The classic question.
Rules: This is a fight in an arena, you are unarmed, you cannot leave the arena until every other animal is dead, and while the animals are as intelligent as normal they do understand that they’re fighting you and will try to do so, they won’t just run away.
those animals are its ancestor and it retains many of the features that allowed them to be that size, it may not be optimized and couldnt live a full healthy life if simply scaled up but it wouldnt crumple like paper and would have long enough to crush you in its bill or crack your skull with its wing.
Idk been taking the duckpill since answering the first question and according to years-old farming forums their legs are already very weak and prone to injury, so the scaling might be enough to cause a collapse, especially if it has to speedwaddle after me
