Maven was Selina Kyle's best friend and secretary.
History[]
She knew about Selina's activities as Catwoman, but, out of loyalty, never said anything about it.
Maven worked with Selina for several years and the two shared a strong bond. Selina decided to don a costume and stalk the city as Catwoman, Maven assisted her and helped Selina maintain her secret identity, taking care of the details of her everyday life. Unfortunately, her affiliation with Catwoman got Maven into trouble with Red Claw, who wanted to contain the security risk that Catwoman represented to her operations. As such, a hired thug attacked her and if it weren't for the timely intervention of Batman, she would have been killed.
Maven continued to serve Catwoman even after she had been taken to jail for her crimes, and stood by her during her time in prison and subsequent release and probation. Unfortunately, she had accidentally left a window open allowing Isis, Selina's favorite cat, to escape into the city where she was captured and infected with a virus that Roland Daggett planned to release into the city. After Daggett was foiled, Maven assured Selina that Isis would turn up, which she did. Maven never appeared again since then.
