Answer

In Jain tradition, “bhav yuddh” is not the name of one single specific Arihant. It refers to the inner spiritual battle against karmas and passions. Every Arihant/Tirthankara becomes Arihant by destroying the four ghati karmas and attaining keval jnan. ( jaina.org)

Explanation

So, if you are asking which Bhagwan became Arihant after bhav yuddh, the correct Jain answer is: all Arihants do. If you meant a well-known example, Bhagwan Mahavir is the 24th and last Tirthankar in the present avasarpiṇī. ( jainknowledge.com)

Spiritual Understanding

The real “yuddh” in Jain Dharma is not an outer war, but the conquest of anger, pride, deceit, greed, and karmic bondage. That victory is what makes a soul Arihant. ( jaina.org)

Takeaway

No one single Arihant is uniquely called that because of “bhav yuddh.” In Jain Dharma, every Arihant is a soul who won the inner battle and became omniscient. ( jaina.org)
