3) A Battle With The Batman
After the mixed response to The Joker’s role in Suicide Squad (which was mostly caused by decisions made in the editing room it seems), the best place to redeem him may very well be in Ben Affleck’s upcoming solo movie for The Batman.
While rumours have pointed to that movie featuring several villains – possibly as the Dark Knight makes his way through Arkham Asylum – the Clown Prince of Crime being the lead bad guy makes the most sense, and it’s easy to imagine Jared Leto being able to really show off his stuff under the direction of a filmmaker like Affleck.
Those two butting heads as these larger than life characters would be nothing short of amazing regardless of the storyline. Ideally, Warner Bros. will adapt Under the Hood, a tale which revolved around the return of former Robin Jason Todd (who had seemingly been killed at the hands of The Joker years earlier).
Alternatively, just seeing The Joker causing chaos in Arkham as he attempts to take out Batman could be a lot of fun, especially if he brings Harley Quinn with him after the way things ended in Suicide Squad.
