1. Katniss Everdeen, 'The Hunger Games' series (2012 - 2015)
It's impossible now to imagine anyone else as the Girl on Fire. The rebellious gladiator of Suzanne Collins' futuristic novels may be the most complex action heroine in movies -- warrior, big sister, survivalist, media icon, revolutionary figurehead, traumatized executioner, and one leg of a teen love triangle.
Displaying all these facets, Lawrence's Katniss is compelling to watch in triumph but maybe even more compelling in failure. After all, she's still just a kid being asked to bear impossible burdens, and letting that anguished, fumbling humanity shine through is a Lawrence specially, too.
