Tom King (comics)
King was chosen to co-write "Grayson" for DC Comics, along with Tim Seeley and Mikel Janin on art. After penning "Nightwing" #30, King, Seeley, and Janin launched "Grayson" on May 2014, featuring Dick Grayson leaving behind his Nightwing persona at age 22 to become Agent 37, a Spyral spy. King and Seeley plotted the series together and traded issues to script separately, with King providing additional authenticity through his background with the CIA.
