Kane and Undertaker aren't related in real life.
in wwe they say that his father(and kane's) is paul bearer
No because Kane or Glen Jacobs and Undertaker or Mark Calaway are not even brothers that was just a storyline.
Because undertakers real brothers name was Kane
They are not related! Kane real name is Glenn Jacobs Undertakers real name is Mark Calaway
