Zachs Darkness

''"You really can't expect me to save you." - ''Zachs Darkness manifested in his body.

Zachs Darkness, or darkside, is revealed when he gains his first power from two of the 15 Keys, coming to be during the chapter after Zach gains the Boost and his weapon. As of yet it only occasionally manifests to show Zachs rage towards a person or situation, and has not impacted the story significantly. Hopey points out that it has enough free will to become its own person.

NOTE: Zachs Darkness has the voice of a female in all manifestations.
