F-Zero GX takes place 1 year after F-Zero X with Captain Falcon being the winner of the previous F-Zero Grand Prix.
Black Shadow is driving down a highway after losing a Grand Prix. Deathborn catches up to him and gives him one more chance to succeed but says it's the only other chance he'll get.
Captain Falcon begins training for the Grand Prix, followed by racing his rival, Samurai Goroh, in a desert canyon. When he goes to Bet Race & Dollars to relax, he is forced by Silver Neelsen to enter the bet race under the disguise of 'Famicom'. After winning said bet race, Falcon notices Black Shadow attacking the Lightning area on the news. Falcon makes his way to stop him, but is delayed by a group of thugs led by Michael Chain. After dealing with Chain's gang, Falcon enters a facility to save Jody Summer. He must escape the facility before the core detonates, with said facility going into lock-down procedures. With Jody out of harm's way, and reunited with John Tanaka, Falcon confronts Black Shadow. The evil overlord, with the help of Blood Falcon, bind Falcon and traps him inside his vehicle, strapping a bomb to the Blue Falcon that will detonate if the Blue Falcon goes below 700 km/h. Falcon manages to survive by driving the vehicle straight off an unfinished road and right under a crane, knocking the bomb off.
Falcon later attends the Grand Prix, racing against many pilots including Blood Falcon and Black Shadow. Falcon wins the Grand Prix and receives the champion's belt. He witnesses Black Shadow being punished by his master, Deathborn, for his incompetence. Deathborn challenges Falcon to a one-on-one race for ownership of both belts, Falcon’s champion belt and Deathborn’s champion belt from the Underworld Grand Prix. Before said race occurs, Deathborn reveals his plan to take over the universe, revealing the energies of light and dark are condensed in each belt, and that when combined, provide ultimate power that will turn him into a god-like being, able to lay waste to Falcon's galaxy. Falcon races against Deathborn and defeats him. With both belts united into one, Falcon vows to keep winning so he can protect the belt from the forces of evil.
At his garage, Falcon is greeted by the creators. Falcon figures out the creators were behind everything, though they do not elaborate their motives. They challenge Falcon to a race, where, if they win, will rip out Falcon's soul and turn it into their creation, implying that he would replace Deathborn. Falcon defeats them and the creators disappear. Falcon then removes his helmet and leaves the room.
