season 1 consists of gladiators and house slaves, and any females among them were untrained in combat. Still, Vengeance has Mira training to fight, and they recruit another Action Girl from the German prisoners in Saxa. Mira is killed in the season finale, around the same time Naevia trains to fight, meaning Spartacus's forces again have two Action Girls by War of the Damned.
Stargate Atlantis for the majority of its run: In Season 1 - 3: Teyla and Elizabeth, in Season 4: Teyla and Sam, in Season 5: Teyla and Jennifer.
Season 4 actually had three girls: Teyla, Sam, and Jennifer.
The original Stargate SG-1 had this in season 10 with Vala and Sam. A case could also be made for recurring character Dr. Janet Fraiser being the second girl to Sam for most of the series- although she rarely accompanied SG-1 on missions off-world, she was a fairly consistent presence in the episodes set on Earth.
For most of Star Trek: The Original Series, there were two women in the core cast: Lt. Uhura and Nurse Chapel. Initially, Yeoman Rand was part of the cast as well, but the actress was let go in the middle of the first season. Only one episode ("The Naked Time") features all three women; Nurse Chapel and Yeoman Rand never interact with each other, but Uhura seems to be on fairly good terms with both of them.
Star Trek: The Next Generation has Deanna Troi and Beverly Crusher, after Tasha's death. Both had maternal and supportive roles, being the ship's head counselor and Chief Medical Officer respectively, but Troi was more exotic while Crusher was more of a down-to-earth character.
Star Trek: Deep Space Nine has Kira and Jadzia, contrasting Kira's emotional performances with Jadzia's much more grounded and calm nature.
When Jadzia died and they had to come up with a new Dax, it was decided early on that the new Dax would have to be female, so Kira wouldn't be the only girl.
Averted in Star Trek: Voyager because it had the first female captain as a main character, so there were three women in the cast: Captain Janeway, B'Elanna Torres, and Kes. When Kes left, she was replaced by Seven of Nine.
Star Trek: Enterprise has T'Pol and Hoshi, the experienced and emotionless Vulcan officer and (initially) nervous rookie communications specialist. Interestingly, as T'Pol learns to embrace her emotions more as she spends more time around humans, Hoshi becomes much more adept at dealing with her own fears and doubts as the mission progresses.
Star Trek: Strange New Worlds averts the trope by having more female main cast members than male ones including Una, La'an, Ortegas, Uhura and Chapel in the first season and adding Pelia in the second. There only four main male characters with Pike, Spock, M'Benga and Hemmer but George Kirk appears often.
Shows in both the Super Sentai and Power Rangers franchises have featured two female rangers instead of just one depending on the year. Super Sentai in particular have started featuring two female rangers on each team since its 1984 incarnation Choudenshi Bioman, with periods where the franchise would switch back and forth between having just one female ranger per team (1988-1989, 1992-1994 and 1998-2003) and then going back to having two girls again (1990-1991, 1995-1997 and almost all the current teams since 2004). Usually the two girls will wear Pink & Yellow, but other pairings have been used as well such as Pink & White (done twice), White & Blue (also done twice), Pink & Green (also done twice) and Blue & Pink.
Power Rangers would try to enforce this trope in its early incarnations by switching the gender of the yellow ranger if the Super Sentai counterpart was male. In fact, the Yellow Ranger from Mighty Morphin' Power Rangers was based on the male Tiger Ranger from Zyuranger, while four later Yellows (namely the ones in Lost Galaxy, Lightspeed Rescue, Time Force and Wild Force) all had male counterparts in Super Sentai. No genders were changed for Ninja Storm and Dino Thunder, since those teams started with three Rangers instead of the usual five and none of the extra rangers were androgynous enough to get away with converting any of them into females.
It was pretty obvious when they made English-language footage for the characters out of costume and then used the Japanese battle footage. For some reason, Trini in ranger mode didn't have a little skirt like Kimberly did. Or breasts, for that matter.
Gekiranger is the only team that had only one female ranger since the tradition of two female rangers per team was brought back to Sentai. However, a female villain named Mele switches sides during the final story arc and helps out the heroes, providing the show with a second heroine of sort. This was naturally carried over to Jungle Fury since the gender-switching practice was abandoned by that point.
In Go-onger/RPM, the second female ranger was not a starting member, but an extra ranger who joins the team mid-series with her twin brother, giving us another unusual color combination for the female rangers (Yellow and Silver).
Kyoryuger has it similar to the above, except the extra ranger in this case is not the main sixth ranger, and is violet in colour. Much later in the series a cyan female replaces a male ranger.
In Toei's official unofficial parody Hikonin Sentai Akibaranger, Blue and Yellow are girls, out of the three-person team.
In the non-Toei produced homage to Sentai, Kanpai Senshi After V, though Pink starts out as the only girl on the team of five, she is joined by a new female Yellow when the older male Yellow has to resign, reflecting the change in tradition in Super Sentai.
Averted in Power Rangers Dino Charge, which features the main 5-Ranger team with one female for the first time.
Played straight in the 2017 series Uchu Sentai Kyuranger, which features a whopping NINE rangers, only two of whom are female: Raptor 283 (Pink) and Hami (Green). The ratio gets even worse when THREE additions join the already larger-than-usual team, and none of them are female.
This also tends to be the rule among villain factions in the series as well. Usually they'll have, if not just one, two female executives in their ranks. Exceptions to this include the Vader Clan in Denshi Sentai Denziman (which had three, including the Big Bad), Machine Empire Black Magma in Taiyou Sentai Sun Vulcan (which by the end had five female members as opposed to just two male ones, inverting this into "Two Guys to a Team") and the Youkai Army Corps in Ninja Sentai Kakuranger, with the five-woman "Flowery Kunoichi Team".
Teen Wolf began with Allison and Lydia as the main cast's sole females, with four males (Scott, Stiles, Derek, and Jackson.) However, there are many significant female characters amongst the supporting cast, although still fewer than the men. After some changes within the team through the seasons, however, the team had a Gender-Equal Ensemble in season 4 (Lydia, Malia, and Kira for girls; Scott, Stiles, and Derek for guys). In season five it became unequal again with Liam's Promotion to Opening Titles, though the three girls still remain.
The core gang of six in That '70s Show has Donna and Jackie as the two females while the remaining four are male. (Eric, Hyde, Kelso, and Fez.)
The first and second series of Torchwood has Toshiko and Gwen as the two women to a Five-Man Band.
The first example is Yuko Minami and Noriko Mikawa from Ultraman Ace, who are especially notable because Minami was the female co-host of Ultraman Ace while Mikawa was the team's second-in-command instead of just being a simple Bridge Bunny. This unfortunately ends once Minami is Put on a Bus as viewers couldn't accept the idea of a female Ultraman host at the time.
Megumi Iruma and Rena Yanase of GUTS from Ultraman Tiga with the former as the first female captain of the franchise. They were succeeded in Sequel SeriesUltraman Dyna by Ryo Yumimura and Mai Midorikawa, who form a respective Tomboy and Girly Girl dynamic.
Satomi Hayakawa and Rumi Honjou in Ultraseven '90s direct-to-video episodes.
While Ultraman Gaia has the all-female Team Crow squadron, XIG's base operation crew has Atsuko Sasaki and Georgie Leland. Ayaka Ukai occasionally replaces one or the other.
Deputy Captain Mizuki Shinobu and Ayano Morimoto in Ultraman Cosmos' Team EYES.
Nagi Saijyo and Shiori Hiraki of the Night Raiders in Ultraman Nexus.
Raiha Toba and Moa Aizaki in Ultraman Geed. Although they aren't the part of the same team, they usually fight side by side with each other for the benefit of their mutual friend Riku.
