==Summary==
Caster is a Caster-class Servant summoned by Fuhrer in the Imperial Capital Holy Grail Strange Story of Fate/KOHA-ACE, as well as by the High Priest Makuzu in the Sengoku Singularity of GudaGuda Final Hounoji.
His real name is Maxwell's Demon, a thought experiment created by James Clerk Maxwell that would violate the Second Law of Thermodynamics. His objective is to find a way to create a true perpetual motion machine with his Noble Phantasm. Under normal circumstances, he would not be able to be summoned at all, and does not even exist when summoned, due to his experiment still not being solved.

<tabber>
|-|Servant=Servant Physiology, Nonexistent Physiology (Type 1, possibly Type 2. As a theoretical being whose thought experiment was never solved, Maxwell is not even a Heroic Spirit and does not exist. This makes it so nothing in the world can even hit him, not even Servants that can interact with Kama. Only things that can destroy that which does not exist can kill him), Immortality (Type 1 and 5. Nothing in the world can kill him except attacks that kill even unkillable existences), likely Higher-Dimensional Existence and Abstract Existence (Type 2 Is a Demon, and thus should likely be a higher dimensional being. Demons are also born of human desires), Teleportation (Can teleport across Japan freely), Magic, Paralysis Inducement (Can use the magical energy generated by Maxwell's Demon to paralyse even Servants), Conceptual Manipulation (His Noble Phantasm is a conceptual type), Physics Manipulation, Law Manipulation, Temperature Manipulation, Energy Creation (Can negate the Second Law of Thermodynamics to generate infinite amounts of magical energy with a flawed perpetual motion machine), Absorption (Absorbs the life-force of children to activate his Noble Phantasm), Power Bestowal ()
|-|God of Makuzu=Superhuman Physical Characteristics, Higher-Dimensional Existence (As a Demon and a God comparable to the Buddha, the God of Makuzu is a higher dimensional being beyond space-time), Immortality (Type 1, 3 and 8. Is reliant on the reactor core within him that provides him his infinite magical energy), Regeneration (High-Mid, likely Low-Godly. Can regenerate from his reactor core, which is a Holy Grail. It was nescessary an attack that could sever dellusions and challenge the laws of physics themselves to actually destroy it), Darkness Manipulation, Energy Manipulation, Reality Warping, Law Manipulation, Conceptual Manipulation, Spatial Manipulation, Time Manipulation, Temperature Manipulation, Causality Manipulation, Soul Manipulation, Information Manipulation, Mind Manipulation and Memory Manipulation (Gained , can grant any wish a infinite number of times and should be comparable to the Holy Grail. Can control entropy), Resistance to Animal Manipulation, Elemental Manipulation (Fire, Water, Air, Electricity, etc) , Power Bestowal, Void Manipulation, Existence Erasure, Statistics Reduction, Curse Manipulation, Conceptual Manipulation, Size Manipulation, Probability Manipulation, Absorption, Clairvoyance, Precognition, Damage Reduction, Death Manipulation, BFR, Reality Warping, Time Manipulation, Causality Manipulation, Spatial Manipulation, Law Manipulation, Memory Manipulation, Mind Manipulation, Resistance Negation, Poison Manipulation, Energy Manipulation, Power Nullification, Light Manipulation, Aura, Disease Manipulation, Pain Manipulation, Statistics Amplification, Necromancy, Biological Manipulation, Absolute Zero, Age Manipulation, Soul Manipulation, Transmutation, Data Manipulation, Matter Manipulation, Information Manipulation, Gravity Manipulation, Life Manipulation, Fate Manipulation, Illusion Creation, Higher-Dimensional Manipulation, Fear Manipulation, Paralysis Inducement, Corrosion Inducement, Fusionism, Space-Time Manipulation, Sense Manipulation, Perception Manipulation, Sealing, Reactive Evolution, Reactive Power Level, Subjective Reality, Acid Manipulation, Chaos Manipulation, Physics Manipulation (As a being whose existence reached that of a God, he should be able to resist Authority with Authority of his own)

Attack Potency: Unknown (Maxwell, as a nonexistent being, is unable to attack or even produce any amount of energy at all); Large Island level+ (Can generate enough energy to endlessly create beasts capable of fighting Servants), theoretically up to High Universe level (Is a , although there are several caveats that make working with it difficult), likely Low Complex Multiverse level, possibly Complex Multiverse level (With the help of a Holy Grail, the High Priest Makuzu would have managed to fuse the Singularity it was in with the World itself. Created the Maxwell's Demon, the God of Makuzu, a being of unlimited power that had reached the level of the Buddhas and Gods) | Low Complex Multiverse level, possibly Complex Multiverse level (Is a being of capable of at will thanks to its infinite magical energy. Had reached the level of a God comparable to the Buddha)
Speed: Unknown (As a nonexistent being, he possesses no physical abilities), likely Immeasurable (Is a Demon, and thus likely higher dimensional in nature, just like other Demons) | Immeasurable (Is a Demon and a God on the level of the Buddha, and thus should be comparable to Kiara)
Lifting Strength: Unknown | Immeasurable (Comparable to the likes of Kiara)
Striking Strength: Unknown | Low Complex Multiverse level, possibly Complex Multiverse level (Can fight against the Bishamonten)
Durability: Unknown (His nature makes him nearly impossible to kill) | Low Complex Multiverse level, possibly Complex Multiverse level
Stamina: Unknown (Is a nonexistent being, likely does not even get tired) | Infinite (Is powered by infinite amounts of energy)
Range: Unknown, Thousands of Kilometers with teleportation, up to Low Complex Multiversal with Maxwell's Demon (Could erode the world with the singularity it was contained within) | Low Complex Multiversal (Can remake the World at will)
Standard Equipment: His Noble Phantasm, Maxwell's Demon | His reactor core, a Holy Grail
Intelligence: Likely Genius (Is a scientist Caster, demostrating incredible knowledge of thermodynamics and the laws of physics. Worked with Ryouma behind the scenes to set up the High Priest Mazuku, manipulating the Chaldea clan in the process. Created his Noble Phantasm, a reactor core that can generate infinite energy
Weaknesses: Can not attack enemies due to not existing except with Maxwell's Demon, a Noble Phantasm that requires preparation. Maxwell's Demon is a flawed Noble Phantasm that requires energy to create life-energy from children to work, and is most effective use is with preparation. Maxwell dislikes using his Noble Phantasm, and giving others its infinite magical energy may kill him. | Destroying the Holy Grail as his core would destroy him, although that requires an attack that can cut delusions and challenge the very laws of physics.
Notable Attacks/Techniques: 
===Noble Phantasm===
Maxwell's Demon: Negation of the Second Law of Thermodynamics: Maxwell's Noble Phantasm, it is a flawed perpetual motion machine that can create infinite magical energy, or at least, close to infinite magical energy. It is a paradoxical existence that requires several conditions to be activated, although in Fate/Grand Order, where it is powered by a Holy Grail. It was only necessary to use the life-force of several children to activate it. 
Using it in conjuction with a Holy Grail turned it into a powerful Noble Phantasm capable of summoning the God of Makuzu, a nigh-omnipotent being capable of granting infinite wishes and remaking the World as it is.
