Area no Kishi: When Kakeru played alongside his teammate Seven in elementary school football, he thought of her this way. He didn't start to notice Seven's more "girly" aspects until just before she had to transfer schools. When she transferred back in high school, however, the difference was quite obvious.
Berserk: A mercenary since her teen years, Casca has spent much of her life living and fighting with men as her only comrades. While she doesn't exactly hate feminine things, she's gotten used to wearing male clothing for convenience and feels more like she knows what she's doing when in a masculine environment. And although her enemies occasionally talk shit about her being a female soldier, the entire Band of the Hawk has nothing but respect for her.
Tatsuki Arisawa is Ichigo's classmate and childhood friend. She's studied Karate since childhood, which paid off when she was ranked the second strongest girl in Japan (in her age group). Tatsuki also used to protect Orihime from bullies, when they were youngernote Kids used to pick on Orihime because of her hair color and how long her hair was. So she used to cut it short, in hopes that they'd leave her alone. Tatsuki made them back off, by acting as Orihime's bodyguard, which is the reason Orihime grew her hair long - as a symbol of their friendship. After the timeskip, she part-times as an assistant instructor at a local dojo.
Sui-Feng is practically Tatsuki's shinigami separated at birth twin. They not only look alike, but they also have similar temperaments, each has a background in martial arts, and acted as bodyguards. However, Sui-Feng is an assassin and is currently Yoruichi's successor as both the head of division 2 and the Onmitsukido.
Kuukaku Shiba is Ganju's Cool Big Sis, and a Lad-ette all-in-one, who makes fireworks using the Shiba Family's special brand of gunpowder and kidou.
Bokura no Hentai: Miki only hung out with boys in elementary and has only brothers. She was a boyish girl who didn't "get" other girls until puberty hit, and suddenly her male friends were uncomfortable with her chest growth. Afterwards, she began hanging around girls and became girlier.
Dad, the Beard Gorilla and I. : Downplayed. Even though Michiru is a Tomboy who spends most of her play time with two guys, Yuta and Daichi, she does have one female friend, Kozue.
Digimon Tamers: Rika Nonaka is an Action Girl, is much more willing to fight than Takato or Henry, and has the title of "Digimon Queen" due to being extremely proficient in the Card Game.
Doraemon: Subverted with Shizuka. While she usually hangs out with a bunch of boys, she never joins them in their rough antics and always remains extremely feminine and graceful. In some episodes, she's also shown to have female friends.
Bulma has tomboyish traits and often shares common interests with her friends in the Dragon Ball Gang (and later, the Z Fighters). Her love for mechanics and gadgetry is a plus factor.
Later on there's Videl, who is a tomboyish martial artist and the only female on both the police force and later in the Tenkaichi Budokai.
Family Complex: Natsuru, the eldest daughter, is always playing soccer together with the boys, and her friends often forget that she's a girl. The fact that she's a Bifauxnen doesn't help.
Great Mazinger: Jun hung out with boys more often than with girls, liked bikes, and practiced martial arts.
Library War: Kasahara is established as the first woman to ever earn a spot on the Library Defense Force's elite division. She's shown to excel at Judo, as well as track and field events. During a hazing ritual, she was startled awake by an instructor disguised in a bear costume. She responded by dropping him with a single punch, which earned her the nickname "bear killer II"note since Dojou had done the exact same thing, years prior; making him the original "bear killer".
Love Lab: Riko Kurahashi is so tough and uninterested in feminine things that most boys don't register that she is a girl.
Usui: (deadpan) Azuki sempai... are you sewing...? Takeru: (snidely) Once again, trying to be a girl. Azuki: (offended) You have a problem!? What do you mean, being "like" a girl!!
Mazinger Z: Sayaka's hung out with boys ninety percent of the time, liked bikes right like them, and piloted Humongous Mecha right like several of them.
Miss Kobayashi's Dragon Maid: Kobayashi was a tomboy as a child, and continues to have a complete lack of interest in anything even remotely feminine as an adult (barring the occasional A-Cup Angst). Takiya even says that she's "just one of the guys around the office".
One Piece: This is apparently the kind of relationship Vivi had with Koza and the Suna Suna clan when they were kids. As a girl, Vivi didn´t have trouble fighting with boys of her age, and they also weren't afraid of giving the fight back.
Pokémon: The Series: Misty. Her sisters give her constant crap for not being girly enough, and since they're all airheads (in the dub, anyway, although Daisy later subverts it) she just kind of runs with it to distance herself from them. Usually seen competing with Ash in pretty much every open competition they come across, or cockblocking Brock.
Powerpuff Girls Z: Buttercup (known as Kaoru Matsubara in the original and Buttercup in the dub) is even more of a tomboy than the original western animation version. She is rarely seen wearing clothes that aren't knee-length shorts, a baseball cap, and a sports shirt. The only time she isn't wearing something like that was in a rabid imagination of Princess Morbucks or during her initial turn to her Powerpuff form where she wears a skirt, although the required skirt sent her into a mad rage which was only quelled by her breaking nearly everything. Additionally, the series makes it clear she loves sports, especially soccer, is rougher and rowdier than the other two girls (who refuse to partake in a few ventures due to their femininity), and nearly drives Ken to total exhaustion when she pretends to be his mother, which seems to entail waking him up early and forcing him to jog for a mile (much more akin to a father or a coach than a mother).
Queen's Blade: Elina is the Tomboy Princess (also Captain of the Royal Guard) of the Vance Family and is the youngest of her sisters. While all three are capable combatants, she's the only one who's had training in martial arts which is enhanced by her catlike speed and agility.
Ranma ½: As far as Ranma's concerned, Ukyō really is one of the guys. At least, he thought she was, back when they were kids. So he was shocked when he finally (as in years later) realized that she was really a girl the whole time. But he doesn't treat her any differently than he used to and mostly thinks of her as his oldest friend. Which is helped by the fact that she continues to refer to herself using the "boku wa" pronoun. Ranma does refer to her as his "cute" fiancee, but that's mostly a dig at Akane (his "uncute" fiancee).
Tomo-chan Is a Girl!: Tomo, the title character, is an athlete on par, if not superior to, any male of her age. Her best friend since childhood, Junichiro, legitimately thought she was a boy when they were children and seems unable to consciously acknowledge she is a girl. This is problematic for Tomo because she's in love with Jun and wants him to notice she's a girl.
UFO Robo Grendizer: Maria Fleed was the biggest offender of the female leads of the trilogy. Her first appearance consisted of her racing against her male friends (and in the next episode, her first scene featured her racing against Kouji and getting pissed when she realized he was giving her special treatment), and she was infamous by being a decidedly tomboyish Tsundere.
Variable Geo: Yuka and her best friend, Satomi, are the tomboy equivalents of Ryu and Kyo Kusanagi respectively. They studied martial arts together and grew up as sparring partners, so they've been competing against each other in full-contact, since childhood. As a result, both are athletic, highly skilled, and are recognized as two of the top contenders in the VG tournament.
The H-manga "When I Returned to My Hometown, My Childhood Friend was Broken" (Jimoto ni Kaettekitara Osananajimi ga Kowareteta) by Zyugoya is about a young man named Touma who returns to his hometown after college, and finds his tomboyish child friend Kyouko is now a sheepish and timid woman. The manga's primary focus from hereon is Kyouko's perspective and her coping with anxiety brought on by a group assault heavily implied to be rape that happened in College when Touma was away (and the trauma from the event caused her to drop out and isolate herself). The remainder of the story is Touma and Kyouko interacting, with her battling her trauma against her desire to reconnect, and Touma cheering her on as she improves herself and slowly finds ways to step forward (such as taking a part-time job to get out of the house). The story goes through numerous dates, an eventual engagement and marriage, pregnancy, birth, and then the two protagonists as parents to a tomboyish three-year-old daughter. Kyouko's past is shown numerous times to contrast against her current personality. She outright admits that she has never been particularly feminine, got into many fights, often argued about having to wear a skirt as part of her uniform (actively wearing men's shorts underneath in protest), and was never interested in what girls were doing. While this is still true to an extent in the present, her trauma has caused her to retreat from society, and her time with Touma has her actively begin pursuing stereotypical wife-like traits (such as cooking) in an effort to impress Touma (who just likes her as is). It also doubles as a panic trigger, as Kyouko didn't want to tell Touma about the rape due to the past image of her being a 'strong' girl, and believing it would be tarnished if Touma knew about it. Touma, being a supportive partner, believes she is still just as strong as before, and that things have changed, but Kyouko is the same underneath.
You're Under Arrest!: In addition to being freakishly strong, Natsume is well known around Bokuto Precinct for being a Big Eater and regularly engaging in arm wrestling contests with her fellow officers on her lunch break. It wasn't until Toukairin arrived at the station that someone could finally match her!
Anzu Mazaki / Tea Gardner is a tomboy who is the only girl in her group of friends. A running joke is that she states "I need more female friends" whenever she gets exasperated at the guys' antics.
Alexis from Yu-Gi-Oh! GX is more focused on the pro dueling circuit than the cute guys that other girls gossip about. It's not that she dislikes her peers, she just finds them harder to relate to than Jaden's gang. It doesn't help that their personalities are much more hyper than hers.
