Victor Alexis Rivera Santiago (September 17, 1986 - July 1, 2010), better known by his stage name Lele "El Arma Secreta", was a Puerto Rican rapper and songwriter who composed multiple songs for Héctor el Father and Cosculluela.

He wrote many songs for artists such as Héctor el Father, Yomo, Polaco and Daddy Yankee, but went mostly uncredited with a few exceptions.

After the company dissolved, he recorded "O Me Pagas" (featuring Endo), a diss track towards Héctor el Father for allegedly owing him royalties for his work as a songwriter.

He later went on to work with Cosculluela in his newly funded label Rottweilas Inc., where he both wrote and recorded songs, most of them along with his partner Endo, and he went on to start recording an album as a rapper, while both writing and performing the tracks.

On July 1, 2010, Rivera's body was found inside a car in Trujillo Alto with 24 gunshot wounds.
