Royal Scientist (Formerly)
Rogue Scientist (Currently)

W. D. Gaster was the royal scientist before Alphys, responsible for creating the CORE. Gaster's Followers relay various explanations as to what happened to Gaster. One iteration says that he "fell into his creation," another says that "his experiments went wrong," and the last says that he "shattered across space and time."

Gaster is a skeleton that looks a little bit like the puppet, but with 1 black tear coming down from his eye, and 1 coming to his forehead. He has a black lab coat with a grey sweater. He has holes in his hands, and sometimes it does not show his arms, and sometimes it does.he also has glasses

Sans is his oldest son and papyrus is the youngest son

Gaster Blaster: Gaster can summon a magic skull blaster that fires a magic laser.
Telekinesis: Gaster can manipulate the gravity of a person, soul, or object, and move it around at will.
Magic Absorption: Right when Gaster was about to brutally kill Bête, he started absorbing magic from Papyrus' soul and slowly killing him. Giving magic to himself to supply his weakened magic.
Healing Magic: Due to being a monster, Gaster has the ability to heal others. Such as Papyrus when Bête crushed him.
Chromas: Gaster has this special type of magic known to monsters as "Chromas": This type of magic allows the user to use a bit of magic with each trait known. He expresses this magic by summoning up to seven magic Hands with holes in them (corresponding to the holes in his hands). The hole fills with the color of the magic he wants to use, he can also use chroma magic directly from his normal hands. If one of Gaster's children is alive, he can only summon six hands.
Shown in Yet Darker, Gaster can make each hand have a different chroma and can make all the hands blast a rainbow beam together, this beam follows the opponent and can be split apart into projectiles.

Monotone: This is a special ability where he makes all his hands use one chroma, making it seven times more powerful. He uses it with Patience in Your Best Friend, and Determination in Game Over Part 2. If one of Gaster's children is alive, he can only summon six hands, multiplying the power by six; he is also limited to this as his most powerful attack if both children are alive.
DUALITY: Gaster summons two giant hands, and one Gaster Blaster. He is limited to this as his most powerful attack if only one of his children are alive.
Polychromatism: Gaster's most powerful attack. He summons two big hands, one giant Blaster, and seven smaller hands. His real limit is seven giant hands and one Blaster, but it is too taxing on him, so he uses this instead. This ability is only available if Gaster has all his power (aka if both his children are dead or if he forcefully takes his magic back from them).
Former Abilities
Teleportation: During the experiment that led to him falling into the Core, Gaster and his son Sans both gained the ability to teleport themselves and others. However, Gaster lost this ability after being defeated by Bête in Do or Die. He is unable to regain this ability.[4]

Tentacles: When Gaster was in the void, he could use black tentacles to stop Frisk from resetting, trap Frisk, impale Sans and take Frisk's soul. Though, when Gaster left his room, he could still use the black tentacles shown in Yet Darker, though he is shown to not use this anymore up to this episode.he can also make appear other hands to help him out to do other things while his two principals hands are already occupied
