~ Gaster to Betty in Do or Die.

Summary

W.D Gaster, also known as simply Gaster, is a fan character created by youtuber Camila Cuevas from Glitchtale, inspired by the original fan idea of Mystery Man in Undertale. He was originally a royal scientist, though when the DETERMINATION incident happened, he falled into the CORE and started being forgotten by everyone as the new timelines happened. As he appeared in the Yet Darker and Your Best Friend episodes #2 and #4 of Glitchtale, he was restored to his original state of an anomaly.

Appearance

Gaster, in his room, takes the appearance primarily from one of the sprites of Mystery Man in Undertale, having two cracks in his face, a white skin, and a black robe.

When he gets out of it, his cracks in his face get "healed", and he is now able to stand upright. Most of his appearance remains the same, with the only exception his eyes turn red and blue when using his abilities.

Personality

Gaster is an individual who initially starts as someone who has been waiting so long for someone to "remember" him, as he is apparently mad at Sans for doing so. He is plagued with frustation due to that, as he tried attacking and absorbing Frisk's soul to take over the timeline, and he told Sans that he doesn't know what is to be "forgotten". Later on when Sans manages to bring back Gaster, he becomes more comprehensive towards Frisk and Sans, to the point he took a hit and saved them from Chara twice. He is analytical and appears to find the most logical outcome of things when he cans, but still has an emotional side, as he cares about Frisk and tells them to "stay determined". He appears to be a bit overprotective and can have anger issues due to that, as when shown towards Papyrus, probably due to the trauma of seeing him die due to blaming himself for the death of Sans.

Weaknesses: Gaster shows that he is prone to anger issues and can act in a way he can even damage those affiliated with him. He also shows that he is overprotective to an extent.

Notable Attacks/Techniques:

7 Hands: Gaster wields 7 hands, which he uses for his main attacks. They take the color scheme from the seven human souls, and have the same themes ambiented for his attacks.

  • Red Hand: The red hand uses blasts of energy to attack in a similar way to gaster blasters. It also can take the form of one, being noticeably more powerful than his normal attacks. He can also empower his physical attacks with one of them, as shown he could punch Betty with an red-energy powered attack.
  • Purple Hand: The purple hand copies every attack that is at it's presence, as shown it could copy Sans bones
    • Gaster showcases all of his seven hands.
    • Gaster using and showcasing Monotone with the red hand.
    • Gaster can also use his red hand to create a giant, red gaster blaster.
    • Red hand physical variation attack.
    • Gaster can use the purple hand to copy attacks that are at it's presence.
    • Gaster showcasing and using both the light blue and blue hands, as a combination.
    • Gaster using the green hand to protect himself with Duality activated.
    • Green hand normal variation.
    • Gaster can use the yellow hand to fire various yellow, energy like bullets towards the target.
    • Gaster can use the orange hand to make spheres which explode at activation or contact.
    • Gaster using and showcasing Duality.
    • Gaster can use his black constructs to block things, as shown with Frisk's buttons...
    • ...and also using them for attack purposes.
    and gaster blaster attacks.
  • Blue Hand: The blue hand is able to throw various razor blades to attack. Gaster has shown he can combine this hand with the light blue hand, making the rope tied to the razor blade and have better control over it.
  • Green Hand: The green hand summons a green shield which can be either omnidirectional or just in one side. He uses it to protect himself, others, or even encase his enemies with it, containing them temporarily.
  • Light Blue Hand: The light blue hand casts various strings which he uses to tie his enemies to prevent them from attacking. Gaster has shown he can combine this hand with the blue hand, making the rope tied to the razor blade and have better control over it.
  • Orange Hand: The orange hand creates spheres around the enemy which explode at activation or contact.
  • Yellow Hand: The yellow hand shoots several energy projectiles towards the enemy at fast speeds.

Monotone: One of Gaster's signature attacks. Gaster has all of his 7 hands turn into a certain color, from which he can use it to amplify the power of his next attack by 7.

Duality: One of Gaster's signature attacks, after Sans died. Gaster creates two levitating giant hands that hover at the side of his body, which he uses to perform stronger attacks with his regular hands, or do combinations with them.

Black Constructs: Gaster has shown he was able to create some black constructs out of his body, or the environment. They have been used to attack, encompass objects within them, or even prevent Frisk from using his RESET and CONTINUE buttons.

Polychromatism: Gaster can summon two giant hands, and all of his hands at once, as well as one giant blaster. The prerequisite to this ability is either that both Sans and Papyrus are dead, or they were not born yet. Gaster may be able to go past this setup and summon more hands, but this setup is the best one to use for him. In Animosity, it was shown that he can still use this ability even with Papyrus, and presumably even Sans present, but using it in that scenario drains the magic of the souls of any of his son(s) that are alive.

Trivia

Gaster has been confirmed of having 666,666 HP in Glitchtale, dwarfing most of canon Undertale's cast HP when compared to it (23,000 for Undyne the Undying, 30,000 for Mettaton Neo)

Some of Gaster's powers return when one of his "childs" die. As shown when Sans died, his left light blue eye went off, though Camila confirmed he didn't lose power, rather it returned. The same would likely happen when Papyrus dies.

  • Since Sans death, Gaster gained a new signature attack, Duality, which creates two giant floating hands that can be used to perform stronger attacks compared to his regular attacks. It is likely due to the reasons mentioned above, as his power returned.
