king Vira Narasimha, he helped the Chalukya-Chola ruler Rajaraja Chola III in restoring him back to his throne by repulsing the attacks of Aniyanka Bhima, Kopperunchinga II and the Pandyas. Subsequently, when the Vira Narasimha's successor Vira Someshwara, desirous of making the Chalukya-Chola ruler a puppet in his hands, joined hands with the Pandyas and attacked Rajendra III, Choda Tikka came to the rescue of the Chola emperor.

Manumasiddhi's forces led by Khadga Tikkana, the cousin of poet Tikkana won the battle, but the leader perished.
