A team led by James Olsen/Guardian operates in National City of Earth Thirty-Eight. The team protects National City from anyone who means to cause it harm. It consists of Lyra Strayd and formerly Winn Schott. It also works with the D.E.O. and Supergirl's team, which are the team's biggest allies.
James's camera gets destroyed by criminals who obtained alien weaponry supplied by Cadmus. Winn tries to make a suit for him if he stays out of being a crime fighter until it is ready.
They get their third member of the team after Winn enters a relationship with Lyra Strayd. Winn wishes for her to join the team. However James doesn't believe it would work out due to her criminal actions in the past. However it ends up working and she then becomes a new member of the group.
