While we're on topic, I'd like to elaborate a little on the following characters in Fate/Zero, specifically on the Servants. As a history faggot, I find the concept of incorporating "Heroes of the Past" into celestial summoning to battle amongst themselves for dominance of the sacred Sangreal (Holy Grail) the epitome of my wildest fantasies realized in animation form.
Thus, its only just if I "spoil" a few details about the Servants, and their "True Name", the hero associated to their respective class. Of course, you could read this all up in the Type Moon Wikia thats available for all to view and edit, but my hands are itchy to write a condensed version (and I'm procastinating from my assignment deadline), so why not.
Known as the best class among the seven Servants, Saber has high ratings in all categories of combat and skill as they utilize mostly melee weapons and their agileness to wear down their opponents; by getting up close and personal, fast.
Throughout the Fate/Zero and Fate/stay Night arcs, there is only one hero associated to this class;
Servants of this class are naturally blessed with their superior speed and powerful Noble Phantasms. Their trademark talent throughout the Rider class is the Riding ability; the skill to fully utilize any mounted object, be it war chariots to modern transportation or divine creatures.
In this time line,the True Name of Rider is;
Hailed as the strongest and most dangerous class in the Holy Grail Wars, Berserkers are generally incarnations of heroes whom have gone "berserk" at one point in their lives. By using Mad Enhancement, all Berserkers may opt to lose their sanity for a power up, giving them superior strength in battle while obeying their master's orders.
The Berserker in this war is closely related to King Arthur as;
Servants summoned as Casters are highly knowledgeable and adept in magecraft, their forte over other classes. Their special ability, Territory Creation allows Casters to alter their space around to enhance their sorcery.
As one of the three Knight classes, together with Archer and Saber, Servants in this category are skilled in long-range melee weaponry such as spears and lances to compliment their superior agility in combat. Most Lancers are heroes from folklore that have used such weapons in the past.
The only class among the seven to be bound by a rule when summoning them. This rule only allows 1 of the 19 original Hassan i Sabbah, leaders of the clans of Hashshahshins, to be summoned from the Assassin class due to the fact that evil Heroic Spirits (such as mass murders) may not be called upon. However, the Assassin in Fate/stay Night was an exception due to the fact the summoning was by Caster, another servant.
Servants of this class are exceptionally proficient in projectiles and long-ranged weaponry. As one of the three Knight class, Archers could survive longer without their Masters nearby or even alive, due to their special ability, Independent Action, which allows them to retain their physical form without a supply of prana, the power source of magecraft.
