Myriad (program)

Myriad is a technological program created by Astra to "convert others to a way of thinking" (mind control). Astra first tried to use it on Argo City, which led to her and Non's incarceration in Fort Rozz. The only humans immune to Myriads affects are Maxwell Lord and Cat Grant, though some aliens where also immune, such as Kara Danvers, Maxima, the White Martian, and the K'hund.

Worlds Finest
At night, though unseen, this program was put into effect on every citizen of National City by Non and Indigo.

Myriad
Superman and every citizen of National City, except for Maxwell Lord and Cat Grant, are under Myriad's control.
