Starting from Zero (sep 2, 1994 – oct 1, 2005)

Description:

The Zero Hour was the first Crisis that solely affected the timeline, having nothing to do with the Multiverse. In the aftermath of Hal Jordan's depraved attempt to reboot the timeline in the way that he pleases, the timeline was indeed partially rewritten, with certain characters receiving new backstories and updated aspects of their character. Batman was given a light version of his treatment when his First Year on the job as Gotham's premiere vigilante was updated to suit more modern times. The Legion of Superheroes, on the other hand, received a far more drastic retcon, having their entire origin and backstory changed after the Zero Hour. Some characters had their entire nature changed, such as the Hawk Champions, who were all merged into one entity known as the Hawkgod. A few characters were even erased from history altogether, such as the Team Titans, a version of the Teen Titans from the distant future, as well as a version of Barbara Gordon's Batgirl from a parallel timeline.
