I haven't been regularly reading comics for a while, but I keep tabs on the events through comic book sites and social media. One aspect of the Batman mythos that I loved was the evolution introduced by Grant Morrison. Batman, realizing that he can be more of a force for good, broke his restriction of being just a protector of Gotham and started to promote resources for fighting crime globally. Thus, Batman, Inc. was born.

The Batmen of many nations was an old silver age idea that strangely works in today's modern era, thanks to Grant Morrison's reimagination. With the help of the main Batman, various vigilantes are made equipped with skills and techniques to help fight crime. It also enhances Batman's reach to other nations.

Batman, Inc. is basically an offshoot of Batman's Family. In the past, the very first sidekick he accepted was Dick Grayson as Robin. Over the years, numerous people have worn that mantle with the latest being Bruce Wayne's son, Damian. The commonly accepted logic is that the Robins are there to keep Batman from going overboard. Other theories about the logic behind training Robin that I love were: (1) Robin is Batman's plan for defeating him if ever he goes rogue (with their intimate knowledge of their father's abilities and mindset, the Robins are the best weapon againt Batman) and (2) Batman wants to harness angry young men into channeling their anger into fighting for good, rather than become vengeance driven like him.

In the past few years, since DC Rebirth, Detective Comics has followed the adventures of the Gotham Knights, a group that Batman assembled to help with crime in just Gotham City. The Knights recently splintered, leading to the changes happening. With Batman realizing he cannot control his proteges and allies fully to conform to his standards and ideals, he realized that the best he can do is teach them and guide them.
I think it's an important lesson for the Dark Knight and one that is intriguing to watch moving forward. While Superman is the symbol and inspiration, Batman can be the heart and motivation for the new generation of young heroes.
