She's also a bit of a subversion, as she's aware she has "issues" and is currently seeking professional help for them. (Even if she agreed to seek that help in order to avoid the other elephant in the room (Marten's feelings towards her))
Also lampshaded by a shirt with the word 'Tsundere' printed on the front which she occasionally wears. Interestingly, the shirt was a gift from Hanners, who wasn't entirely sure that Faye would understand the reference.
Dora is arguably a Type B herself, particularly as shown here when finding out that Marten had a girl flirt with him.
Hell, Type A is essentially the selling point of Coffee of Doom the coffee shop Dora owns, as its customers seem to enjoy being served by the tsuntsun Faye.
Who would have thought Hanners could be so Genre Savvy? [1]
Kate in Misfile alternates between this and Kuudere. She's not in love with the protagonist and treats him/her as a little sister. But Ash is still one of the three people in the comic who can draw out anything resembling deredere from Kate. We could assume she's softened up for Harry a little, since she acts as his secretary without complaint and eventually marries him. For the most part her face is blank now that her sister isn't haunting her, but the temper Kate had? All natural.
Aubrey started out as this in Something Positive, but she's gotten to the point where she uses words before her fists. She still has a sharp tongue though.
Gwynn from Sluggy Freelance. In almost all her relationships, not just the romantic one(s), although her friendships with other women can be a bit less like this.
Kada Jansen, too. Well, except for the part about friendships with other women, because the only other females in the "Oceans Unmoving" saga are either flashback-only characters or enemies.
Torg: Sasha's over here just about every day, curious why you're ignoring her. What am I supposed to tell her?
Riff: Whatever you want.
Torg: This is more than just a little creepy, Riff.
Riff: "Creepy?" Torg, it's about Gwynn!How do I explain to my current girlfriend that my ex-girlfriend, currently demon-possessed, is haunting my dreams and might be stopping by any day to collect all our souls?
Torg: No, that's not creepy. I was talking about Sasha. She isn't hurt or angry, just curious.
Hayasaka Erika from Megatokyo. She's bitter and sarcastic most of the time, and has occasional violent outbursts. When she first met Largo, she broke his arm. But when Largo shows he respects her for who she is, not the star she once was, the deredere comes out in full force.
Also Miho and Piro.
Miho generally hides it under scorn, but once you get past that she's stereotypical type A.
Piro is a bit of a weird one. He's nice to strangers, frustrated with Largo, and a type B with his girlfriend (though he's pretty good at keeping the tsuntsun from getting out of hand). When he's talking about/to Miho, however, he goes full Type A.
Lynda of Penny and Aggie, towards Rob, in the "Modern Maturity" arc which flashes back to their high school years. Justified in that Rob shows his affection by teasing and pranking her, provoking angry and even violent reactions. She begins to warm up to him when he reveals he has a caring and thoughtful side.
Lucy from Bittersweet Candy Bowl is a pretty excellent example of this until she finally admits to her feelings for Mike.
Actually, Lucy is a Deconstruction of the Tsundere trope. Her punching and striking Mike is not played for laughs, and Mike's reaction to this and the consequences of her behavior is arguably a realistic depiction of what a real, hard-core Tsundere would be like.
BLU Scout from the Team Fortress 2 webcomic Cuanta Vida. His relationship with Bleu mostly consists of following him around, hurling gay slurs at him, and occasionally complimenting him under his breath... until he confesses that he thinks he's gay, and attracted to him.
While the trolls in Homestuck has a rather bizarre romantic system that makes both Type A and Type B a social norm, Vriska takes this Up to Elevenand beyond. Poor Tavros is so frightened of her tsuntsun side that the deredere side never even occurred to him.
Karkat is a slightly more typical example - he rants and yells at basically everyone he comes across, but every now and then he'll display how much he truly cares deep down. His relationships with John, Sollux, and Jade are probably the best examples of this. He and Terezi are probably mutually Type A, simply because of how much she likes to mess with his head.
Unfortunately there's evidence that Karkat's behavior is a result of being a people person, in a species where being psychologically healthy means being a Grade-A misanthrope, and aware of both his own damaged psychology, and the social stigma attached to it.
Natani, from Twokinds. She has a crush on Keith, but love isn't one of the defining qualities of a hit-and-run assassin. Having a supposedly male personality doesn't help.
Yuudai from Sakana is very tsun around his co-workers, and very derearound his cat. The moments where he actually shows his kind side to them are rare indeed. He is not a bad guy, though.
He is also notably flustered when Taisei is not put off by Yuudais Jerkass behaviour and instead immediately accepts Yuudai as his friend and pulls him into some sort of "bro hug", thus invading Yuudais normally well-protected comfort zone. He then begins to treat Taisei a bit better and even defends him when someone yells at him and treats him rudely, showing that he does care.
El Goonish Shive has Grace, sweet and naive most of the time but capable of near-psychotic fury against muggers and turtles who kidnap princesses. Tedd's a male example - threaten Grace and YOU WILL DIE HORRIBLY. Actually, most of the main cast is this (except for Susan, who's a Type A.)
Emily from Misfile is quite capable of turning into the Clingy Jealous Girl anytime someone else puts the moves on Ash, but fond of giving Ash the cold shoulder or verbal smackdown if Ash makes a move on her. This is because Ash is currently a girl and Emily is not gay at all.
Pee-Jee is a type B. She's a genuinely nice person, who happens to have a violent temper. And when she snaps, blood splatters.
Despite what she says in this strip, Eri-chan in Okashina Okashi is closer to Yandere than Tsundere.
Parodied somewhat with Chiaki in Sparkling Generation Valkyrie Yuuki where the character in question is left in utter bewilderment by her own jumps between happy and exceedingly depressed explaiming that she has "No idea how she should feel!" Truthfully, she's more of a genki girl, but...
Parley from Gunnerkrigg Court won't stop pestering her medium class colleague Smitty with arm locks and noogies and anything that requires her to put her arms around him. He puts up with her treatment because he thinks she's "hotter than hell". After she did finally admit the obvious, we find out that Smitty "don't mind too much" annoying things that happen because of her either... in part, because of her attitude.
Parodied in this strip of Tomoyo42's Room. (Comic NSFW.)
Monique from Sinfest pretty much gives equal time for her "tsun" and "dere" aspects, especially with Slick. Fuchsia, on the other hand, is either this or a Yandere.
In General Protection Fault, a grown up Sydney in the Bad Future acts like this toward Todd, expressing irritation at having to save him from police bots and his defeatist attitude regarding the rebellion, but sees him off on his time traveling mission with a kiss. According to an older Professor Wisebottom, she has loved him for years but has never told him.
Yuki from Ménage à 3 is an extreme type B towards Zii, and an extreme type A to Gary. In fact, she's leaning towards being a deconstruction, since her tsundere tendencies lean uncomfortably towards yandere, and she's starting to realize how destructive that behavior is.
Elf in Schlock Mercenary is somewhat emotionally unstable and prone to overreaction even after she kicked combat stimulants addiction and generally felt happy and appreciated. Before that, she oscillated between "nice" and "violent" much faster and easier.
