Just to give you some context, in mid 1996, Scott Hall (Razor Ramon) and Kevin Nash (Diesel), two of the WWFs biggest stars joined the WCW and started an almost invasion angle, where they would both come to the WCW and take over. Eventually it was revealed that Hulk Hogan was their partner as well and the three of them would basically terrorize WCW on a weekly basis for about a year. One of their first matches as a group was at War games, which is kind of like hell in a cell, but it's 4 on 4 and you can only win by one member submitting. The WCW team was Rick Flair, Arn Anderson, Lex Luger and Sting vs the nWo team, consisting of Hogan, Hall, Nash and a mysterious 4th member. In the weeks leading up, the nWo used a Sting impersonator in order to make team WCW turn their back on Sting, which resulted in a 3 vs 4 match where Sting didn't show up, but the imposter sting did, which led to the real sting showing up (still not the crow look) and knocking out the entire nWo, before asking how's this for proof, then leaving. The nWo team won in the end and on the next night, Sting basically said since WCW didn't trust him, he's a free agent, but for every fan that stuck by him, he will stick by you.
So over the course of the next year, the nWo would grow and constantly attack wrestlers back stage with bats, interfere with matches and have wrestlers stripped of titles and awarded to them. Occasionally Sting would show up in the rafters with his new Crow look, but would never take a side in the WCW/nWo conflict. At Uncensored, there was a 4 on 4 on 4 match that involved the nWo (Hogan, Hall, Nash, Savage), team WCW (Luger, Giant, Scott Steiner, Rick Steiner) and team Piper (Piper, Benoit, Jeff Jarrett, McMichaels), that of course the nWo won. After that Sting finally picked a side and then began terrorizing the nWo for the next year in a similar manner as well as some Undertaker like mind games.
