MINI-HEADCANONS: ONE.
↳ my old post is pretty outdated now, and i've expanded the majority of the things on it into full posts of their own, so here's an updated one of headcanons where a full post would be unnecessary.
¹ˑ karl speaks three languages: german, romanian and english. german is his native tongue, and the language a majority of his notes and recordings are in ( as no one else in the village spoke german - an incorrect assumption on his part ) but for everything else, he defaults to romanian as it is the only shared language spoken in the village. he was taught it from birth, given his heritage from the village and his mother coming from a romanian family, but spoke it very little until forced to default to it by miranda. he will rarely speak his native tongue around other people, and though he rarely uses pet names as anything other than derogatory sarcasm, he will usually opt for romanian out of habit - similarly, the use of phrases / idioms will be in romanian or if speaking to an outsider who speaks english, attempt to translate them, resulting in odd phrases ( an example of this is the idiom "oil from a rock" rather than the more common "blood from a stone" ). karl learned english through watching old hollywood movies which resulted in his transatlantic accent and his distinct speech pattern - as well as his penchant for dramatic monologues.
due to only ever hearing english words, his spelling whilst atrocious in general due to how painful writing can be at times due to the overuse of his hands / the constant electric stress on his nerves, is far poorer in english as he spells words how he says them. he finds it difficult to write straight, and rarely do his letters align together, making it difficult to read - he also writes his r's indistinguishable from v's and writes s's with a sharp angular stroke. karl prefers to record audio logs than write notes, so he writes very little in general ( his writing is far better when using a tool he can control, which is why the signs are more legible, and when he does write with a pen or pencil, he holds it with a closed fist as opposed to between his fingers ).
using the in-game textures from the writing karl's board, i created a font for his writing. an example of what hiss notes would look like and how difficult it is to read can be seen here.
²ˑ karl is somewhat ambidextrous, but is left-handed. he carries the hammer with his right, however his cigars are often held in the left, and the cigar case and flashlight are on his left hip. he will default to using his left hand in most situations, and when it comes to using tools where he cannot use them comfortably with his left hand, will usually opt to use his powers instead.
³ˑ unfortunately ( for anyone who has to suffer his company ) karl suffers from a severe case of hoarding behaviours as a result of losing anything of substantial value ( taken by miranda ) and having little claim to anything but the factory and the mines. worktops, desks, chairs, shelves, whole rooms of the factory all suffer from his hoarding habits. most of the items he hoards are valuable only to him: tools, components, materials, boxes, scrap amongst things he has no use for but keeps ( such as fabrics, books, vehicles, food ) on the off-chance that he might need them one day.
⁴ˑ despite his laziness, karl enjoys having projects to keep him occupied, though the aforementioned laziness alongside manic episodes and his undiagnosed / untreated adhd often result in him never actually finishing any of them - he will move on to the next one and abandon the former without any attempt to finish or deconstruct it. should he escape the village, he would prefer to choose a bare-bones home that he can build upon or a home in dire need of renovation, both as a personal project and for the sake of it being built for him by him.
⁵ˑ prior to his powers, he had little interest in being an engineer, and was not expected to take over the family factories in his adulthood - that responsibility would have gone to his older brother, as the firstborn son ( and partly due to karl's undiagnosed medical conditions ). he had tried his hand at blacksmithing, and enjoyed it, but his mother thought it too dangerous for karl to do ( particularly given how easily distracted he is ) and wanted to wait until he was a little older to learn properly.
though incredibly intelligent, he suffered in academics, but where karl really excelled was with the older family tradition - that of rearing, caring for and breeding horses ( which is why his father wished to teach him blacksmithing, so he could assist in casting shoes ) which he found a far more enjoyable and active way to spend his time. seeing this, his parents were debating sending him to live with his uncle in the village so he could take over that side of the family business.
on occasion, whenever the duke stops by, karl will still shoe the horses as part of a transactional service between the two.
⁶ˑ as a result of the electrical current in his body / his internal machinery / the various waves ( micro, infrared, radio ) his body puts out his temperature runs exceedingly warm at all times. combined with a habit of wearing several layers and living in a place with little ventilation, alongside a general poor hygiene, karl is more often than not very sweaty. it does provide a benefit throughout the harsh winters ( though he rarely leaves the factory ) but results in a very grouchy and uncomfortable lord when the summer heat rolls in, as shedding his layers does little to combat the heat.
⁷ˑ due to exacerbated paranoia, karl refuses to sleep around other people - though he sleeps very little at all ( and when he does, it is in his quarters where all doors are triple-locked and barred from the inside ). he has never slept beside or with someone, in a bed or otherwise, nor cuddled / lain with someone - in general, people would find it difficult to sleep even just sharing a room with him, as he is inconsiderate and naturally loud. when he does sleep, it is usually fully-clothed and wherever he was sat.
⁸ˑ nowadays he rarely eats, but he prefers traditional hearty and fatty foods, generally those consisting of meat ( preference for pork or beef ), and heavy drinks with strong tastes ( preference for liquor over beer, and beer over wine ). he has no appreciation for ‘fancy’ food and lacks the palate to differentiate between delicate or unusual flavours, and his knowledge of herbs and spices is limited to those found in the village, but as he doesn't cook he wouldn't be able to identify them by taste. as it stands he eats very little that could be considered healthy and rarely eats any fruit. unlike the homes of the other lords, karl's is the only one where food cannot be found ( only portable gas stoves ) and the food he does eat, on the rare occasion he does, falls into two categories: over-cooked meat scavenged ( usually the carcass of the livestock in the village, so pig, chicken or goat ) or decades old war rations and worker meals that had been left behind in the factory. candy, chocolate and desserts are extremely rare and something he sees as a luxury, one he's rarely experienced.
⁹ˑ whilst karl would absolutely love rock / metal / noise music, he doesn’t have any real knowledge of it as a genre and really, the sound of it ( in terms of sound, similar to that of machinery, not the music ) is something he's intimately familiar with and hears on a daily basis. what he does listen to however is 40s-50s era jazz owing to his childhood, as jazz was extremely popular in the weimar republic, particularly american jazz ( prior to the war, of course, as even german jazz was labelled as "degenerate music" ). still, karl does have familiarity with the big names of american musicians at the time suc as billie holiday, glenn miller, nat king cole, duke ellington, john coltrane, etc etc.
and yes, he's very jealous of alcina's jazz career. not that he'll ever say that.
sidenote: whilst i generally don't take the voice actors opinions / statements as anything but opinions / their own headcanons, i have never stopped thinking about how neil said he had i can’t make you love me on the playlist he made for karl.
¹⁰ˑ following on from the above, whilst he loathes alcina for many reasons, one particular point of jealousy is precisely how worldly she is and how much knowledge she has about the outside world ( due to her living outside the village prior to the cadou ) irregardless of the fact that alcina's knowledge of the "modern day" is even older than his due to when she was brought into the village and severed from the outside.
¹¹ˑ karl favours neutral, earthy colours: gunmetal ( ██ ), navy blues ( ██ ), sandy tans ( ██ ) and pale khakis ( ██ ), olive ( ██ ) and army greens ( ██ ), dull golds ( ██ ) and deep browns ( ██ ). due to his protanomaly vision ( mentioned here in detail - his ability to differentiate red / yellow / orange / pink is severely diminished and he will see it as more yellow in hue ) he cannot see a full range of colours ( example of how karl sees most locations ). he doesn't like overly saturated colours ( though again, these are most often saturated greens or yellows, as other colours will be seen differently by him ).
¹²ˑ he can’t tie his shoeslaces very well because he's spent seventy-odd years wearing a certain type of boot ( tankers boots, which use buckles instead of laces ) and anything else he ties such as rope, wire, string, never require the use of a bow - it’s one of those ‘forgetting how to write cursive because you use a keyboard constantly’ type of things. if he did wear boots with laces, he'd just tie a big knot and then slip them on / off instead of untying them.
¹³ˑ whilst still a lord ( though whether that title has any meaning given he's legally dead / the village is empty and in ruins / his family is dead ), karl's wealth is now more in land ownership and business ( or would be, if he sold the mine / factory ) than actual money. he does have money, and a lot of it, but what was wealthy in the early 40's and 50's is no longer wealthy in the modern day - particularly when conversion is factored in. this is completely unaware of this, and would be in for a very rough surprise once he gets out the village, especially given he can't haul bags of coins around and has no bank account / would be unable to get one ( again, he's legally dead ).
¹⁴ˑ given that he has spent decades in the factory, night and day have little meaning to him anymore as does time itself ( he stopped keeping track of the months or years long ago, only ever keeping track during the time he was actively graverobbing to provide materials for the soldat ) and so, he doesn't really fit into the category of morning, day or night person. were he to leave the factory and keep a somewhat "normal" schedule, he would eventually be regarded as a night person / nocturnal, as the dark is far more familiar to him, as would be the lack of people around at night.
¹⁵ˑ to say karl lacks any skills outside of his macabre engineering would be incorrect - he's a machinist and mechanic first and foremost. he's very good with manual labour when his laziness can be overcome, and he's a handyman by nature. he excels at building, repairing, deconstructing and has skills ( though haphazard, he produces unconventional and functional results ) with things like plumbing, woodwork, blacksmithing, bricklaying, mechanics. he is also well-acquainted with farming and raising / slaughtering livestock. what he lacks however are any functional domestic skills or those that would be considered trivial: he does not know how to make a bed, he doesn't know how to use a computer or modern phone, he doesn't know how to cook or how to clean, pay taxes, drive a car, etc etc.
