On the December 30 episode of "Raw", Lesnar returned with Heyman to challenge the winner of the upcoming WWE World Heavyweight Championship match between Randy Orton and John Cena at the Royal Rumble. Lesnar then dared any wrestler who disapproved of that notion to challenge him, which was answered by Mark Henry. The ensuing brawl ended with Lesnar delivering an "F-5" to Henry. The following week on "Raw", Henry challenged Lesnar again, only to have Lesnar dislocate his elbow with the Kimura lock in storyline, which led Big Show to come out afterwards to confront Lesnar, thus starting a feud which was settled at the Royal Rumble on January 26, 2014, where Lesnar defeated Big Show after attacking him with a steel chair before the match began. On the February 24 episode of "Raw", Heyman stated that Lesnar had requested a match for the WWE World Heavyweight Championship at WrestleMania XXX, but received an open contract to face anyone else of his choosing instead. The Undertaker then returned and attacked Lesnar with a chokeslam through a table, setting up their match at WrestleMania XXX. At WrestleMania on April 6, Lesnar defeated Undertaker after executing three "F-5"s, ending his undefeated WrestleMania streak at 21, a feat that was described by "Sports Illustrated" as being "the most shocking result since the Montreal Screwjob".
