Who needs Lena to go full villain when there’s an Agent Liberty on the scene?
Ruthless in the pursuit of his nefarious goals, Agent Liberty should cause plenty of trouble for Team Supergirl.
If Agent Liberty can sway public opinion against Supergirl and other aliens, their safety in National City and perhaps elsewhere could be very much in question.
Obviously we can’t say too much about the character until we see him for ourselves in Season 4, but it sounds like he’s going to be very different from his comic counterpart.
