The term 'MASSIVE ASIAN WILD OX' refers to the gaurs, which are large wild oxen native to South and Southeast Asia. They are the largest species of wild cattle, with males reaching up to 2.2 meters tall and weighing up to 1, 000 kilograms. Gaurs are herbivores, living in grasslands, tropical rainforests, and deciduous forests. They are considered to be endangered due to habitat loss and poaching.
