A Champion that uses fog-of-war as their mana bar/ A parkour Champion

I thought this would be a new way of being able to incorporate a new game mechanic. Was trying to think of a way to use this on a champion and instead decided to throw it out to the public to see what kind of ideas there would be. The parkour champion was also another design I thought would be interesting and had the idea of twins that throw each other over walls or at champions.
