Los Matadores is, as the promo showed, a matador gimmick with the Colon’s re-packaged into new characters, possibly hoping the new push will re-invigorate them. According to Rajah, Primo and Epico will not be re-joined in the new gimmick by their former manager-valet Rosa Mendes.
However, there will be a third member joining them in the near future. Mascarita Dorado, a developmental talent, will join the duo some time after their WWE debut. Mascarita Dorado just signed a developmental deal with the WWE in April 2013 after wrestling for both AAA and CMLL in Mexico.
Primo and Epico will be renamed as well, and WWE rumors indicate that their new names should be Torito and Torlito, both of which the WWE trademarked a few weeks ago. There is no telling what Mascarita Dorado will be named when he joins the group.
The Los Matadores will join the still growing WWE tag team division, which right now sees The Shield as the champions, and teams like the Wyatt Family, Usos and Prime Time Players as the solid teams in the company.
