Christopher Rios (November 9, 1971 - February 7, 2000), better known as Big Pun or Big Punisher, was a Puerto Rican American rapper who emerged from the underground rap scene in The Bronx in the late 1990s. He first appeared on albums from The Beatnuts on the track "Off the Books" and on Fat Joe's second album Jealous One's Envy, on the track "Watch Out", prior to signing to Loud Records as a solo artist. Big Pun's career was cut short in 2000 at age 28 by a fatal heart attack due to his obesity.
