Answer

In Jain tradition, Mallikumari is the 19th Tirthankar, Shri Mallinath Bhagwan.

Regarding a “brother of Sudarshana” connected with Mallikumari, I’m sorry, but I can only provide information that is clearly established within Jain tradition.

Explanation

The commonly accepted details about Mallinath Bhagwan are:

• Father: King Kumbha
• Mother: Queen Prabhavati
• Birthplace: Mithila
• Order: 19th Tirthankar

Different Jain traditions narrate certain details differently, especially regarding Mallinath Bhagwan’s gender, but the core reverence for Mallinath Bhagwan as a Tirthankar is accepted.

Takeaway

If you can share the exact story, book name, or context where “Sudarshana” and “Mallikumari” are mentioned, I can help identify the person more accurately within Jain tradition.
