One way DC demonstrated the epic nature of its 12-issue limited series "Crisis on Infinite Earths" (April 1985 – March 1986) was through the deaths of important characters. In issue #7 (October 1985), Supergirl sacrifices her life to save her cousin and the DC Multiverse from destruction. When the Superman continuity was rebooted after "Crisis on Infinite Earths", DC editors felt that Superman should be the sole survivor of Krypton, resulting in Kara being removed. Unlike a number of other characters who are shown dying in the Crisis, no one remembers Kara dying or even ever having existed.
