But one night on the walk home his family was mugged and killed. The assailant (Joe Chill) decided to let the young Bruce Wayne live. His butler Alfred Pennyworth decided to be his Guardian and raised him. But two years later Bruce decided he needed to go. He left for five years and trained and studied in almost every fighting technique.

Bruce came back after five years to find the sick destroyed Gotham he used to live at. Full of crime and destruction, Bruce sickened and angered he dawned a cowl and became the Batman and vowed to clean up the streets in name of his lost loved ones.

Three years later Bruce found a protegee he could train to be the Batman for the fateful day of his Death. But due to the Flashpoint event, the timeline was messed up and his protegee quit and became the hero known as Nightwing.

After that he dawned several more sidekicks but the one after Nightwing changed him forever. His second protegee was named Jason Todd. He was an angered child like him but he was raised on the street. Bruce took him in as his own, but Jason soon found out the people who raised him weren't his biological parents. One night Jason found his Mother's location and went to her to find the Joker. The Joker brutally beated him and left him to bleed out. By the time Batman arrived he saw the building explode, and when the fog cleared he carried the deceased body of Jason Todd out of the building.
