I would’ve preferred that this joker would become the inspiration for Jared Leno’s joker in which Jared Leno is actually Robin before he turned bad somehow, which explains why there is HaHaHa on Robin’s suit taunting Batman and why that Joker isn’t that good. In a more crazier scenario, the original Joker who dies is delivered to the Lazarus Pit where he is brought back to life and is forced to work with Ra’s Al Goul to defeat Batman. That Joker meets Jared Leno and shows him the roes of what makes him a joker.
