In the "DC Rebirth" relaunch, Orca and her Death Cycle are mentioned by Cheshire and Copperhead as some of the many villains who have attempted to kill Batman for Two-Face. Her first appearance is in Nightwing (vol.
4) #11, where she is a part of a criminal group in Bludhaven called the Whale's Enders and is ordered to kill Nightwing. Grace was formerly a member of the Run-Offs, a rehab group for former Gotham supervillains, but left because she considered herself too much of a monster to relate to them (implying that her transformation is permanent).
