Witchblade! Unless we're thinking of something different. But in my Buffy comic, there was an ad for both of them, so that's the one I'm going with.

I still remember TNT yanking Witchblade with the official excuse, "We don't have the time/resources to make our own drama, so we'll just air other people's." Mumsy was sad. She still has my Witchblade graphic novels! Must rescue them!
