Bruce Wayne (Earth-99)

"It's like a wise man once said: Battle not with monsters, lest ye become a monster."

- Bruce Wayne to Kate Kane

Bruce Wayne was the vigilante known as Batman. He protected Gotham City for many years before beginning a reign of terror in which he killed many people, including his universe's Superman.

Early Life
Bruce Wayne was born in Gotham City to an unnamed mother and father and was raised in a mansion. At an early age, his parents taught him that "life only makes sense if you force it to."

As an adult, Bruce decided to become a masked vigilante using the codename of Batman and developed a strict non-lethal code. He used a cave below his mansion as a base of operations and numerous bat-themed pieces of equipment such as a protective suit and car during his crusade against crime.

Reign of Terror
During his career, Batman became friends with Superman, to the point where he learned that his name was Clark and that he was vulnerable to green kryptonite and faced many enemies such as Clayface and Jane Doe, collecting many trophies from them such as a bloody playing card, a cane and a snow globe.

Despite his superhero code, he eventually ended up killing one of his enemies, which resulted in him becoming mentally unstable and killing numerous other people to the point where he lost track of how many he had killed. He also killed Superman in battle after coming to believe that he was a threat to humanity due to his superhuman powers and his deference to authority, keeping his glasses as a trophy afterwards. However, this battle almost killed him and forced him to wear an exoskeleton for the rest of his life so that he could move around. What had been dubbed as "Batman's Reign of Terror" by the Gotham City Gazette ended with Bruce barely able to walk and believing that there is no hope for the planet.

Afterwards, his cousin Kate Kane decided to become a superhero to succeed where Bruce had failed, but this resulted in her being killed and Bruce's mental state further deteriorating.

Crisis on Infinite Earths
Five years later, Earth-1's Kate Kane appeared at the entrance of Bruce's mansion after Kara broke down the door. He came down the stairs and asked Luke to stop pointing his gun at them before welcoming them into the house. Bruce took Kate to his study and stated that Clayface was a puddle of mud and that Jane Doe is locked in Arkham and so wondered who she was since his Kate was dead. Kate explained to him about the crisis and how he was supposedly the Paragon of Courage, but Bruce laughed at this and stated that he wasn't a hero and had lost count of the many people he had killed.

Later in his former base of operations, Bruce showed Kate the Batman suit which was covered in cobwebs and explained that it would not fit him any more and that even if it did, he could barely walk. Kate then stated that the multiverse was in danger and that she needed his help, but Bruce stated that he didn't care, as any world like his deserved to die. Kara then entered the cave and warned Kate not to trust him as he had killed this universe's Superman, but Bruce explained that he had to as he was giving too much power to anyone with a badge or a flag before punching her across the room with the green kryptonite inside his exoskeleton. Kate tried to stop Bruce from killing Kara and during the struggle accidentally pushed him onto an electric remote, which electrocuted him. Kate tried to help him, but Kara prevented her from doing so, as it would have killed her as well. With his final breath, Bruce told Kate that there was no hope.
