Bionic Ninja Legs
In the pantheon of superpowers, one normally doesn't put "super legs" at the top. At first blush, it would seem fairly unlikely that this would ever be useful. But in reality, spider legs have a number of incredible adaptations. Spiders are designed for crawling, climbing, skittering and all-around creepiness. Jumping, not so much. Leaping about is more the domain of muscular-legged bugs like crickets and grasshoppers. Which is why it's all the more amazing that the spider known as Portia fimbriata can essentially catapult itself at prey. It can hurl itself up to 50 times its own body length (if you did it, it would be about 300 feet, or the length of a football field). That's farther than most grasshoppers can hop.
