There's a story (see link below) showcasing the new costumes for the 'Superman Heroes', which includes Superman, Supergirl, and Superboy. It also talks about a backup story with new costumes for Power Girl and Omen/Lilith Clay.
I wasn't aware that Lilith was connected to Superman. When did this happen?
