The only member of the core members not to have a Sinister counterpart. Introduced in Defenders #112 (1982) by J.M. DeMatteis and Don Perlin, Zarda hails from the peaceful society island of Utopia. One day she encountered a shipwrecked sailor, Howard Shelton, who told her stories of WWII, so she went with him to fight with the allies. After her race decided to leave Earth, she remained and joined with other heroes to become the Squadron Supreme. She married Howard but while she would remain young, he aged regularly and eventually died. She would eventually begin a relationship with an evil Hyperion (the Earth-616 version) before the real Hyperion eventually killed him. She was worried about her feelings for the imposter but soon began a relationship with the real Hyperion.

She was eventually recruited into the Exiles and would lead the team in their pursuit of Proteus. She was eventually replaced by Prime Psylocke when she decided to return to her home world. After the Secret wars and the restoration of the multiverse, her world was destroyed with her being the only survivor after she was sent into another world by Hyperion. There she encountered an evil version of herself, and the pair would find themselves on the Prime Earth. Because the evil version had betrayed herself and stole her identity, she began investigating the Prime universe’s version of the Squadron Supreme.
