Nope. Chuck Testa.
The NWO was more than a faction - more than just a couple guys raising hell and spray painting shit on unconscious opponents. The concept worked because it was based in reality; big names came over secretly from another company (WWF), took over the show and allowed their faction to remain "separate" from the host show (WCW). Ok, so maybe that part wasn't necessarily "reality". But Nash, Hall and Hogan really did call the shots. The NWO really was the Kliq of the WCW. Not only did the fans know it, but management knew it and stayed the hell out of their way.
By the time the NWO made its way to the WWF it was a shade of its former self. Watered down. Turned from a shoot-style, industry shaking faction of dominance into a gimmick-fest cycling in and out anybody with a pulse to draw ratings and interest. Not that it didn't have its moments, but anybody with half a brain knew the difference between NWO in the WCW, and NWO in the WWF. Under the Bischoff regime, Hogan and Nash were in control. Under Vince McMahon, Vince McMahon was in control.
Anyways...back to something semi-related to the point...Who does WWE have, right now, that could be somewhat believable in an NWO-esk role? Maybe if they brought in a few big names from TNA without letting the information leak (not likely), and allowed them completely kayfabe control of the company. We all know a) Vince isn't interested in bringing TNA names in, b) if he did there's no way he'd acknowledge their time in TNA to the extent necessary to pull off the angle, and c) TNA isn't a big enough organization to legitimize the angle.
So maybe they bypass bringing in new talents for a new NWO. Maybe they could simply pull it off with the current roster. But who? Who are the fans going to believe is capable of leading the WWE under extreme force? The closest they ever came in recent years was Wade Barrett's Nexus faction. They weren't taking over the WWE using backstage politics, but by brute force alone - the NWO is infamous for the former. So who...?
Brock Lesnar? What stroke could he possibly have? He's a big, brutal, imposing guy...that's about it. Maybe if Heyman came in and joined forces with John Laurinaitis, but why? I suppose if we HAD to put together this team, I'd do it as follows:
Triple H returns after his "final match" to take over the WWE as General Manager, COO, or whatever they want to call him. In the process he does what he was going to do months ago, and gets rid of Laurinaitis as GM - but since he's so intricately involved with as EVP of Talent Relations they can't "fire" him completely. Laurinaitis is seen backstage a few weeks later talking to Brock Lesnar. At some point, likely on a big PPV, Lesnar shows back up with Paul Heyman in tow, and they take out whoever is in the main event picture. The next night on Raw they come to the ring and say they're taking over - that Lesnar is the next in the line for the WWE title, and that Heyman is the new GM of Raw. Triple H comes down for the obvious confrontation, but Heyman reveals that a man with more hiring power than Triple H signed him to a very lucrative, powerful contract that can't be unwritten without strict legal ramifications. Enter Laurinaitis. Lesnar takes out Triple H. The craziness begins.
Triple H and John Cena try to strike back, allowing a window for more members of the nWo to join the fray. Miz is a good choice, and would be a decent mouth piece that isn't taken as seriously. Alberto del Rio could do some damage, but I don't see him on a team with Brock Lesnar. I don't know...this whole thing is stupid, but I'm trying to come up with viable solutions for a terrible idea that's never gonna happen. Ultimately, Lesnar, Miz, and a heel John Cena would be the best possible team to reenact the nWo, with Heyman as their mouthpiece and Laurinaitis as their backstage connection. It COULD work, but they'd never have the balls (nor the need) to go through with it.
