This girl is just nine years old, but we're pretty confident that she's going to be a real ass-kicker in either boxing or MMA in the not-so-distant future. Watch as she nearly CHOPS DOWN A TREE with her bare hands after pummeling it with punches! Crazy, right? Then, in the second clip, watch as she lands 221 punches in just 30 seconds. Sure, they're not the most devastating blows, but that's seven punches a second!
