Old rivalries are brought to the forefront as previous "Ink Master" contestants go head-to-head against their biggest rivals. Former champions Ryan Ashley (Season 8), DJ Tambe (Season 9 and Season 10), and Cleen Rock One (Season 11) return to the studio, bringing their experience back to the game as judges and possibly referees. The competition will turn nasty as the nation's best tattoo artists show off their talents and skills while simultaneously trying to take down their greatest adversaries from the series.
