>>552137Realistically? The human. Humans may not look like it compared to buff ass animals like bears but we're the apex predator just in our build. We have an immense amount of endurance compared to any other animal, we have a far larger upper strength capability and a peak physical condition person wouldn't have any trouble killing a elephant with their bare hands, let alone a kangaroo.
The reason so many people get their asses eaten by animals is because so many people aren't peak physical condition combat trained elites, a lot of people are fat and slow. Even most "physically fit" aren't anywhere near even a fraction of the potential they can reach through proper training.
It's not just "humanity is fucking the best" propaganda, humans are the best on Earth both in physical and mental potential. It is why we are where we are. The only animals we actually have a problem with toe to toe at both peak physical strength and experience would be other primates. An orangutan could probably snap a human in half over its head and a gorilla is a freight train. Both aren't too flexible and a human could put up a could fight against them, again if both were at top condition, but it'd be a closer run thing than Human vs Lion or Human vs Bear situations where just a decently built person could get by with mere superficial wounds.
