Foreign Intruder Defense Organism The Foreign Intruder Defense Organism or FIDO was a massive battle droid used by the New Republic in 11 ABY . Details . The FIDO was designed by the famed Mon Calamari Admiral Gial Ackbar and was brought to life by a team of top Mon Calamari scientists . It was designed to protect the entrance of a bunker , fortress or a safe house . Description . The FIDO resembled a large krabbex from a distance . It was composed of an eight - meter long pod connected to four - joint legs . Its pod was covered by a thick plasteel shell . It was equipped with a sensitive long range sensor and an advanced motion detector . The FIDO ' s primary weapons , its 26 claw - tipped cables , were kept in the pod and unspooled through a central grid . Its legs were designed to anchor the FIDO firmly in place once a strategic location was chosen and didn ' t provide mobility . If the FIDO ' s controller were camouflaged , the sensor and cable grid had to be left partly uncovered . The FIDO was sophisticated and intelligent enough to distinguish ally from enemy and was well programmed in battle tactics . Its controller supervised the action through protected sensors at the edge of each tentacle . The FIDO was also designed to fly if the situation got bad . Armament . The FIDO ' s primary weapons were 26 claw - tipped cables , each able to extend to a length of about 100 meters . These cables were influenced by the mouth tentacles of the krakana , a predator native to Dac , the ocean homeworld of the Mon Calamari . Each of these cables were capped with razor - sharp pincers cast from solid plasteel capable of cutting through transparisteel and even the armored hull of an Imperial Juggernaut . Since these cables were the only weapons of the FIDO , it had to use surprise when in combat , reducing " friendly fire " and collateral damage . If the FIDO was installed correctly , enemy forces would not detect it until it was too late to turn back . Then , they would be grabbed by countless durasteel cables and then destroyed by being thrown around or torn to shreds . Operation history . The first unit was deployed during the Battle of Anoth in 11 ABY against Imperial Mountain Terrain Armored Transport s under the command of Ambassador Furgan of Carida , who attempted to kidnap the youngest son of Han and Leia Organa Solo , Anakin . During the battle , the Foreign Intruder Defense Organism was pitted against eight MT - ATs . The FIDO unit destroyed four of the MT - ATs before succumbing to the fire of the rest of the spider walkers . Despite destroying the FIDO , Furgan was defeated by Leia and Terpfen , ending a major threat to the New Republic . Following that , the New Republic began producing more FIDOs though in limited quantity . To prevent others from stealing the design , its blueprints were categorized as Category Red classified information by the New Republic Intelligence . Behind the scenes . Author Kevin J . Anderson has said that the name FIDO was a reference to the FidoNet Star Wars Echo , an online message board he took part in at the time . The translation to Spanish of " Champions of the Force " kept the acronym by calling this droid O . D . I . E .
