Description
Kiel Aronnax negotiated with Alcatraz's corrupt warden to uncover the prison's secrets, becoming a prisoner himself. During his incarceration, he encountered Sheyenne Rainstorm, preserved within the facility. Sheyenne's unique ability to wield ARMS technology and claim of connection to the Evil Race sparked Kiel's intense scientific interest. This meeting triggered Kiel's escape, aided by a distraction caused by thieves Loretta Oratorio and Mirabelle Graceland infiltrating the prison. Together, they located the prison's rumored treasure: Sheyenne himself. After escaping, Kiel joined Sheyenne's quest to recover his original adult body, forming a core group with Popepi Pipepo Isaac.

Kiel possesses a formidable physical build that defies typical scientific stereotypes. He exhibits considerable strength and proficiency in hand-to-hand combat, capable of subduing opponents directly. Despite his imposing stature, he maintains a thoughtful, reserved demeanor, often acting as the group's moral anchor. He prefers being called simply Kiel, rejecting the formal title "Doctor." His scientific background drives his analytical approach to challenges, especially concerning ARMS technology and Sheyenne's condition.

On the journey, Kiel assumes a protective, sometimes paternal role towards the child-bodied Sheyenne, leading outsiders to mistake them for father and son. This dynamic causes friction with Sheyenne, who retains his adult personality. Kiel guards undisclosed secrets related to Sheyenne's past and the circumstances of his body displacement. His path frequently crosses the treasure-hunting activities of Loretta, Mirabelle, and Jerusha (Isaac's ex-wife), resulting in recurring collaborations and conflicts due to differing objectives. Kiel's relationship with Jerusha involves typical interactions within the extended group, lacking deeper personal entanglement.

Kiel's last name references the narrator from Jules Verne's *20,000 Leagues Under the Sea*, though this bears no direct connection to his personal history or narrative function. His arc centers on supporting Sheyenne's mission through the dangers they face, applying both intellect and physical capability to overcome obstacles. He remains a consistent presence within the core quartet, prioritizing the search for Sheyenne's body and the truth behind the ARMS weapons.
