Gaster Blasters

"Gaster Blaster" is a name given by summoners since they have no name for themselves [24], and their summoning is the signature spell of the Gaster family. They take the form of animal skulls. They are one of a category of Void Denizens that are fascinated by emotions and can be reasoned with, but are more reliable than the rest [10]. Alternatively, the incantation can be put into runes\* (This ask conflicts with later asks clarifying that words are a purely mnemonic device to help the caster focus and do not otherwise affect the spell. A followup ask is needed) [5] . The incantation is likely in some dead monster dialect and translates to an offer of painful memories if the blasters attack a target [6]. They are unrelated to Memoryheads [26]. For information on how to summon them, see here.

## Biology

Gaster blasters are actually intelligent residents of the void and as a result, have always existed and yet never existed [9]. Blasters are fascinated by physical and psychological pain [24], since they can't feel it themselves [10], though they also feed on the sensation [4], and the summoner offers up painful memories in exchange for the blasters being summoned and shooting at what you want shot, appearing quickly when offered memories [10]. Interestingly, while they want to experience pain, they have no interest in experiencing it first hand, instead preferring to feel the emotion secondhand. Georgia Aster theorized that the blasters were trying to answer the question of why mortals clung to existence if it is so painful, reasoning that this can only be understood by experiencing their worst experiences [24].

Like most Void Denizens, gaster blasters don't actually like being in a universe long term for fear of becoming real [24] and leave shortly after firing at a target, though they will eagerly return if offered a new painful memory. If they realize a summoner will need a lot of firepower, they'll line up and you can share the same memory with each of them to have them fire one after the other in quick succession [15]. Gaster blasters are surprisingly honest, but mostly keep their deals because they will lose their supply of painful memories if they stopped [17]. They do not age or reproduce thus lacking the concept of children or family, treat the descendants of the original contractor as an extension of the original deal-maker [13].

They are currently believed to not have souls, and they have little care for who or what they attack, only wanting to receive painful memories. However some seem to have the belief that pain and suffering make you stronger, and by helping their summoners they are making them stronger people. They are also capable of speech, giving some summoners the advice "Remember your pain. Let it strengthen your resolve. Let your suffering become a battle cry." This lends some credence to a moral code they follow that mortals can't understand [8].

Chiller is an exception, due to being created in Man Who Speaks In Hands [9].

### Blasts

The more painful the memory, the more powerful the blast, which may result in repeated memories resulting in weaker attacks depending on the summoner [4], though shame can also be used as a fuel source [16]. When a Gaster Blaster receives a memory, it opens a connection between the summoner and the blaster , making it It possible for the summoner to infuse additional effects like Karmic Retribution [3], but infusing healing magic into the blast, will cause the target not to heal if the power put in does not outpace the blaster. What winds up happening is a beam that triggers a state of healing and damage only suitable for torture [21]. Due to their quasi-real state, a gaster blaster uses the intent of the caster rather than their own for determining the strength of an attack [25].

## Pacts

While anyone can form a pact with the Gaster Blastes, the only one known to exist is the one formed by Georgia Aster [22]. This pact has been passed down her bloodline to her descendants [1], though the contract also includes anyone adopted into the Gaster family or those who have married into the family [18] as well as anyone related to any of those people and so on, provided the person knows they are descended from her [23]. The blasters' interpretation of what constitutes these requirements are incredibly lax, resulting in a person being able to be adopted without a legal process or even verbal confirmation [19] and dating being interpreted as marriage [23]. However, it is possible to trick the blasters into being summoned by a non-contractor. This is accomplished by a poltergeist or ghost possessing a person who is a contractor and casting the summoning spell as Chara did in Red Echoes. However, the blaster will eventually catch on that the memories given are not from the contractor, leading to the blaster at best losing power [14].

Making a pact with Gaster Blasters is difficult, as it requires you to get them to trust you, and it is fully possible that you might try to capture and experiment on them and summoning them at all requires magic [12].

## Trivia

* Georgia Aster called them "phantom pain" [7], but later were called "G. Aster's Blasters". People have since shortened it to "Gaster Blasters".
* When Georgia Aster made a pact with them, it was seem by some as the equivalent of making a deal with a Lovecraftian elder god [11].
