The Fate/Zero Drama CD introduced an illustration with a number of unique designs that were also given specific details upon Ionioi Hetairoi's deployment in the anime adaptation. The members that make up his army include the Lord of War, the Maharaorajah, the founders of many dynasties, and even his horse, the legendary charger Bucephalus. He can also choose where to deposit them after releasing it, though only within one hundred meters. Their thunderous cries and their spirit could split oceans, and even someone as proud and haughty as Gilgamesh is left silent upon seeing such a radiant army.

They display the violence that reveals Alexander's method of tyrannical kingship without restraint, and he only takes pride in it.

They are his greatest treasure within treasures that make up his right to rule, and more than mere followers and soldiers, they are his true friends. They are able to break the rules of space and time to fight once more at the side of their king, and like him, they wager everything that they are on the king's dream. As a leader who only desired to become stronger and more magnificent, live more fully, and become a man more real than any other, he inspired them enough to leave upon them an impression of never-ending loyalty that not even death can conquer.

They swept across continents during life, and no matter what they faced, enemy or fortress, it was powerless before them. The entire fighting force is fully composed of a peerless array of famed and legendary warriors only heard reverently in legends, all of whom personally fought with Alexander on the battlefield. Once fully materialized, the heavily armed cavalry of soldiers slowly appears as mirage-like images and completely manifests as a diverse fighting force with the fierceness of a true army. It also maximizes the Charisma of the King of Conquerors Iskandar. This Noble Phantasm drags the enemies into a terrain that has no obstacles on the desert battlefield. They and their king recreate the land in which they once marched and shared many joys and sorrows, as it is imprinted upon the heart of each soldier, allowing them to bring about a sand-filled expanse roaring with hot and dry desert winds under the scorching sun and cloudless, clear skies without anything to obscure the everlasting horizon. It comes about through the combined efforts of his personal guard who all shared his dreams and pledged allegiance to him after many victories and defeats, even after death and becoming Heroic Spirits on their own as well. Normally, only a magus or something beyond normal reality like Daemons are capable of materializing the environment inside their minds, and as Alexander is neither, reproducing it alone is impossible for him.

It is an irregular Reality Marble compared to those used by others. Like how Saber's Excalibur can be called the physical actualization of her ideals as a king, Ionioi Hetairoi is the actualization of Alexander's commanding abilities and his kingship. The trump card of the King of Conquerors, it summons a Reality Marble that embodies Alexander the Great's dreams and philosophies as a king and the bond formed with his subjects, his life sublimated as a Noble Phantasm. It is described as the ultimate Noble Phantasm of Rider, a " super Noble Phantasm" as described by Tokiomi Tohsaka with the same rank EX-rank as Gilgamesh's Gate of Babylon.
