Proto Sam-X was a prototype vehicle designed and built by Nya and housed in her Samurai X cave. For a long time, Nya had had the idea of creating a vehicle to match her Samurai X mech. Proto Sam-X was still unfinished (and not in the right colors) when discovered by Lloyd and Garmadon, who used it in their fight against the MechDragon. It was armed with a rotating harpoon missile, two laser cannons and concealed missile launchers.
