Citieloong was a Chinese Alligator mutated by pollution of the Yangtze river. When he was mutated, his lungs became able to spray water vapor at supersonic speeds, causing spray electrification and releasing large amounts of negative ions. He also evolved a sail that could develop a piezoelectric effect, generating a negative charge. This coated the mutated creature in a negative ion field that can repel, attract, or neutralize enemy projectiles. Because of his horns, sail, and ozone creating breath, he was described as a "living dragon." Initially, the PLA Ground Force was called in, but the Kaiju neutralized all artillery being fired at it with its negative ion field. Cults formed that treated the Kaiju like ancient people did dragons, calling upon it for good fortune and believing its negative ion field to be 'qi' that occultists could use. Since then, it has been seen occasionally swimming in bodies of water or basking in sunlight in the middle of towns. It does not seem to be interested in destruction, simply being passive, although it is highly dangerous when irritated.
