MOST FEARSOME BOND VILLAIN
Blofeld is the easy answer because he's appeared in so many Bond films, and because he's the inspiration for the Dr. Evil character in the Austin Powers movies. And that ever-present cat on his lap ... that has to make him a truly, deeply bad guy. A dog person would never be hell-bent on global domination.
Francisco Scaramanga, the inspiration for The Man With the Golden Gun (1974), is also a tempting choice. He has a third nipple, people! What more do you need?
But I'm picking Jaws from The Spy Who Loved Me (1977) and Moonraker (1979), played by 7-foot-2 Richard Kiel. Those teeth — they could do some serious damage.
