Fan Casting Matrix in Earth-27 fancast (rewrite)

A citizen of Kandor and childhood friend of Lor-Zod. After Krypton was destroyed by Brainiac, she was captured and immobilized. She had been cryogenically frozen by Brainiac as a means to archive the Kryptonian species and was now the female specimen of her race in Brainiac's menagerie. This prison/nursery experiment of Brainiac's contained children from a dozen other worlds, all nearly developmentally identical to young Thara. She was found by Sivana and she thanked him by joining the Salvation Syndicate as Superwoman, but later defected by Joining the JL as Matrix and she would be embraced and accepted by the Danvers family after Thara agreed with Alex to continue the ruse and and properly assumed the identity of Alex's deceased sister Linda Danvers.
