Piranha Locust

Piranha Locusts are a species of flying predators which form huge swarms and devour flesh.

On the planet Bliss, Prof. Toshio Shimura combined genetic material from Piranha Locusts and silkworms fed on the metallic sap of the Ironweed trees to create a new species of deadly predators known as the Kiseibya.
