Anderson and Blanchard adopted this name after joining the WWF in 1988 after leaving Jim Crockett Promotions, where the two men had wrestled as part of The Four Horsemen stable and had won the NWA World Tag Team Championship twice.
[8] Arn and Tully regained the titles less than a month later on April 20, 1988 when Barry Windham turned on his tag-team partner and joined the Four Horsemen.
[6] The duo would mainly defend the titles against various combinations of teams between the trio of Sting, Nikita Koloff and "Dr. Death" Steve Williams.
[2] Things began to sour behind the scenes for the champions, as the National Wrestling Alliance (NWA) launched its first-ever uninterrupted pay-per-view, The Great American Bash, promoters were attempting to draw a large gate and, according to the DVD Ric Flair and The Four Horsemen, Blanchard had suggested a rematch with the Road Warriors, but instead they were booked against Sting and Koloff, (whom they wrestled to a time limit draw), and when the PPV payouts were given out, it was discovered that Dillon who was their manager received 3 times the payout of the 2-time World Tag Team Champions.
The only changes Arn and Tully made to their style were pointing to their heads to show they were smarter than everyone else and the use of a spike piledriver as a finishing move.
After an even start, the Brain Busters dominated the ex-champions as Rick Martel walked out on Tito Santana and he was brutalized and beaten after a spike piledriver and eventually pinned.
[11] After their WrestleMania win, the Brain Busters finally got to face the WWF World Tag Team Champions Demolition and defeated them by disqualification on the May 27, 1989 Saturday Night's Main Event XXI.
Tully Blanchard would renegotiate a new contract with NWA a few months later, but ultimately declined what he considered to be a very low offer (reportedly half of a previous verbal agreement), and instead signed with the American Wrestling Association (AWA).
