Vandal Savage in issue 2. From declaring that a bunch of dragons bursting in is excellent since he hasn't eaten one in centuries to beating one dragon to death with another while shouting "Die, tasty rare creatures!" he's won a lot of people over.
Vandal is basically a walking CMOF combined with a walking CMOA in the form of a psychotic Boisterous Bruiser. Everything he says and does is pure gold.
When in hell, Savage's torture? To be poked by sharp sticks by the children he's never cared for, until he's forced to sign a document acknowledging his crimes. Eventually, he reads the document.
Savage: Oh. the mammoths. They were such noble creatures. Was I really the cause of their extinction? I suppose it wasn't their fault that they were so tasty. The Sacking of Rome! Oh. That takes me back... I have never drunk so much wine. But, my dear, it would have been wasted on the Visigoths.
