Ion Cannon

In science fiction, an ion cannon is a beam weapon that fires beams of ions (atoms or molecules with an electrical charge). Due to its power, it is usually classified as a superweapon. An ion cannon is a type of particle cannon; only the particles used are ionized. Due to their electrical charges, they have the potential to disable electronic devices, vehicles, and anything else that has an electrical or similar power source. Because of their classification as super-weapons, ion cannons have found their way into movies and television shows that have a science-fiction based setting. Ion cannons are also present in several games: Homeworld, Homeworld 2, the Command & Conquer series, Unreal Tournament 2004, Ogame, Ratchet and Clank: Up Your Arsenal, and StarCraft, for example.
