This papercraft is a Scout, a protoss space superiority fighter, based on the military science fiction real-time strategy video game StarCraft, the paper model was created by zxc6713. The Scout is a versatile and powerful protoss fighter though are generally considered by the protoss to be more for scouting purposes.
However, Scouts are easily a match for most other craft, employing anti-matter missiles against aerial targets and dual photon blasters against ground targets. The Dark Templar maintain(ed) their own Scouts and equipped them with technology to engage in FTL travel through the Void.
In their days of service, Scouts served as point guards for the protoss fleet, being maintained in the hangars of carriers, though were often called upon to engage hostile forces. Shortly before the war against the zerg, recent developments in enhanced sensor systems and high-power engines further increased its effectiveness.
Since the end of the Brood War, the Scout is steadily being phased out by the Phoenix. However, it is still used by the Tal'darim and Daelaam. [Source: wikia]
