Bio: A sweet, young girl stricken with amnesia, Annie met up with
Robin for the first time in an alley. After she ran away in fear from a
bunch of thugs, Robin tracked her down several times later to try and
help her figure out where she came from.
To both of their horror, Annie found out that she was not even human,
but an extension of Clayface. After Clayface had fallen into the ocean
and his body dissolved, he crawled up a drain spout where he sent out a
form of himself, Annie, to scout out the area and make sure everything
was clear. After being separated from Clayface for so long, Annie forgot
who and where she was, becoming lost and confused.
Annie remerged with Clayface in front of Robin's eyes, forcing Robin to
nearly go over the edge and kill Clayface. Batman intervened and pulled
Robin back. Despite not being "real", Robin couldn't help be feel hurt
after losing her.
