Reso debuted in Total Nonstop Action Wrestling at Genesis 2005 pay-per-view under his original ring name, Christian Cage. After teasing an alliance with longtime friend Scott D'Amore and Team Canada, he delivered an Unprettier to D'Amore and helped Team 3D drive Jeff Jarrett through a table.


Christian Cage after winning the NWA World Heavyweight Championship at Against All Odds 2006Cage made his iMPACT! debut on November 19, 2005, engaging in a verbal sparring bout and then brawling with "The Alpha Male" Monty Brown. Cage's in-ring debut for TNA was a win against Team Canada's enforcer Bobby Roode. He defeated Brown at Turning Point to become the number one contender to the NWA World Heavyweight Championship. At Final Resolution 2006, Cage and the returning Sting defeated Monty Brown and Jeff Jarrett.

On February 12, 2006 at Against All Odds 2006, Cage defeated Jarrett to win his first World title, the NWA World Heavyweight Championship.

On April 2, Cage entered into a feud with Abyss after a series of kayfabe videos showed Abyss and his manager James Mitchell stalking Cage's wife and entering his house. They feuded until Lockdown 2006 at which Cage successfully retained his title, but Abyss attacked him after the match and took the title belt. They continued against each other until Sacrifice 2006 where Christian regained his belt in a Full Metal Mayhem match.

Cage defended the NWA World Heavyweight Championship against Abyss, Ron "The Truth" Killings, Jeff Jarrett, and Sting in a King of the Mountain match at Slammiversary 2006. The match was declared unofficial due to the intervening of Larry Zbyszko and referee Earl Hebner at the end of the match when Zbyszko and Hebner snatched the belt and helped Jarrett win. As a result of the finish, the belt was stripped away and declared vacant until Jim Cornette held a "company meeting" on the June 29 iMPACT!, where Cornette awarded the belt back to Jarrett on the condition that he defend it against the winner of a Fatal four way match at Victory Road 2006 involving Christian Cage, Samoa Joe, Scott Steiner, and Sting.

At Hard Justice 2006, Cage watched the Sting vs. Jeff Jarrett match from ringside, supposedly backing his friend Sting. However, at the end of the match, he hit Sting with a guitar, thus turning heel.

Immediately following his actions, Cage would be questioned by Rhino. This would eventually lead to a confrontation between the two, as Cage claimed anger and betrayal at Rhino's questioning of his motives and loyalties, and then gave him the con-chair-to. Cage defeated Rhino at No Surrender 2006 after an Unprettier onto a steel chair. At Bound for Glory 2006, Cage earned another victory over Rhino in an 8 Mile Street Fight.

On the TNA iMPACT! prime time debut, Cage faced off against Rhino in the first-ever Barbed Wire Six Sides of Steel match (a conventional Six Sides of Steel match, only with barbed wire bordering the top of the cage). Christian Cage won when Rhino gored Cage with so much momentum, it sent Cage through the side of the cage and onto the floor. Cage then went on to defeat A.J. Styles at Genesis 2006. The next week on iMPACT!, Christian was reunited with his old 'Problem Solver' from WWE, Tomko, who made his debut in TNA attacking Sting during Cage and Sting's match.

At Final Resolution 2007, Cage captured his second NWA World Heavyweight Championship by defeating Abyss (c) and Sting in a Three Way Elimination Match.

On the February 8 edition of TNA iMPACT!, Scott Steiner attacked Kurt Angle, Samoa Joe and Rhino after a match between Angle and Joe against Cage and Styles, revealing himself as Cage's "special consultant" for his NWA World Heavyweight Championship title defense against Kurt Angle at Against All Odds, the same PPV where he originally won the title a year ago. At the aforementioned PPV, Cage defeated Angle after interference from Tomko and Scott Steiner and the assistance of a lead pipe to retain the NWA World Heavyweight Title.

On the March 6 edition of TNA iMPACT!, Christian Cage had told Kurt Angle and Samoa Joe that with Tomko and Steiner, he heads a "family" which is known as the Christian Coalition, which would prevent anyone from defeating him. Christian Cage, Scott Steiner and Tomko decided to help Abyss, as they beat Sting up.

At Destination X, despite the Coalition's absence from his side (Tomko went to Japan while Steiner fully focused on facing Angle), Cage pinned Samoa Joe by reversing his patented Coquina Clutch into a pin, using the ropes for leverage. Cage became only the third man in TNA history to defeat Joe by pinfall (the others being Angle and Tomko). Prior to the match, he had an exchange with Japanese wrestling legend The Great Muta.

Si mie imi place foarte mult Christian Cage

christian cage e in top 3 din cei mai buni din TNA

se pare ca a fost foarte inspirat cand a plecat din WWE pentru TNA , aici este main eventer iar acolo nu era.

I love Christian . Imi place de el de cand era in echipa cu Edge dar de cand a venit in TNA am inceput sa nu-l mai admir asa de mult
