A super-heroic crimefighter from the distant planet Trombus, who possesses superhuman powers nearly equal to those of Superboy. Hyperwoman, who is the mother of Kirk Quentin, alias Hyperboy, is a member of a supergroup known as the Hyper-Family, which is made up of herself, Hyperboy, her husband Hyperman, and Klypso the Hyperdog. Hyperwoman, like the other members of the Hyper-Family, only possesses superhuman powers under a red sun and is powerless under a yellow sun, the exact reverse of Superboy.
The Hyper-Family, under Hyperboy's direction, use Superboy to test whether or not their super-suits are completely indestructible and to assess their susceptibility to mind control (SB No. 144, Jan 1968: "Superboy's Lost Identity!").
