I haven't seen many mcog headcanons, so here are some of mine (just the 3 kids for now, I'll do the other characters later)
- never really got over his fear of heights, despite his friends trying to help him
- can't cook cause he can't follow instructions
- sleeps late, wakes up early, naps during the day
- loves fruit drinks, punch, etc. I think he'd like mango lassi
- pinky promises for everything
- learned to swim while on the Esperanza (Mendoza threw him off board to teach him, he never forgave him for that, despite Mendoza insisting it was pretty funny at the time)
- loves old timey video games
- loves trying new sports, despite being bad at them
- took his first steps aboard the Trinidad
- also said his first words on the Trinidad (it was "mama" cause that's what most babies say first. Unfortunately, his mother wasn't present, but Mendoza was. The other sailors on board thought it was funny to hear the baby call Mendoza “mama". Mendoza, on the other hand, did not find it funny)
- This is a headcanon l've seen before but I love it so: he was named by Mendoza
- loves pulling pranks on his friends
- can only sleep if it's dead silent
- when it's his turn to pick a movie for them to watch, he puts stuff like high school musical
- probably claustrophobic
- loves holding hands with like, everybody
- Esteban taught her to swim (during season 1)
- loves to go hiking with Tao (Esteban doesn't join, he's scared of heights)
- loves classic Disney movies
- learns to knit and makes everyone sweaters
- likes ice caps with whipped cream
- plays with her hair when nervous
- Great at lying but hates having to lie
- would be great at badminton
- probably takes care of a snake at some point
- likes to gossip with spiders
- gets really close with Isabella cause they're like, the only girls in the story 😭
- post season 4: she'll sometimes take the condor to visit maina and her other incan friends
- learns to play instruments really quickly
- prior to season 1, when she's working in the palace, she'd look out the window and see a young boy in blue robes running down the street. She wished she could be as free as him and wondered where he was rushing off to. To this day she still thinks about that kid and never found out that it was actually Esteban this whole time
- can do a backflip, which makes Esteban jealous. Can also do various gymnastic stunts
- made a super complicated secret handshake with Esteban (they forget it every so often, so they have to make a new one every time)
- teaches Zia everything about Muan history (they also create their own secret code to communicate with each other, for funsies)
- Is really good at chess
- builds random trinkets in his free time. Scribbles plans for inventions on any surface he can find
- can't sit still for long periods of time
- kinda wishes he had powers like his friends do, but then feels bad for feeling jealous
- if school was a thing, he'd be in a bunch of clubs and groups
- stays up really late, no one knows if he even goes to sleep at all
- drinks monster energy drinks to stay awake
- Esteban continuously teases him about the crushes he's had (Maïna, Zia and indali)
- since he was all alone on his island growing up, I'm assuming it must've been hard to get food, cause he's a kid, so he'd mostly have a vegetarian diet. I mean sure he'd eat meat every so often if he was able to catch it, but idk I don't think that's the primary source of his food. Makes sense cause he's small and skinny despite being the oldest kid
- likes making friends but has a lot of trouble with it
- loves Star Trek and Doctor who. It's his go to choice for movie night
