Beast I

Beast I (ビーストⅠ) is a Beast-class Servant who appears in the Grand Orders of Fate/Grand Order.

Identity
Beast I's True Name is King of Demon Gods, the aggregate form of Solomon's seventy-two Demon Gods. It was originally created as a protocol to look after mankind after Solomon's death, the Human Order Correction Protocol Goetia (人理補正式ゲーティア), but eventually changed into the Human Order Incineration Protocol Goetia (人理焼却式ゲーティア).

In its original Greek, the term "" refers to the act of sorcery itself; and in the Final Singularity of Fate/Grand Order, it is revealed that Goetia was the original Thaumaturgical Foundation (魔術基盤) used in Modern Magecraft -- the genetic curse that he implanted in the seventy-two Thaumaturgical lineages that hosted his Demon Gods being the basis from which the first Thaumaturgical Circuits developed. Said Circuits were from the outset a means by which he connected his existence with that of his agents.

Personality
It is the compilation of the seventy two Demon Gods, and thus has no definitive personality. When interacting with others, the Demon God with closest mentality to the opposing speaker surfaces, acting like a mirror.

Despite sharing the same perspective as Solomon during his lifetime Beast I never understood why Solomon accepted humans despite their flaws, as he sees human lives to be only full of suffering and despair waiting for death. Because of that Beast I feels that humans have no value due to their limited flawed lives, as such he is very sympathetic towards Mashu and believes she, who was designed with a short life span only to serve others, can understand his views about the eradication of death.

He has a great deal of animosity towards Solomon, describing Solomon's personality with only negative adjectives. He further considers Solomon to be the greatest fool of mankind and an incompetent king. Much of Beast I's hatred for Solomon stems from both Solomon's supposed indifference to the suffering of mankind, and for creating him to watch over humanity, a function he considers pointless due to believing that humans can only suffer until their deaths.

Salomon: Grand Time Temple
After Grand Caster is once again defeated, he decides to remove his disguise and reveal his true identity as Beast I, Goetia. He then attempts to convince Shielder to join him in creating a world where death does not exist, but she firmly rejects his offer and views on life. Disappointed Goetia launches Ars Almadel Salomonis at her, but she uses Lord Camelot to protect the Protagonist at the cost of her own life. Knowing how the Protagonist must feel he allows them to punch him, though he expresses that they will be destroyed when that happens. However, Romani Archaman interrupts them both and reveal his identity as Solomon, much to Goetia's disdained shock. Expressing that Solomon is too late to stop him Goetia prepares to kill him, but Solomon activates Ars Nova, removing Goetia's immortality. Though initially shocked at Solomon destroying his own existence, Goetia quickly becomes enraged and prepares to kill everyone.
