Máscara Dorada

The search results reveal two different wrestlers with the Máscara Dorada name. The original Gran Metalik briefly worked NJPW multiple times between 2010-2016, not recently. The current Máscara Dorada (born 2001) is a younger wrestler who has appeared for NJPW through CMLL partnerships but is primarily signed to CMLL and AEW. Since you asked specifically about the Máscara Dorada "associated with NJPW," I'll write about the original version whose NJPW career is more prominently documented, though that career ended in 2016.

Mexican high-flyer known for a decade in CMLL and time in WWE as Gran Metalik, where he portrayed a técnico known for high-risk aerial lucha libre with frequent ring dives. At one point held the Mexican National Trios Championship, the CMLL World Trios Championship, the CMLL World Super Lightweight Championship, and the CMLL World Welterweight Championship simultaneously.

Returned to NJPW in February 2022 after six years away, defeating TJP in his first match back during Strong Style Evolved. Made his final NJPW appearance in January 2023.
