#4. Kane reappears for a one-off appearance with The Undertaker at WrestleMania
Kane should appear at this year's WrestleMania, possibly alongside The Undertaker. Kane is being inducted into the Hall of Fame as a part of this year's class. There's no doubt that Kane has forged a legacy worth commemorating.
The Big Red Machine is truly one of the greatest characters of all time, and that's one of the things WrestleMania encapsulates so well. The larger-than-life characters are what makes wrestling so unique. Why not celebrate that with two of the best making a cameo during the showcase of the immortals?
It almost feels like it's certain that The Undertaker will make an appearance at WrestleMania somehow. Now that he's retired, it's not as certain as to how he will be involved in the show.
It's a safe bet he will be brought back as a special attraction for a moment to make fans happy. We can combine these two things by reuniting the Brothers of Destruction. It's a great way to send off Kane as one of the best performers in the industry's history.
