In the Fate series, Servants are summoned into one of seven standard class containers - Saber, Archer, Lancer, Rider, Caster, Assassin, and Berserker. In addition, Extra classes were introduced throughout the franchise - Avenger, Ruler, Shielder, Alter Ego, Moon Cancer, Foreigner, Pretender, and Beast. Some other minor classes like Saver, Gunner and Faker are also present, but not enough information exists for them yet.

This pool is for fan-made designs of Servants summoned into a class container that has not been officially depicted in the actual series. Depending on what happens in the franchise, some of these images might wind up being Hilarious in Hindsight.
