Nightmare Vira is the Nightmare counterpart of Vira.
Nightmare Vira was born at exactly the same time as Vira. She is twice as evil, but shares the job of an assassin and the desire to kill. She wishes that she could rule the Nightmare Dimension instead of Nightmare Tak, but heard what happened to Nightmare Ark after she tried to overthrow her, and remained a loyal member of the Nightmare Irken Empire.
