William Omar Landrón Rivera is the oldest son of William Landrón and Luz Antonia Rivera. He was raised in Santurce, a barrio of San Juan, Puerto Rico, specifically in the Villa Palmeras area. From an early age, he showed interest in the music of Vico C and Brewley MC, but never actually followed it. During his youth, he became an active member of a Protestant church, Iglesia Evangélica Restauración en Cristo, in Bayamón where he occasionally offered sermons. However, after four years, he left the church to dedicate himself to singing.

Several months later, he had his first public presentation in a night club, accompanied by disc jockey Eliel Lind Osorio. Afterwards he appeared regularly on compilation albums from popular DJ's and producers like Luny Tunes, Noriega, and DJ Eric. He also started working as a backup singer for the duo Héctor & Tito. One of the members, Héctor Delgado, helped him produce his first solo album.
