#1. WWE signs The Undertaker to a lifetime WWE contract
Rumor: The Undertaker retired from WWE (after confirming his appearance at Starrcast II)

There has not been a single more iconic WWE Superstar than The Undertaker. From making his WWE debut at Survivor Series 1990 to his most recent appearance at SmackDown Live, The Undertaker has been a cornerstone in WWE's triumph for over 25 years. So, when The Phenom teased his retirement after Wrestlemania 33, fans could not help but shed a tear.
However, The Deadman was not done. He returned at the WrestleMania next year to defeat John Cena in a squash match. He made more appearances until his loss to DX at Crown Jewel. Since then, we've heard little about The Undertaker.
A rumor then started to do the rounds that The Undertaker's contract was up with WWE and that he would officially retire. Taker's confirmation to appear at Starrcast II, a non-WWE show, added fuel to the fire.
However, WWE responded to this buzz by simply signing The Deadman with a lifetime contract. Since then, The Undertaker competed against Goldberg at WWE Super ShowDown and teamed with Roman Reigns to defeat Shane McMahon and Drew McIntyre at Extreme Rules.
