Chief Scientist Unit 01 is a unique Badnik operating on the Death Egg II in its damaged state, who appears in
Return to the Death Egg. Resembling a combination between a Metallix and Shortfuse the Cybernik, Unit 01 seems to be the most advanced Badnik on the Death Egg, at least in comparison to the older models on board. While capable of combat, 01's prime objective is scientific research. After downing Tails, he identifies him as a 'fox of unknown origins' and is set to perform examinations upon him, until Tails blasts the robot through the wall with a strike from his tails. Whether Unit 01 remained active after this attack is unknown, but it is assumed he was still in the vicinity of the Death Egg when it exploded.
