The OMAC NW-00 is an OMAC unit formed around the superhero Nightwing by Brother Eye while he tried to infiltrate the Batcave: Outer Caverns. Having brought an EMP device into the Batcave: Outer Caverns with Robin, Batwoman and Huntress to release Brother Eye's hold on the security terminal, it is revealed that he, along with the other Bat Family members, have been secretly infected with the OMAC virus and are activated by Brother Eye in an attempt to prevent the player party from progressing further.
