Evil Uno

Evil Uno and Stu Grayson made their surprise debut as The Dark Order at AEW Double or Nothing on May 25, 2019, appearing at the conclusion of the match between Best Friends and Angélico and Jack Evans. After the match was over, the lights went out and when they came back on, Uno and Grayson were in the ring. The lights went out a second time and when they came back on, masked henchmen surrounded the ring. The Order then attacked all four men. After the attack, the lights went out again and they disappeared.

Uno last appeared for Ring of Honor on May 11, 2018 at the War of the Worlds event in Toronto, Canada when the Super Smash Brothers faced the Young Bucks in a losing effort.

In Chikara, Player Uno became popular for basing his gimmick, moveset, and attire around video games, specifically games for the NES and SNES consoles. One of his former trademarks was his pants, which had an NES controller design on one side; if the "Pause" button was pressed, he would stop moving, and if his opponent hit him while he was "paused", Player Uno wouldn't react until getting "unpaused". He was also famous for wearing gear in the color schemes of characters such as Mario, Luigi, and Wario. In recent years, Player Uno has stopped using both distinctive traits. In 2015, Dansereau repackaged himself as Evil Uno.

Uno is heavily involved in the charity "Fighting Back", which was set up in memory of professional wrestler Phrank Morin to raise money for the Canadian Cancer Society. Uno and his partner Player Dos have been part of multiple wrestling events for the charity since its creation in 2011. On August 14, 2015, during a 24-hour gaming stream for the charity, Uno and Dos were given the nicknames "The Big Dog" and "The Wildcat" respectively by the video game streaming group, newLEGACYinc, who were running the Fighting Back stream that year. Uno and Dos debuted their new nicknames at the 2015 Fighting Back: Wrestling with Cancer event the next day, while teaming with Último Dragón in a Trios match against Pinkie Sanchez and EYFBO.

On May 25, the Super Smash Bros. defeated The Young Bucks in a No Disqualification match to win the vacant PWG World Tag Team Championship. The Super Smash Bros. made their first successful title defense on July 21 at Threemendous III, PWG's nine-year anniversary event, where they defeated Future Shock and The Young Bucks in a three-way ladder match. On December 1 at Mystery Vortex, the Super Smash Bros. made their second successful World Tag Team Championship defense against the RockNES Monsters. Later that same event, they were defeated by the Dojo Bros (Eddie Edwards and Roderick Strong) in a non-title match. On January 12, 2013, the Super Smash Bros. lost the World Tag Team Championship to the Unbreakable F'n Machines (Brian Cage and Michael Elgin) in the opening round of the 2013 Dynamite Duumvirate Tag Team Title Tournament. During the match, Uno suffered a dislocated shoulder after performing a suicide dive to the outside of the ring.

Formerly known as Player Uno, he regularly teamed with Stu Grayson as the Super Smash Brothers for various independent promotions across North America, including Alpha-1 Wrestling, Capital City Championship Combat (C*4), Inter Species Wrestling (ISW), and California-based Pro Wrestling Guerrilla (PWG). Together, they are former one-time Chikara Campeones de Parejas, one-time PWG World Tag Team Champions and winners of PWG's 2012 Dynamite Duumvirate Tag Team Title Tournament.

On January 28, 2012, the Super Smash Bros. made their debut for Dragon Gate USA, defeating The Scene (Caleb Konley and Scott Reed) in a tag team match. The following day, they picked up another win over the D.U.F. (Arik Cannon and Pinkie Sanchez), after which Uno asked for a shot at the Open the United Gate Championship. The Super Smash Bros.' win streak ended on November 2, when they were defeated by Genki Horiguchi and Ryo Saito in an Open the United Gate Championship number one contenders' match.

On December 24, 2012, Uno appeared on a new YouTube channel called, TheNerdSlam. He, along with a group of friends, created the channel, which consists of two different webshows. One called 4-Play where Uno plays various video games with friends. The other is a food show called Stu's Kitchen, hosted by Stupefied.

On September 10, 2011, Uno debuted in Pro Wrestling Guerrilla (PWG) as a member of the Super Smash Bros. with Stupefied. In their debut match, they faced the RockNES Monsters (Johnny Goodtime and Johnny Yuma), a tag team with a similar video game-themed gimmick, in a losing effort. The Super Smash Bros. returned on December 10, 2011, this time losing a match against the American Wolves (Davey Richards and Eddie Edwards). The Super Smash Bros. picked up their first win in PWG on March 17, 2012, by defeating former two-time PWG World Tag Team Champions, The Young Bucks (Matt and Nick Jackson), and the RockNES Monsters in a three-way match. On April 21, the Super Smash Bros. defeated The Young Bucks in the opening round, Future Shock (Adam Cole and Kyle O'Reilly) in the semifinal, and 2 Husky Black Guys (El Generico and Willie Mack) in the final round to win the 2012 Dynamite Duumvirate Tag Team Title Tournament and become number one contenders to the PWG World Tag Team Championship.

Uno made his debut in the Canadian wrestling promotion International Wrestling Syndicate (IWS). Uno quickly found a tag team partner in Stupefied as the Super Smash Brothers. The team found success as they soon won the IWS Tag Team Championship. Uno also found success as a singles competitor as he also won the IWS Canadian Championship. He remained with the promotion until it folded on October 9, 2010.

Uno, along with Player Dos, made his ROH debut on May 8, 2009 in Boston, MA, in a losing effort against Rhett Titus and Kenny King. On July 25 in Toronto, Ontario, at Death Before Dishonor VII Night 2 they scored an upset victory over former ROH World Tag Team Champions Kevin Steen and El Generico. On the November 9 episode of Ring of Honor Wrestling on HDNet, Uno and Dos debuted on the show in a return match, where they were defeated by Steen and Generico.

In 2007 the team started competing in Chikara. Uno and Stupefied, now competing as Player Dos and naming their team the Super Smash Brothers, won the Chikara Campeonatos de Parejas from Incoherence (Delirious and Hallowicked) at Laying in the Gutters, Looking at the Stars on September 21, 2008. The team only held the titles for a month before losing it to The Osirian Portal, the team of Amasis and Ophidian, at Global Gauntlet: Night 2. In 2009 Uno went on a long losing streak, which included a loss against Player Dos for the Young Lions Cup, but the streak came to an end at the season finale, when he debuted his new finishing maneuver The Joystick and forced Tim Donst to tap out with it. On October 24, 2010 Uno wrestled to date his last Chikara match with Dos with Sara Del Rey and Daizee Haze, which Uno and Dos lost.

Nicolas Dansereau (born July 20, 1987), better known as Evil Uno, is a Canadian professional wrestler. He is currently signed to All Elite Wrestling (AEW), where he is part of the Dark Order stable.
