On August 4, 2006, WWE announced that Hardy had re-signed with the company.
In the following weeks, vignettes aired hyping his return on the August 21 episode of Raw.
On the day of his return, Hardy confronted then WWE Champion Edge, before an altercation between the two that ended when Lita pulled Edge out of the ring, preventing Hardy from delivering a Swanton Bomb.
After failing to capture the Intercontinental Championship from Johnny Nitro over the next few weeks, including at Unforgiven, Hardy finally defeated Nitro to win his second Intercontinental Championship on the October 2 episode of Raw.
On the November 6 episode of Raw, Hardy lost the Intercontinental Championship back to Nitro, after Nitro hit him with the Intercontinental Championship title belt.
One week later, Hardy regained it on the November 13 episode of Raw, with a crucifix pin.
This marked Hardy's third reign as Intercontinental Champion.

On the November 21 episode of ECW, Hardy teamed with his brother, Matt, for the first time in four years to defeat The Full Blooded Italians.
At Survivor Series, they both were a part of Team D-Generation X, which gained the victory over Team Rated-RKO with a clean sweep.
The brothers then received their first opportunity since Hardy's return to win a tag team championship at Armageddon.
They competed in a four-team ladder match for the WWE Tag Team Championship, but they came up short in their attempt.
In the course of the match, however, they inadvertently legitimately injured Joey Mercury's face.

With Hardy still feuding with Johnny Nitro and the other members of MNM into 2007, he was challenged once again by Nitro at New Year's Revolution in a steel cage match for the Intercontinental Championship.
Hardy once again defeated Nitro.
Hardy then teamed with Matt to defeat MNM at both the Royal Rumble and No Way Out pay-per-views.
The next night on the February 19 episode of Raw, Hardy lost the Intercontinental Championship to Umaga.
In April 2007, Hardy competed in the Money in the Bank ladder match at WrestleMania 23.
During the match, Matt threw Edge onto a ladder and encouraged Hardy, who was close to the winning briefcase, to finish Edge off.
Hardy then leaped off the 20-foot-high (6.1 m) ladder, drove Edge through the ladder with a leg drop, injuring both Edge and himself.
The two were unable to continue the match and were removed from ringside on stretchers.

The night after WrestleMania on the April 2 episode of Raw, the Hardys competed in a 10-team battle royal for the World Tag Team Championship.
They won the titles from then WWE Champion John Cena and Shawn Michaels by last eliminating Lance Cade and Trevor Murdoch.
They then began a feud with Cade and Murdoch, with the Hardys retaining the Championship in their first title defense against them at Backlash and again at Judgment Day.
The Hardys then defended their titles against The World's Greatest Tag Team in a Ladder match at One Night Stand.
However, the next night on Raw, the Hardys lost the titles to Cade and Murdoch, competing through injuries sustained in their previous night's ladder match.
The Hardys earned a rematch at Vengeance: Night of Champions but were defeated.
