Battle Kukku Empire

The Battle Kukku Army are an army of birds that invade Cocoa Island (in the English language versions, the Army is renamed the "Battle Bird Armada" and Cocoa Island is "Tails Island") in Tails Adventure. They invade the island to snag the Chaos Emeralds which are hidden on the island. Tails battles the army and after he defeats their leader, the birds surrender. The Battle Kukku Army consists of uniformed birds, somewhat intelligent robot drones and advanced machinery. The Battle Kukku Army lives on a huge flying fortress that posed as an island throughout most of Tails Adventure.

Notable members

 * Grand Battle Kukku 15th, the dictator-like leader of the army. He is larger than most Kukkus, and is the final boss of the game battled in his flying fortress. He fights by throwing bombs all around him and throwing Tails himself if the fox gets too close.
 * Battle Kukku 16th, aka Speedy, the son of Grand Battle Kukku 15th. Speedy is a quick green Kukku who, despite his natural and fast aerial skills, sometimes wears armor equipped with an energy gun and a jet engine that lets him take even faster flight. He appears as a boss twice throughout the game, first on Pori Pori Mountain and then in the flying fortress just before the player faces his father.
 * Dr. Fukurokov, the army's main scientist. He is the first boss of the flying fortress, but does not actually fight, as he instead lets his defensive machinery take care of Tails. His tendency to overlook little details is his greatest weakness.
