The Undisputed Era was a professional wrestling stable from WWE's NXT brand. It formed on August 19, 2017, at NXT TakeOver: Brooklyn III shortly after Adam Cole, Bobby Fish, and Kyle O'Reilly signed with WWE, although Fish and O'Reilly had already been a tag team since 2012 under the name reDRagon. After, Fish suffered an injury in March 2018, April 7 at NXT TakeOver: New Orleans marked a turning point for the Undisputed Era: during the event, Cole became the inaugural NXT North American Champion, he and O'Reilly won the 2018 Dusty Rhodes Tag Team Classic, and Roderick Strong joined the stable at the end of a lengthy feud against it; both Cole and Strong were subsequently recognized as co-Tag Team Champions under the Freebird Rule. O'Reilly later had two more additional reigns as NXT Tag Team Champion, one with Strong and one with Fish, while Cole became NXT Champion at NXT TakeOver: XXV, becoming NXT's second Triple Crown winner. On September 18, Strong won the NXT North American Championship, making the Undisputed Era the first stable to simultaneously hold all the male titles on NXT. All four stayed champions until January 22, 2020, when Strong lost his title to Keith Lee.
