How would you write the book boys? As in Hadie, Jr(Lonnie's brother), Aziz and Herkie? Personality wise?
Aziz is a lot like his dad- on the surface, he's a mischievous, happy, fast-minded kid with a stubborn streak two miles wide. A bit below that, he wants to make sure that he does everything in his power to keep Agrabah from going back to the way it was before his maman ruled. He doesn't want kids to go hungry, not after seeing that his dad still sneaks and stores food decades later. He cares a lot for his friends, more than Auradon masculinity standards would like, and he's kind of the mom friend of the group while also being the one who suggests extremely stupid things like putting soap on a trampoline "just to see what would happen." TL;DR, he's a lot like his father, cares a lot, and is usually the Bad Idea person in his group.
Hadie is just a kid. He's very curious, always ready to learn more, but he's also very cautious. He has ADHD and is usually always stemming in some way, usually vocal stims like humming or repeating words. He's also sweet once you get to know him, a bit brash and hard-headed like his father, and he got a temper from both of his parents. His friends Celia and CJ make the most of this. They like to use his flaming hair to either cook stuff or set stuff on fire. Maleficent says he's no longer allowed within fifty meters of Judge Frollo.
Jr (Li Susu) is a lot like his mother. He struggled with the role he was supposed to have, being a warrior, and found himself more drawn to the arts. The only reason he took to swords was because they were a type of art, making them and using them in dances came naturally to him. He really likes music, especially writing music, and he's usually humming a new tune while practicing ROAR or making swords. He also loves dance and parkour. He's kind of awkward like his mother, but he's patient and quiet, very well-mannered and not quick to let his emotions show. He also messes up with English a bit, just because he was raised speaking and writing Mandarin, but most people like his so much that if you insult him for this, half of the school is after you.
Herkie (his full name is Hryhoriy, pronounced with the same feel as Gregory, but he's given up on trying to get people to call him by it) regularly rips the shit out of Zeus. He will readily call Zeus out on literally anything and he does not fear his grandfather because Hera supports him and if there's one thing Zeus fears, it's Hera's divine wrath. He was one of the biggest advocates for talismans for the Isle gods, and he was one of the biggest voices in trying to get the children off of the Isle (especially the godly children like Hadie and Justice.) He was the one who found loopholes to keep Auradon from annexing the Demigod Stronghold, adding sports teams and classes so that it would be counted as a school rather than as the mixture of camps and cultures that it actually is. He's got a lot on his plate because his parents have a lot on theirs, so he's very quiet. But he's very sympathetic to the (reasonable) plights of others. Even if your problem is as mediocre as "I hate this class," he will listen. He's one of the ones who's been quietly building a network for when Isle Kids eventually came to Auradon as the Fates said they would. He even got Tyche to bless them.
Artie (Arturius, why can't people pronounce that?) is very patient. He might be fifteen but he's wise beyond his years, he needs to be. His father was forced to send him to Auradon and he faces a world that's so backward compares to what he comes from. Ystin was supposed to watch out for him, but he's the one who watches out for Ystin because for the love of god, people, Ystin is a guy, Merlin did magic to make his body match, stop calling him a girl. Auradon is so queerphobic and so anti-magic, both of which his home isn't. If he wasn't so wise and calm, he would get expelled because of how backwards he would call Auradon. He lets out his anger in English class. He writes papers on why Ystin is a guy or why magic is not inherently evil. 44 injured 13 dead every time, that's the level of ass-whooping his English papers unleash. He makes a very good point.
Anthony drinks Respect Women juice. He's also very estranged from Drizella, because she's so racist and he's half Indian. He keeps up a facade on the Isle, pretending to be snooty and holier-than-thou, because if people found out he still cared he would probably get beat up, but he's very caring. He's the mom of Harriet's crew and usually the only one of the polycule with at least one braincell (they share two, he has permanent custody of one of them.) He really wants a better life for the children of the Isle. He also really wants to meet his father, introduce his father to his girls, his man, and his kids, because he knows his dad doesn't even know that he's a grandpa. He writes a lot of letters to his father and aunt and has them all locked in a box, along with pictures commissioned from Mal, to give to them once he has the chance. He also really wants his mother's freedom because she's so, so sad, and she doesn't deserve to be. She saw the light, she was good, and who the hell sentences a pregnant woman to the Isle? He hates Auradon.
Diego, as previously shown, was the only parent for three family members so he had to grow up fast. He also cares a lot, a lot a lot, but he doesn't hide that he does. Other than that, he's a usual punk nineteen-year-old boy.
Clay Clayton, Gaston II and III, and the Stabbington cousins are all sexist and bigoted.
Rick Ratcliffe is working on unlearning a lot of bias from how he was raised. He tries so hard, he's very kind, and he might not realize some of the stuff he says is bad (he did accidentally call a few black people n*groes before Facilier corrected him) but he will always stop the second someone says "hey, that's actually bad." He really wants to learn and improve and he'll give Jay some stuff from his father's mansion because Jay was the one who finally knocked sense into him.
Reza, because I didn't realize she was actually written as a boy, is now a trans girl! Good for her!
LeFou Deux (Davin LeFou) has Down Syndrome, which is why Gaston abandoned him, but don't underestimate him because of it. Yes, he is naturally very sweet and friendly and he struggles a bit with learning, but he's still a person and he's not a baby, so don't treat him like he is. In fact he'll usually be meaner and more sharp-tongued than he is around friends, just to prove that he isn't an invalid.
Jace is estranged from his mother because he called her out on being racist. He and Harry are both a bit dim in terms of street smarts, but Harry has incredible emotional smarts and Jace is nearly as book-smart as Carlos. Both of them also struggle with social cues because the only friend they had for most of their lives, apart from each other, is Carlos, and he's autistic.
If you want I can make another post on the dwarf kids, this one is long enough.
