Who will be 25th jain tirthankar

There is no recognized 25th Jain Tirthankar in the traditional Jain scriptures. Jainism counts 24 Tirthankaras, with Mahavira being the 24th. The texts do not name a confirmed 25th Tirthankar. If you’d like, I can list the 24 Tirthankaras and summarize their key teachings.
