There are four main types of marauder drones used by the Waruder hive consisting of the onyx and purple Parasite drones with their Ripper pilots, the yellow and burnt orange Mudfighter drones with their Thrasher pilots, the crimson and pewter Storm Rider drones with their Crusher pilots, and the white and purple Paralyzer drones with their Buzzer pilots. While each drone has their own specialties, their overall mission is the same - swarm, devour, and carry digested metals back to feed the rest of the aplary.
The larger drones are more or less simple techno-organic host shells that the smaller insects control as protective exo-armor. The shells are able to convert between insect and robot mode to suit the task required. The venom from the shell's stinger attacks both organic and technology based biological systems alike, numbing neural pathways and seizing motor control. The pilots themselves can convert into miniature versions of the shells' modes and, if desperate, they can also change into a third, ranged weapon mode that the larger shell can operate. However, this hand-held mode risks the pilots becoming detached from the larger insects, and rendering the shells largely useless as they have no intelligence or instinct of their own.
