Echoing Effect (エコイングエフェクト, Ekoingu Efekto) is a sub-type of the ki-based effect "Aura of Fear". This technique is purely unconscious - an imprint of The Benefactor's ki signature is left on all planets he has ever visited. When Ledas absorbed some of The Benefactor's power, he was then able to see these visions of the alien on several different planets. It is unknown if The Benefactor could see any visions of himself, but it is unlikely.
