At WrestleMania XIV, Shawn Michaels wrestled his last match for WWF/E for more than four years, losing the WWF Championship to Steve Austin. HBKs departure seemingly spelled the end for D-Generation X with only Triple H and Chyna left in the renegade faction. But Helmsley had an ace up his sleeve in the form of the former 1-2-3 Kid. It seems funny on a list like this to have someone like X-Pac ranked this high, but consider this: The re-debut of Sean Waltman helped launch D-Generation X 2.0, a faction that helped bolster WWFs ranks during the Monday Night Wars. At the same time, X-Pac was the first notable wrestler to cross the line from WCW to WWF. Until that point, every jump had been in the opposite direction.While not expressly referred to as the 1-2-3 Kid, Waltman was not treated as an entirely new person. Jim Ross commented, Well look whos back, when he walked out. X-Pac though came in as a different character than when he left WWF two years earlier, essentially re-debuting.
