The following list comprises the various antagonistic factions that appear in the manga Saint Seiya and the sequel Saint Seiya: Next Dimension, written and illustrated by Masami Kurumada. The antagonistic characters appear as various deities from Greek mythology, who rule over the realms that form Earth, and their servants who form part of their armies created to wage war against Athena, the protector of the Earth realm. In addition, several factions aren't presented as soldiers of these armies, but as organizations who pursue their own ends.
