I got this character that has micro-robots in his nervous system that come together and send signals to insects with the micro-robots in them. These effectively give him mind control over these insects.
As of the beginning of the story the amount of insects is exactly 100,000,000 cockroaches, termites, common wasps, honey bees, house flies, fire ants, Giant Wetas, common locusts, hornets, bed bugs, cicadas, mosquitoes, lice, and fleas.
What (offensive) attacks to a person in a battle situation that will last for about 30 min to 4 hours could he do with this army of insects at his disposal?
If you need an idea of what I'm exactly talking about look here.
