Watcher's True Name is unknown, censored as ○○○·○○○○.Although described as a Heroic Spirit, is said to be an abnormal phenomenon that would be hard to call a hero, god, or demon. Upon its summoning, Enkidu senses an "abnormality" with his Presence Detection skill and wonders if he has "angered them a little," but does not believe it has anything to do with a Heroic Spirit being summoned.
The purpose of Watcher is not to act as Servant replacing one of the other classes. It is a "lookout" observing the Holy Grail War, and said to be an obstacle for Sigma to overcome so he can become "Lancer while living." It will give him "unreasonable" trials to overcome so that he can "become somebody."
The actual Servant has yet to appear. Its shadows speak to Sigma, appearing and disappearing to speak in turn.
The shadows profess that Sigma is unlucky in having summoned Watcher, that he is now burdened with unavoidable hardship. They have high hopes for him that he'll become Lancer. The shadows often speak of regret and hatred.
Sigma summons his Servant without a catalyst at the behest of Francesca. Upon the summoning being completed, he is greeted by Watcher's shadows, confused by their appearance. They mention that he is unlucky in having summoned them, but that they have high hopes that he'll become Lancer.
Watcher is not an actual Servant class, but they could potentially be properly summoned under the Gatekeeper class. The actual Heroic Spirit has not appeared, instead manifesting various Shadows (影法師, ?). They each appear one at a time, displaying distinctive appearances and personalities. Sigma sees the shadows as being like Heroic Spirits, two of them claiming to be able to appear as proper Heroic Spirits under other circumstances, but they are not Heroic Spirits in their current state as Watcher's shadows. Sigma cannot read their statuses like a normal Servants. They cannot use any Noble Phantasms, and lack anything that can be called a weapon, not a blade or even a chopstick. Like regular Servants, they are granted some information about the Holy Grail War from the Grail.
Sigma can feel his connection through magical energy to the actual Heroic Spirit, but it does not seem to be draining his magical energy. It starts watching the city immediately after summoning, noticing a "tear" in that Heracles was transmuted into the Avenger Alcides and other unnatural existences being drawn into the city. The shadows mention that Watcher cannot see into the past, only observing events since its summoning. Shortly after its summoning, Caster senses the feeling of being watched. Although noting has physically changed about his room, he feels "as if the quality of the space itself had changed." Although an uneasy feeling, he decides to pay it no mind and feels fine with an "audience" spectating.
The self-proclaimed Captain (船長, ?) is the first of Watcher's shadows to appear. He is a modernly-dressed, aging old man with gray hair and a large vertical scar that runs from his face to below his collar. His features are described as being "old enough to be called elderly" but also strong enough to give the presence of an active-duty marine. He appears in an old chair, carries a cane in his hand, and he has a distinctive smooth, white artificial leg attached at one knee.
He claims that as a proper Heroic Spirit that he would manifest as a class founded on vengeance rather than as a Rider. Upon sensing True Archer, he feels "presence like his own" and resonates his own rage with it.
"Boy with wings on his back"Edit
The boy with wings on his back is a self-described "escaped prisoner." Compared to the more modern looking captain, he is dressed more like someone from ancient myths. Upon his back and shoulders, he is fitted with mechanical wings, having degraded to looking skeletal with pieces of wax and white feathers interwoven throughout.
"Child with the serpent staff"Edit
The child with the serpent staff is a young boy in his early teens. Wearing a white garment, he carries a staff with a living snake entwined around it. He says his appearance of being a child is due to the effect of using his own body as part of a clinical study to test Medusa's blood.
There are many other voices not attributed to any specific speaker. One of the voices says it would have "materialized and made a go of it as a Heroic Spirit" if Sigma had been a woman.
