Every once in awhile, people ask "How old is [insert Titans character] supposed to be?" So I've created a page that analyzes this topic. Now, comic books, as a rule, have a somewhat sliding age scale. You can only age Robin and the original sidekicks so much - because as they age, so do their mentors.
But after examining all printed evidence, I've come up with some solid age theories. And it's all been adjusted for the ONE YEAR LATER event! Check out the Titans Age Page
