Triple H came over to the raw brand to reunite with Shawn Michaels as DX in July of 2002. On the night that they were to reunite, he turned on Shawn and pedigree'd him and ripped off the DX shirt. They feuded until SummerSlam where HBK came out of retirement and beat Triple H in an "unsanctioned" match. Triple H put Shawn out for a bit by hitting him in the spine with a sledgehammer following the match.
Triple H then went on to feud with the, then, IC champion Kane. Triple H was the reigning World Champion. We got the Katie Vick angle, as well as Triple H unifying the IC Title with the World Title.
It was unified with the World Title and inactive until May of 2003. Stone Cold brought it back during his Co-General Manager time. Christian ended up winning a battle royal only for former Intercontinental Champions to become the champion.
