Wellington Leal "Megaton" Dias[1] (born October 2, 1967) is a Brazilian jiu-jitsu (BJJ) practitioner, and an official black belt representative of the Royler Gracie Jiu-Jitsu Association. Wellington originally trained under Rogerio Camoes and later at the legendary Gracie Humaitá jiu-jitsu school in Rio de Janeiro. Wellington received his black belt at the age of 18. Wellington is currently a fifth degree black belt under Royler Gracie.

Wellington is a multiple Pan-American medalist, European medalist, Worlds medalist, US National medalist, Rickson Gracie International Championship medalist, Rio de Janeiro State Champion and Abu Dhabi veteran, among other accomplishments.[2]

He is the only Brazilian jiu-jitsu competitor to have competed in all 23 World Jiu-Jitsu Championships, realized since (and including) the first edition in 1996.[3]

Wellington Dias resides in Phoenix where he directs the Megaton Brazilian Jiu-Jitsu Academy, the first BJJ academy in Arizona. Megaton has trained in judo and Brazilian jiu-jitsu since 1976. His wife Luciana and daughter Mackenzie Dern are also black belts in the discipline, under his tutelage.[4][5]

Dias is nicknamed "Megaton" because of his judo training and propensity to launch his competitors high into the air, similar to the blast of a nuclear bomb. "Megaton" was named the #1 ranked nickname in MMA by SubFighter.[6]
