In front of his owners, Bunka acts as a mindless saber-toothed platypus, chewing up discarded stone blueprints. When duty calls, however, he sneaks off to receive orders from Monobrow and foil the evil schemes of the Neanderthal Doofengung. Surprisingly, Bunka makes no attempts to foil Doofengung, due to the Neanderthal's incompetence.
Bunka is a bunkaquan, otherwise known as a prehistoric saber-toothed platypus. The body shape is slightly stockier than a modern platypus. Bunka has pronounced brows, an unruly scruff of fur on top of his head, two sharp fangs protruding from the mouth, and a row of orange spines along his tail. In Secret Agent mode, he wears a horned animal skull.
Personality and traits
Despite their being nemeses, Bunka seems fairly apathetic towards Doofengung's schemes, making no attempt to stop him from provoking a mammoth stampede or even break out of his cage. This could be due to confidence that Doofengung will fail in his scheme, though it does not seem worth the risk. Bunka is also seemed to be a slight dumb in nature; when he crashed into Doofengung's place, Doofengung angrily pointed out that there's a cave opening next to him that Bunka could've gone through instead, much to Bunka's embarrassment. Also, after Doofengung's scheme is foiled, Bunka just leaves while carrying the bone cage that Doofengung trapped him in rather than just taking it off.
Skills and abilities
Bunka is able to quickly grind stone to gravel with his teeth, and digest this gravel with no adverse affects. He is also able to break through stone walls without faltering.
