Next tirthankar come
In Jainism, there are 24 Tirthankaras. Mahavira is the 24th and last Tirthankara of this cycle. The tradition does not name a specific successor or a fixed date for the next Tirthankar. According to Jain cosmology, after Mahavira, a new Tirthankar will arise in a future cycle, but the scriptures do not provide a definitive name or timeline for that event.
If you’d like, I can share how each Tirthankar is described in Jain scriptures and which qualities are highlighted for the next one when that time comes.
