#16 The Undertaker refuses to stay dead. Or retired.
When The Undertaker was retired at Wrestlemania XXXIII by Roman Reigns, that was it for his career and he would never return.
Until he did.

At RAW's 25th anniversary, fans were shocked to see The Undertaker come out and deliver a promo. While his words were cryptic and mysterious, just as most The Undertaker speeches go, sharp eared fans noticed that he seemed to be hinting at an in ring return.
Their hopes were answered when The Undertaker returned to compete at the Super ShowDown. This led to more appearances, and now fans might see The Undertaker on SmackDown or RAW, which is an unsettling thought for those who would antagonize the Dead Man.
It seems that no matter how many times the The Undertaker dies, he always manages to come back. Here's hoping for many more deaths and rebirths for the one and only Phenom, The Undertaker.
