10 Things You Didnt Know About Nightwing
9. He Was A Secret Agent For Awhile
After the events of the Forever Evil storyline (we'll get to that), Nightwing ditched his vigilantism to pursue espionage.
Batman needed a set of eyes within Spyral, a spy organization that at the time wanted to reveal the secret identities of various superheroes. Extremely reluctant at first (exchanging fists with Batman over it), he eventually signed on and gave readers a relatively successful run as Agent-37.
What was interesting about this series is that one of its writers, Tom King, was an ex-CIA counter terrorism officer. This helped give authenticity to the stories involved and to what it means to live life as a secret agent.
