Big Daddies

This is a Big Daddy from Bioshock. As far as things that try to kill you in video games, Big Daddies are definately my favorite. They have two types throughout the game, one with a drill arm (called a Bouncer) and one with a rivet gun (called Rosie). Almost everyone I know likes the one with the drill arm, as do I. You never really expect a thing in a diving suit to be able to attack you with a drill attached to it. You also don't expect a little girl to be leading it around calling it Mr. Bubbles, but Bioshock makes it seem commonplace down in the underwater city of Rapture. As far as the design goes, I can't think of many ways to make it better. It's size makes it an intimidating enemy, and lets you know that if you make it mad, there's a good chance you'll die. Although since you have to kill them to get at the Little Sisters leading them around to get better skills in the game, you have to deal with them. It makes them an extremely fun enemy because they're challenging, and after you defeat an enemy that has 300 pounds on you, you feel accomplished. That makes Big Daddy's an excellent enemy.
