Cetos (Japanese: ブリキオ, Burikio) are Piscinoid enemies in Xenoblade Chronicles X. They are flying cetacean-like creatures with two disc-shaped organs protruding from their backs and light particles emanating from their fins, and are similar to Balaenas in appearance. They can be found in Noctilum, Oblivia, and Cauldros, and are nocturnal creatures.


"Huge fish that use atmospheric ether as a thrusting agent for aerial locomotion, storing the ether gas in their swollen abdominal cavities in order to stay afloat. Their backs are equipped with large echolocation organs designed to sense their surroundings and help subdue prey. Upon sighting a potential victim, cetos emit concetrated bursts of sound waves to stun the target before closing in for the kill."

"Cetos are sluggish, and their feeding habits slovenly. For this reason, one can often find wayward xiphias attached to their abdomens in hopes of securing a free meal."

Ceto may be derived from cētō, the singular dative or ablative of cētus the Latin word for whales that gave the Cetacae order name and the related taxonomic names (odontoceti, spermaceti, Mysticeti). It may be also derived from Ceto, the name of a primordial sea goddess in Greek mythology, or κῆτος (kētos), meaning a whale, sea monster, or large sea creature.
