Random Question: How old is Batman in Soul of the Dragon?
My headcanon for that has been that it could be the New Frontier (Earth-21) universe. Could be wrong?
ME TOO! In fact, here are the films I consider canon to eachother. I call it "Earth-Prime".
As for Bruce's age, it lines up perfectly.
New Frontier: Bruce Wayne is 23 in the beginning of the film, and 29 years old by the end of the film.
Soul Of The Dragon: Bruce Wayne is 42 years old by this time. Bruce Wayne has been Batman for around twenty years by this time, which means the flashbacks in this film are set sometime in the 1940s or early 1950s.
Dark Knight Returns: Bruce Wayne is Fifty-Five by this time. Bruce Wayne has been retired as Batman for ten years by this time. This means he retired in the year 1976, three years after the events of "Batman: Soul Of The Dragon". Superman mentions both Wonder Woman and Green Lantern: "
Diana went back to her people......Hal left the planet." It seems that The Justice League split up in 1976 as well due to the following dialogue: "
You know, we almost had this talk ten years ago when you wouldn't go along with the deal we made. Everyone else agreed. Diana went back to her people. Hal left the planet. And Oliver? Did he agree?"
JLA Adventures: The "present day" scenes must occur sometime before 1976 since "Batman: The Dark Knight Returns - Deluxe Edition" reveals that Batman and The Justice League retired by that year. It's likely they are set after "Batman: Soul Of The Dragon" due to Robin being absent from that film. So Bruce is in his mid-40s in this one.
