Caster (キャスター, Kyasutā?) is a Caster-class Servant able to be summoned by the Protagonist in the Grand Orders of Fate/Grand Order.



Caster's True Name is Charles Babbage (チャールズ・バベッジ, Chāruzu Babejji?), the King of Steam (蒸気王, Jōki-Ō?), a mathematician turned scientist from the 19th century who dreamed about the revolution of the world. He was known as a prodigious great scholar, employing a steam engine to invent the first computers in the world, the Difference Engine and the Analytical Engine.[1]

Although known as the father of the computer in modern times, he died halfway through his projects, leaving both machines uncompleted and having his envisioned future "vanish into the threshold of the eras."[1]



Caster possesses a strict personality, but displays a weakness towards innocent females and astute females.[1]

During life, he possessed a dream of a "possible future" that vanished with his death, but that future manifests with him in his current form.[1]

He wishes to use the Holy Grail for the "the advent of a world of steam civilization", but also feels that the modern world itself is not too bad after acquiring knowledge of it upon being summoned. He can be described as a "reliable ally" depending on the nature of his Master.[1]


Fate/Grand OrderEdit


Upon manifesting as a Heroic Spirit, Caster has become an existence close in nature to his Noble Phantasm, the Reality Marble Dimension of Steam. Sublimating the future of which he dreamed, his body is wrapped in the "possible future" in a "form of grotesque steel" and concealed in the "form of a grotesque world." Constantly wrapped in a "grotesque steam engine-made full-body mechanical armor", the Mechanical Armor skill grants a rank up to the Strength and Endurance attributes and bestows "++" modifiers to three parameters by means of a boost function brought about by the armor.[1]


Creation and ConceptionEdit

I-IV is the character designer for Caster.[1]
