 No previous ring identities have been confirmed for Barragán, but it has been stated that he made his professional debut 2005 and did not adopt the Aéreo mask and ring persona until 2010, which means he worked under other names before this, possibly even working for Consejo Mundial de Lucha Libre (CMLL) as one or several other masked or unmasked Mini-Estrella characters.Aéreo joined CMLL in mid-2010 at the same time as the company introduced fellow Mini-Estrellas Cisne and Pequeño Halcón, although Cisne only made a few appearances for the promotion.In his debut Aéreo teamed up with Pequeño Halcón and Último Dragóncito, losing to Cisne, Pequeño Violencia and Pequeño Black Warrior.
