DC Comics recently showcased a merger of their two biggest heroes, Batman and Superman, in World's Finest. Their fusion created the "SuperBat," an idea that became an instant hit, prompting talk of future mergers. As interesting as the idea might be for more heroes, there's just as much potential when for villains to fuse, whether from DC, Marvel or elsewhere.
