Biography

Height/Weight: 154cm ・42kg
Series: Back Alley Satsuki - Chapter Heroine Sanctuary
Source: TYPEMOON April Fools 2013
Country of Origin: Servant World
Alignment: Chaotic ・ Neutral
Gender: Female

A stranger visiting from a mysterious dimension called Servant Universe. Claiming to be the definitive version of the Saber class, an Anti-Saber Decisive Weapon that performs fair-and-square surprise attacks as a knight.

Code Name: A-X.

She uses the mysterious magical sword "Himitsucalibur" to exterminate all of her enemies.

The Artorian race is like cancer to the universe. Someone has to exterminate all of them. Someone has to.
Saying so with a bitter expression on her face, Heroine X left her hometown. Even today, her beloved machine Du Stallion II races through the sea of stars.

Unlike most servants, she wears an informal and sporty outfit. The blue scarf is a symbol of courage, while the hat serves to conceal both her identity and her cowlick. It sticks out-it sticks out-it really sticks out.

As an Anti-Saber Decisive Weapon, she normally goes into a carnage mode wielding her single holy sword for the sole purpose of defeating all present Sabers, but she has opened her heart towards Saber Lily alone.

Before coming here, she saved an ancient royal dynasty from a crisis, settled the internal strife of the Mankind Integration Union, and routed invaders from another universe, but, for her, that was akin to a snack before breakfast. Since it was so trivial, it seems as though she does not remember.

Until she achieves her truest, dearest wish, she shall continue to wield the Himitsucalibur. Also, no matter what, she will simply cut down the Golden Great Emperor Cosmo Gilgamesh.

She has not revealed this to anyone, but her true identity is that of Artoria Pendragon.

Trivia

  • She shares the exact HP values (at both minimum and maximum) with Jack the Ripper.
