==Characteristics==
Phantom Spirits are said to be "cast-offs," beings that were forgotten by history and are devoid of any faith. They are made up of urban legends, fairy tales, and extinct beasts.Fate/Grand Order: Epic of Remnant - Shinjuku: Malignant Quarantined Demonic Realm - Section 17: Truth's Cruelty Described as fictions whose concepts will never manifest beyond the status of urban legends, they are beings that will "wither and disappear," failing to attain the ranks of Hero or Anti-Hero.Fate/Grand Order: Epic of Remnant - Shinjuku: Malignant Quarantined Demonic Realm - Section 3: Monster that Tramples Around The National Highway Like Heroic Spirits, Phantom Spirits possess the capacity to hold Noble Phantasms based upon their legends. The same characteristics of some Noble Phantasms being weakened or strengthened upon becoming Noble Phantasms applies the same way to Phantoms, but they are always greatly weakened as a matter of course if one is summoned. 
Due to their poor Saint Graphs, Phantom Spirits are beings of low strength, weaker than author Casters whose fame come from writing stories. Appearing as Shadow Servants, they would not be worth summoning in a Holy Grail War.Fate/Grand Order: Epic of Remnant - Shinjuku: Malignant Quarantined Demonic Realm - Section 18: Great Detective's Great Deduction Attempting to summon one as a Servant under normal conditions, they would be unable to manifest with a body, and, without a body, would be unable to function as a Servant. They at most will appear in the form of ghosts, or they can be placed in something like a doll body.Fate/Grand Order: Epic of Remnant - Shinjuku: Malignant Quarantined Demonic Realm - Section 8: Empress Christine They lack the capacity to hold much magical energy, no matter how much is supplied, so they can store a minute amount. They are unable to actualize their Noble Phantasms. 
Phantom Spirits normally lack utility as Servants, but Baal's machinations in the Shinjuku Singularity lead to the ability to fuse them with Heroic Spirits and other Phantom Spirits. While said to be impossible outside the Singularity, utilizing data gained from it proves enough for Sion Eltnam Sokaris to summon Captain Nemo.Fate/Grand Order - Captain Nemo profile Akin to a Mystic Code for a magus, Phantoms can be transplanted into Heroic Spirits to enhance their abilities.Fate/Grand Order: Epic of Remnant - Shinjuku: Malignant Quarantined Demonic Realm - Section 1: Singularity Landing Point Through fusion and manifestation under a Servant's Saint Graph, the Noble Phantasms possessed by Phantom Spirits can be actualized, granting new abilities to the Servant. 
Phantoms are similar beings to Wraiths, but the exact differences have not been explained.
