The Batman Legacy

After witnessing his parents' murder at the hands of a mugger as a child, Bruce Wayne dedicated his life to training his body and mind to the peak of human capability, eventually donning the cape and cowl of Batman to wage a one-man war on crime in Gotham City. Operating from the shadows and armed with his intellect, detective skills, and an arsenal of gadgets, he became one of the world's greatest heroes and a founding figure in the DC Universe's superhero legacy.

This version of Batman appeared in the DC Universe amid the events surrounding The Flash, with connections to both Bruce Wayne and Thomas Wayne. Beyond that debut context, the specific identity and origin behind this particular Batman entry cannot be stated with confidence.
