Shortly after the second season, Batman and Amphibian Woman frequently collaborate on the ground with Azrael to keep the peace in Gotham. Their first challenge is a former soldier notably targeting the city police and other political infrastructure for their non-help of former soldiers like him, calling himself Liberty Soldier. Next, they face an old-school supervillain, an old enemy of the JSA, coming to Gotham after decades of being missing : Count Destruction. Then they face other new super-mercenaries, in particular the terrible Belgian Obsidian Rider, who is truly indestructible, but discovers the identity of the new kingpin of crime, calling himself Devil Face, whom they will have arrested with his men. But in the end, all their efforts may well be wasted, given that Yushiro Al Ghul and his "League of Warriors" members cause a mass breakout in Arkham, taking several supervillains with him in his scheme to get revenge on his father. Despite all their good intentions, it could be that Batman and his acolytes are not enough this time...
