The good Doctor Gaster.

what-the-floofin: Learning ASL, and Gaster’s helping. He’s still a bit too fast and delicately signed for me to keep up though, hehe Signing a simple ‘Hello, my name is Gaster.’ Or at least I hope so ahahaha *WIP*

All the Gasters I made in the last 2-3 hours. Jfc it’s like my weak spot or smth wtf((also they are in the order of making))

Haha look at how crappy this bg is :”D plus Gaster has lil’ to none shading at all but shhhhhhhhhh, I have no more patience for this pic.So like, this is my design for him before the accident (I love those headcracks so they’re staying af)

As I said (and hey, it’s 9 AM now and I haven’t slept whole night…I rly need to fix my sleep schedule) I need to draw more Paps! So here is a bit more of him…and kinkshaming Gaster bc u kno…he’s everywhere…

Fusion or smth, prolly just possession tho of my version of Gaster with my ver of Papyrus.W.D. Papyrusa bow to @borurou for the inspiration :”D (also u’ll see those doodles in a full vent art post but I needed him to have a separate post)

A bunch of Gaster doodles, he’s so much fun to draw

thebigmonstersucc: I drew @ksuriuri body horror gaster in a drawpile session with them.That wandering body horror eye ;w; <3 ASDSFDDHHD u r srsly killing me with thoseeeeeee <333I love our drawpile sessions >3<

So yeah, this is my concept art for raging Gaster [upper pic, and yes, his proportions are like that on purpose, I actually screwed them up in the second pic lol]And my part of drawpile session with @thebigmonstersucc

Smol doodle of my WD Papyrus and @borurou‘s Gaster!Papyrus(where r they going? what r they talking about? no clue here)btw it is not a shippy pic

moofrog: nutastic: I thought it was about time I make a Gaster video. Technically my headcanon voice for him is Dr. Mobius from Fallout New Vegas, but I kind of love him as Professor Farnsworth too. This if fabulous!

zelka94: Gaster for my bby @ksuriuri. I uploaded this 2 days earlier than I intended, because I am a very impatient person and I like to ruin my own surprises ‘ID Space overload for this one~ Also my own take on Gaster’s Gaster Blasters because

Wrist hurts > decides not to draw today > has an idea > draws it….JFCSo, this is Gaster & Grillby fusion [he DOES wear clothes, this pic was made for the general idea of the look, I am sooo never going to draw him again lmao, unless

crowtez: show me ur versions of gaster

sniggysmut: gaster. at least the way i draw ‘im. goopy and tentacle-y.

even-the-dog-is-a-bomb: some pixel gasters p2 because i can never just draw one

Wanted to do some more Undertale fanart, so here’s Sans and Gaster. I love the lighting on the eye.

sugarkillsall: So sometimes when I’m typing Gaster, I’ll sometimes mistype it initially as “gatser” and my brain immediately thinks Wouldn’t he put the wineglass’ bottom through his hand like a cup-holder?

accelinx: (hi i just finished undertale) I feel like since Gaster really has no set height he’d just prefer to be taller than anyone he stands next to so I put him next to giant sexy robot (who’s probably like 7′0″ or smthn idk) Bonus: rofl

paychiri: thedrawingbirb: I’m just…going to keep drawing dadster…now with babybones!Sans. I keep making Gaster cute goshdangit Yes!!!! dawww~ <3

lets-play-a-game-tumut: AU where Gaster gets a phone and proceeds to meme everyone from across time and space

ssweetart: swag-bird: ssweetart: swag-bird: ssweetart: I would like to dedicate this fic to @nsfwbutts for having such a hot hot lovely bone daddy Gaster to use as inspiration Gaster/F!Reader ALSO ITS FLUFF?Yes…..yes for now….mph also shit

dustymaw: i got a headcannon that gaster can control those things effortlessly. just like “ yea w/e”

knocker12: GASTER! 난 뭔가 제자같은 포지션이 좋다. 그러고보면 영화나 만화를 보면 왜 항상 과학자들은 사건사고를 일으키는가:D

drcrygor: who the fuck is gaster lmao

ttoba: Two science nerds being total dorks as usual. Gaster would have to stoop all the way down while Sans has to tiptoe to reach the taller nerd. I- *coughs out blood*

redmiel: I gave Gaster really long, thin fingers, and Sans lil tiny chub handsSo I’ve been thinking about them playing with their hand-holesI’m in hell

stolashoots: A drabble (2) Rating: High T!! Pairing: Sans/Gaster (Sanster) Sans wakes to warm breath tickling the back of his neck and fingers delicately caressing his sternum. He shivers and peeks open an eye, checking the time on a nearby clock. 8

thatonegojimun: i just… have a lot of emotions abt gaster ok

tresym: YOOO, It’s done! I kinda procrastinated on it but here he is, Gaster, in all of his threatening, towering glory. I made two versions because I like how clean he looks in the first, but the bloody one, mmm…Based on @nsfwbutts Mafia AU for

whatifgirl: Different Gaster design cause I’ve seen so many different interpretations of him either being elongated or just a big fat blob. I’m stuck between making him either super formal or out right creepy. But yeah haha. I was gonna draw more

hoardoftrash: people like to draw Gaster in some kinda robe, and I like to imagine it acts like some kind of void. So it’s good to hide in when playing hide and seek.

jeneco: A smol Gaster.Pixeling is still a pretty new thing to me but gosh I’m having a blast, this makes a lot of fun!

borurou: gaster/sans thing?¿¿?? idk

what-the-floofin: Learning ASL, and Gaster’s helping. He’s still a bit too fast and delicately signed for me to keep up though, hehe Signing a simple ‘Hello, my name is Gaster.’ Or at least I hope so ahahaha *WIP*

ghostalebrije: I read people headcanon Sans being Gaster’s assistant back when he worked with the Core before the incident that led to him being erased, and then other people shipping them together because of that. and like I’m p much already in

crowtez:Gaster has really grown on me as a character even if he’s really only referenced vaguely in the game.

fluffymilktea: [1] [2] 3-5 Decided to update early. The forgotten ones. A per-undertale AU where Gaster is the one who give Sans his power. Gaster decided to test out San’s new installment, but will the smol skeleton cooperate? school is busy….but

reseting4sinning: thank gosh i’m not the only one who feels that way I couldn’t help but draw both of the Gaster!Brothers. I hope the fusion gave them the knowledge of Sign Language. ‘Beware the brothers that speak in hands’ [Full View] Gaster!Papyrus

chaotichero: * BROTHER! A… ARE YOU OKAY? WHY ARE YOU CRYING?* ….i don’t remember.Anon threw a prompt suggesting Sans and Gaster reuniting. I decided to make it into a comic of how it would go alongside my headcanon :DBasically, Gaster can’t be
