Ninja nuns = Nunjas? :)
Batwoman and Nightwing (dressed as Batman) encounter a fortress heavily guarded by well-armed nuns in this clip from “Batman: Bad Blood.” Yvonne Strahovski (Chuck, 24, The Astronauts Wives Club) provides the voice of Batwoman, and Sean Maher (Firefly, Serenity, Much Ado About Nothing) voices Nightwing.
