Face turn and various feuds (2009–2010)
After defeating Morgan at Bound for Glory, Angle came out on the following edition of Impact! and put over the younger talent of the company, turning face in the process. Afterward, he was assaulted by the debuting Desmond Wolfe,[108] who defeated him via knockout in a street fight the following week. At Turning Point Angle defeated Wolfe in a rematch. The following month at Final Resolution Angle faced Wolfe in a "Three Degrees of Pain" two out of three falls match. Wolfe managed to gain the first fall by pinning Angle following the Tower of London, but Angle forced him to tap out with the ankle lock to win the second fall. In the final fall, which could only be won by escaping the Six Sides of Steel, Angle managed to escape first and won the match. On the January 4, 2010, live, three hour, Monday night edition of Impact! Angle received a shot at A.J. Styles' World Heavyweight Championship, but was defeated in the main event of the show. Two weeks later at Genesis Angle received one last shot at the World Heavyweight Title, but was once again defeated by Styles, who turned heel with the help of Ric Flair and nailed him with the title belt. As a result, Angle was barred from challenging for the belt as long as Styles is the title holder. Due to the circumstances surrounding the loss, Hulk Hogan gave Angle another shot at Styles and the TNA World Heavyweight Championship on the January 21 edition of Impact!, but this time he lost the match after referee Earl Hebner, who was later revealed to have been paid off by Flair, called for the bell in an incident similar to the Montreal Screwjob. Angle responded to the incident by spitting in Hogan's face, threatening to quit TNA and go back to WWE.[114] Angle apologized to Hogan, after being saved by him from Scott Hall and Syxx-Pac. At Against All Odds Angle took part in the 8 Card Stud Tournament to crown a new number one contender, but was defeated in the first round by Mr. Anderson, after Anderson used Angle's dog tags to bust him open. On the following edition of Impact! Angle promised to make Anderson suffer for disrespecting the U.S. soldiers, but was in the end once again laid out by him, effectively starting a feud between the two.At Destination X Angle defeated Anderson in a rematch. Angle and Anderson were booked in a rubber match inside a steel cage at Lockdown. On the April 5 edition of Impact! Anderson defeated Angle in a ladder match to win possession of the key to the cage door. At Lockdown, Angle defeated Anderson in a steel cage match and afterwards announced that he would now be taking some time off from wrestling.Rankings climb, feud with Immortal (2010–present)
Angle returned on the May 20 edition of Impact! and was ranked number two by the Championship Committee in the inaugural top 10 rankings for a World Heavyweight title shot. Angle, however, decided to take his name out of the running for a title shot and vowed to fight his way through the top 10 and earn his spot at the top of the company. At Slammiversary VIII Angle started his climb back to the top by defeating Kazarian, who was ranked number ten. Angle continued his climb, defeating Desmond Wolfe, who was ranked number nine prior to the match, on the June 24 edition of Impact!, and D'Angelo Dinero, ranked number eight, at Victory Road. Prior to his match with Dinero, Angle announced that should he lose on his way to the top of the rankings, he would retire from professional wrestling On the July 22 edition of Impact! Angle defeated number seven ranked Hernandez and followed that up three weeks later by defeating number six ranked A.J. Styles. On the August 19 edition of Impact! the TNA World Heavyweight Championship was vacated and instead of continuing his climb, Angle was entered into an eight man tournament for the title, defeating X Division Champion Douglas Williams in his first round match. At No Surrender Angle first wrestled Jeff Hardy to a twenty minute time limit draw, after which Eric Bischoff ordered a five minute extra time. After that and a second five minute extra time also ended in draws, it was ruled that, due to a cut, Angle wouldn't be allowed to continue the match, ending the match in a no contest. After wrestling a draw on the September 16 edition of Impact!, it was announced that both Angle and Hardy would advance to the finals at Bound for Glory, where they would compete with Mr. Anderson in a three–way match. At the pay-per-view Angle was defeated by Hardy, when he turned heel and pinned Anderson, after an interference from Hulk Hogan and Eric Bischoff, who then went on to form an alliance named Immortal, with Hardy, Abyss and Jeff Jarrett.
On the following edition of Impact! Angle came out to make his retirement speech, after his failed attempt to win the World Heavyweight Champion, but was interrupted by Jarrett, who announced that he had made a deal with Hogan and Bischoff in order to end Angle's career at Bound for Glory, before attacking him, when he was restrained by TNA's security officers. The following week Angle returned, trying to get his hands on Bischoff and Ric Flair, before being stopped by TNA's security officers.
