3. Kane
Kane as a character has lost his relevance lately due to his frequent character changes and bad booking decisions. But, he is one of the stars from the bygone era who is eager to work storylines with younger stars and help them establish themselves.
Kane’s build and his monstrous character has made him just the right adversary for any rookie. Kane was involved in Umaga’s first legitimate feud which established Umaga as a monster heel. Even Khali and Gene Snitsky (the guy who caused Lita’s kayfabe miscarriage) were put over by Kane, though it did not help these stars due to their own limitations.
If you look at “Team Hell No”, it was Kane who played a perfect foil for Daniel Bryan and helped him in getting over. Though Kane has been off air for some time now, fans are anxiously awaiting “The Big Red Monster” to return to the ring and breathe fire again before his last hurrah.
