Robin

So, you're telling me you'd choose any other sidekick over Robin in the 'Greatest Fantasy / Sci-Fi Sidekicks of All Time'? Come on, the guy's practically a walking meme factory, flipping around in those hysterical tights, always ready with a 'Holy, something-or-other, Batman!' Sure, he might not have superpowers, but who needs those when you've got sheer, unadulterated moxie? Plus, every Robin fan knows the pain of having to defend his utility belt's contents at every comic con panel ever. It’s like defending pineapple on pizza, but way more serious.
