A year or two ago there was a post asking for Sokkla headcanons going around, and so I'm finally making a master post of my own Sokkla Headcanons, divorced from the older post.
Azula pretends to hate the cold but being a prodigious Firebender she can lower and raise her body temperature to compensate. Sokka discovers this their first night in the South Pole as she becomes his personal space heater by accident and she strangely doesn’t mind as it means more cuddles.
This also works with keeping bathwater warm longer. Sokka frequently loses track of time when they bathe together as she keeps the water just as warm as it was in the beginning.
Sokka and Azula both being strategic and tactical geniuses, frequently play Pai Sho together. And are at such a level that Uncle Iroh is often left in awe when he watches them play. Anytime he’s challenged one of them he’s swiftly defeated and despite the loss, he’s ecstatic. Most Pai Sho players utilize a basic strategy(such as The White Lotus Gambit for the OWL members) but Sokka and Azula realize the weakness in that and rarely use the same strategy twice.
After the war, Sokka went back to Piandao and trained for several more months, and then trained with Mai to get better with throwing weapons, and then Ty Lee on how to Chi Block and to become more agile. This leaves him a very dangerous and skilled nonbender and he and Azula spar together several times a week. The Royal Guard and even Zuko watch on in awe.
Azula had never had a reason to use weapons as she was always strong with her bending unlike Zuzu, but since dating Sokka she took an interest in it, and she’s a warrior through and through. Sokka is amazed at how quickly she picks it up.
Azula is incredibly proud of Sokka’s creativity and inventions and often helps give him ideas, oftentimes not even meaning too. She also helps him name his inventions as she finds his naming scheme awful.
This one can be a before they started dating/helped them grow closer, but as they both serve as Zuko’s Chief Advisors, they come up with groundbreaking ideas together and often improve the other's ideas with something the other hadn’t even thought of. This has led to some amazing policy and change in the Fire Nation and has helped immensely with their Foreign relations.
Azula will never openly admit it but she loves food almost as much as Sokka and has introduced him to some of the Fire Nations' most delicious dishes that he hadn’t tried.
Azula is awful at doing her hair herself, so Sokka does it for her and gets her to experiment with other styles(keeping her trademark bangs ofc) and she is surprised about it. When she asks him why he's so good at it he tells her about how after their mother was killed someone had to help Katara with her hair.
This one is more Canon than HC, but I largely disregard the comics. But Azula loves her Mochi. Anytime she's feeling down Sokka gets the Palace kitchen to make her some and he gets her an assortment of Mochi for her birthdays.
One of the things Azula started doing after being released from the Mental Institute is painting. It's a form of therapy and helps her a lot. She was never allowed to have hobbies under Ozai and is finally free to explore herself. When she learns that Sokka also paints she's surprised. When she sees some of his works, including a giant painting that takes up almost a whole wall, of the Moon reflecting off a body of water(the giant wall painting is from @madamezuki Blood & Fire but it's so good I like it as well and just integrated it into my HC's and scenarios). His work leaves her speechless and she's surprised he's so skilled. They spend time in the palace gardens painting together.
Azula and Sokka being the extremely intelligent individuals they both are, love reading. History, arts, sciences. It doesn't matter. They spend a ton of time together in the libraries in either palace or his loft library in his penthouse reading together.
