Dr. Wing Ding Gaster was the Royal Scientist before Dr. Alphys and the father of Sans and Papyrus.

Like most of his ancestors, Gaster is autistic. He knows how to manage his disorder fairly well and thus avoids scenarios that would make him uncomfortable. He has a fascination with things like scientific theory, souls, or magic, and can talk about them for hours. He can also get so focused on something he will forget to eat and sleep. On the other hand, he can also focus on a distraction to the point that he can't focus on anything else [40]. Gaster's stimming primarily takes the form of hand movements [39].

Gaster's hobbies include reading nonfiction with the occasional crime or romantic comedy novel, talking over tea with friends, and solving puzzles, though he isn't good at making them [47]. He is also Hermann's beta reader [52].

The experiments Gaster conducted on prisoners consisted of dipping individuals into Void Tears for some amount of time and then removing them and if they were still alive, documenting their experiences and injuries or if they died, analyzing their dust. Unbeknownst to him, the nature of the Void rendered these experiments pointless. Those that did survive were subjected to invasive procedures to figure out what made them so special, leading to his conclusion that Determination was essential to survival in the Void [55].

## Abilities

Gaster is lacking in physical power, but is particularly strong magic-wise. Prior to falling into The Void, his body was frail, but the struggle to survive in the Void raised his HP and MP drastically [14] along with giving him greater sensitivity to space-time disruptions and can instinctively sense whether a person or object is extradimensional [38].

He fights at range, keeping his distance and pelting his opponents with bones while countering their ranged attacks by intercepting them with more bones. He also immobilizes an enemy by surrounding them with bones and is particularly fond of blue attacks, as they make standing still or moving beneficial [21].

### Known Spells

Gravity Magic (telekinesis)

Magic Eye

Summoning magic (bones, gaster blasters)

Teleportation

### Physical Traits and Abilities

Genius-level intellect

PhD [46] Gaster exceeds Alphys at theoretical sciences, soul science, and knowledge of the Void [53].

Skeleton physiology

Void-touched enhancements [14]

### Skills

Cooking - When Gaster has to cook, he uses a special set lab equipment kept in a separate cabinet labeled "For Cooking Only" with the equipment itself having a label reading "Alphys if you use my cooking equipment for science again then I expect you to pay for replacements this time" [49].

Teaching - Gaster is inexperienced, but has secured the position of Magical Science Teacher permanently [56].

### Last Seen Stats

## History

### Pre-AFAC

Gaster didn't have many friends before meeting Hermann due to his arrogance [26]., though someone he knew kept telling him that he couldn't prove that teleportation didn't kill you and create a duplicate at the destination, which while he knew this to be untrue, still impacted his ability to teleport [31]. Despite how things turned out, Gaster and Hermann didn't like each other but kept running into each other. She made it her personal mission to make him laugh, and while he tried his best not to, he eventually did and they became friends. It took Gaster roughly a year and a half to realize his feelings [41], but when he did, he knew he had to tell her and that led to him trying to tell her and Hermann roping him into ice staking before they kissed [35]. Over the course of their relationship, Hermann helped Gaster see that while his way of viewing the world was perfectly fine, other people's views were just as valid. However Gaster's father Semi didn't approve of her, believing her to be uncultured and stupid, and Gaster grew distant from him [32]. Sans was an accidental pregnancy that lead to Gaster and Hermann getting married [22].

When Papyrus was only a baby, Blake accidentally shot and killed Hermann and Gaster nearly succeeded in killing them. Following that, he began experimenting on convicted criminals and Hanah, extracting the latter's Determination, other souls traits, and blood and tissue samples [61] over the course of a few weeks [18]. Hanah later escaped by making the holes in Gaster's hands with a laser cutter. After passing out from the pain [60], he was later found by Alphonse and taken to the hospital, calling the holes in his hands a "lab accident" [15]. To this day, he has told no one what actually happened [27].

Gaster had plans to experiment on Undyne when she was a child. Because of her Determination soul, he theorized that she would be able to survive longer in The Void and was planning to send her there, but before he could get very far, Sans and Alphys figured out what he was planning and confronted him about it [16].

After completing his work on The Core, he attempted to commit suicide, but had second thoughts as he was falling and tried teleporting. However, he got the coordinates wrong and wound up shattering his soul [23] and was transported to The Void [12]. However, some of his pieces remained in the world and anchored him to reality [44]. Some of its inhabitants took an interest in him and became the Gaster Followers, taking on forms we can understand and interacting with the people Gaster was watching [7].

Because he was in The Void, functionally, he didn't exist, so everyone forgot about him. Sans was able to remember him via willpower and Hermann was able to remember because she had died [5]. Over the course of his time in The Void, he slowly managed to piece his soul back together [23]. while he observed the AUs surrounding him. The other versions of himself that were good to their world's Sans and Papyrus hurt him deeply because of what he could have been to his sons [33]. During the genocide run, Gaster spent the majority of Chara's fight with Sans distracting them and pleading with Frisk to cast them out [20].The characters reacted to his return in a manner similar to suddenly being able to hear the askers [6]. At one point during his time in the Void, he encountered another gaster abandoned by their creator floating by that was taken by the goddess Trashlandia, who told him that she was adopting the other gaster and never saw either of them again [45].

Gaster got Chara killed many times during their genocide run by distracting them at inopportune moments [54].

During Frisk's pacifist run, when they ran into him, he screamed at them because this was the first time in years someone had actually been able to see him [36].

### Red Echoes

Sans pulled Gaster out of The Void, ripping a hole in space-time behind the couch, but inadvertently allowed Chara to escape. When Frisk ran off to Mount Ebott to find Monster Kid, he came with the cast to rescue them. He teleported the cast into Waterfall just in time to prevent Chara from killing the Riverperson.

The askers reveal that the Riverperson is Hermann, and she chewed him out for his cruelty, causing him to break down crying. At the end of the arc, he tried stop Hermann from leaving by teleporting close to her and falling into the river. Unfortunately, he had consumed orange tea and Hermann had to fish him out. He revealed she has a soul again and Hermann agreed to come back to the surface with them.

### Sweet Dreams and Nice Creams

Gaster encountered MWSIH!Gaster and they debated whether the other was evil and they both wound up with an anxiety attack on the ground. They had breakfast and Gaster mentioned they are on the surface. MWSIH!Gaster immediately teleports outside the house. After MWSIH!Gaster melted from the embarrassment of nearly killing Toriel, he helped Hermann mop him up. MWSIH!Gaster later asked Gaster to help him revive Lucida and he reluctantly agreed.

When MWSIH!Sans tried to call MWSIH!Gaster, Gaster picked up the phone and had a conversation with him before passing it to MWSIH!Gaster. Finally, Gaster saw MWSIH!Gaster and Lucida off to their world.

### Extra Dark Chocolate

Gaster's first appearance is when Frisk came to him for help translating Maverick's message and got upset at how terrible his puzzle was. Later when the cast was watching Alphys's security tapes, he anticlimactically reveals what Undertale is and AFAC's relation to it.

### ¡Eclipse Total!

Gaster opened up the arc with his first class at School, giving a lecture about souls. He threatened to send Blue Cottoncandycuteness Pinkcloud jr. and Monster Kid to the principle's office for nearly setting fire to the classroom with their argument.

He is last seen playing the maracas during the musical exorcism before throwing ADC!Chara and ADC!Frisk through the portal and agreeing to help Alphys set up an alert for when someone comes through the portal.

### The Most Fabulous Place on Earth

Gaster only had a brief cameo in this arc in a flashback from Frisk's time in the Underground.

## The Gaster Family

The Gaster family is descended from Georgia Aster, the first person to make a contract with Gaster Blasters [24] and the family name was later changed from Aster to Gaster [25]. The Gasters keeps her name for the prestige of being descended from her, but they have largely abandoned the idea that this bloodline makes them special [19]. Even still, they are the only ones with the ability to summon Gaster Blasters, due to Georgia Aster's pact being passed down their family line [24].

Historically, many of the Gasters have been autistic and they wear it as a kind of badge of honor that has lead to arrogance and the Gasters believing it makes them better than most people. Should a human explain autism to them, the Gasters would be confused that they would consider being a genius to be a disorder [26].

## Trivia

* He prefers his coffee dark [1].
* He is afraid of teleporting [2], as a failed teleport of his caused him to scatter across space and time.
* Owns a pet lizard named Pasteur [4]

* During Red Echoes, the flashback involving the scene where Hermann and Gaster went ice skating, the important thing he wanted to talk about was confessing his feelings [13].
* Gaster had two reasons for not involving anyone else in his more unethical work. One was to prevent anyone from revealing what he had been doing and the other was to ensure that if he was discovered, no one else would go down with him. He spent the course of his experiments consciously trying not to see the test subjects as people [28].
