The story Should Auld Acquaintance Be Forgot, written by Alan Burnett, who was producer for most of the DCAU animated shows.
Deadman meets a young blonde woman, who was no longer in continuity, because she died in Crisis on Infinite Earth 7 and was erased from History.
Deadman is bemoaning his fate.
The woman states, “Listen to me. We don’t do it for the glory. We don’t do it for the recognition. We do it because it needs to be done. Because if we don’t do it, No one else will. And we do it even if no one knows what we’ve done. Even if no one knows we exists. Even if no one ever remembers we ever existed.”
That is the best definition of a hero I ever read.
Then she says, “My name is Kara. Though I doubt that’ll mean anything to you”
