Warning: This article contains spoilers for Harley Quinn season 3.

Harley Quinn and her eponymous animated series have come a long way in three years. 

When Harley Quinn premiered on the now-defunct DC Universe streaming service back in 2019, it began with the titular protagonist (voiced by Kaley Cuoco) finally breaking with her toxic boyfriend the Joker (Alan Tudyk) and trying to make it as a supervillain in her own right. That meant tangling with Batman (Diedrich Bader) and assembling her own crew of colorful characters.
