On June 1, 2010, Rotunda was announced as a competitor in the second season of WWE NXT under the name Husky Harris, with Cody Rhodes as his mentor. Harris made his debut on the June 8 episode of NXT, competing in a tag team match with Rhodes against Montel Vontavious Porter and Percy Watson, which they lost. After a rocky start with his pro Cody Rhodes, Harris turned heel on the June 22 episode of NXT by attacking announcer Matt Striker, just as Rhodes had done the previous week. The following week, Harris lost to Porter in a singles match, and was ranked seventh out of the eight rookies in the first poll. In the second poll, Harris moved up to sixth place, narrowly avoiding elimination. On August 9 the rookies appeared in a six-man tag team match on Raw, which Harris' team won when he pinned Kaval, but his team lost a rematch the following night on NXT. In the poll later that night, Harris climbed to fourth place out of the six rookies. Harris was one of two rookies eliminated from NXT on August 17. Following his elimination, Harris and Rhodes attacked Kaval, resulting in a brawl also involving Porter and Kofi Kingston. Harris reappeared in the season finale of NXT with the other eliminated rookies and joined in on the attack on the NXT winner, Kaval.
While on NXT, Rotunda continued wrestling in FCW while retaining the Husky Harris ring name. In September 2010 following his elimination from NXT, Harris began a feud in FCW with Percy Watson when he attacked Watson while teaming with him in a tag team match, which led to Watson being pinned for the loss. When Harris and Watson faced off in a match, they were both counted out as they brawled out of the arena. The next week, Watson defeated Harris in a no disqualification match. The feud ended in October with Harris defeating Watson in a lumberjack match.
At the Hell in a Cell pay-per-view in October, a disguised Harris and Michael McGillicutty interfered in a match between John Cena and Wade Barrett, and helped Barrett win, forcing Cena to join Barrett's factionthe Nexus per the pre-match stipulation. Harris' and McGillicutty's identities were revealed on the following day's episode of Raw, though Barrett claimed he had not asked for their help and refused to make them full-time members of The Nexus. The following week, Harris and McGillicutty cost Cena a match against The Miz, prompting Barrett to give them the opportunity to win membership in the Nexus. On the October 18 episode of Raw, Harris and McGillicutty failed to earn a place in the Nexus when they lost to Cena and Randy Orton in a tag team match. Despite of their loss, Harris and McGillicutty were inducted into the Nexus on Raw the following week. In January 2011, CM Punk took over the Nexus and had each of its members put through an initiation. Harris passed his initiation, a lashing from the rest of the group, and was allowed to remain a member of the New Nexus, alongside Punk, McGillicutty and David Otunga. Three weeks later, on the January 31 episode of Raw, Harris and McGillicutty unsuccessfully challenged Santino Marella and Vladimir Kozlov for the WWE Tag Team Championship. After the match, Orton attacked them as revenge for costing him the WWE Championship, and punted Harris in the head, which was used to write Harris off television "indefinitely".
Return to FCW (2011–2012)
Following the punt by Orton on Raw, Rotunda returned to FCW and debuted a new character in March 2011, that of the hockey mask-wearing Axel Mulligan, but the character never made it to FCW TV, and Rotunda continued to play the Husky Harris character on FCW TV. In August 2011, Harris became embroiled in his brother Bo's (the FCW Florida Heavyweight Champion) feud with Lucky Cannon and Damien Sandow; the brothers later teamed up to defeat Cannon and Sandow in a tag match. Later, Harris voiced his displeasure of Bo's relationship with Aksana, and when Bo suffered an injury, his title was vacated and a tournament set up to determine the new champion; Harris defeated Big E Langston to make it to the final, a fatal four-way match against Dean Ambrose, Leo Kruger and Damien Sandow. During the match, won by Kruger, Harris was superkicked by Richie Steamboat at ringside who was aiming for Ambrose. The next week, a scheming Aksana managed to get Steamboat to attack Harris again; Harris also won a triple threat match against Ambrose and Sandow to earn a match for the championship against Kruger, which Harris lost when he was distracted with Steamboat's interference. As a result, Harris and Steamboat began feuding, with their first match ending in a no contest. Kruger later defeated the pair in a triple threat match to retain his heavyweight title, and the following week, Harris defeated Steamboat in a No Holds Barred match. After the pair continued to frequently attack each other, they were suspended for 30 days. Upon their return, Harris defeated Steamboat in a Bullrope match to end their feud. On February 2, 2012, Harris and Bo defeated Brad Maddox and Eli Cottonwood to win the (vacant) Florida Tag Team Championship for the second time. The brothers successfully defended their titles against Antonio Cesaro and Alexander Rusev, but lost their titles to Corey Graves and Jake Carter on March 15.
From the May 27 episode of Raw, WWE aired vignettes promoting the upcoming debut of the Wyatt Family. The vignettes showed the Wyatt Family's backwoods origins and Rowan wearing a lamb mask. On the July 8 episode of Raw, the Wyatt Family made their debut by assaulting Kane. The Wyatt Family continued their attacks on wrestlers like R-Truth, Justin Gabriel and 3MB (Drew McIntyre, Heath Slater, and Jinder Mahal) while sending cryptic messages to Kane asking him to "follow the buzzards". Following another assault, Kane challenged Wyatt to a Ring of Fire match at SummerSlam, which he accepted. On August 18 at the pay-per-view, Wyatt defeated Kane in the Ring of Fire match, following interference from Harper and Rowan. After the match, Harper and Rowan again attacked Kane and ended the segment by carrying him away. Wyatt's next target was Kofi Kingston, who he defeated at WWE Battleground.
The Wyatt Family's next feud began when they attacked Daniel Bryan and CM Punk in late October, leading to Bryan and Punk defeating Harper and Rowan at Survivor Series. The Wyatt Family continued their feud with Bryan as Wyatt attempted to recruit Bryan, and the trio defeated Bryan in a handicap match at TLC: Tables, Ladders & Chairs. On the final Raw of 2013, Bryan defeated Harper and then Rowan in a gauntlet match so that he could face Wyatt, whereupon Harper and Rowan interfered for a disqualification and beat him down. A frustrated Bryan finally gave up and gave in to join the Wyatt Family. However, after Bryan joined them, the Wyatt Family could not find success. This caused Wyatt to punish Bryan, leading to Bryan attacking all the other members of the Wyatt Family on the January 13 Raw to signal him breaking free of the group. They interfered in John Cena and Randy Orton's match at the Royal Rumble 2014 PPV for the WWE World Heavyweight Championship, causing the distraction of Cena allowing Orton to perform the RKO and pinning Cena. After the bout, The Wyatts would attack Cena, with Bray hitting Cena with the Sister Abigail, signalling a feud between Bray Wyatt & John Cena

He's evil, scary but not over the top. He comes across as having genuinely done something evil like murder, but justifies it through the faith he follows (which faith we aren't told)."
