New Villians for Smallville Season 8

Since Michael Rosenbaum is only going to be a guest star next year, Producers and Writers from CW hit show Smallville are bringing in New Villians. One villian is going to be Doomsday, who is most known for killing Superman in Superman Doomsday (ie: comic book). The second villian they list is a girl who fans are very familiar with, they didn't give a name. I honestly don't know who it is. And it's not Wonder Woman, she's not a villian. I honestly cannot think of a female villian right now at 10:34am.
