Assassin is an Assassin-class Servant able to be summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order, first appearing in the Saber Wars event.
Assassin's True Name is Mysterious Heroine X, also known as Heroine X and just X, an unknown heroine who tasked herself in eliminating Saber-class heroines during Back Alley Satsuki - Chapter Heroine Sanctuary. Bearing the code name "A-X", X was a stranger who came from the "mysterious dimension" called the "Servant Universe". Seeking to accomplish her "true, dearest wish" to "defeat all Sabers", she brandished Secretcalibur and left her home town, leaving behind an "expression full of bitterness."
X has revealed to none that her true identity is actually Artoria Pendragon. While she believes that her "perfect disguise" has tricked everyone, it is asked that others keep the fact quiet to keep from spoiling it and also for the sake of X's own honor.

Intelligence: Despite her class designation, X is just as proficient in swordplay as her mainstream counterpart, being specially equipped to defeat Sabers with two Excaliburs at once. She is pragmatic enough to call in covering fire to stun her foes and launch sneak attacks "fairly and squarely", massacring her targets without question (especially if they're Saberfaces like Nero). However, she seems to lack common sense and believes that her disguise is utterly flawless despite the fact that virtually everyone knows her true identity.
Weaknesses: Completely self-assured and oblivious to the fact that her identity is not actually hidden. The majority of her skills are targeted towards Sabers and other swordsmen, making her less suitable for fighting those who don't wield swords.
- Secretcalibur: Sword of Unsigned Victory: is the Noble Phantasm of Mysterious Heroine X. Normally wielding just Excalibur in her right hand, X summons Excalibur Morgan into her left hand and causes both to surge with power. She utilizes them as a rocket boost that blasts her towards the opponent. She slashes them repeatedly with both swords and then jumps into the air. As she descends, she shouts Excalibur, slashes with both swords in an overhead swing, and creates an X-shaped beam as she hits the opponent.
- Presence Concealment: The ability to hide one's presence as a Servant and the class skill of Assassins. It renders them difficult to detect through normal and magical means, making it suitable for spying on others but will reveal them once they start to attack. However, X does not believe herself to be an Assassin and instead sees herself as a Saber. Thus, this skill is currently sealed away due to her personal belief.
- Riding: the Class Skill of Rider and Saber, is the ability to ride mounts. Rider-class Servants will typically possess a high rank, and A-rank can allow for Phantasmal Beasts and Divine Beasts to be mounted. It is said that dragon type mounts are an exception, requiring a different ability other than Riding. Due to her EX rank, She cannot ride pretty much anything but displays amazing performance when steering spaceships, to the point that she can make them warp even if they are not installed with a warp function.
- Cosmo Reactor: A cosmic reactor allowed only to the multiplying Sabers. It is reacting to various things. Settings, for example.
- Back-Up Fire: A skill that reflects X's willingness to call in covering fire from her spaceship, the Dun Stallion II, to catch her foes off guard and stagger them before she moves in for the kill. In a one-on-one fight between fellow swordsmen, there are no unexplored territories nor soulful tactics.
- Galactic Meteor Sword: A special skill given to Saber that allows her to deal extra damage to those that fall under the Saber class, a skill that can otherwise be known as a "Saber killer".
- Instinct: The power to "feel" the course that leads to the best possible outcome in battle. X has a C+ Rank in this skill, considerably lower than the normal Artoria's. But only when facing a Saber does her instincts rank-up to A, allowing her to senses to match that of the normal Artoria's that borders on precognition and halving the hindrance that visual and auditory obstructions would normally provide.
