At one point, the Battle Lord led his men in an invasion of Cocoa Island, but their aspirations were thwarted by the efforts of Miles "Tails" Prower. The young fox fought his way through the Armada's forces - including the Battle Lord's son Speedy - before engaging the leader of the Armada in fierce battle. Despite the Battle Lord's prowess, he was defeated in battle and his Battle Fortress fell into the sea. (VG: TA)
He reluctantly joined his fellow Egg Bosses in a group effort to help Eggman drive out the Naugus twins from Eggmanland. He was partnered with Abyss the Squid to shut down the backup generator, but both were ambushed by Dark Gaia Creatures. The Battle Lord managed to blow up the generator with his bombs, and soon aided Eggman during his confrontation with the Naugus Twins. (SU: #83, #84, #85, #86)
Soon after, the Battle Lord was contacted by Dr. Eggman, and was assigned to take down the Freedom Fighters' headquarters and main means of transportation- the Sky Patrol. From his fortress, the Battle Lord oversaw the Armada's attack on the Sky Patrol. (StH: #283, #284)
The Battle Lord is a tall avian dressed in a red coat (similar to Eggman's though far less flamboyant) and dark green pants with shoes and tail feathers of the same color, light orange/brown feathers and white gauntlets. He also has a large beak upon which rests a pair of small glasses also similar to Dr. Eggman's and a large, black hat with the Armada's insignia on the front.
- Battle Kukku XV first appeared in the game Tails Adventure. His design is identical to his original appearance with only minor alterations.
- Kukku XV seems to dislike the Babylon Rogues.
