Australian megafauna, such as the Diprotodon and the Megalania, coexisted with the first human inhabitants, the Aboriginal Australians. Evidence suggests that these early humans hunted some megafauna for food, which could have contributed to their eventual extinction around 46,000 years ago. Additionally, the presence of humans may have altered the habitats and ecosystems that these large animals relied on, further impacting their survival. However, the exact nature and extent of these interactions remain subjects of ongoing research and debate.

Mega fauna refers to large animals that existed in prehistoric times, often larger than their modern-day counterparts. These species played a key role in shaping ecosystems and many went extinct due to factors like climate change and human activity. Examples of mega fauna include mammoths, saber-toothed cats, and giant sloths.
One theory is that no one was to blame, it was a natural occurrence. The more commonly accepted theory is that fauna was over harvested by natives.

Many people credit the demise of large animals living during the last glaciation as due to the effect of the warming of the climate. Their extinction also coincides with with the first appearance of humans in many areas, particularly in North and South America. As humans always prefer to hunt the larger animals first, (more meat available for least energy expenditure), it seems more likely that they were hunted to extinction due to their inability to recognize humans as predators. Large animals in areas previously inhabited by Homo sapiens lasted much longer as they already knew them to be dangerous and would avoid them, if possible. This also applies to Australian mega-fauna, (giant wombats and kangaroos), which started to disappear at the same time as people first arrived on that continent.
"Mega Man OX" does not appear to be a well-known title or character in the Mega Man franchise. It's possible that you may be referring to a fan-made game or a lesser-known variant.
