Mysterious Heroine X (Alter) Alter is a Berserker-class Servant in Fate/Grand Order and a parody-influenced alternate member of the Servant Universe. She is presented as a quiet dark-side heroine trained in an organization opposed to Saber-class figures.

Mysterious Heroine X Alter in the Servant Universe

Reserved, sleepy, and strongly motivated by sweets, Ecchan has a calmer personality than her destructive class suggests. Friendship with Mysterious Heroine X complicates the roles assigned by their rival factions.

She uses the dark energy blade Cross-Calibur and abilities modeled on science-fiction villains and Arthurian references. Her Servant Universe origin distinguishes her from the main historical Artoria and other ordinary Fate timelines.
