The NR-Shadow cycle, more commonly known as "The Spook cycle" is a specially crafted vehicle of Hero Factory.
It was originally created in order to test different types of power/fuel, but was eventually finished as a permanent vehicle. It is capable of running on gas, quaza, nitro-fuels, and multiple combustable substances. Users often crank up the boost, causing flames to erupt from the chassis, and pretty much every open compartment.
The vehicle can release toxic gasses, which cause inflicted targets to harm themselves in any way possible. It can also blast images of itself as any scary thing, creating the illusion to spook enemies out, hence its nickname. It can glide swiftly on almost any terrain, with it's slick blades instead of wheels.
The NR-Shadow cycle is fitted with two retractable spikes for ramming enemies. It is also equipped with a throwing arm, capable of launching disks great distances. It also includes two adjustable spikes, and ramming armor on it's front leg.
