Hernan "Shades" Alvarez is a criminal arms dealer whose notable trait is his sunglasses on his face. He was an inmate at Seagate Penitentiary, where he and Comanche were enforcers to the corrupt warden Albert Rackham. Sometime after getting out, Shades went to work for Willis "Diamondback" Stryker, who later sent him to help out Cornell Stokes and Mariah Dillard. When Diamondback arrived in Harlem to kill Luke Cage, Shades stayed by his side even though his questioning of his boss' plans eventually led to him being fired from the crime cartel, forcing him to side with Mariah and betray his boss to save his own life.
Later on, Shades would negotiate a deal with Ward Meachum on behalf of Mariah to receive military grade uniforms and weapons from Rand Enterprises for her criminal enterprises, with Shades in particular gaining a set of S.H.I.E.L.D. optic visors to put in his trademark sunglasses for analysis and defense.
