Just like Matt Murdock, Jeri is a lawyer who believes in protecting the innocent and striving for justice to triumph. However, rather than fight crime directly, he became an ally of the Defenders. She is closest to Jessica Jones, giving Jessica the cases that Jessica usually works on, but she is also close to Daredevil and Iron Fist.
As is common for a Netflix character, Jeri is aggressive and belligerent, and not afraid to break the law to protect the innocent, but still has a strong moral code, and a deep respect for the Defenders.
Jeryn Hogarth was created by Chris Claremont and John Byrne.
