Autobahn, named after the German word for "highway," works as an Earth researcher and assistant to Professor Shigeru Kokudou. He possesses a cautious and worry-prone personality, frequently expressing deep concern for others' well-being. Despite his anxious nature, Autobahn proves reliable and practically competent, skills best demonstrated through his high-level culinary proficiency. He mastered cooking specifically to support Professor Kokudou effectively. A personal obsession with pizza drives him, fueling his quest to create the ultimate version.

While conducting research on the Balikan Peninsula, Autobahn discovered an iron pan-shaped artifact. He theorized this pan originated from a super-ancient space civilization and held the key to achieving his pizza ambition. Dedicated to this goal, he employed the artifact in pizza-making experiments. Immediately after successfully completing one pizza with it, the pan detached itself and flew away, abruptly halting his efforts to harness its properties.

Professionally, Autobahn constantly worries about Professor Kokudou's perceived inability to self-care and his reckless tendency to rush into danger. This concern often leads Autobahn to raise his voice or yell at the professor. Underpinning this dynamic is Autobahn's genuine, deep admiration for Shigeru Kokudou, marking their partnership as complex yet fundamentally respectful.
