Viper Mirage R (バイパ ミラージュ R, Baipā Mirajū R) is an attack used by Viper in which he sets up an illusion on the intended target and sets a specific rule in the target's brain, which, if broken, causes the target to be damaged with a wound to be determined by the caster: the two wounds shown so far have been lacerations and self-destruction. This attack appears to be characterized by a particular sound, and attacks the target's brain directly. However, the technique does not restrict itself to only one opponent, but on all people within a certain area, including the caster himself.
