The males and females are equally competent. Or incompetent.
There are all kinds of people, with their fair share of forte and flaws.
"A lot of girls watch this show! Let's make the female lead the only competent one."
"We'll get in trouble if the token character is in any way, shape, or form a bad person, or not, in some way, superior to the generic white male. Let's make Alice the most competent and the rest of them incompetent, for they are, after all, white males."
Lampshaded: "Alice is both the only girl in our group and the only competent one. But I'm sure it's just a coincidence."
Invoked: Alice works hard on becoming highly skilled and competent.
Exploited: Bob takes a lot of breaks knowing that Alice could cover him easily.
Defied: When Bob sees that Alice is showing him up, he starts training and working hard himself.
Discussed: "Why did you just assume I was better than my white teammates? As far as I can tell, we're all equally competent and equally heroic."
"Ever notice how it's always the girls and the minorities who win most of the battles, particularly against the white guys?"
"Okay, here comes the rescue scene. 2 to 1 odds it's Alice saving the guys again."
Implied: Alice was never being shown fighting, but she flaunted how her could fight better than the guys.
Deconstructed: Alice decides to leave the team because she's far more competent than the rest of them.
Reconstructed: ...But she comes back because she needed them as much as they did her, even if it's just so she'd have people to entertain her since she's so much better than the rest of them.
Played For Laughs: When Alice (dressed in the girliest clothes imaginable) enters, a glowing halo of light and sparkles surround her along with a bunch of roses ala Revolutionary Girl Utena.
Played For Drama: Alice dies, and because the men are hopelessly incompetent, The Bad Guy Wins.
