#4 Randy Orton (six wins and 10 losses at WrestleMania)
Randy Orton has competed on 16 occasions at WrestleMania. The Viper is hands down one of the greatest villains to ever grace the squared circle. Orton's first WrestleMania match ended with him hitting an RKO on WWE legend Mick Foley and picking up his first win at the event. He suffered his first WrestleMania loss a year later when he fell prey to The Undertaker in 2005.
Orton lost a World title Triple Threat match to Rey Mysterio in 2006, plus a Money In The Bank Ladder match in 2007. He failed to win the WWE title from Triple H at WrestleMania 25 in 2009. The next loss came in 2012 when Orton was put down by Kane in singles action.
The main event of WrestleMania 30 saw Daniel Bryan defeating Orton and Batista to become the new WWE World Heavyweight Champion. Orton lost to WWE greats AJ Styles and Edge at WrestleMania 35 and 36 respectively. He is scheduled to face The Fiend at this year's event in the culmination of a months-long rivalry.
