[b]"Herders"[/b] Originally a older control machines that dealt with vermine & insect. These where generally 0,3 millimeter sized machines (spore). The herder latch on its prefered prey and herd them to designated areas for easier termination or other purposes. Insects under some models could be used as controlled as cleaning crews or flower pollonators. These machines & their prey could become "carrier ships" and instigators of hostile & hungry vermine swams. When the living vermine died nanomachines swarms could erupt from the corpses and carry on the devestation. Inspiration: Region -a survival horror manga, Real life radiocontrolled cyborg insects [b]Fuel & Battery nano[/b] In essence a "intelligent" acid, nanomachines that act as fuel or battery acid, quite compliant & efficient when in their prefered enviroment. could be deadlier than hornets if their containment is broken or given a diffrent task. Inspiration:nanomachine compared to acid, battery acid, bee nests and a thread about breaching batteries.
