Here's the Season 2 description from their Facebook:
Batman has left Gotham City in the hands of his protege Nightwing, who must rise to become the protector of the city. The series, now in production of its 2nd season, places an emphasis on the characters behind the masks they wear and the significance of the masks themselves.
Rich with characterization, action, and nods to the comic books, the series has and will continue to feature appearances from Black Canary, Oracle, Huntress, Catwoman, the Riddler, and others.
