Manuel Leal Navarro (born May 26, 1966), better known by his ring name Tinieblas Jr., is a Mexican Luchador enmascarado (or masked professional wrestler). He is the son of Manuel Leal, who wrestled for many years as Tinieblas. "Tinieblas" is Spanish for "Darkness".
Tinieblas Jr. made his professional wrestling debut in 1990, wearing a mask closely resembling that of his father Tinieblas.
During the summer of 2010, Tinieblas Jr. began working for a newly created wrestling promotion, backed by MTV2 called Lucha Libre USA, wrestling on their first television taping on June 19, 2010. On January 22, 2011, Tinieblas Jr. and El Oriental became the first ever LLUSA Tag Team Champions by defeating the Puerto Rican Power (PR Flyer and San Juan Kid) and Treachery (Rellik and Sydistiko) in a three-way tag team match. He later turned on El Oriental, winning the tag team title with Sol, although the controversial circumstances surrounding the title change led to the title being vacated. His last match for LLUSA saw Tinieblas Jr. team up with Lizmark Jr., losing to El Oriental and ÃÂguila.
