Assassin (アサシン, Asashin?) is the Assassin-class Servant able to be summoned by the Protagonist in the Grand Orders of Fate/Grand Order. He also appears in Fate/Prototype: Fragments.



Assassin's True Name is Henry Jekyll & Hyde (ヘンリー・ジキル&ハイド, Henrī Jikiru & Haido?). He is the character that appeared in the novel of 19th Century, "Dr. Jekyll and Mr. Hyde", or maybe the individual who became its model. It has been said that he attempted to detach "evil" from his own personality, but instead revealed a personality that embodied "evil", eventually performing murders and in the end self-destructed.[1]

FGO Assassin Dr Jekyll scene



A dual-existence that changes even his body as the personalities switch over.[1]


His original personality is that of a sincere and rational good man. To deeply think about things is both his merit and demerit. In contrast to his calm appearance, he has a strong sense of justice and was distressed by the "evil that lurks inside humans" while alive, having fought against it.[1]


  • Hyde

A hedonist without sense of morals, the "evil" personality. An anti-hero of malice that reflexively attempts to injure everything. It is unknown whatever evil really lurked inside Jekyll's heart, or if "it amounted to only this much" due to Jekyll being destitute of evil.[1]


Fate/Grand OrderEdit

He appears in London 1888.


Jekyll is of the Assassin class, but turns into Berserker-class Hyde upon using Dangerous Game. Maybe due to being summoned as an Assassin, or maybe because of the Master he lost in a previous summon, Jekyll is currently unable to completely suppress Hyde.[1] This incarnation of Berserker is different than when Jekyll is summoned as Berserker in that he retains his human form, as well as more of his sanity and reason.
