Boxor were vehicles designed by Nuparu for defense against the Bohrok. Nuparu discovered an inactive Gahlok during the Bohrok siege of Onu-Koro, and thus discovered that the Bohrok were non-living machines meant to work with the Krana. With aid from Onepu and Taipu, Nuparu modified the Gahlok shell into a combat vehicle for use against the Bohrok. The Boxor works by using powerful punches to dislodge a Bohrok's Krana. Boxors were used successfully in the liberation of Onu-Koro and Le-Koro, but were defeated by Pahrak in Ga-Koro (as the Boxors sank in deep water). The Boxors were later used against the Bohrok-Kal, but were not very successful. Nuparu continued to make and modify Boxors until the Rahkshi appeared and the Matoran left the island. Some of the Boxors were brought to Metru Nui as a defense force.
