Born and raised in Guadalajara, Rapder first discovered hip-hop at age 10, and became largely inspired by the likes of 50 Cent, Nas and Spanish rap group Violadores de Verso. He was introduced to the art of freestyle rap at the age of 15 by a neighborhood friend. “It's an up-and-down of emotions,” Rapder says of freestyling. “You're feeling your emotions, but you're also feeling your opponent's emotions.” Fans can witness these emotions in a documentary called Imparables: Red Bull Batalla, which is streaming on Red Bull’s website. The documentary offers an inside look at Batalla’s shift to a virtual competition amid the COVID-19 pandemic, and shows Rapder defeating Batalla’s reigning champion and becoming the world freestyling champion.
