In F- Zero GX Mr. Zero can interview the the drivers for questions like, his motivation for racing, or what he/she thinks of the other characters. Sometimes he will ask for an autograph that will be sorted to a lucky viewer. When in the presence of one evil driver, like Black Shadow he shivers.
In the original F-Zero and F-Zero Maximum velocity, Mr. Zero is replaced by three electronic beeps.
Mr. Zero is a cyborg, with green hair and a green suit. Deppending of the difficulty level the player finishes the Grand Prix in F-Zero GX, Mr. Zero will be wearing a different suit. Green for novice, purple for standard, a lighter purple for expert, and white for master.
