I made one for Einstein:
Archer is a heroic spirit who is able to be summoned for the Holy Grail War.
Archer's true name is Albert Einstein. Said to be history's greatest scientist, he revolutionized the field of physics and chemistry with many great achievements, most notably the creation of the theory of general relativity.
Personal Skills:
Pioneer of the Stars (EX): As one who solved many impossible questions and paradoxes, fixed many impossible theories, produced ideas that would be proved over 100 years later, and even brought forth a weapon causing destruction comparable to the Age of the Gods it was only natural that he would gain this skill.
Galvanism (EX): Using the legendary equation E=mc^2 this skill can surpass its prior limits and convert even attacks that possess a material form into energy. This allows for the production of immense amounts of energy from next to nothing.
Natural Born Genius (EX)
Imaginary Accuracy: Einstein once said "Imagination is more important than knowledge." This is Einstein's ability to always be correct even when everyone thinks he's wrong. Any conclusion reached will be the correct answer, even if it shouldn't be or seems illogical. Throughout his life Einstein arrived to many conclusions, hypotheses and theories which were deemed as incorrect or impossible by his peers, but they were always found to be correct.
Noble Phantasms:
Luminary of the Unknown (A+++ Anti-mystery): His discovery of many concepts has allowed for the elimination of much of the world's mystery. These discoveries are sublimated into this Noble Phantasm. When it's true Mae is spoken is, the bright light of knowledge shines outwards in all directions from Archer's body. All mystery will be removed from anything this light touches. Magecraft and supernatural abilities will cease to function, od and prana will cease to exist, supernatural beings will become humans or animals, Noble Phantasms and legendary relics will become normal objects. Even those that the light of knowledge does not reveal are not safe, as those who are not directly touched but still see the light will no longer understand how to perform tasks possible through mystery.
Annihilation to All: The Nuclear Bomb (A+ Anti-Country): when the true name of this Noble Phantasms is spoken, nuclear missiles rain from the sky towards the enemy. Upon detonation, an explosion and mushroom cloud that can be seen for tens to hundreds of miles will be created. Though Einstein may not have invented the nuclear bomb, he is one of those most heavily credited with its creation. These weapons would never have been possible without the theories and knowledge he brought forth. Due to the secrecy with which their creation, storage, and quantity is kept, these weapons possess a level of mystery typically impossible for a weapon of science. Though these are weapons that should not typically be capable of such power, in the modern day many people believe nuclear weapons to be capable of annihilating a country, misunderstanding the country ending destruction of morale, leadership, economy, and war potential as physical destruction. The wide-spread myths and misunderstandings surrounding these weapons has lead to them even individually being classified as anti-country Noble Phantasms.
Perfect Conversion E=mc^2 (EX Anti-fortress): This Noble Phantasm allows Archer to use energy absorbed through galvanism to accelerate drastically or strike an opponent with attacks containing a large amount of kinetic and magical energy. When this Noble Phantasm has its true name invoked all matter surrounding Archer is converted to energy and absorbed through Galvanism, this energy is used to propel objects, or even Archer himself, at such high relativistic speeds that they possess the mass of several buildings.
I figured his sheer fame should allow for him to be incredibly powerful as a servant. For the Personal Skills, I added the one I made cause I thought it fit him too well to not add, but I wasn't sure if I should get rid of Pioneer because of it. Any thoughts?
