G-Zero Racer
G-Zero Racers are high speed racing vehicles made especially for the G-Zero Grand Prix. They are a reference to the F-Zero racers.
In Ending 9 of Star Fox Command, Fox is so distraught from losing Krystal and from having Star Wolf take all of the credit for saving Lylat from the Anglars, that the only way that Falco is able to cheer Fox up is to re-engineer their Arwing fighters as G-Zero racers and racing until "their days as Star Fox became a distant memory".
