EVERY month is WTF Month when you're dealing with...the Sorceress Of Zoom!!

The Sorceress and cohorts are pursuing Mu The Mystic, because he's stolen a young couple that she wanted to steal...

OK, that is one weird looking bat...

Really, that's a bat?

Well, whatever it was, it ain't no more!!

DO NOT MESS WITH THE SORCERESS OF ZOOM!!
