@Riot: Thematically, what would you want to give a Dancer Champion?

It's no secret that I'd like to see a future Champion who is basically a dancer ala Fire Emblem, who supports their allies with their dance moves. But beyond a kit (which is for a different topic), what do you think would be most critical for such a Champion in terms of story, thematics, appearance, etc.?

My important values?

• Must be female (more flexibility and, yes, sex appeal)

• Should be lithe, limber, and have little trouble performing complex body movements
• Clothing should emphasize movement, even if it requires a lack of full coverage (i.e. shows skin)
• Nationality should be Shuriman or Ionian, preferably the former (makes the most sense)
• Dances should be full of spirit and liveliness (sorry, Orianna, but your ballet doesn't cut it)

What about you guys?
