Wukong and Xiaotian have a slightly different dynamic for me: Sun Wukong is a lot more relaxed around Xiaotian than others realize, he lets some masks slip off when the human's around him since he sees himself in the boy, so naturally he feels a bit at ease while also trying to guide him in a right direction (history repeating itself? not in his watch). When Xiaotian starts developing more of Wukong's powers, he decides to teach Xiaotian to embrace the demon half of himself that's starting to grow within him. Tell me Qi Xiaotian is fully human after his body gets used to absorbing Wukong's powers—trick question, you can't because we've seen him endure incredible hits and although Wukong knows how hard to hit so Xiaotian doesn't get hurt, it's pretty impressive that he can get out of a rockslide unbruised.

It's implied in the show that they hang out enough for Wukong and Xiaotian to know where they're going and the whole "we don't keep any secrets from each other" from Xiaotian in S3 was very sweet so I like to show them off hanging around each other just casually, not even for training sometimes, just having fun and Wukong takes Xiaotian to other places in the city that Xiaotian didn't even know were owned by demons or spirits. It's fun!

WUKONG AND XIAOJIAO!! MY FAVORITE FATHER-DAUGHTER DUO!

I started an AU with them called Mamma Mia AU where Wukong adopts Xiaojiao and yada yada but then tumblr nuked it so I restarted with Revived AU — these two are my favorite for so many reasons.

Wukong has a habit of not wanting to accept help from others and Xiaojiao is there to ground him a bit; She's able to see through him sometimes and manages to summarize his thoughts easier than most others. Wukong says "no" and Xiaojiao tells him all the reasons why he should say "yes" instead and he buckles down not because he's annoyed at the fact she's right but because she's this sort of comfort for him. There's guilt in the fact he was the cause for the ring being stored inside her but the two help each other out with that aspect of their lives, Wukong addresses his mistakes and Xiaojiao shakes his hand before dragging him to a video game contest between the two of them. I also imagine they play pranks a lot on most people, just silly bonding.

Not to mention Wukong can use a little more of his strength against her and Xiaojiao can equally throw a rocket at him and he'll just cough.

MY FUCKING FAVORITE FATHER-SON DYNAMIC!!! YEAH!!! THIS!! THEM!! THE DUO!! THE OG!!

Nezha and Wukong have a closer relationship than most people realize from how much they seem to argue or disagree with things but in reality Nezha's just stubborn and doesn't want to admit he admires Wukong and missed him when he had to stay and guard the map for so long. Tying it to Journey to the West, Wukong and Nezha had the closest relationship with each other than they did with other gods, the youth immortal eager to help Wukong with tasks and even laughing alongside him when he joked.

Nezha doesn't have a good relationship with his father or his brothers (killed them and nearly killed his dad while his father drove him to die before getting revived again) so he was hesitant to accept Wukong as a father figure but definitely grew closer to him overtime. He's not very vocal like Wukong but he can get his message across in one or two words much to everyone's amazement.

They have a close bond and Nezha makes a face when people try to make fun of Wukong and then glares at Wukong for allowing it. They're fun! Very protective of each other.

Wukong: what's better than one demon?
Wukong: [holds up Yin and Jin] TWO DEMONS!!

I don't have MUCH on them yet but I do adore the idea of Yin and Jin trying to con Wukong and instead getting conned themselves, they try very hard to trick Wukong and almost get away with it but the Sage manages to see through it easily. He basically teaches them how to survive and the further how to fight since thye don't seem to be able to throw a good punch for the life of them — he invites them to dinner sometimes and it's an Uncle and Nephew dynamic for them :D
