DNA Cannons are plasma cannons that can be programmed to only stun or eliminate creatures with a certain type of DNA. They are primarily mentioned in The Arctic Incident when Briar Cudgeon and Opal Koboi are plotting to use them against their goblin partners in the B'wa Kell rebellion. They can be coded to stun or eliminate anyone who isn't recognized by the computers, entire races, or certain members of a species.
