Spock

Spock in 'Greatest Fantasy / Sci-Fi Sidekicks of All Time'? No contest. The man’s a Vulcan wonder with an eyebrow raise that could put your favorite comedian to shame. He's not just cool, calm, and collected; he's practically refrigerated. Fans debate not if he’s the best sidekick, but just how far the gap is between him and second place. And let’s not even start on the Vulcan salute – try explaining that hand gesture at parties without looking like you’re trying to start a shadow puppet competition.
