It tells the story of Katrina Cupertino (Cybernary), a cybernetic anti-heroine carrying the consciousness of Yamiko Gamorra.

Cybernary began as a backup story to Jim Lee's run on Deathblow,[1] but Manabat's work on the series was cut short with his untimely demise due to a longtime illness.

"[2] A second Cybernary, based on Yamiko Gamorra herself, was created in a short story written by Tommy Yune for the Wildstorm Thunderbook that overlapped with some of the events of The Authority.

After the World's End event, the Yamiko-Cybernary is able to make her way to the now floating island of Gamorra, trying to enact vengeance over her long lost father.

After having subdued Hawksmoore and taken him to Gamorra to be tortured by her father, her prisoner eventually escaped into the city itself since being in the last urban environment on earth had healed and strengthened him.

Some time after an invasion by the Knights of Khera, Katrina somehow regained her cyborg additions, as noted by the antlers and outfit she sported as Cybernary.
