Echoing Effect

Echoing Effect is a sub-type of the ki-based effect "Aura of Fear". It is therefore a more advanced technique. Using it is rather difficult, because the user must perform the technique with the purpose of leaving it in temporary hibernation, until the time is right for it to be unlocked. And once performed, the original user does not know. So, really, the only purpose of this is psychological; a showcase of power and terror. To even leave an echo, one must have immense power and horror. In the Dragon Ball universe, the only character who meets this criteria is the Benefactor.
