Trivia

 * Following Aria's death and betrayal of his father, Eden's hair permenantly changes from teal to a faded mint color. This is due to a common Japanese myth that extreme grief causes one's hair to turn white. His eyebrows do not change in color however.
 * Eden was the only Bronze Saint in the first season of Omega to not receive a modification to his original cloth prior to the second season during the Twelve Temples battle. Presumably, the enlarged gauntlet on his left arm would indicate his cloth had already been modified prior to the start of the series.
