On the June 2 episode of Raw, after Batista left Evolution and WWE, Triple H revealed his "plan B", which turned out to be Rollins attacking Dean Ambrose and Roman Reigns and rejoining The Authority, turning heel once again.
Rollins later explained his actions by stating that The Shield would not be a success without him and Ambrose and Reigns were not his brothers, like they claimed, but business partners to help him move up in WWE.
On the June 17 episode of Main Event, Rollins, acting on behalf of The Authority, entered himself into the traditional Money in the Bank ladder match for a WWE World Heavyweight Championship contract at Money in the Bank, which he won after Kane knocked out Ambrose and held the ladder in place for Rollins to climb.
Rollins defeated Ambrose twince, at Battleground, in July, via forfeit, after their match was called off by Triple H since Ambrose attacked Rollins backstage, and in August, at SummerSlam, in a lumberjack match.
On the August 24 episode of Raw, Rollins defeated Ambrose in a Falls Count Anywhere match and injured him (in the storyline) after executing a Curb Stomp through cinder blocks.
In September, a match between Rollins and Roman Reigns was set up for Night of Champions, but six days before the pay-per-view, Reigns cleanly defeated Rollins in a singles match on Raw.
However, Reigns developed a legitimate incarcerated hernia which required surgery a day or two prior to Night of Champions and, as a result, Rollins was declared the winner via forfeit, but he was then attacked by a returning Ambrose.
On the September 29, episode of Raw, Jamie Noble and Joey Mercury aligned themselves with The Authority and statred acting as bodyguards to Rollins.
At Hell in a Cell, Rollins defeated Ambrose in a Hell in a Cell match after Bray Wyatt interfered and attacked Ambrose.
At Survivor Series, Rollins captained Team Authority in a five-on-five elimination tag team match against Team Cena, in which Rollins was the sole survivor and was eliminated by Dolph Ziggler.
Rollins continued his feud with Cena in December at TLC: Tables, Ladders and Chairs, which led to a tables match, which Cena won.
On January 25, 2015, at Royal Rumble, Rollins competed for the WWE World Heavyweight Championship in a triple threat match against Cena and Brock Lesnar, which Lesnar won.
In February, Rollins started a war-of-words feud with The Daily Show host, Jon Stewart, claiming that he could host the show better than Stewart.
Rollins was attacked by the return Randy Orton following his match at Fastlane, which led to a match at WrestleMania 31, where Rollins was defeated.
Later that night, Rollins cashed in his Money in the Bank contract during Lesnar and Reigns' fifteen minutes match, making it into a triple threat match, which Rollins won by pinning Reigns to win the WWE World Heavyweight Championship for the first time in his career.
Rollins continued his feud with Orton after WrestleMania 31, which led to a steel cage match, with Orton's RKO banned and Kane as the gatekeeper, at Extreme Rules, where Rollins retained his championship by escaping the cage, despite Kane attacking both, after performing an RKO on Orton.
In May, tension rose between Rollins and Kane, after the latter announced Rollins' title defence against Orton and Reigns at Payback, and after Dean Ambrose defeated Rollins on an episode of Raw, he was added to the match, which saw Kane siding with him and Rollins winning the match after performing a Pedigree (Triple H's finishing move) on Orton.
Rollins then retained the championship against Ambrose, on May 31 at Elimination Chamber, after he got himself disqualified for shoving the referee, and, on June 14 at Money in the Bank, in a ladder match.
At Battleground, Rollins retained his championship by disqualification against Lesnar, after The Undertaker attacked Lesnar.
Rollins then re-ignited his feud with John Cena, and defeated him in a Winner Takes All match at SummerSlam on August 23, for both the WWE World Heavyweight Championship and the United States Championship, after Jon Stewart attacked Cena.
With the win, Rollins became the first and only wrestler to hold both championships simultaneously, until he went on to lose the United States Championship back to Cena at Night of Champions on September 20, but was able to retain the WWE World Heavyweight Championship in a clean finish against Sting.
On October 25 at Hell in a Cell, Rollins successfully defended the championship against "Demon" Kane, and as a pre-match stipulation, "Corporate" Kane was fired as Director of Operations.
On November 4, during a match against Kane at a WWE live event in Dublin, Ireland, Rollins tore the ACL, MCL, and medial meniscus in his knee while attempting to execute a sunset flip powerbomb.
The injury required surgery and it was estimated it would take Rollins out of action for approximately six to nine months.
As a result, Rollins was forced to vacate the WWE World Heavyweight Championship the next day, ending his reign at 220 days.
On the December 21 episode of Raw, Rollins (on crutches) made a special appearance to accept his Slammy Award for 2015 Superstar of the Year, and during his acceptance speech, Rollins claimed he would redesign and rebuild himself, and also reclaim the WWE World Heavyweight Championship which he never lost.
