At the very beginning of the game he can be seen pursuing Black Shadow, Deathborn reaches him and forces him to wreck.
He grabs Black Shadow by the neck and tells him that he has one final chance of winning the F-Zero Grand Prix, and he warns him that if he dared to fail again he will pay the consequences.
When Black Shadow lost again the F-Zero Grand Prix, he appears from a dimensional portal and dispatched him for his incompetence, then he intruced himself to the winner as The Grand Prix Champion of the Underworld, he challenged Falcon into a race for the F-Zero and Underworld belts in the Underworld track.
Upon arriving Deathborn explains to the captain that their championship belts are condensed forms of Dark and Light and when they are united they forms a powerful object which gifts the possessor with an incredible power, with that he swears to turn the galaxy into a pile of ashes.
Upon being defeated by Captain Falcon, he loses control of his car the Dark Schneider and runs off the track into a river of lava, dying in an explosion.
