In September 1969, the Grandfathers' spacecraft crashed into the Radio Crossbones ship. Along with Alan Scott, Wilde survived and was captured by the Ymir. On the threat of death, she acted as the go-between between the Ymir and their human prisoners. Mary worked with the Fifth Operational Corps to distract the Ymir while Anne Travers sabotaged the Grandfathers' ship. Wilde then helped get the prisoners out of the ship before it exploded.
