Aces & Eights were a villainous stable in the American promotion Total Nonstop Action Wrestling (TNA, later Impact Wrestling), initially consisting of a group of masked wrestlers before their identities were revealed. It had the gimmick of a Vigilante Posse motorcycle club; members of the stable rode motorcycles, wore kuttes, and were referred to as either "prospects" or "patched in". The name of the stable is a reference to the two pair poker hand known as the "dead man's hand".

The stable debuted on the June 14, 2012, episode of Impact Wrestling, with three masked wrestlers attacking Sting as he discussed his induction to the TNA Hall of Fame. On the July 5 episode of Impact Wrestling, an unnamed man delivered an envelope to TNA General Manager Hulk Hogan containing a photograph of aces and eights playing cards (known as the "dead man's hand") and a note reading "see you next week", saying "we're not cowards... we've got something for you Hogan, wait and see!"

Aces & Eights returned (in greater numbers) to TNA on the July 12, 2012, episode of Impact Wrestling, attacking both Sting and Hogan, with Hogan billed as having sustained a pelvic fracture (providing a kayfabe explanation for his absence from television while recovering from surgery to alleviate back pain). Over the next several weeks, the stable continued to attack both faces and heels, they were initially introduced as a Vigilante Gang

Aces & Eights made its first appearance on pay-per-view at Hardcore Justice on August 12, 2012, attacking D'Angelo Dinero backstage (providing a kayfabe explanation for his absence from television to recuperate from a shoulder injury). Aces & Eights later interfered in a four-way tables match, attacking Jeff Hardy and the eventual winner, Bully Ray.

On the August 23, 2012, episode of Impact Wrestling, Aces & Eights brawled with members of the TNA roster, injuring the right arm of TNA World Heavyweight Champion Austin Aries. One week later, Aces & Eights attacked Aries again, knocking him unconscious with a foreign object. The following week on Impact Wrestling, a low-level member of Aces & Eights named Mike was interrogated by Austin Aries into leaking information about Aces & Eights, but Aces & Eights came out and knocked out Mike with a hammer to prevent him from revealing anything.

At No Surrender, on September 9, 2012, Aces & Eights again brawled with the TNA roster following a fight between Aries and a member called "The Armbreaker", injuring the shoulder of Jeff Hardy prior to his Bound for Glory series final against Bully Ray.

Aces & Eights wrestled its first match at the Bound for Glory pay-per-view on October 14, 2012, where two unnamed members of the stable defeated Sting and Bully Ray in a no disqualification tag team match to win unfettered access to the Impact Zone (Aces & Eights had agreed to leave TNA if they had lost). They won following interference from two other members of the stable, one of whom was subsequently unmasked and revealed as Devon, a member of the TNA roster and the former tag team partner of Bully Ray. Devon was the first member of Aces & Eights to be formally identified by TNA.

On the October 18, 2012, episode of Impact Wrestling, Devon, speaking for the gang (his vest identified him as "Sergeant-at-Arms"), threatened the TNA roster, who responded by attacking Aces & Eights. Sting challenged Devon to a match, which Sting won by disqualification when Aces & Eights interfered.
