For the first time in 22 years, the Undertaker was defeated at a Wrestlemania match and that too at the hands of Brock Lesnar, his nemesis. They had a very public showdown at UFC 121 wherein they got into a confrontation. To the dismay of millions of avid WWE fans, Brock Lesnar pinned The Undertaker at Wrestlemania 30, becoming the first wrestler ever to have defeated the Deadman at Wrestlemania.
