- Main article: Anthology Characters
Anthology features 32 characters, in order to avoid having a character appear multiple times (example Scythe), other characters whom played secondary roles were chosen, despite this, Logan Atma is featured twice, as his character introduced in Omega V: Redemption is significantly different from his characters in Omega IX: Condemned. Some protagonists and antagonists were inverted in other games, for instance antagonist Albel Nox was a protagonist in Omega IV: Oblivion, there are other characters whose alignment shifted within the game such as Asch.
