Scott Hall returned to the World Wrestling Federation and reunited with Kevin Nash and Hulk Hogan to repackage the nWo in February 2002. He started a feud with Stone Cold Steve Austin and they fought each other in a match at WrestleMania X8 which Austin won. On the March 25 edition of Raw, Hall was drafted to the Raw brand as a result of the Brand Extension, where he feuded with Bradshaw, culminating in a match at Backlash which Hall won. Hall then continued his feud with Austin before being released from his WWF contract due to personal issues stemming from a child-custody dispute with his wife and an airline altercation.
All of this occurred at the same time WWE was rebranding themselves from the former WWF... but I think you already knew that... right??
