10. X-Pac (Syxx-Pac In WCW)
WWE.comWhen Sean Waltman started in WWE as the 1-2-3 Kid he was just about to turn 21 years old. There are very few wrestlers in the history of the business that make it into WWE at such a young age. It's a testament to how good he was. He went from being a rookie to a respectable performer before leaving for WCW in 1996 a few months after his buddies Scott Hall and Kevin Nash left WWE for WCW. His WCW career lasted less than two years. While WCW did a lot of things right with the birth of the New World Order, they were not the best at developing talents. He quickly became just an average guy lost in the midcard that would battle for various titles, but never really stood out while there. He had developed drug and alcohol issues while also dealing with a severe neck injury. He was fired while he was injured. https://www.youtube.com/watch?v=XepdzlxpqcY The best moment of his career was when he returned to WWE in 1998 on the Raw after WrestleMania 14. They gave him the microphone and he ripped into Hulk Hogan and Eric Bischoff big time. You didn't hear that sort of thing in a WWE ring, but he had no problem doing it. It was probably the most memorable moment of his career. He spent a few years in WWE mostly as part of Degeneration X, bounced around a bit and eventually signed a Legends Deal with WWE in 2013. Maybe he'll be in the Hall of Fame one day on his own, but perhaps it will be with DX as a group. Either way, he's in a good spot since one of his best friends Triple H is one of the biggest names in WWE today.
