 * Chaos Darkness is the one of the only monsters to have goodness inside of it.
 * Chaos Darkness's costume was a modified Chaos Header Everlease's costume.
 * When Chaos Header 0 first appeared and left he bore a distinctly angelic but masculine form and voice. However in Ultraman Saga Chaos Header had a much more feminine body and behavior. This was done on purpose by the designers to invoke the image of a goddess.
 * Chaos Header is the only known final antagonist in an Ultra series to turn good at the end.
 * To differentiate from his original counterpart, Chaos Golmede has a row of pink horns and a head crest on the top of his head. Also while the original can spit fireballs, Chaos Golmede can fire a yellow energy beam from his mouth.
 * Chaos Jirak's roar is a reused Gagi roar.

 * Chaos Ultraman is unique among evil and imitation Ultras, while not being a true Ultra he is still a being of light as he is a Chaos Organism clone of Ultraman Cosmos.
 * He is also the first Evil and Imitation Ultra not to use grunts but instead roars.
 * The main reason why did he imitates Cosmos' Corona Mode instead of Luna Mode because Luna Mode means calm while Corona Mode means agressive which mirrors Chaos Header's nature.
