HOLY COW I'M SORRY ANON, I DIDN'T KNOW I HAD THIS IN MY INBOX??? happens when you get nothing at all My first question! Thank you for sending in one \ o /

Uhhhhhhrrrrmmmmmm, my favorite ships/fictional dynamics...?

I'll go ahead and mention Alice and Randel from Pumpkin Scissors since for about a year or two, I made stuff for them (and a comic that's woefully on permanent hiatus: https://vsitante.neocities.org/midnightglow/ :( ) (I really have to put up a notice, ugh). I really love them, and I think I will fail in explaining why because--it's not necessarily an unique ship on the surface (big gentle giant/tiny strong of will wearer of pants in the ship), but everything around, for, and about them makes them exceptionally compelling.

Randel is a man traumatized by war, forced into it via financial slavery, even experimented on for the sake of an army unit. All he wants to do is make up for it, and actually help people, which is why he believes in Section III a lot. There's a very heavy insinuation that many of his actions may or may not be of his volition, and he's trying to deflect from them. (Read the manga) His entire current body is a result of experimentation and fights, with heavy scarring and Frankenstein-esque fixes present. (This is also why the Frankenstein monster is often used as an analogy for him in fandom, come Halloween.)

Alice, meanwhile, while a noble who grew up with all the needs in the world, has a moral and belief system that goes beyond typical "noblesse oblige." Even at risk of her reputation or even health, she will strive to do the right thing so long as it is just. This gets very blurry, as you might imagine. She also often finds herself against expectations of her gender, as she's much more comfortable being a soldier than a noble, and she doesn't think her gender should affect either one. To paraphrase a critique towards her from one of her sisters, why does she insist on wearing a military uniform to a ballroom gala when she has to be trying to get a husband in the first place? (Read the manga) In fact, her sisters had to acquiesce to Alice having an extra weapon under her dress, because she insisted!

These two end up meeting each and changing each other, due to their experiences and outlooks. Randel, for example, influences Alice to perhaps take other factors in mind and to not necessarily go all-hog, if it means it brings about unseen side effects. Alice, on the other hand for example, literally just treats Randel like a fellow human being, almost humanizing him in a world that constantly does the opposite. This is part of why Randel falls in love with her, while Alice in part falls in love with Randel because he's always there for her to be her shoulder--and the times he's not there, she actively tries to hide her panic and depression lmao. She doesn't understand romance, and in fact, if we're using tropes, she's the person who can't handle romantic things the way a man would, while Randel has no issue being as open the way a woman would.

I phrase it that way, because in the JP fandom, they're at times talked about as Alice the hero and Randel the heroine. Take that as you will.

If you squint at everything else though, you can absolutely argue there's a growing co-dependency that can become unhealthy (and has been unhealthy at times in the manga), and the kicker is that their relationship also becomes...not, "based on" this, but certainly is a basis: Alice is of higher rank than Randel, Alice being a Lieutenant and Randel being a Corporal. There's a "previous" couple before Alice and Randel, that tried to basically be romantic through military lines/ignoring power balance, and while it (spoilers) and (spoilers), it's insinuated that both Alice and Randel are so twisted in their own way, that their ranks (and in turn, their actions for each other) almost become a kind of..."engagement rings" is not the phrasing I want to use, but it's very much seen as evidence of their love for each other. Randel only wants to be Alice's Corporal. Alice only wants to be Randel's lieutenant, and when she tells him if he's willing to do dirty work for and alongside her like around vol. 23 or 24, he basically says "yeah, no stuttering, I will."

Again, you can squint and probably see an argument for a kind of unhealthy co-dependence. But it's the kind that I think a lot of people would understand, and one that doesn't necessarily harm others? Because both HAVE been good for each other and that's the killer.

This quote I DID look for, because I'm that true-pilled:

"A tool for killing...and a tool for justice...This is probably just the story...of two tools coming together..."

daps a napkin to the eyes

Anyway, UHHHHH. I only took the first half of your question to answer lol, but maybe you can see what dynamics I like in my very long-winded explanation. I do have some other favorite ships but they're very minimal with regards to fandom. I also am afflicted with the disease known as crossover shipping...But I have a lot more OC ships in total in comparison lol. I love my OCs...
