Career
Anderson was trained by All-Star Championship Wrestling owners Eric Hammers and Mike Krause. He was invited to appear on WWE Jakked, WWE Velocity and WWE Sunday Night Heat in a try-out basis as an independent jobber several times until February 2005, when Anderson signed a developmental contract with WWE. Prior to signing with WWE, Anderson also made some appearances on TNA Xplosion.

World Wrestling Entertainment
Upon signing with WWE, Anderson was sent to the Ohio Valley Wrestling (OVW) farm league. After six months he was called up to work on Velocity. Before his first SmackDown! match, a victory over Funaki, he showed himself to be a cocky and arrogant wrestler with not only his mannerisms but by taking a microphone and performing his own ring announcement. He referred to himself as "Mr. Anderson" for this match. He has since changed his name to "Mr. Kennedy".

2005
Kennedy made his SmackDown! debut on August 25, 2005, once again defeating Funaki. He introduced himself before the match, which he would do week after week. While working on Velocity and SmackDown! he was also still working in OVW.

Kennedy made his pay-per-view debut at SmackDown!'s 2005 No Mercy, defeating Hardcore Holly, injuring Holly's ribs during the match.

On the November 11, 2005 edition of SmackDown!, Kennedy faced Eddie Guerrero for a spot on SmackDown's Survivor Series team. He lost the match when Guerrero tossed him a steel chair and played possum, a move which Guerrero had made famous. The groggy referee turned around and saw Guerrero on the ground with Kennedy holding the chair, and consequently disqualified Kennedy, awarding the place on Team SmackDown! to Guerrero. This was Kennedy's first loss. In retaliation, Kennedy struck Guerrero over the head with the chair after the match. This ended up being Guerrero's final televised match, as he died on Sunday, November 13, 2005 in his hotel room in Minneapolis, Minnesota, where a SuperShow taping of both RAW and SmackDown! was to be held. In interviews about the incident, Kennedy has stated that he considers this an "unfortunate honor".

In December 2005 Kennedy participated in WWE's "overseas" tour. On the second day in Italy Kennedy suffered a serious latissimus dorsi tear. He attempted to work through the injury, but was said to have been hurting so bad that he couldn’t even put his hand in his pocket to get his wallet at a restaurant. Seeing a doctor he was informed that he'd suffered a complete tear, compared to Batista’s partial tear from earlier in the year, and that he would not be able to work through it, even with a somewhat lighter schedule, instead he would need surgery. The December 6, 2005 surgery was a success but Kennedy was still forced out of the ring for nearly six months while he rehabbed the injury.

2006
Though he couldn't wrestle, Kennedy still returned to SmackDown! on January 6, 2006. This time, it was as a color commentator for a Cruiserweight Title match. He continued to make appearances on SmackDown! and Velocity throughout January and February, making his ring announcement and commentating specific matches. He even made an appearance on the January 11, 2006 edition of Byte This! with Todd Grisham to maintain visibility.

At the OVW tapings on May 10, 2006, Kennedy returned to in-ring action facing the OVW Heavyweight Champion, CM Punk in a title match that Kennedy was unable to win. Kennedy would make his return to SmackDown! on June 9, 2006 with a victory over Scotty 2 Hotty after using a Kenton Bomb.

Since returning he has continued his ongoing "mini-feud" with SmackDown! ring announcer, Tony Chimel, which began prior to his injury in 2005. The feud is based on Kennedy believing Chimel's announcing is not well enough or done with the right amount of respect and thus Kennedy must either perform his own introductions or force Chimel to announce him again.

Kennedy lost by pinfall, ending his streak on SmackDown! of never being defeated by pin or submission, on the July 14, 2006 edition of SmackDown!, when he was rolled up by Matt Hardy.

On the July 21, 2006 edition of SmackDown!, Batista put out an open challenge to replace his opponent Mark Henry, who had been injured, at The Great American Bash on July 23, 2006 for the Number 1 Contender spot. Kennedy accepted the challenge and went on to win the match by disqualification. However, he suffered a severe injury during the match after being thrown headfirst into the steel steps, resulting in an exposed cranium laceration which required 20 stitches to close. He then entered into a short feud with Batista, defeating him by count out in their second match, but losing via pinfall in the third.

Kennedy would also help Shane and Vince McMahon in their feud with DX, appearing at both SummerSlam and the August 28, 2006 edition of RAW along with others from the SmackDown! and RAW rosters to attack DX.

On the September 1, 2006 edition of SmackDown!, Kennedy defeated Finlay and Bobby Lashley in a Triple Threat Match to win the WWE United States Championship, his first title reign in WWE.

On September 8, 2006 edition of SmackDown!, Kennedy announced that he wanted to move over to RAW, as SmackDown didn't interest him anymore because he had already defeated every top star on the roster. This led to SmackDown! General Manager Theodore Long making a match between Kennedy and The Undertaker (who Kennedy had never faced) to be held at WWE No Mercy 2006, which Kennedy would go on to win by disqualification.

On the October 13, 2006 edition of SmackDown!, Kennedy, now with a win over The Undertaker in the books, again stated his desire to move to RAW, and again Long put him against an opponent who he had never faced - this time Chris Benoit - with Kennedy's title on the line. Long said that, if Kennedy were to defeat Benoit, he would be given his release and be allowed to go to RAW. Kennedy lost the United States Championship to Benoit after a distraction from The Undertaker, who was standing in the entrance. Kennedy tapped out to the Crippler Crossface, marking his first submission loss.

Late in 2006, Kennedy and Montel Vontavious Porter took on the Brothers of Destruction (Kane and Undertaker) in various combinations. Kennedy was able to beat Kane with help from MVP in a No DQ Match. The next week, both Kennedy and MVP lost to the Brothers Of Destruction three times. They first got counted out, and Theodore Long restarted the match with no countouts. Then they disqualified themselves with a low blow by Kennedy, and Long restarted the match again with no countouts and no disqualifications.

Kennedy and MVP would continue to feud with the brothers, with MVP feuding with Kane while Kennedy challenged The Undertaker to a match at Survivor Series, which was later announced as a First Blood match. Kennedy won that match after MVP turned on him and aimed for his head with a steel chair, but missed and hit The Undertaker instead, busting him open. After the match, the Undertaker viciously attacked Kennedy, forcing him to bleed.

Even after being thrown of the top of the "Armageddon" symbol above the ramp, Undertaker was finally able to beat Kennedy at Armageddon 2006 in a Last Ride Match.

2007 - present
Mr. Kennedy taunting Hardcore Holly at a Raw house show.After a brief hiatus, Kennedy returned to SmackDown! on January 5 and defeated Chris Benoit in a "Beat the Clock" match, with the overall prize being a shot at Batista's World Heavyweight Championship at the upcoming Royal Rumble. After he prevented The Undertaker from beating his time, Kennedy's time of 5:07 ended up being the fastest.[32] At the Royal Rumble, he had Batista pinned for a three count while the referee was out of position but ended up losing the match anyway, as well as a subsequent rematch. From there, Kennedy began a short feud with ECW World Champion Bobby Lashley, leading to a match at No Way Out which Kennedy won by disqualification, preventing him from becoming champion.[35] Kennedy challenged Lashley unsuccessfully on ECW and SmackDown! as well.
Kennedy earned a spot in the 2007 Money in the Bank ladder match by defeating Sabu in an Extreme Rules match. At WrestleMania 23, Kennedy won the Money in the Bank ladder match, giving him the right to challenge any World Champion in WWE at any date up until WrestleMania XXIV.Kennedy announced on the April 30 edition of Raw that he would be cashing in his Money in the Bank championship opportunity at WrestleMania XXIV. However, on the May 7 edition of Raw, Mr. Kennedy lost his Money in the Bank opportunity to Edge, losing mere moments after a blow to the head from a monitor before the match began. Mr. Kennedy never got the chance to win the briefcase back, however, as Edge cashed the briefcase in to win the World Heavyweight Championship from the Undertaker on SmackDown! the next day. Because of the injury Kennedy sustained at the hands of Edge, it was believed that his right triceps muscle tore off of the bone and he would be out for a minimum of five to seven months.The injury, however, was not as serious as once predicted, as the triceps tendon did not tear off the bone but was, in fact, a massive hematoma.
On the June 11 edition of Raw, Mr. Kennedy was drafted from SmackDown! to Raw as part of the WWE Draft. On the July 30 edition of Raw, Kennedy not only defeated Bobby Lashley, but seemingly injured him in the process. On August 20, Carlito hosted his interview segment, Carlito's Cabana, when Carlito challenged his special guest, Umaga for his Intercontinental Championship at SummerSlam. Mr. Kennedy, however, came out and said he deserved a match with Umaga because he did what Umaga could not do, defeat Bobby Lashley and put him out of action. William Regal, Raw's General Manager, came out and booked Kennedy vs. Carlito for later in the night, in which the winner would face Umaga at SummerSlam. After the match ended in a draw, Regal ordered that there would be a Triple Threat match at SummerSlam between the three men for the Intercontinental Championship; at the event, Umaga retained the title. On the September 10 edition of Raw, Mr. McMahon revealed that Kennedy had been kayfabe suspended for impersonating a McMahon. In actuality, Mr. Kennedy was one of the eleven Superstars implicated in the steroid scandal and therefore suspended for thirty days in accordance with WWE's Wellness Policy.
Kennedy making his ring entrance at a Raw house show in 2007Kennedy returned on the October 1 edition of Raw after his suspension facing John Cena in the main event. Although Kennedy did not win, Cena was injured during the match as he suffered a complete tear of his right pectoral tendon. At No Mercy, Kennedy took part in a bonus six man tag team match alongside the World Tag Team Champions Lance Cade and Trevor Murdoch defeating Intercontinental Champion Jeff Hardy and Paul London and Brian Kendrick. For the next several weeks, Kennedy would be involved in a feud with Jeff Hardy that consisted of the two facing off in a singles match and numerous tag team matches, most of which Hardy won. At Cyber Sunday, Kennedy and Hardy were two of the eligible wrestlers that could earn a WWE Championship match for that evening pending on the fan's votes. Neither man won the opportunity as Shawn Michaels won the vote and earned a shot at the title. Although neither won the title shot, Kennedy defeated Hardy in a bonus match made by William Regal.
Kennedy entered a program with Shawn Michaels on the night after Survivor Series. Kennedy claimed that it was time for Michaels to move on and let the younger, talented superstars climb the ladder to success. At Armageddon, Michaels defeated Kennedy, after he was able to hit Kennedy with Sweet Chin Music. On the December 31 edition of Raw, Kennedy and Michaels had a rematch where Kennedy pinned Michaels following his new finishing move, the "Mic Check".In subsequent rematches, the duo traded wins over each other. At the Royal Rumble, Kennedy eliminated Michaels from the Royal Rumble match, thus ending the rivalry between the two.
After several months of minor feuds and short storylines, Kennedy was not seen for weeks after WrestleMania XXIV, because he was filming a role for the new movie Behind Enemy Lines 3. Kennedy returned to Raw on April 28, as he confronted and brawled with General Manager and newly crowned King of the Ring William Regal, turning face in the process. On a following edition of Raw, Kennedy defeated General Manager Regal in a "Loser Gets Fired Match" completing the face turn and opening up the General Manager spot on the Raw brand.
On June 23, 2008, Kennedy was drafted from the Raw brand to the SmackDown brand, as a part of the 2008 WWE Draft. On August 4, he dislocated his shoulder in a match against Shelton Benjamin.
