#undertale headcanons

Anyways i'm painting the clothes right now, and i'm not liking how Night's is looking like, so i'll change it later, but before i do i'd like to make a question to myself cuz...

WHERE THE FUCK ARE HIS PANTS?!

I do not know why i forgot to give him pants.

Nightmare have you no shame? Walking around pantless!/silly/j

humans were mislead too, now thinking that the only combat style accepted for them is physical combat, which reinforces the "monsters are weaker" thing. of course they're gonna be fucking weak against a stab in the eye who isn't??? but nooo it's different when it's between humans.

in this blog I plan to write headcanons for undertale characters and utmv sillies alike!

So Orion and atlas were born to their mother Pavo (gaster) and father Hydros (gorgon monster). Their parents are childhood sweethearts and very loyal to each other. The boys grew up in a loving family despite the violence raging in their au. There were some cracks under the surface though.

Pavo is a BRILLIANT skeleton and was renowned for her contributions to laser gun technology in outerfell. She retired briefly to raise orion then atlas when she and hydros decided to have children. Her leaving the royal guards research team put her under a lot of scrutiny. To challenge the gossips, she put a lot of pressure on her sons to be successful the same way she was. Orion and atlas were raised with love of course, but also with a very extreme schedule packed full of education and training in every field she could think of.

Thankfully both the boys inherited Pavos brains. Orion went into armor craftsmanship and was getting a lot of recognition for designing elaborate looking and practical guard armor. Atlas went the mathematics route and would help with the calculations the other scientists needed.

Sometime during Orions early adult years and atlas’ teens, the family reputation took a big hit after their father slipped up during a disciplinary meeting for some lower guards. After loosing his cool and dusting the three trouble makers, it came out that he was well into the early stages of LV sickness. The scandal forced hydros into a quiet retirement and Pavos back into the guard. To keep the attention off their father, orion was also brought into the guard. He remained in his position as a full time arms and armor craftsman until the crash while hydros took over the rest of atlas’ education.

After the crash, orion had a huge row with his mother about wanting to quit the royal guard. He actually cut his family off and didn’t speak to them for about five years. It was atlas who got orion and Pavo to speak again through some trickery (and hydros holding them hostage in a room for a few hours). Pavo and Orion have a tentative truce for now. She doesn’t mention him giving up his station to become a tattoo artist as long as he doesn’t get on her case for sticking to outerfells old ways.

So if a monsters LV experience gain for each kill made is multiplied by 1x, a half breed monsters is halved so multiplied by .5x each kill and a mages is much less, .1x for each kill. Half breed monsters and mages have to do a LOT of murder to gain LV vs normal monsters. They’re also more likely to be resistant to the mind altering symptoms of LV gain.

Almost never / Literally never:

Swears when shocked or surprised:

Swears when frustrated or PISSED:

Swears frequently / casually:

Swears when it's funniest:

Swears when you least expect it:

Swears like a fucking sailor. You never hear a sentence from them without at least a “dammit”: red edge mal noir butch boss bruiser snipe slim slugger orion pitch swine possum partner Seth Captain Hook cricket mango roost harpy pepper lush weasel sir Flambe shield whirl wind truffle G pilot zeppelin

Swears when irritated. Doesn’t give a shit about others language: coffee casket hostess gamble rancher yarrow skull fossil Nikolai sunny moony sugar butler pesto stitches ishtar

Swears only when angry or irritated. Will tell you to watch your fucking language unironically: honey Cambridge steel Jupiter cider rowdy leviathan Barin

Swears when excited. Becomes terrifyingly formal when pissed off: star lilac maple reaper tempo crow gold periwinkle

Swears in response to a big shock like seeing a tree fall on a parked car or something: sans oak lord peaches ram compass scout gem sails quill papaya Alden Ollivander Hilda sparks

Swears only when it’s funny. Or sometimes just to break an uncomfortable silence: papyrus cash willow wine dice atlas barley hex tegu Artemis fisher salt taffy pudding jester cane nitro

A social cusser. They will swear when around friends who swear but otherwise is pretty clean worded on their own. Rust mutt ace bouncer heist moose marrow basilisk mamba Jasper lens charm silex medici

Doesn’t swear because they are pure of heart: pop Pluto thistle magma tremor finn vibrato zen needle stein Solar

Hates swearing and will totally get on your case if you do it in front of them: basil Helios cigar dandy filly saga pearl isis Donatello green
