Bifauxnen / Video Games

• Jess from Advance Wars has a buzzcut and wears a military uniform with pants. If not for her name and some *slight* bumps in the chest region, she'd be indistinguishable from a male. The second game enhances this effect my making her carry around a somewhat phallic-looking tank shell.
• Assassin's Creed IV: Black Flag: The character first known as "James Kidd", and actually named "Mary Read" is quite clearly voiced by a woman, and is revealed to be one midway through the game.
• Atelier Annie: Annie is practically the embodiment of this trope. Seriously, look at this and see what your reaction is... If the existing image wasn't so good, she'd be the banner girl for the trope. Of course the game itself wastes no time in poking fun at her for this, with several NPCs mistaking her for a boy at first glance.
• Bloodline Champions has the Nomad bloodline's Officer outfit. There's has cleavage on her, but otherwise looks very androgynous. There's a piercing under her lip which one could mistake for a soul patch.
• In Digimon Story: Cyber Sleuth, The Ace hacker Yuugo is revealed to actually be his younger sister Yuuko masquerading as him while in he's in a coma.
• Final Fantasy:
  • Faris, the pirate captain in Final Fantasy V, whom Bartz and Galuf swoon over before The Reveal. This◊ is what Amano originally drew her as. The SNES's graphics messed the twist up. (Except for fans who assumed that the pretty, long-haired man was one of the series' many Long Haired Pretty Boys.)
  • Lightning from Final Fantasy XIII generally doesn't qualify due to her obviously feminine appearance in the game... however, she later pose for a fashion magazine... men's fashion magazine, that is. In the third game in her series, she can wear men's suits, and gets mistaken for a prince in the NPC chatter.
• Fire Emblem: Awakening:
  • Marth, or better said, Chrom's daughter Princess Lucina.
    Chrom: Wait, You're- You're a woman?
    "Marth" aka Lucina: And quite the actress too. Honestly, I'm surprised you didn't figure it out until just now.
  • A Female Avatar can be given bifauxnen looks if the player uses the right build and hairstyle combination.
  • A Female Morgan. It makes sense since, depending on whether the Avatar is a man or a woman, Morgan can be either a guy or a girl. The main physical differences between a girl Morgan and her Distaff Counterpart are her finer features and her sliiiightly longer hair.
• Halo: The "tough" type female Marines (including one voiced by Michelle Rodriguez in Halo 2), and Tedra Grant from Spartan Ops, all with short hair and figure-concealing armor. Kat from Halo: Reach borders on this, but her figure is noticeably more "feminine" than her squadmates, despite being in full armor 24/7.
• Miyako Yakumo from Harukanaru Toki no Naka de 5. She looks completely like a boy, dresses like one, fights like one and has an ambiguous voice to boot.
• Yuri from Harvest Moon: A New Beginning would probably be mistaken for a boy a lot more often if she wasn't introduced as Emma's daughter and one of the girls the male player character can marry. (She is also a secret bachelorette, meaning only those who go to sites that show all the potential candidates will know she is one.)
• Makoto Kikuchi from The Idolmaster was raised to be more like a boy by her father, who wanted a son, and thus she looks and acts very masculine out of habit. However, what she really wants is to be more feminine and get more attention from boys, so she became an Idol Singer to reinvent herself. Unfortunately for her, the majority of her fanbase In-Universe is made up of girls with crushes on her.
• From Infinite Undiscovery: Vic's true gender soon becomes fairly obvious, with several hints shortly after Vic joins your party.
• King from The King of Fighters. She dressed as a man in the original Art of Fighting, due to an incident regarding her gender and childhood training in Muay Thai (which back then didn't accept female practitioners), as well as being forced to be a bouncer by a local gang. In that game, she is presented as a male at first (besides baring her bra if beaten with a super move and having different dialogues when this happened), but future games acknowledge her as a woman who chooses to wear male clothes both for personal taste and practical reasons. She continues to dress in masculine clothing in almost all her later appearances; the closest concession, clothing-wise, is either wearing dresses in artwork and in her ending in The King of Fighters XI (and the last one is because she is in a date) or showing up in two-piece swimsuits in the Dating Sims.
• Ado from Kirby's Dream Land 3 has a boyish haircut and wears an artist's smock, which — combined with her low-detail sprite and androgynous name — makes her easy to mistake for a boy. Her counterpart in Kirby 64: The Crystal Shards, Adeleine, is more readily identifiable as a girl due to her different name, haircut, and outfit, but English speakers (including Nintendo Power) were still confused about Ado's gender until translated Japanese media confirmed that they're both girls.
• Another SNK example - Koujiro whom her name is actually Kaori, the Sweet Polly Oliver/Half Identical Twin of The Last Blade. Thanks to a gender-ambiguous name, her gender is debatable until her story-mode ending, when her supporting cast are relieved that she can go back to Staying In The Kitchen. Thankfully, she has other ideas.
• Love Nikki - Dress Up Queen plays around with the trope quite interestingly:
  • Kaja is a popular rock star from the Miraland world, popular with men and women alike, and owner of very boyish looks. She often challenges Nikki to duels that include very boyish clothes (often tagged "Unisex"), in order to broaden Nikki's style horizons.
  • Nikki herself is very much a Girly Girl, but Kaja's challenges will require her to dress up as a bifauxnen. Which can be a nasty surprise for new players, since "Unisex" clothes tend to be a bit hard to find among the sea of girly dresses, tops, coats, wigs, etc.
• Metal Gear Solid: Peace Walker has Dr Strangelove, with her short hair and androgynous tailored clothes.
• Jill from Mighty Jill Off. Even more so in her appearance in Super Meat Boy.
• Kumatora from Mother 3. A little kid mistakes her for a boy at one point. And the Magypsies.
• Until her more feminine design in Nuts & Bolts, Kazooie.
• Overwatch has a villainous example in Moira O'Deorain. She has short hair, a rather angular face, a slim build, and a low voice. But what really puts it over the edge are the shirt and tie she wears in her origin story video and in some of her sprays. And then her "Glam" and "Moon" skins are pretty much knock-offs of Ziggy Stardust, David Bowie's most Bishōnen stage persona.
• Perfect Dark: Joanna Dark in the original, less so in the XBLA rerelease.
• Persona 4:
  • One of the main characters, Naoto Shirogane, the masculine, pistol-wielding, uniform-wearing, amateur detective-turned high school student is a biological woman dressing as a man because she believes that she won't be taken seriously in a mostly male field of work. After her gender and identification are revealed, Naoto decides to keep the boyish looks and behavior — unless she's specifically asked otherwise by the Protagonist, and only when they are alone.
  • Izanami's human form looks a lot like the Protagonist, despite being a woman, and looks even more boyish in the manga.
• Pokémon Scarlet and Violet has Rika, who has broad shoulders and a flat chest, and wears suspenders with a collared shirt. She's easy to mistake for a young man if you miss the long ponytail behind her.
• Hikaru of Power Instinct Matrimelee, like many characters in the game, is a parody of common fighting game archetypes, and in particular of Bridget from Guilty Gear (who was initially written as a feminine guy before she was later confirmed to be a trans woman). Hikaru's gender is so well hidden that nothing in the game itself actually mentions it, not even in her ending. The only way someone would be able to determine her true gender is from other documentation.
• In SaGa Frontier, Asellus is a girl who is mistaken for a man by a maid who made a suit for her, who develops a crush on her. According to a sourcebook, this (and Asellus's feelings for her companion, Lady White Rose) is due to the magical blood transfusion she got from the Charm Lord, a Dracula-type character. (It doesn't help that the Lord insisted that Asellus become the "Prince" (not princess) of his kingdom.)
• Sakura Wars:
  • Maria Tachibana and Kanna Kirishima are tall and have husky voices, so they usually play male roles in their musical productions.
  • Later we get Leni Milchstrasse, who is petite and waifish and talks like a boy.
• Senran Kagura has Miyabi, who is this despite being well endowed in a World of Buxom. She gets mistaken for a boy frequently, to the point she has her own Instant Fan Club.
• South Park: The Fractured but Whole has a child variant. If you choose to make the New Kid a girl, the boys will comment on what a feminine-looking boy "he" is, how soft and smooth "his" skin and hair are for a boy, etc. They never actually manage to connect the dots, and the only party member who does, Call Girl, promises to keep the New Kid's true gender a secret.
• Splatoon 3: Shiver, with her loose-fitting shawl, sarashi, and androgynous appearance, can pass for a remarkably pretty young man; Nintendo had to explicitly clarify that she identifies as female due to Viewer Gender Confusion.
• Summon Night: Swordcraft Story: Razzy, a major supporting character in this game, is very ambiguously gendered (To characters anyways, she's first introduced as another character's "niece"). In fact, throughout a good chunk of the game, the player character and various NPCs think that Razzy is a boy. One NPC even comments that Razzy will be a handsome man when he grows up. Coupled with this boyish look is that, out of the five available weapons in the game (sword, axe, spear, knuckles, and drills), Razzy uses knuckles. Also adding confusion is that it is hinted that (read:Immediately starts addressing you as Onee-sama and directly wonders if two girls can get married), while playing as the female option, Pratty, Razzy will acquire a crush on you.
• Leo Kliessen from Tekken 6. Short hair, check. Masculine name, check. ^note Her full name is Eleonora, and "Leo" is a nickname Masculine outfit, big check (includes a white masculine tuxedo).
• Touhou Project:
  • Wriggle Nightbug, the only member of the massive cast with both short hair and pants, leading to a lot of Viewer Gender Confusion and subsequent jokes about other characters mistaking her for male.
  • Shou Toramaru, whose boyish name, appearance, and career caused more Viewer Gender Confusion.
  • Toyosatomimi no Miko, who's based on a real male historical figure and has a hefty dose of masculine arrogance, though she still wears a long skirt as part of her outfit.
  • An obligatory PC-98 example, Meira from Story of Eastern Wonderland, whose demands to fight Reimu for her powers were mistaken for a proposal by Reimu... and accepted. Meira clarifying her gender didn't help.
• Ione of Vanguard Bandits is more than a little manly in appearance to the player. This doesn't stop The Hero from complimenting her beauty anyway.
• Wario Land 4: Princess Shokora, whose appearance changes in the end cutscene depending on how many treasures you collected. In the 100% Completion ending (which presumably shows her true form), she could easily be mistaken for a prince.
• Xenoblade Chronicles 2 has this with Special Inquisitor Mòrag. Though this isn't typically mentioned much, Mòrag being The Stoic party member and having rather masculine attire, on top of her rather chiseled-yet-feminine facial features, makes her look rather Bishōnen-like, helped in part by the game's art style taking a more Animesque approach in comparison to Xenoblade Chronicles 1 and Xenoblade Chronicles X. This even manages to fool Tora at one point.
