I have a HiJack Punk/Nerd AU concept
Its like a mix of both pnau and r!pnau
so jack frost is your typical trouble maker punk with studs in his ears and undercuts and what not -hes also one of the most infampus students at Dreamworks high. he gets detention nearly every day, flippantly disrespects authority and gets away with it, and is generally considered an untouchable high school god.
hiccup, on the other hand, is considered a societal outcast because 1) hes a nerd, especially about engineering and dragons 2) he doesnt talk to others all that much, very quiet 3) he wears SUPER BAGGY CLOTHES so he must be skinny
no one would think that these two were dating
jack frost in reality is very much a geek, loving folklore and childhood related mythology and actually styled himself as a winter spirit. his punk style is really because he has no impulse control and half of these fashion choices were dares from his friends (damn it aster)
HICCUP, on the other hand, is super, super sarcastic and very deadpan. the only ones who have made him laugh successfully are his best friends astrid and toothless, and, of course, his boyfriend jack. he's also very toned because he helps out his uncle gobber in his workshop, aptly named "the blacksmiths" and has had to carry stuff ever since. and despite popular belief, hiccup's more of a badass than he lets on because he already has his own bike, took on martial arts classes with astrid as a joke, AND has a tattoo he hides with his baggy sweaters.
jack LOVES hiccups tattoos. loves them. he's also adopted astrid's habit of braiding hiccups hair, which hiccup then undoes when they get to school.
bth of them arent really asahmed of their relationship, but theyre such little shits that they make a game out of hiding their relationship, going so far as to convince their friend groups to not associate with them as often
this doesnt really crop up to drama, bc like the smart teens they are they have group chats in which they constantly pester their real friend groups about how fucking bored they are
jacks super happy in comparison to hiccups surliness
jack pretends to push fishlegs around but actually shoves him to hiccup
fishlegs actually figures it out and realizes that hiccups actually more of a punk than jack is but also not?
i mean, theyre normal people.
no one knows jack helps out at the kiddie community center and is super popular with the kids there. its how he met hiccup, actually.
toothless attends the community center and has hiccup pick him up with his bike which he shouldnt even be driving
hiccup does not have his license yet, but hes working on it
jack's impulse control is basically hiccup saying "i dont think this is a good idea, babe" "NONSENSE WHERES YOUR SENSE OF ADVENTURE HICS"
jack is most definitely a cryptid hunter with his cyptid parter jamie benett
jamies in his last year of middle school when hiccup and jack are sophomores
stoick and jack's parents know the two are dating and are pretty accepting
stoick's fight with hiccup was actually about toothless prior to adoption. kiddie hiccup was adamant they help his mute friends but stoick, already worked to death, refuses. but then morals come and stoick realizes having a brother would be good for them both, and welcomes toothless.
hes fucking mad about that name though. eventually, he and hiccup agree that toothless is a nickname and taanlaus (from hitchups) is his real name...which toothless finds hilarious.
anyway jack is super precious and hiccup would throw hands in a heartbeat
if any of you have more to add feel free to!
