Aang as Zuko’s “Found-Sibling”
so i kind of alluded to it on my previous post but if zuko sees his relationship with any of the gaang as a foil to his sibling relationship with azula, it’s aang.
in the season 1 finale, zuko compares the two directly:
zuko: I finally have you, but I can't get you home because of this blizzard. There's always something. Not that you would understand. You're like my sister. Everything always came easy to her. She's a Firebending prodigy, and everyone adores her. My father says she was born lucky. He says I was lucky to be born. I don't need luck, though. I don't want it. I've always had to struggle and fight and that's made me strong. It's made me who I am.
here zuko makes a lot of assumptions. he is implying that because aang is a prodigy like azula, everything must come easy for him. we as the audience know this isn’t true (he doesn’t know aang’s background at this point), but it does speak to his insecurities in terms of his sister (foreshadowing to his season 2 interactions with azula.)
contrast that quote with what zuko says to katara in the season 1 finale:
zuko: you rise with the moon, i rise with the sun.
he sees katara as evenly skilled as himself. a match, but with opposite bending elements. and that’s even reflected in the way that katara wins their match at night, but zuko wins their fight when it’s day time.
zuko (especially in season 1) sees azula as superior to him, someone who he’ll never catch up to in skill because she’s a prodigy. in contrast, he’s seen katara when she first started to bend and made mistakes (barely able to form a water whip, and the time she accidentally froze sokka). zuko has seen and acknowledged her growth throughout the show and he sees her as someone who has also had to struggle and work hard to get to her current bending capacity.
and like @sokkastyles already said:
Aang is the younger prodigy who he resents for being better than him in the beginning, the one who is imbued with power and authority by birth that he lacks, the “lucky” one.
continuing on, i wanna talk about crossroads of destiny. the zk scene again emphasizes how similar zuko sees katara to himself (not azula.)
he is calm, open, and vulnerable throughout these scene with katara. he almost allows himself to forget they’re on opposite sides because of how much they have in common. but once aang comes in:
there’s that same anger and resentment he has towards azula.
i’ve seen some people refer to the crossroads of destiny as zuko some hidden meaning of choosing between “sisters,” but i disagree. it’s framed as a decision between azula and aang, and for zuko, it’s supposed to be an impossible choice.
so we see him go after aang with an uncontrolled intensity that is so different from the brief peace he was able to achieve with iroh in ba sing se. and it’s easy to imagine that this is because he’s taking his frustration that he can’t express towards azula, out on aang, as a substitute.
we see lingering bits of zuko’s resentment towards aang, even after he joins the gaang. it’s unintentional, but from the firebending masters, we can see how he initially still holds onto that insecurity a bit.
when he initially realizes he lost his firebending he tries the forms over and over, while aang is just chilling:
aang: that one felt kinda hot
zuko: don’t patronize me!
zuko: and stop calling me that!
even though aang was being genuine, it’s easy to imagine that zuko is connecting this moment back to times with azula growing up. especially because we know how much his ability to fire bend is tied up into his self worth.
he’s given the chance to “prove” himself by teaching someone who he considers superior in skill to himself (aang, just off virtue of being the avatar), and when he fails, that rears up the resentment again.
but then, their dynamic shifts after zuko admits he doesn’t want to rely on hate and anger anymore. zuko has several moments where he encourages aang (who he was previously resentful towards) because he sees that aang needs it. he’s able to realize that aang isn’t a prodigy in the sense that he thinks he’s superior to anyone else. and he’s also able to see that aang has his own insecurities as well, as they get to know each other more on their trip. he has phrases like:
zuko: you can do it. i know you can. you’re a strong kid.
aang: [Turning to Zuko.] We could turn back now. We've already learned more about fire than we'd hoped. [Aang shows Zuko his flame and gives a weak smile.]
zuko: No, we're seeing this through to the end.
and aang’s face as a result:
so in a sense, zuko is able to be needed as a big brother. and to offer support because aang is unsure about himself.
also this scene reeks of sibling energy:
but anyways, i think aang/zuko’s found-sibling relationship foils azula/zuko’s sibling relationship because even though they start off with resentment for similar reasons, his dynamic with aang changes.
i see people say that the reason they think katara is zuko’s “surrogate sibling” is because she provides him with care and kindness, unlike azula. the same could be said about aang.
whereas azula has made it clear that she doesn’t respect zuko’s bending, aang values and respects zuko for his skills (even when he was struggling at the beginning of the firebending masters.) aang is able to reciprocally affirm zuko as well:
aang: i don’t care what everyone else says about you. you’re pretty smart!
i also find the last few lines after they meet with the dragons to be significant:
zuko: That's why my firebending was so weak before. Because for so many years, hunting you [Turns toward Aang as screen zooms out to show Aang.] was my drive ... it was my purpose. [Aang turns toward Zuko as well.] So when I joined you, I lost sight of my inner fire. But now, I have a new drive. [Cut to Zuko's face as screen zooms in.] I have to help you defeat my father and restore balance to the world.
i’d like to think that part of losing/letting go of his anger/resentment in part was because of the new relationship he was able to build with aang. in a sense, he’s able to repair a “pseudo-sibling” relationship with a found-sibling who willingly accepts him.
i love that they’re address their confidence issues regarding firebending together.
and how, when they rushed to show the rest of the gaang after they returned:
aang: [Cut to Aang and Zuko demonstrating the Dancing Dragon to the rest of Team Avatar and friends.] With this technique the dragons showed us, Zuko and I will be unstoppable.
zuko has gained a found-sibling relationship that isn’t about comparing their firebending to each other, but working as a team. it’s so so meaningful that aang says “zuko and i.” the idea of zuko having a sibling relationship where he’s able to share his love of firebending and not feel insecure about it ...🥺. him having a “sibling” who wants to hang out with him and do things together and gushes about it with the confidence that aang had when he said they would be unstoppable.
oh! not to mention that i’ve seen people say that zuko/katara have a sibling relationship because she teases him in EIP. but like .. that’s such flimsy logic. and also? aang and zuko have their mutual teasing moments especially in the firebending masters, and it’s just adorable.
anyways, my main point from all this is that ik people love to say zuko/katara fit surrogate siblings (which i hate btw), but it’s mostly said because of katara/azula’s similar age. it doesnt matter that aang is 12, though, because honestly, he fits the “found-sibling” dynamic a lot better because of how zuko used to see aang in relation to azula. it just works better thematically. especially, because like i’ve said, and as so many people in fandom point out: zuko and katara are similar (some people... antis.. would say “too” similar). and when has zuko ever seen azula as being similar to himself? exactly.
