Bugernaut[1] (ブンブーン[2] Bun-bun?) is an enemy that appears in Sonic the Hedgehog 3. It is a mass-produced, horsefly-based Badnik model created by Dr. Robotnik.


Based on the horsefly, Bugernauts have a small blue body with a pair of large superposition eyes, four big wings and a cylinder-shaped abdomen on their back.



Bugernauts are found in Hydrocity Zone, and come in two sizes: a larger Bugernaut may be followed by a smaller one, but only the larger one can be destroyed. Buggernauts remain stationary above water surfaces, but will start buzzing around the playable characters when they approach them.

When the player defeats a larger Bugernaut by using a Spin Jump, the small Bugernaut becomes vulnerable and seeks out the nearest larger Bugernaut to follow it. If there are no large Bugernauts nearby, the smaller one flies away.
