What are the best comics/comic runs out of those available on the app?
All of Batman Eternal is on here, and is a decent story. Identity Crisis is on here but I think it’s a short term feature so you’ll need to be quick if you want to read it. Legends of the Dark Knight #100 is a retelling of Dick Grayson’s origin and also has a Jason Todd Story.
The Teen Titans 2003 run is a really good introduction to the team with a really good story. Another good smaller series is Doctor Fate, really amazing art.
Batman and the Outsiders has all 32 issues. Legends of the Dark Knight.
