This is gonna be a write up of their upcoming match looked at from lots of perspectives:
First off, SUBMISSIONS:
this is a category Kane is very lacking in. He has some bearhugs and nerve holds and chokes, but he is not the submissions master the Undertaker is. Undertaker can pick a leg or arm and bar it. He can do chokes, holds, all that jazz. Kane can't win with a simple chinlock or choke, but Undertaker has 3 holds that can take out opponents, his Hell's Gate (current favorite), his Trinagle Choke, and his Dragon Sleeper.
Yes, I know it's weird, but Koko did indeed turn heel for two shows in 1990. Paul Roma actually started teaming with Hercules as faces. They had a few matches as good guys, then they turned into a hell tag team by picking Slick as thier manager.
