A re-imagination of the life of Alexander the Great based on the novel of the same name by Hiroshi Aramata, the series was produced by an international crew that drew from the resources of the worldwide animation community.

[citation needed] In the original attempt at American distribution, the producers created a dub under the direction of veteran voice director Jack Fletcher.

Only John DeMita would return to voice in the series under the alias Will Barrett, and would also take over the role of Alexander from Andrew Philpot.

There is also a theatrical version of Reign: The Conqueror, known as Alexander: The Movie in North America, which consists almost entirely of recut footage from the series, with the only new content being short opening and closing scenes.

The movie covers the first ten episodes of the anime, ending with Alexander's victory over Darius and the Persian army.

Desiring to attain 'speed', Alexander heads to the woods with allies Philotas and Hephaestion, where he tames a wild man-eating horse.

Macedonia heads to war with Athens, led by King Philip and his top advisers, Attalus, Parmenion (father of Philotas) and Antipater.

While Ptolemy is caught and suspended in the air, Alexander is able to save him from execution at the last minute by releasing all the horses in the city from their stables.

Philip holds a great ceremony to present his new prince to the masses and also constructs a huge golden statue of himself, declaring himself a God.

Around this time Parmenion reveals to Philotas a secret about Alexander, that prior to his birth Olympias proclaimed that he would destroy the world.

While in Egypt Alexander meets Dinocrates, a member of his army who tells him of the great city he'd prefer to create there, Alexandria.

The Macedonian army gains new strength when there is an eclipse of the moon, and the Plato-Hedron appears and ascends to the heavens.

Phillipas, secretly a member of the Pythagorean cult, plots with them to kill Alexander during his wedding to Roxanne through the use of a dancer possessing poison.

Elsewhere, Alexander is asked to get out of the light by a child drawing geometric shapes and writing formulas on the ground.

As Alexander walks off, it is revealed that the child's name is Euclid, and he pulls out a small version of the Platohedron.

The final scene depicts Euclid's Platohedron resting on the ground next to his diagrams, catching the sun's dying rays.
