"The Big O" Bob Orton Sr. began his career wrestling for various territories in North America before capturing the NWA tag titles with Eddie Graham in 1966. His use of the piledriver caused fans to fear him and Orton made a living traveling to the various regional promotions, capturing titles wherever he stopped. However, Bob Sr.'s biggest contribution to the wrestling business may be the offspring he produced. Bob Orton Jr. rose to national fame after being trained by Hiro Matsuda and tagging with his father in Florida. One of the toughest and most technical men in wrestling, he had a feud with Ric Flair in the NWA territories before being swept up by the WWF during their national expansion in the 1980s. He became a central figured in the biggest angle of the time, playing the role of Roddy Piper's bodyguard during Piper's legendary feud with Hulk Hogan. Orton was in the corner of Piper and Paul Orndorff when they challenged Hogan and Mr. T in the main event of the first Wrestlemania. Orton again took center stage in a main storyline when he ditched Piper to join up with Adrian Adonis. Orton betrayed his longtime friend Piper and donned a pink cowboy hat in favor of the flamboyant Adonis. This would lead to a violent feud with Piper that Orton would subsequently lose. As good as Bob Orton Jr. and Sr. were, Randy Orton may have topped them all. Winning his first world title at only 24 years old, Orton became the youngest heavyweight champion in WWE's history and would go on to capture the title 11 more times. His rise to stardom began with his inclusion in the Evolution stable alongside Triple H, Ric Flair, and Batista. Orton rose up the card and would eventually feud with his former stablemates over the world title. More recently, Randy Orton has become a perennial rival of John Cena's and seems to have many more world title reigns ahead of him.
