#3 Kane
Kane is another wrestler, who might choose to retire in 2018.
There is no doubt that he is one of the greatest wrestlers ever in the WWE, but he is 50 years old now and his physique and health are not what it used to be initially.
Over the year, Kane has presented to us the perfect replica of a demon.
With or without his mask, Kane on his day could rip apart an entire locker room and still stand on his feet. His entrance music, his wrestling moves and his special inferno match, gave him a larger than life image.
However, Kane has lost the significance he used to have in late 90's or in early 2000. We hardly get to see the vicious Kane anymore.
He has also made appearances in various movies and TV Shows. He is also a part-time politician and has plans to take that as a full-time commitment once he retires.
Even though it will be heart-wrenching, but 2018 is probably the last year for Kane in the WWE.
