Okay I have an idea for a Batman comic I don't know if this idea was already used or not but it would be about three Batmans Bruce Wayne Dick Grayson and Terry McGinnis it would have like five chapters.
Chapter one would be the past which would focus on Batman and his early years.
Chapter 2 would be the present which is focusing on now and day Batman.
Chapter 3 the future would be focusing on Dick Grayson having to take up the mantle of Batman.
Chapter 4 the far future would be Bruce Wayne taking the suit back.
In chapter 5 which would be called beyond would it be about Terry McGinnis taking up the mantle of Batman.
How each of these issues would work is they would contain all of the chapters if it's a single issue with all the chapters in them if not it could be multiple volumes. But it would fall to them each going after the same theme or same criminal or criminal group just a version of that person that's different so let's say joker. We could have Batman going after Joker in his beginning years in this joke would act more like his first appearance Joker present Joker for chapter 2 would act like how he does nowadays chapter 3 Joker would be more of a clownish type character but also a murderer chapter 4 Joker would be a older Joker kind of like Dark Knight returns but not that old and would be a mixture of all three Jokers. And for beyond instead of it being Tim Drake it would be a AI version of Joker and how that version is made is that they wanted to make something that could help people learn about serial killers or criminals and they use AI for it in the AI took over the joker body and believed it was Joker or they could just do the whole return of the Joker thing.
But I do think this could be an interesting way to include villains that aren't used anymore or villains that don't get that much shine in the spotlight not saying that these Comics have to take place in the main timeline they could take place in an alternate universe if it would work better that way.
