Doctor Fukurokov

Doctor Fukurokov (Dr.フクロコフ Dokutā Fukurokofu), an evil professor for the Battle Kukku Teikoku Academy, is the boss of Coco Island (not to be confused with the game's main island, Cocoa Island), in the game, Tails Adventure.

Description
He is the first boss of the flying fortress, encountered in the core of the invading bird's artificial island. He's an elderly owl with an odd, waddling manner of moving around and a very thick beard. He works as the Battle Kukku Army's main scientist.

As Fukurokov does not actually fight, he can't be attacked head-on. He instead lets his defensive machinery take care of Tails, for as soon as Tails approaches, the fox gets thrown into a trap chamber filled with spikes, lasers, conveyor belts, and a lone safe platform. Tails has to blast a way out of the chamber just large enough to sneak the Remote Robot through, in order for it to fly up crawlspaces and ventilation chutes. Then the robot can make its way back to Fukurokov and knock over a conveniently placed rock on a platform to bean the elderly owl right on the head.

After Fukurokov's defeat and Tails' escape in the Sea Fox, Coco Island rises up out of the sea and into the sky to reveal the Kukku Army's true stronghold, the Battle Fortress.

Archie Comics
Doctor Fukurokov had made appearance in Archie's Sonic Universe comics, as being higher member of Battle Bird Armada. He's the leading scientist, technician and also chief engineer of Battle Fortress. While working on the armada for many years, Wave the Swallow has known to being as his assistant for while until her escaping and joining to the Babylon Rogues. Unlike his game counterpart, Fukurokov wears a black hat similar to the battle lord's one and has grey open-toed sandals rather than blue ones. Due his name being hard to pronounce, he easily got furious to others who cannot spell right. Redesign of the character has done by Jon Gray.
