In 1995 he began working for Asistencia Asesoría y Administración (AAA), initially as Baby Rabit but in 1996 he was given the name Máscarita Sagrada Jr., a mascota version of the Luchador Máscara Sagrada Jr. The name caused some tension with both Máscara Sagrada and Mascarita Sagrada as they felt the "Junior" was exploiting a character they made popular. On July 15, 1996, Mascarita Sagrada Jr. teamed with Mini Frisbee and Super Munequito to defeat Espectrito I, Espectrito II and La Parkita (II) at Triplemanía IV-C. On September 15, 1996, Máscarita Sagrada Jr. defeated Espectrito I to win the Mexican National Mini-Estrella Championship, winning AAA's top Minis title at the time.
