#3 Braun Strowman
What more is there to say about this monster? He reinvented himself the past two years, and while he hasn't been as dominant in championship or high-profile bouts, he gets to start 2018 out in one of the main events of the Royal Rumble fighting for the Universal Championship against Brock Lesnar (c.) and Kane.
Braun Strowman has yet to become Universal champion, but I have a hunch that by Summerslam 2018, he will win Raw's top prize. Strowman is simply too powerful to stop, and even if he doesn't capture the title at the Royal Rumble, 2018 will be a magical year for the Monster Among Men.
Strowman is one of those once in a lifetime wrestlers and performers that truly allows you to escape the reality and its boundaries over professional wrestling. His matches and promos allow you to suspend your disbelief and really immerse yourself in the WWE product. He has all the tools to make a WWE megastar, and 2018 will be the year that WWE pulls the trigger on the behemoth.
