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. He is survived by a wife, Liza Rios, and three children. Big Pun was the first solo Latino rapper to sell over one million LPs. His first stage name was Big Moon Dawg. His name comes from the Marvel comic book anti-hero The Punisher.   Wikipedia
