Bálor made his return on 9 December episode of NXT where he was confronted by O'Reilly, Pete Dunne, Damian Priest and Scarlett (on behalf of Karrion Kross). Balor would then successfully defend the championship in a rematch against O'Reilly on 6 January 2021 at NXT: New Year's Evil. He would also defend the championship against Pete Dunne and Adam Cole at NXT TakeOver: Vengeance Day on 14 February and on 10 March episode of NXT respectively with both times successfully defending it.

After signing with WWE's developmental system, NXT, and adopting his current ring name, Bálor won the NXT Championship, and he was the longest reigning champion at 292 days until Adam Cole broke the record on 19 March 2020. Also during his time in NXT, Bálor became the first co-winner of the inaugural Dusty Rhodes Tag Team Classic with Samoa Joe. Shortly after arriving on the main roster, Bálor became the first wrestler in WWE history to win a world title in their pay-per-view debut, the second ever Irish world champion in WWE (after Sheamus) as well as becoming the quickest wrestler in WWE history to win a world title at 27 days following his main roster debut by becoming the inaugural WWE Universal Champion at SummerSlam 2016. During his time on the main roster, Bálor was also a two-time Intercontinental Champion and a one-time United States Champion.

After defeating Tyler Breeze on 20 May at NXT TakeOver: Unstoppable, Bálor received another title shot against Owens on 4 July at The Beast in the East in Tokyo, Japan, defeating Owens to win the NXT Championship.

Bálor wrestled his final NXT match on 30 July, teaming with Shinsuke Nakamura to defeat Bobby Roode and Samoa Joe.

After a near two-month absence from television, Bálor made his return to WWE programming on 2 October episode of NXT, confronting NXT Champion Adam Cole following the latter's title defense against Matt Riddle and officially announced his return to NXT (as it had grown from a developmental territory in Bálor's first stint into a third global brand within WWE). On 23 October episode of NXT, Bálor turned heel when he aided The Undisputed Era by injuring Johnny Gargano and attacking Tommaso Ciampa. Bálor began a feud with Matt Riddle the next month leading to a match between the two being scheduled for NXT TakeOver: WarGames on 23 November, where Bálor emerged victorious. Following this, Bálor challenged Adam Cole for the NXT Championship on 18 December episode of NXT, which he lost after a distraction from the returning Johnny Gargano.

On 22 April 2020 episode of NXT, Bálor was scheduled to have a match against Velveteen Dream, but Bálor was knocked out by an unknown attacker before he could leave his dressing room. Two weeks later, Bálor concluded that there was a "snake hiding in the long grass back there" and that whoever attacked him wanted a push. Bálor assured the audience that it won't be a push, but rather a squash. Later that night he got in an altercation with Cameron Grimes which resulted in a match between the two the next week. On 13 May episode of NXT, Damian Priest cost Bálor the match by using a nightstick behind the referee's back, and Priest then revealed that he was the one who knocked out Bálor three weeks prior, thus turning Bálor face once again. At TakeOver: In Your House on 7 June, Bálor defeated Priest. At NXT TakeOver: XXX on 22 August, Bálor defeated Timothy Thatcher.

On 16 December at the TLC: Tables, Ladders & Chairs event, Bálor gained revenge over McIntyre as he defeated him in a singles match after interference by McIntyre's former ally Dolph Ziggler. After the match, Ziggler would attack Bálor backstage after the latter implied that he didn't need his help to beat McIntyre. This sparked a match between the two that took place the following night on Raw, which ended in a no contest as McIntyre would attack both of them. On 17 December tapings of 24 December edition of Raw, Bálor defeated Ziggler and McIntyre a triple threat match, ending the feud. On 12 January 2019 at NXT UK TakeOver: Blackpool, Bálor made a surprise appearance as Travis Banks's replacement in his match against Jordan Devlin, as Banks was attacked by Devlin earlier that day, and subsequently defeated Devlin. On 14 January episode of Raw, after Braun Strowman was removed from his Universal Championship match against Brock Lesnar at the Royal Rumble after damaging Vince McMahon's limo, Bálor was booked in a fatal-four way match against Drew McIntyre, John Cena and Baron Corbin to determine who would take Strowman's place against Lesnar at the pay-per-view, in which Bálor emerged victorious after pinning Cena.

When he signed with WWE, Devitt worked under two characters: Finn Bálor (named after the legendary Irish hero Fionn mac Cumhaill and Balor of the Evil Eye, an antagonistic character from Gaelic mythology) and The Demon (sometimes the Demon King), a darker and more aggressive otherworldly alter-ego. After Devitt returned to NXT in 2019, he said he will use the character of The Demon less as its overuse had ruined the element of surprise.

On 19 August 2019, Devitt married Mexican sports journalist Vero Rodríguez in a private ceremony in Tulum. They had confirmed their relationship in June that year, during an interview at the UEFA Champions League final, and Devitt proposed to Rodríguez the following day. They reside in Orlando, Florida.

On 1 January 2018 episode of Raw, Bálor teamed with Luke Gallows and Karl Anderson to defeat Elias and The Miz Touareg (Curtis Axel and Bo Dallas) in a six–man tag team match. The following week, the trio officially reunited and formed "Bálor Club", an homage to their former stable. That same night, they defeated Intercontinental Champion Roman Reigns and Raw Tag Team Champions Seth Rollins and Jason Jordan in a six–man tag team match. On 28 January, at the 2018 Royal Rumble, Bálor entered his first Royal Rumble match at number 2, lasting over 57 minutes and eliminating four participants before being eliminated by John Cena. Bálor competed for the first time in an Elimination Chamber match at the namesake pay–per–view on 25 February, where he entered last but was the second participant eliminated by Braun Strowman. Over the next two months, Bálor started a short feud with The Miz and Seth Rollins over the Intercontinental Championship, which led to a triple threat match at WrestleMania 34 on 8 April (which was also Bálor's Wrestlemania debut) where Rollins won the title. At the Greatest Royal Rumble event on 27 April, Bálor once again unsuccessfully challenged for the Intercontinental Championship in a fatal four–way ladder match against Rollins, Miz and Samoa Joe. Bálor competed in a Money in the Bank ladder match on 17 June, however, the match was ultimately won by Braun Strowman.

On 22 February 2017, Bálor returned to NXT to assist Shinsuke Nakamura, who was outnumbered by Andrade "Cien" Almas and Bobby Roode. On 10 March, Bálor made his in–ring return at a live event in a six–man tag team match, teaming with Chris Jericho and Sami Zayn to defeat Kevin Owens, Samoa Joe and Triple H. Bálor made his television return after WrestleMania 33 on 3 April episode of Raw, where he teamed with his former rival Seth Rollins as the two defeated Owens and Joe in a tag team match. Over the following weeks, Bálor would score victories over Jinder Mahal and Curt Hawkins while also receiving an ominous warning from Bray Wyatt and confronting Luke Gallows and Karl Anderson. On 4 June at Extreme Rules, Bálor competed in a fatal five–way extreme rules match to determine the number one contender for Brock Lesnar's Universal Championship, in which Bálor lost after he passed out from Samoa Joe's Coquina Clutch.

On 19 July 2016, Bálor was drafted to the Raw brand as the fifth overall pick in the 2016 WWE draft, later declaring that he should have been the first pick. He made his first appearance for the brand on 25 July episode of Raw (on his 35th birthday), where he won the right to compete for the newly established WWE Universal Championship at SummerSlam by first defeating Rusev, Cesaro, and Kevin Owens in a fatal four–way match and then defeating Roman Reigns, who had won a similar fatal four–way match. At SummerSlam on 21 August, Bálor defeated Seth Rollins to become the inaugural Universal Champion and win his first world title. Since then, WWE reported that he sustained a shoulder injury during the match and an MRI revealed a labrum tear that would require surgery, which was successful. Because of this, it was expected that Bálor would be out four to six months, thus Raw General Manager Mick Foley later announced on Twitter that Bálor would be relinquishing his newly won WWE Universal Championship due to his injury after just 22 hours of holding it. While recovering from his injury, Bálor would appear on the WWE Network–exclusive United Kingdom Championship Tournament event.

On 4 January 2014 at Wrestle Kingdom 8 in Tokyo Dome, Devitt's fourteen-month reign as the IWGP Junior Heavyweight Champion came to an end when he lost the title to Kota Ibushi in his fifth defense. Devitt wrestled the entire match in a full face and body paint, which he continued using for his bigger matches for the rest of his NJPW run. The following day, Devitt was attacked by the returning Ryusuke Taguchi, who had been sidelined with an injury for the past seven months, re-igniting the rivalry between the two former partners. On 6 April at Invasion Attack 2014, one year after the break-up of Apollo 55, Devitt faced Taguchi in a singles grudge match. During the match, Devitt repeatedly told The Young Bucks (Matt and Nick Jackson), the two newest members of Bullet Club, not to interfere in the match, which eventually led to them turning on him. In the end, Taguchi defeated Devitt, after which the two men shook hands, ending their rivalry with each other. The following day, New Japan announced Devitt's resignation from the promotion.

On 15 May 2014, Devitt was reported to have signed with WWE and would join NXT - then the promotion's developmental territory - once he obtained a visa. On 28 July, WWE officially confirmed Devitt's signing, announcing he would report to NXT that same day. On 24 September, his new ring name was revealed to be Finn Bálor, derived from Irish mythological figures Fionn mac Cumhaill and Balor (the latter is also Gaelic for "Demon King"). Bálor made his NXT debut the next day, aiding Hideo Itami against The Ascension (Konnor and Viktor). In his debut match on 23 October, he and Itami defeated Justin Gabriel and Tyson Kidd. After feuding with The Ascension, Bálor and Itami defeated them at NXT TakeOver: R Evolution on 11 December, where he also debuted his signature body paint. Bálor then entered an NXT Championship number one contender's tournament, defeating Curtis Axel in the first round, Itami in the semi-finals and Adrian Neville in the finals on 11 February at NXT TakeOver: Rival. Bálor received his title match against Kevin Owens on 25 March, but was unsuccessful.

Devitt returned to New Japan on 8 October at King of Pro-Wrestling, challenging IWGP Junior Heavyweight Champion Low Ki to a title match, after he had regained the title from Kota Ibushi. On 21 October, Apollo 55 entered the 2012 Super Jr. Tag Tournament, defeating Chaos World Wrestling Warriors (Brian Kendrick and Low Ki) in their first round match. On 2 November, Devitt and Taguchi defeated the reigning IWGP Junior Heavyweight Tag Team Champions, the Forever Hooligans (Alex Koslov and Rocky Romero), to advance to the finals of the tournament, where, later that same day, they were defeated by the Time Splitters (Alex Shelley and Kushida). On 11 November at Power Struggle, Devitt defeated Low Ki to win the IWGP Junior Heavyweight Championship for the third time. On 4 January 2013 at Wrestle Kingdom 7 in Tokyo Dome, Devitt defeated Low Ki and Kota Ibushi in a rare three-way match for his first successful defense of the title. Following his win, Devitt accepted a challenge for the title made by his tag team partner, Ryusuke Taguchi. On 3 February, Devitt picked up a big win, when he pinned reigning IWGP Heavyweight Champion Hiroshi Tanahashi in a tag team match, where he and Karl Anderson faced Tanahashi and Taguchi. Seven days later, Devitt defeated Taguchi at The New Beginning for his second successful defense of the IWGP Junior Heavyweight Championship. On 3 March, Devitt main evented New Japan's 41st anniversary event, losing to Hiroshi Tanahashi in a non-title match. Following the loss, Devitt began portraying a more cocky and villainous persona, regularly disrespecting both partners and opponents, with the exception of Ryusuke Taguchi, whom he tried to get to go along with his new attitude. On 5 April, Devitt defeated Alex Shelley for his third successful defense of the IWGP Junior Heavyweight Championship. Two days later at Invasion Attack, Apollo 55 unsuccessfully challenged Time Splitters for the IWGP Junior Heavyweight Tag Team Championship, after which Devitt turned on Taguchi, ending the longtime partnership between the two, and debuted Bad Luck Fale as his new "bouncer", while also dubbing himself the "Real Rocknrolla".

The first match between the former members of Apollo 55 took place on 3 May at Wrestling Dontaku 2013, where Devitt and Fale defeated Taguchi and Captain New Japan in a tag team match. Later in the event, Devitt and Fale were joined by Karl Anderson and Tama Tonga for an attack on Hiroshi Tanahashi. The new group was subsequently named "Bullet Club". On 24 May, Devitt entered the 2013 Best of the Super Juniors, where he ended up winning his block with a clean record of eight wins, though often using outside help from his Bullet Club stablemates to win his matches. On 9 June, Devitt first defeated Kenny Omega in the semifinals and then Alex Shelley in the finals to win his second Best of the Super Juniors. Following his win, Devitt challenged Hiroshi Tanahashi, while also naming his next goal; becoming the first wrestler to hold the IWGP Junior Heavyweight and IWGP Heavyweight Championships simultaneously.

On 22 June at Dominion 6.22, Devitt defeated Tanahashi with help from Bullet Club to earn his first shot at the IWGP Heavyweight Championship. Later in the event, reigning IWGP Heavyweight Champion Kazuchika Okada accepted Devitt's challenge for his title on the condition that he first defend the IWGP Junior Heavyweight Championship against his Chaos stablemate Gedo. On 5 July, Devitt defeated Gedo in his fourth successful title defense, advancing to the IWGP Heavyweight Championship match against Okada. The title match between the two took place on 20 July and saw Okada defeat Devitt, despite interference from the rest of Bullet Club, to retain his title. On 1 August, Devitt defeated Okada, with help from Fale, in the main event of the first day of the 2013 G1 Climax. Despite three other big wins over former IWGP Heavyweight Champions Hiroshi Tanahashi, Satoshi Kojima, and Togi Makabe, Devitt failed to advance from his block, finishing with a record of five wins and four losses. The rivalry between Devitt and Tanahashi culminated in a Lumberjack Deathmatch on 29 September at Destruction, where Tanahashi was victorious.

With the Tanahashi rivalry behind him, Devitt moved onto a new rivalry with Togi Makabe, who played a big part in him losing the Lumberjack Deathmatch. Meanwhile, Devitt also found himself a new challenger for the IWGP Junior Heavyweight Championship, recent NJPW signee Kota Ibushi, who pinned him a tag team match on 9 November at Power Struggle, where he and Bad Luck Fale were defeated by Ibushi and Makabe. From 23 November to 7 December, Devitt and Fale took part in the 2013 World Tag League, where they finished with a record of three wins and three losses, with a loss against the previously winless Captain New Japan and Hiroshi Tanahashi on the final day costing them a spot in the semifinals.

On 30 May, Devitt entered the 2010 Best of the Super Juniors tournament and two weeks later finished second in his block with five victories, advancing to the semifinals of the tournament. On 13 June, Devitt first defeated Taiji Ishimori in the semifinals and then Kota Ibushi in the finals to win the tournament and earn a shot at Naomichi Marufuji's IWGP Junior Heavyweight Championship. On 19 June at Dominion 6.19, Devitt defeated Marufuji to win the IWGP Junior Heavyweight Championship for the first time. Eleven days later, Devitt, Taguchi and Hirooki Goto won the J Sports Crown Openweight 6 Man Tag Tournament, defeating Hiroshi Tanahashi, TAJIRI and Kushida in the finals.

Just over a week later, on 19 July, Devitt and Taguchi defeated Koji Kanemoto and El Samurai to win the IWGP Junior Heavyweight Tag Team Championship for the second time as a team. In August Devitt entered New Japan's biggest tournament of the year, the G1 Climax, as a substitute for the injured Naomichi Marufuji. Devitt managed to win four out of his seven matches in the round-robin stage of the tournament, including a major victory over former four-time IWGP Heavyweight Champion Hiroshi Tanahashi, but finished fifth in his block and missed advancing to the finals by a single point. On 3 September, Devitt made his second successful defense of the IWGP Junior Heavyweight Championship, defeating DDT Pro-Wrestling representative Kenny Omega, that he won on 11 November 2012. Omega and Kota Ibushi, the team known collectively as the Golden☆Lovers, came back on 11 October at Destruction '10 and defeated Devitt and Taguchi to win the IWGP Junior Heavyweight Tag Team Championship.

On 23 June, Devitt, Taguchi and Hirooki Goto won their second J Sports Crown Openweight 6 Man Tag Tournament in a row by defeating the team of Giant Bernard, Jushin Thunder Liger and Karl Anderson in the finals of the three-day-long tournament. On 24 July, Devitt received his rematch for the IWGP Junior Heavyweight Championship at Ryōgoku Peter Pan 2011, but was unable to regain the title from Ibushi. This led to a match on 14 August, where Apollo 55 successfully defended the IWGP Junior Heavyweight Tag Team Championship against the Golden☆Lovers. On 11 September, Apollo 55 defeated Taichi and Taka Michinoku to make their seventh successful IWGP Junior Heavyweight Tag Team Championship defense, breaking the record for most defenses during a single reign. When Kota Ibushi was forced to vacate the IWGP Junior Heavyweight Championship after dislocating his left shoulder, Devitt, as the previous champion, was ushered into a decision match to determine a new champion. On 19 September, Devitt defeated Kushida to win the IWGP Junior Heavyweight Championship for the second time. On 10 October at Destruction '11, Devitt and Taguchi lost the IWGP Junior Heavyweight Tag Team Championship to the No Remorse Corps (Davey Richards and Rocky Romero). Devitt made the first successful title defense of his second IWGP Junior Heavyweight Championship reign on 12 November at Power Struggle, defeating Taka Michinoku, and followed that up by defeating the man who had pinned him for the IWGP Junior Heavyweight Tag Team Championship, Davey Richards, in his second defense on 4 December.

On 12 February at The New Beginning, Apollo 55 lost the IWGP Junior Heavyweight Tag Team Championship back to the No Remorse Corps in their first defense. This led to a match on 10 March, where Devitt defeated Davey Richards to make his fourth successful defense of the IWGP Junior Heavyweight Championship.

On 14 March 2012, Devitt traveled to Mexico for his first tour of the country with the Consejo Mundial de Lucha Libre promotion, as part of a working relationship between New Japan and CMLL.

On 18 June at Dominion 6.18, Devitt lost the IWGP Junior Heavyweight Championship to Best of the Super Juniors winner, Kota Ibushi, ending his reign at 364 days.

Devitt is widely known for his tenure with New Japan Pro-Wrestling (NJPW) as Prince Devitt, where he is a three-time IWGP Junior Heavyweight Champion and six-time IWGP Junior Heavyweight Tag Team Champion, having held the title twice with Minoru and four times with Ryusuke Taguchi. He is also a two-time winner of the Best of the Super Juniors tournament, having won in 2010 and 2013, as well as being a founding member and the original leader of the Bullet Club stable. Through NJPW's working relationship with Mexican promotion Consejo Mundial de Lucha Libre (CMLL), Devitt also wrestled there, becoming a one-time NWA World Historic Middleweight Champion. He also wrestled for a number of independent promotions, becoming a one-time ICW Zero-G Champion, one-time RPW British Cruiserweight Champion and a two-time NWA British Commonwealth Heavyweight Champion.

Devitt teamed with Ryusuke Taguchi as Apollo 55 (アポロ・ゴー・ゴー, Aporo Gō Gō) and on 5 July 2009 at Circuit 2009 New Japan Soul they defeated The Motor City Machine Guns (Alex Shelley and Chris Sabin) to win the IWGP Junior Heavyweight Tag Team Championship. On 30 May, Devitt entered the 2009 Best of the Super Juniors tournament.

In the end, Devitt was defeated in the finals of the tournament by Koji Kanemoto. In December, Devitt entered the 2009 Super J-Cup. After defeating Atsushi Aoki, Danshoku Dino and Yamato, Devitt was once again defeated in the finals of the tournament, this time by Naomichi Marufuji. On 4 January 2010, at Wrestle Kingdom IV in Tokyo Dome, Devitt and Taguchi successfully defended the IWGP Junior Heavyweight Tag Team Championship against Averno and Último Guerrero. On 21 April, Devitt and Taguchi were stripped of the title, after not defending them for 30 days. On 8 May, the two entered the Super J Tag Tournament in an attempt to regain the championship, but were defeated in the finals by the team of El Samurai and Koji Kanemoto.

On 27 January 2008, Devitt and Minoru won the IWGP Junior Heavyweight Tag Team Championship, this served as Devitt's first major tag title reign. They lost the championship to Akira and Jyushin Thunder Liger in February, before regaining the title on 21 July. After a near three-month reign they lost the championship to No Limit (Tetsuya Naito and Yujiro) in October.

In June 2007, Devitt participated in a tournament for the National Wrestling Alliance (NWA) called "Reclaiming the Glory", which was to crown a new NWA World Heavyweight Champion. The championship had been controlled by Total Nonstop Action Wrestling (TNA) for several years, but in 2007 NWA had terminated its agreement with TNA. In the first round, Devitt defeated Australian wrestler Mikey Nicholls, but lost in the second round to Bryan Danielson.

His momentum was halted in January 2007, when he suffered a serious knee injury, sidelining him from in-ring action in New Japan until early May of that year. Following the injury, he returned to action, showing great improvement and was touted by fellow CTU teammate, Minoru, as the future winner of the 2007 Best of the Super Juniors tournament. However, when the tournament was held in June 2007, Devitt scored no points and was eliminated early from the competition. Following the folding of CTU in August 2007, Devitt and Minoru joined the new RISE stable, forming a tag team named "Prince Prince", a reference to both Devitt's ring name and Minoru's nickname, "Black Prince". In November 2007, TNA made a tour of Japan, during which Devitt and Minoru were defeated by TNA wrestlers Senshi and Christopher Daniels.

The day after losing the British Commonwealth Championship, Devitt signed a contract with New Japan Pro-Wrestling (NJPW) in March 2006. In April 2006, he made his NJPW debut against El Samurai, using the ring name Prince Devitt. Devitt later stated in an interview with PowerSlam Mag that New Japan renamed him Prince Devitt because nobody Japanese could pronounce his actual name. He was originally going to be called King David until people started questioning why the 24-year-old would be a king already. Eventually, Simon Inoki came up with the name Prince Devitt, which Devitt himself also preferred. In May 2006, New Japan started holding brand–exclusive events, and Devitt was assigned to the Wrestle Land brand, debuting under a mask as the second Pegasus Kid, which led to comparisons between Devitt and the original Pegasus Kid, Chris Benoit.

On 8 October 2005, in Nashville, Tennessee, at the NWA 57th Anniversary Show, Devitt defeated Dru Onyx for his second British Commonwealth title. After the match both participants were invited to the New Japan Inoki Dojo in Santa Monica, California to train. During late 2005, Devitt also began competing for the U.S.–based Millennium Wrestling Federation (MWF).
