He is a member of the Brazo Family and is a third-generation luchador. His father is Robin Hood. Seemingly started in IWRG. He debuted as a technico in CMLL in 2010 in opening matches, and never progressed past this role after several years.
Before picking up the name Robin, he used Brazo Cibernetico and Brazo de Plata Jr. The name of Robin (and his legit first name) comes from his dad's ring name which was Robin Hood. He chose not to use the name of Robin Hood because his dad ran into rights issues by using the name. He said people often think his name comes from Batman and Robin and often joke with him about it.
Robin was the only Alvarado who wasn't fired from CMLL over the attacking Último Guerrero's car incident in May 2017, probably because he was just too low-card for it to matter. Kept plugging away, rarely ever making it to Friday cards, before being the sacrificial mask in Sin Salida, 2026.
In his spare time, he and his wife run a side business where they make ceramic lucha libre toys. It has been hinted at that his wife is related to Ephesto. He is known for his delicious secret gordita recipe. He enjoys Spiderman, sushi and a Mexican soccer team called Club America.
