The Casebook of Jonathan Tesla follows the tragic character Jonathan Tesla, the first ZeoHuman, as he escapes from his captors and returns to Agarthia. There, he rises as a hero, seeking revenge and joins the Rebellion against The Fourth, an enemy of Agarthia from its darkest point in history, all while reforging the legacy of his legendary family.

What began as an idea for a short story set after the unnamed protagonist’s crash landing on an island, where he would encounter an individual teaching him survival skills while fending off a small army, evolved into the concept of “Living Legacy.” However, this narrative took a dramatic turn when J.I. Jones, yearning to return to his favorite creation, Jonathan Tesla, decided to strip back everything about the character, focusing on one aspect. During a discussion with a friend, another idea emerged: what if the villains were the architects of their own destruction? After just two chapters, J.I. realized the limitations imposed by the real world and began developing what would eventually become Great Agarthia.
