The literary multiverse has no shortage of would-be “heroes,” to use the term quite loosely. And when it comes to the wild and wooly genre of science fiction, it is practically a given that every story will feature some form of hero, antihero, or hero by default. Indeed, due to the flexibility of the genre, they literally come in all shapes, sizes, color, and species. Some are born of intergalactic royal blood; Others are constructed in cold laboratories out of wires, circuits, and steel. We’re going to attempt to pin down a list of the most compelling, original, and impactful protagonists the sci-fi world has ever known! Some you’ll see coming a light year away; others, hopefully, not so much… for where’s the fun in reading a list of names you already know? Enjoy!
