Jeremiah looked up to his grandfather, and adopted his love of history. When Doctor Robotnik invaded Mobotropolis, Jeremiah not only evaded capture and roboticization, but, upon locating the city's abandoned library, secured it from being trashed or damaged and preserved his grandfather's book collection and other tomes detailing the history of Mobius throughout the time of Robotnik's reign.
After Robotnik's demise, Dulcy and Amy Rose, exploring a rough section of the still-rebuilding Mobotropolis in search of the library, found Jeremiah, and they, later with Uncle Chuck and Tails, learned a great deal of secrets on Mobius's history, most notably the events leading to the Great War. During Doctor Eggman's invasion of Mobotropolis, Tails, refusing to abandon Jeremiah, took several other Mobians and convinced Jeremiah to leave on the condition that the books be transported to safety as well. Jeremiah and the books are currently residing in New Mobotropolis Library.
