Peak Human Metabolism: Batman's natural healing, metabolism, immune system, are at the highest limits of human potential, which means he can heal much faster than normal humans, he is able to heal broken bones, fractures, torn muscles, gunshot, knife, puncture wounds and other major injuries all within a few weeks and minor injuries like cuts, scrapes and burns within a few hours to days. His immune system fights off microbes, infections, disorders, illnesses, sicknesses far better than normal (but is not immune). His healing time is very short, as he recovered from a broken back within an unknown amount of weeks.
Despite this, Batman has proved to have a great love for humanity, which was instilled by his parents. His father was a doctor, while his mother was a crusader against child abuse. Indeed, Batman's oath of vengeance is tempered with the greater ideal of justice. He refrains from killing, as he feels this would not make him any better than the criminals he fights. He is also a very prominent member of the Justice League and the founder of the Outsiders.
Joker, however, had discovered the ruse sooner than he expected and followed him to the pool. Having already retrieved samples to create a cure to the toxin, Batman fought his arch nemesis for what seemed to be the last time, during which he and Joker sustained several grave injuries. With the cave collapsing from explosives set off, Batman stopped Joker from escaping by holding him away from the pool, which was blocked with the falling rock. With Gotham once again saved, Batman accepted that he would die and sent one last message to Julia, during which he refused her help to escape his fate. He and the Joker would seemingly die as the cave collapsed upon them.
While the Crime Syndicate imprisons the Justice Leagues inside the Firestorm Matrix, Batman, Catwoman and a critically injured Cyborg escape in a sewer system and go to S.T.A.R. Labs. There, they find Doctors Silas Stone and Thomas Morrow. As Batman and Catwoman explain their situation, they discover the Crime Syndicate has taken over the world and revealed Nightwing's identity. Batman decides to find Nightwing.
Lorna Shore: In the Batman Confidential story Lovers & Madmen, Bruce met museum curator Lorna Shore during the beginning of his career. It was love at first sight as Bruce was able to find peace when he was with her for the first time since his parents' murder. However, after his encounter with the Joker and realizing that there would be more enemies like him, he broke off their relationship to protect Lorna. Lorna later left the city, feeling that Gotham wasn't safe anymore because of Batman and The Joker.
One of the first suits we see from Christopher Nolan’s Batman Begins is Bruce Wayne’s League of Shadows training garb. While mostly built for ease of movement and warmth, the uniform also includes the armor bracers and triangle blades which are present in most bat suits, which is why we count it as a prototype of sorts. This was a great suit because we got to see that Bruce was obviously taught how to use minimal weapons and tricks, but could if need be.
