Aeon is a character from Konami's Castlevania series. He appears in Castlevania Judgment as an original character.
A mysterious character who appears in the "Time Gap" that serves as the stage for our story. He is the key to escaping from it. He is well-spoken and acts as if he sees through everything.
Aeon is a member of a group that watches over and preserves the flow of time. Since Galamoth seeks to take Dracula's throne by erasing the time that he lives in, Aeon goes into action to correct the disturbance to the flow of time, gathering the 13 soul keys and using them to find a chosen warrior to stop Galamoth's messenger, the Time Reaper.
In the Legacy of Chris Thorndyke, he is a member of the Council of Light along with Saint Germain and a keeper of time to make sure the timeline doesn’t get altered that would result in the world being destroyed.
And he is reprised by Erza Weisz in the English dub and Hiroshi Kamiya in the Japanese dub.
