What appears to be a second head on Qwilesect's back is actually a cannon capable of identifying its own targets. It uses pressurized water to expel sharp metal spikes, which may be coated with poison or charged with energy by various Drives.

This ancient bug Pokémon was altered by Team Plasma. A Qwilesect uses the pressure of water it swallows to shoot toxic quills all at once from all over its body.
