I think that jason and damain are pretty much good, but I would switch Dick and Tim around.<<I think that Damian should be Hufflepuff and that Dick should be Slytherin. (And I agree with Tim being on Ravenclaw)
Here are a few different adventures with the Batfamily (Reversed Age). There are the Avengers, Teen Titans, Young Justice, The Kratt Brothers and other characters that I like in it. I'm also thinking about taking request for this.
