One of the best parts of Harley Quinn is its unique take on characters both beloved and obscure, and how they fit into Harley’s evolving narrative. Who would you want to see show up in the next season, and how would they relate to Harley? (And, bonus: who would you get to play them?)
Personally, I think Red Hood would make a great addition to the cast. Another guy whose life was ruined by The Joker and crashing his way through the Super-Villain system, but in a totally different way, could foster some interesting moments with Harley Quinn as she deals with similar personal and professional problems.
As for who I’d pick to voice him, considering this series’ heavy comedy background… Jay Baruchel.
