Christian didn't put his hands back on the World Heavyweight Championship against Randy Orton at Over The Limit. By doing so, the WWE used an Old School tactic to put the World Title on a transitional Champion for a few days until their designated Champion got the Gold.
If Christian's case is different from all those in the past, he is still a transitional Champion, so he will get his own slide.
Transitional champions are used to pass the Belt from a babyface to another babyface without getting them to battle each other. When it was required, for the various reasons I will explain in the following slideshow, a heel wrestler was scheduled to beat the reigning World Champion to then lose the Title just few days later against the one wanted by WWE.
So, with no more introduction, let's go back in time to explore the history of the transitional World Champions in WWE.
