In another time line Fury loses to Wilder the first time due to Wilders high ring IQ which gassed Fury out, with Wilder winning a 8th round KO . Fury gets a few contender wins then gets outclassed by slick Otto Wallin, Fury retires and becomes a stripper. Fury comes out of retirement in 2031 and beats the reigning undisputed champ Luis Ortiz who is now 137 years old.
