#4 Randy Orton (WrestleMania 25 to WrestleMania 26)
Randy Orton was at the top of his game as WrestleMania 25 approached in early 2009. He had become a vicious and ruthless character, ready to go to great lengths to get what he wanted. Orton won the 2009 Royal Rumble match that year and kicked off a heated feud with the McMahon family. It culminated in a WWE title battle with Triple H in the main event of The Show of Shows.
Triple H destroyed Orton at WrestleMania to retain his belt. The match wasn't anything impressive but at least gave Orton a huge spot on the card. Things weren't the same a year later.
Orton started to embrace his good side as WrestleMania 26 approached closer in 2010. Legacy (Orton, Cody and Ted Dibiase) disbanded and the trio was involved in a Triple Threat match at WrestleMania. The match didn't even last 10 minutes before Orton picked up the victory. The match was placed at the 3rd spot on the card.
