Justice Rear Naked Choke (ジャスティス裸閉め Jasutisu Hadakajime) is Top's finishing hold technique.
Toppo puts his opponent in a very powerful bear hug. This hold was powerful enough to cause Goku to revert into his base form from Super Saiyan. Vermoud also mentioned Toppo wouldn't stop until all of Goku's bones were broken.
During the Tournament of Power, Toppo used this against Vegeta, who was distracted by Goku and Kefla's battle. However, Vegeta was able to break free after a bit of struggling by elbowing Toppo in the stomach.
