Dr. John Watson

Dr. John Watson, ever heard of him? The guy's practically the Swiss Army knife of sidekicks. Without him, Sherlock's just a smart bloke talking to walls. Watson brings the human touch, making him essential in the 'Greatest Fantasy / Sci-Fi Sidekicks of All Time' league. Fans? Oh, they oscillate between adoring his patience and wanting to throw a Watson-themed party every time he actually gets a clue before Sherlock. It's like cheering for the underdog who already knows he's in second place but shows up with unmatched loyalty and a killer mustache.
