Joe Wilson, also known as Kane Wolfman, is the leader of the Jackals and a former agent of the Australian Secret Intelligence Service. He is the son of Slade and Adeline Wilson, the brother of Grant Wilson, and the godson of the late Billy Wintergreen.
In 2004, Joe went camping with his father in Milford Sound, New Zealand. He found some flat ground and pitched his own tent. That night, his father cooked some fish, despite Joe claiming to not like it. Deciding he wasn't hungry, he went for a walk. The following day, the two of them threw a football around. Another camper, "Darryl", walked past with his family. Slade had Darryl take a photo of him with his son, before he and his family left. For lunch, Joe tried some fish, which he decidedly liked. He continued eating it while his father claimed to go to the bathroom, while he was really going to kill "Darryl", who he'd deduced was a secret agent named Sen Ming. Not long after, they left Milford Sound to return home.
Following in his father's footsteps
When his father went missing during the mission to Lian Yu, Joe went on to follow in his father's footsteps, joining the Australian Secret Intelligence Service, finding himself in the Republic of Kasnia, taking a new name, "Kane Wolfman". Found in the wrong place at the wrong time, Joe was imprisoned. However, he was soon freed by the Jackals, becoming their leader.

Behind the scenes
- Joseph William Wilson first appeared in the DC comic series Teen Titans, appearing in issue #43, as the mute superhero known as Jericho. He would later become an on-again, off-again villain to the Titans, due to assorted reasons.
- In the comic book continuity, Slade Wilson had three children: Grant, Joseph, and Rose. Rose is the only one of his children to have not yet appeared or been mentioned in the Arrowverse, most likely because of another Slade-trained female that took the codename and costume of Ravager on the show, Isabel Rochev.
- The name Kane Wolfman has a nod to two things. Kane is a nod to his Joe's mother's maiden name while Wolfman is a nod to Marv Wolfman, who created Deathstroke.
