Hopefully non of them become the next Batman, although the mostlikely to become would be Damian but just for his desire to be like his father
Like, Dick definitely wasn't too happy being Batman
Jason it's just a no, I belive he would rather die again than become Batman
Tim I can see him being the second most likely to become Batman
I think Batman either dies with Bruce or Cassandra becomes Batman. What? She's a girl and it's Batman? That's not relevant silly, she would be Batman
