|~ Merlin about his incubus nature|
Caster is a Caster-class Servant that appears during the fifth and seventh singularity, E Pluribus Unum and Babylonian respectively.
Caster's True Name is Merlin (マーリン, Mārin), the Magus of Flowers (花の魔術師, Hana no Majutsu-shi). The son of the Queen of Wales and an incubus, he orchestrated the events leading up to Arturia Pendragon's rise as the King of Camelot and served as one of her closest advisers until the closing years of her reign. He left her service while fleeing from an "evil witch", entering Avalon on the Far Side of the World. However, he later finds himself trapped in a tower that only the innocent may exit, thus being imprisoned for eternity as he had long since transcended death.

Intelligence: Merlin is an incredibly powerful Magus and is considered one of the greatest Magi in existence, made evident by the fact that he's qualified to be summoned as Grand Caster. He considers himself on par with the King of Magic, a boast supported by his possession of Clairvoyance of the highest order, signifying his supreme mastery over thaumaturgy. His skill is such that Rin Tohsaka declares that exceedingly difficult tasks like changing Arturia's gender and arranging for Mordred's birth would be all but simple to him. He even managed to escape his own prison for the final battle against Tiamat. He is also a very skilled swordsman, having served as Arturia's sword instructor well into the early years of her reign. However, Merlin is also rather lazy and would opt to use Excalibur over his strongest spells to avoid biting his tongue during the long incantations.
Weaknesses: Merlin is laid-back, lazy, childish and rarely serious unless the situation is dire. He often bites his tongue during incantations and thus prefers to use Excalibur. He is somewhat full of himself and enjoys flaunting his superior magical prowess.
Garden of Avalon: The Forever-Sealed Utopia: Merlin's Noble Phantasm, in which he reproduces the “tower” where he is trapped in. It also reproduce its surroundings on the Far Side of the World. In such a mana-rich environment, Merlin is able to freely utilize his magecraft and Excalibur, while those of the modern age would literally burst upon breathing in this garden's air. In addition, anyone who has sinned cannot escape this area until it falls apart on its own, as only the innocent may pass through its gates.
- Excalibur: Sword of Promised Victory: Merlin also has access to the legendary sword used by his disciple, Arturia. The greatest among Holy Swords in existence, Merlin frequently uses it in combat in place of his magecraft. Despite his classification as a Caster, his time spent as Arturia's sword instructor allows him to wield it skillfully with a single hand. He can also call its True Name to utilize its devastating beam of holy light to obliterate his foes.
Item Construction: A skill which measures one's ability to manufacture magical items. Merlin only has a C-Rank in this skill as he's too lazy to construct particularly complex or powerful items.
Territory Creation: A skill which quantifies one's ability to create a territory advantageous to them as a Magus. Merlin is also too lazy to bother setting up complicated Bounded Fields or Workshops due to being imprisoned in the Garden of Avalon, resulting in a C-Rank in this skill.
Hybrid: A skill that reflects Merlin's heritage as a half-incubus hybrid. This trait is the source of much of his incredible magical prowess, being far superior to any human magus alive during his time.
Illusionism : The ability to cast and use illusions through Magecraft. Merlin is an exceedingly skilled practitioner of this art, allowing him to easily project visual projections of one's nightmares in the real world, he can even cover an area the size of an entire village in illusions. With Merlin's stellar A-rank he can even deceive the environment itself.
Dreamlike Charisma: A skill whose canon effects are currently unknown.
Hero Creation: An ability that represents Merlin ability to raise Kings, due to being considered the most prominent king maker in the world he boasts an EX-rank.
Independent Manifestation: Is a skill that allows Merlin to manifest independently in the current world. Although it is normally exclusive to Beast-class Servants, Merlin was able to give this to himself while he was "playing the part of the Master's Servant", allowing him to manifest projections while pretending to be a summoned Servant.
Clairvoyance: The ability that represents exceptional eyesight. Only Magi who possesses Clairvoyance of the highest order have reached the zenith of magecraft. Differing from the King of Magic who sees the past, present and future, Merlin possesses "Eyes that See Through the World", allowing him to view everything in the present era down to the tiniest detail.
