Justice Rear Naked Choke (ジャスティス裸締め 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. Belmod also mentioned Top wouldn't stop until all of Goku's bones were broken.
During the Tournament of Power, Top 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.
