#4 Braun Strowman will become Kane
Kane was the original monster of the WWE for over a decade before other monstrous characters showed up. However, Braun Strowman has come the closest to replacing Kane as The Monster Among Men, and the most threatening character in the WWE.
The problem with the Kane character was that he wasn't too good on the mic, and worked storylines which did not do much to take him further in his career.
Kane won a few championships in the WWE, however, he was never a repeat champion when it came to the bigger prizes, and most of his title runs were also ordinary.
Similarly, Strowman has struggled to win any top prize in the WWE, and his only championship win was more of a humorous act than anything else. This has dented the big man's image.
If Strowman goes on to lose against Brock Lesnar at the Royal Rumble, then expect him to fall down the pecking order.
