'''Basic Trope''': A fighter in full armor or some other form of gender-masking attire is revealed to be female.
* '''Straight''': Bob is saved by a warrior wearing a full suit of armor. The warrior is revealed to be Alice when she takes her helmet off.
* '''Exaggerated''':
** The armored warrior appears to be the pinnacle of masculinity. Underneath the armor is Alice, an incredibly feminine woman.
** It isn't revealed that Alice is a woman until the very end of the last episode.
* '''Downplayed''': Bob is saved by one of a clan of ninja. He only finds out the identity later, much less the fact that it's Alice, a female.
* '''Justified''': Alice's armor suit is either designed for men or designed in a very unisex manner.
* '''Inverted''':
** A warrior in very sleek, feminine-looking armor takes off their helmet. Inside the suit is Bob.
** We're led to believe that TheHero is out to SaveThePrincess, but when he finally pulls off the rescue, we see him rescue Prince Bob.
** Alice, the boyish-looking ActionGirl, is revealed to have once been the famous hero Albert, having pulled a SweetPollyOliver to join the then all-male hero team, before eventually disappearing for some reason (and, obviously, resurfacing just in time for the team's membership to be opened to females as well).
* '''Subverted''':
** "Alice" later reveals himself to be an [[DudeLooksLikeALady effeminate man]] named Alex.
** Alice is RobotGirl or HumanoidAlien.
* '''Double Subverted''':
** "Alex" is then revealed to be a SweetPollyOliver pulled by Alice in order to get the armor in the first place.
** Even if Alice is not human, she is still technically female.
* '''Parodied''':
** Alice's "gender-concealing" armor is nothing more than a hat or a set of eyewear. Before the reveal, she is treated like a man despite obviously looking like a woman.
** Alice mannerisms and speech ([[VocalDissonance even if it's muffled]] by the suit) are [[{{Kawaiiko}} incredibly girlish]]. Yet, everyone gets shocked when she removes the armor for the first time.
* '''Zig Zagged''': Alice has different sets of armor that may or may not hide her gender. Also, she is a {{Bifauxnen}} underneath and fools some people but not others.
* '''Averted''':
** Alice's gender is made known to the viewers before she starts kicking butt in a suit of armor.
** Alice's gender can be recognized by her armor.
** The warrior never takes off its helmet.
* '''Enforced''': ???
* '''Lampshaded''':
** "Wait, you're a girl?!"
** "What do I have to do, put pretty pink ribbons on the chainguns? YES, I'M A GIRL! GET OVER IT!"
* '''Invoked''': [[YouGoGirl Alice's peers are sexist, so she disguises herself in a bulky suit of armor, kicks ass, then intentionally reveals herself in order to prove a point.]]
* '''Exploited''': [[BigBad Empress Evulz]]'s attack on what was presumably an all-male group utilizes [[AppliedPhlebotinum some substance]] that targets the Y-chromosome. Alice, inside the power armor and not having a Y-chromosome, [[PlayingPossum pretends to be afflicted]] so that when Empress Evulz's forces pass her not-dead body, she gets up and pours a ton of rounds into their backs.
* '''Defied''': Alice deliberately uses one of the aversions of this trope to make sure that nobody mistakes her for a guy.
* '''Discussed''': "Hey, wouldn't it be hilarious if that big armored guy over there turned out to be a girl?"
* '''Conversed''': "This is one of those moments where a tough guy swoops in, saves the day...and turns out to be a girl."
* '''Plotted A Good Waste''': The author thinks the book needs GirlsNeedRoleModels.
* '''Deconstructed''': Alice has never before been seen without her armor, thus does all her work with everyone under the assumption she is a man. After TheReveal, the supporting characters take her less seriously, and feel she is "less up for the task" while ignoring her previous achievements to the contrary.
* '''Reconstructed''': Alice proves herself as a much more than capable warrior in a TakeThat to the men who doubted her.
* '''Played For Laughs''': Alice's armor even changes her voice... When she's in her armor, she speaks with BassoProfundo.
* '''Played For Drama''': Alice is a seemingly-insignificant [[ChekhovsGunman background character on Bob's side]], and at the same time a MysteriousProtector who saves Bob's life at the most hopeless moments and is shown to have ties to TheOmniscientCouncilOfVagueness. The entire story builds up to TheReveal of Alice's identity, motives... and the fact that she's a woman.
Wait a minute, {{Samus Is A Girl}}?
