Glory Griffin was a production assistant on the set of Second Skin Basil Karlo's final film. According to Karlo she was a fan of his and would often stop by his trailer between shots to talk. When Karlo attacked the production she tried to stop him from hurting the cast and crew by reminding him of who he was. According to Batman she was doused with chemicals during Karlo's attack, but according to Karlo he drowned her in the chemicals (he would in this same conversation talk about the memories of his time as a villain being hazy). Her interaction with these chemicals gave her body similar properties to those of Clayface, though she lacked the ability to control it. She would later become a member of the Victim Syndicate.
