Seven years after his Oprah Show debut, Rudy's back…and he's not so little anymore. Now 18 years old, Rudy kept a promise he made to himself when he was 7 by winning a 200-meter individual medley gold medal in swimming at the 2004 Paralympics in Athens—and set a world record in the process!

Rudy says his personal motto is "A brave heart is a powerful weapon."
