The swaggering imperial overlord of the army. His powerful punch and explosive arsenal make him a vicious leader.

— Description, Sonic the Hedgehog Encyclo-speed-ia

The Great Battle Kukku[2] (グレイトバトルクック[3] Gureito Batoru Kukku?), also known by his full title Great Battle Kukku XV (グレイトバトルクック15世[4] Gureito Batoru Kukku Juugo Sei?), is the main antagonist in Tails Adventure. He is the leader of the Battle Kukku Empire who orchestrated an attack on Cocoa Island to seize the Chaos Emeralds for world domination, but was foiled by Miles "Tails" Prower.


The Great Battle Kukku is about twice the size of Tails. As a humanoid bird, he is mostly covered in light brown feathers, has long green tail feathers, and has a very large beak with an even larger lower mandible that resembles a large chin. Also, around his neck, he has a collar of white feathers. He possesses rather thin arms, but large forearms and hands, a pronounced and slightly round lower torso, and thin legs.

The Great Battle Kukku wears a large back hat in the shape of a bearskin with a rooster themed skull and crossbones insignia on the front and a long curl on the back. He also wears a pair of pince-nez glasses with dark blue lenses which covers his eyes. He is dressed in a red sleeveless coat, dark green one-pants with high-heeled shoes, white gauntlet with golden rims at the wrists, and white gloves.



At some point, the Great Battle Kukku had a son, Battle Kukku XVI.

Tails Adventure[]

Scheming to take over the world, the Great Battle Kukku lead his Battle Kukku Empire to Cocoa Island where the Chaos Emeralds were, so he could use their limitless powers for world domination. Arriving in the Battle Fortress, the Great Battle Kukku lead a massive battalion through Poloy Forest, destroying and setting everything ablaze while retrieving the Chaos Emeralds. Exhilarated by his impending victory, the Great Battle Kukku ordered his soldiers to find the last remaining Emeralds.[5]

From that point however, Great Battle Kukku's operations came to a halt when Tails began fighting the Battle Kukku Empire. When the Battle Fortress had re-launched from its concealed position, the Great Battle Kukku faced Tails in combat when he infiltrated the fortress. In the insuring fight, the Great Battle Kukku was seemingly destroyed and his fortress crashed while Tails escaped.


The Great Battle Kukku is a maniacal dictator-like figure and a master of evil.[3][4] When speaking, he has a tendency to end his sentences by crowing like a rooster.[5]




Powers and abilities[]

The Great Battle Kukku has demonstrated high physical durability, being able to withstand several exploding bombs up close before being defeated. He also has at least above-average-physical strength as he was able to lift up Tails with one hand and throw him a significant distance.


The Great Battle Kukku is the final boss of Tails Adventure. He is fought at the end of Battle Fortress 2 right after defeating Battle Kukku XVI.

Boss guide[]

At the beginning of the battle, the Great Battle Kukku will walk back and forth in the right side of the arena, flinging bombs in Tails' general direction. Though this attack can be avoided when walking on the ground by dodging the bombs, the player can avoid the attack by flying with Tails directly above the Great Battle Kukku, from where the player can at the same time drop bombs on the Great Battle Kukku. After having taken enough damage, the Great Battle Kukku will start moving across the entire arena, crouching down and rolling bombs along the floor when Tails is down low, which can be dodged by flying above the ground, and spraying them up high like a fountain when Tails is flying above, which can be dodged by flying directly above this boss. Also, if the player gets too close to the Great Battle Kukku, he will pick Tails and throw him across the room. After being hit fifteen times, the Great Battle Kukku will be defeated, and the player will have cleared this boss battle.

In other media[]

Archie Comics[]


The Grand Battle Kukku XV, from Sonic Universe #20.

In the Archie Comics' Sonic the Hedgehog comic books and spin-off comics, the Great Battle Kukku is referred to as Grand Battle Kukku XV. In this media, he was the fifteenth member of the Battle Kukkus and the leader of the Battle Bird Armada. Believing his people are destined for dominance, he searched for Babylon Garden in order to obtain control over Mobius. After a skirmish with the Knothole Freedom Fighters, the Battle Lord forced the Babylon Rogues to help recover Babylon Garden. However, his plans were ruined by Sonic who made Babylon Garden crash along with the Battle Bird Armada's base, and the Battle Lord swore vengeance.

After the timeline was rebooted by the Super Genesis Wave, the Great Battle Kukku became known as Battle Lord Kukku XV, or the Battle Lord for short, and became an Egg Boss of the Eggman Empire.
