Jesús Alvarado Nieves ([xeˈsus alβaˈɾaðo ˈnjeβes] October 7, 1959 – April 28, 2017) was a Mexican luchador, or professional wrestler, who worked under the ring name Brazo de Oro ([ˈbɾaso ðe ˈoɾo] Spanish for "Golden Arm").

His nephews, Máximo Sexy and Psycho Clown are featured wrestlers for CMLL and Lucha Libre AAA Worldwide respectively.

He started focusing more on behind the scenes activities in the early 1990s, where he worked as one of the bookers for CMLL and served as the head of the wrestlers' union for many years.

In a 1991 interview, he recalled how he did not have time to play with other boys, as he was watching over all the Alvarado kids while both his father and mother had to work to make ends meet.

[14] In 2013 his daughter made her in-ring debut under the name "Aramís", wearing a modified version of the Brazos mask.

[15] Alvarado was rushed to a Mexico City hospital in the early hours of April 28, 2017, due to respiratory problems.
