After the destruction of
his hometown, Mach Rider jumped onto
his machine-gun-equipped combat motorcycle and set off in search of a new home, destroying all the Quadrunners who got in his way.
His motorcycle had four gears and endless ammunition. When hit, Mach Rider would break into fragments and then rejoin together. Mach Rider - 10/85
More these description here:
The Mach Rider appeared in the arcade
(It was essentially a modified version) to
Mach Rider,
Vs. Mach Rider (No canon). Each time the player completed a level, an image was gradually revealed of a woman with a dagger standing next to Mach Rider's bike. It is unclear whether this is meant to represent Mach Rider's true identity, or if she is a survivor in the gated community of the resistance, as the only plot text in the game describes the 10 mission scenarios and
she is not present in the NES original.
While
Mach Rider has not gained a true sequel, many elements from the game, such as the futuristic setting, incredibly high speeds, and aggressive racing have also been used in Nintendo's premier racing series
F-Zero, making it somewhat of a
spiritual sequel to Mach Rider. Even the title character of Mach Rider bears some similarity to the hero of the
F-Zero series,
Captain Falcon. (Because both characters are different)
