Bio: When Luthor was sent to prison for the things he revealed to
a then in disguise J'onn J'onzz, Mercy Graves took over Lex Corp. One
had to wonder why she was chosen--but simply put, she was the only one
Luthor could trust to give it back. When he returned, asking her for
help when his suit began to malfunction, she helped him for a bit--but
it proved futile and he was packed away to prison. Again, he called for
help; but this time, she didn't give it.
