Luke Cage is using his open hand instead of a closed fist. It's a little disrespectful but it's very effective. Some people call it a pimp slap, we call it smack-fu. He's doing you a favour by hitting you with an open hand. It hurts, it renders you unconscious but you live.
Mike ColterWhat I enjoyed about being in the world of Jessica Jones, as Luke Cage, is that I wasn't front and center because it was Jessica Jones' story, but it allowed me to find the character from a different perspective.
