What if in the future, rather than cross her arms as Robin often does, she were to perform yoga techniques with her entire body, causing all manners of assaults to occur on an enemy. It's far-fetched, but I wouldn't mention it if it didn't fit so damn well. I could very easily see Oda drawing Robin doing Yoga positions whilst decimating enemy forces. By jumping between poses, she could develop her agility, and being able to contort would give her necessary dodging capabilities. Considering her ability is centred upon the body, fully utilising her body to access her full potential seems to make a lot of sense.
