After that, Sting started a feud with the TNA World Champion Kurt Angle. First, Sting defeated A.J. Styles, Christian Cage, and Samoa Joe in a four-way match to become the co-holder of the TNA World Tag Team Championship with Angle, but lost it 30 days later against Adam "Pacman" Jones and Ron Killings at No Surrender. Sting would face Angle for the World title at Bound for Glory, where Sting won his first TNA World Heavyweight Championship. However, he would lose the title back to Angle two days later on "Impact!" after Kevin Nash interfered on Angle's behalf. Sting would face Angle and Nash at Genesis, with the debutant Booker T as his mystery partner. In the match, whoever scored the pinfall would win the TNA World Championship, which Angle won after pinning Sting to retain the TNA World Heavyweight Championship. This would be the final TNA appearance of Sting in 2007 as he would take some time off to be with his family.
