Batman: Arkham Exodus

Story
The second game in the batman prequel trilogy

Exodus meaning a mass departure of people, especially emigrants.

Taking place a few months after batman assault on Arkham where all the inmates escaped. Taking place during the winter solstice from dusk till dawn. A plan has been created to tear apart the batman not physically but mentally and spiritually. All of his villains are either working against him or ran off to other cities to steer clear of the war about to break out.

The game would feature the "death" of Jason Todd but only feature the joker briefly throughout the game a couple of conversations with him at the asylum until they free him to damage the bat in a way the bane or anyone else ever could.

The game will end with batman defeating joker and facing one last dangerous threat just like clay face was quite possibly killer croc except he will be more mutated then he was in origins and just as deadly as asylum, you won't be able to shock to get rid of him.
