The Quaxs Trading Centerfantastic Max animated series Harley Quinn is set in its own separate version of the DC Universe where the violence is frequent and the raunchy jokes come at you fast.

Harley Quinn recently returned for a new season, so we decided to revisit our conversation about the series.
