Cassandra Cain
Cassandra's superiority in combat results not just from her excellent physical condition, but from her cognitive functions (the result of her idiosyncratic upbringing) that enables extraordinary feats of coordination as well as perceiving minute changes in an opponent's movements and body language. In "Batgirl" #14 (May 2001), the writer, Kelley Puckett, places Cassandra in a position within the story in which her skills are analyzed by a group of government experts. The creative team reveals to the reader that the character has no metagene. Yet her genetic status was felt to be incompatible with her recorded abilities. One expert states, "Her individual moves are borderline human. It's her aggregate speed that's metahuman. Look—humans can throw a 100 miles-per-hour fastball, smash concrete blocks with their heads, and run 4.2 forties. What they can't do is all of that at once. It's not so much physical as... as mentally impossible. Too much to coordinate."
