In Jain tradition, Prasenajit is known as a king who appears in older stories as one of the Kulakaras (early patriarchs) who taught or guided ancient society. There isn’t a specific, unique Jain scripture that makes him famous for a special connection to elephants. Elephants feature more broadly in Jain stories as symbols of power or in general royal contexts, but not as a defining trait of Prasenajit himself.
