The Rat Bastard

Eeeeviiiiil.

The one everyone loathes, and he feasts on that spite for him. He's fueled by hatred: the more people who hate him, the more power he gets from it. Of course, The Rat Bastard would do evil things intentionally; he does this for the lulz or he wants to be forever remembered for his infamy.

Sometimes, The Rat Bastard might get his comeuppance by having one of his schemes screw up and backfire horribly, damaging his wealth (as he's almost always rich) or business (as he's commonly an owner of at least one company). If things really go south for him, the Bastard might have some things get physically damaged, like having his home get blown up.

The Rat Bastard is similar to The Villain, but isn't always the main antagonist. If Villain enjoys making people suffer and derives joy from it, then they're a Rat Bastard.
