Strata is a Dryad who spent much of her early life as a slave to the Dominators. However, she eventually met fellow slave Vril Dox and joined his resistance movement. She soon escaped and fought against the Dominators during their invasion of Earth.
Strata was created by Alan Grant and Barry Kitson.
Vril Dox II invited Strata to join his newly formed interplanetary police force, L.E.G.I.O.N. She accepted the invitation and has since become one of the most devoted members of the team. In time, she met and fell in love with fellow Dryad, Garv. The two married and are living happily together. She is also a member of the interstellar police force, InterC.E.P.T.
