The SPT-BB-02U Baybull was a general purpose super powered tracer developed by the Gradosian Empire. The Baybull was capable of functioning in multiple environments, including on the ground and in space. The Baybull’s armaments included a standard lasered gun and knuckle shots. In October 1996, Eiji Asuka stole three SPTs as part of his mission to warn Earth of an impending Gradosian invasion: Baybull, SPT-BD-03U Buldy and SPT-LZ-00X Layzner. When the Gradosian forces proved too much for Eiji to handle alone, Earth teenager David Rutherford stepped in to help by piloting the Baybull. The Baybull served as David’s personal SPT for the journey back to Earth, although it was briefly seized by the U.S. military upon his return. The Baybull was heavily damaged during the invasion and recovered by the Gradosians, who fully repaired it. In 1999, Le Cain used the repaired Baybull as a trap to draw out David, who was now a guerilla fighter. David successfully recovered his former SPT, but he was forced to abandon it when he discovered it had been booby trapped with a bomb. Although the Baybull was destroyed, David later upgraded to a new Earth-built SPT, the E-SPT-DL-X Doll.
