FBACC Headcanons because i can >:3
(and also because there’s not enough of them on here-)
[also for some reason almost every character here has at least one family-related hc,,, they’re fun facts i guess lol]
Fanboy / Tobias Cranapple III
12 year old bisexual boi.
Is autistic and has ADHD.
He is an only child. His mom is a news reporter (this hc was inspired by this fanart btw) and his dad was a superhero.
His dad is dead 😀
Has daddy issues (Robert Robertson style, aka his father was distant/always busy with his job and Fanboy feels the need to continue his heroic legacy after his death.)
Is very close with his grandpa, he’s the one who taught him how to be a hero when he was younger. He also taught him kung-fu.
Has only one cousin who is from his mother’s side. She’s like an older sister to him and they love to gossip about their classmates together.
Chum Chum / Edmund Chummery
10 year old pansexual boi.
Has ADHD.
Both of his parents work as secret agents, but he likes to think that they’re government spies. Agent Johnson is their co-worker and friend who often hangs out with them outside of work. Because of this, Chum Chum sometimes calls him his uncle.
He’s the youngest out of his siblings, and second youngest out of his cousins (Muk Muk is younger than him by a few days). His family is pretty big, and probably has more than just superheroic and chulkistani ancestry.
He ‘skipped’ a grade or two because Fanboy sneaked him into his fifth grade class so they could hang out more.
Additionally, he failed all his tests on purpose so he could be held back in class with Fanboy.
May or may not have had a short-lived tiny crush on Yo before finding out how crazy and obsessive she is.
Kyle Bloodworth-Thomason
i know that the majority of you hc Kyle as a gay trans boy, but I personally see him as an omnisexual transfeminine boy who goes by he/she pronouns. And she likes to be called Kaylee sometimes.
Is also 12 years old (slightly younger than Fanboy)
Is autistic.
Also an only child. His mom is a witch while his stepdad is a ‘muggle’.
His bio dad was a necromancer, and he gave Kyle his Necronomicon so he’d have something to remember him by before he left his life due to the divorce (Kyle’s father was similar to Fanboy’s dad, but he actually cared about his son).
Scrivener Elf was given to him by his mom as a birthday present. Take that as you will.
Used to be best friends with Sigmund back at Milkweed until Sigmund became popular and egotistical.
Has had his teddy bear Admiral Fluffington since he was a toddler.
Sigmund Z. Sorcerer
His full name is Sigmundius Ziegler Klein
Bisexual Transfem Bigender, would go by she/he pronouns and the name Sigrid if she wasn’t so deep in the closet.
13 years old
Albino.
He’s the eldest son, but still a middle child. Comes from a rich family, fancy mansion and all. Motherless, was mostly taken care of by maids when he was younger, still somehow ended up as a papa’s boy.
Is actually adopted but has no idea.
His dad was always single but always wanted to have kids.
Has a baby pet dragon. And probably a collection of other reptilians such as newts, geckos, skinks, bearded dragons and snakes. And he has a name for each one.
He’s a sucker for romantasy books.
Ozwald “Oz” Harmounian
Bisexual transguy in his early 20s.
Look me dead in the eyes and tell me he isn’t autistic.
Has a twin sister who lives out of town.
His dad died before he was born.
Probably watches anime and has a secret stash of anime figurines.
Is an aspiring cosplayer.
Has read the entirety of Warrior Cats.
Can’t cook for the life of him (is banned from the kitchen)
Has a degree in engineering, hence he knows how to build robots.
In the future, he was the one to teach Fanboy/Fanman how to make robots.
Taught Fanboy snack-calls.
Is a cat person.
Secretly loves puns.
His ponytail is always greasy.
Lenny Flynn-Boyle
GAY. Demiboy. he/they. Mid-20s.
Has paranoia and social anxiety.
Has two sisters.
Used to be ‘the talented child’ and now he’s the ‘family disappointment’.
Lives very far away from his family because of this and never visits.
His parents wanted him to become a doctor or a lawyer and that shit.
Boog Shlizetti
Pansexual guy. Mid-20s.
THAT MAN HAS AUTISM. CHIMP CHOMP IS HIS SPECIAL INTEREST. HE STIMS BY BOPPING PEOPLE. (the last part is a joke but he’s definitely neurodivergent)
Has a bunch of brothers.
Allergies to everything run in the family.
Is a pro gamer at Chimp Chomp, but is an absolute loser at every other game.
The only people he doesn’t bop are his nephews and nieces because he has a soft spot for them.
Hank Mufflin
