Stages of Transformation and Consequences

1. At this stage, only parts of his body have physically transformed into that of a beast. He loses his balance, as his newly changed leg can no longer support the weight of his torso the way a human one would. The man struggles desperately to stop the transformation, but the fur spreads faster than he can react, and the cracking of his muscles and bones grows louder and more unbearable. A strong, unpleasant odor seeps from his fur follicles, making the air around him thick and foul. Though his mind remains clear and aware, fear completely consumes him. He tries to yell for help, muttering to himself in a frantic attempt to stay calm.

2. 10 seconds before his upper body falls to the ground and becomes totally on all fours, despite of being devoured by brown, dark, thick fur, he tries to reason himself and try to stand on two legs. Flies and multiple unnamed bugs are attracted by the scent of wild animal mixed with sweat and dead skin cells—a raw, earthy smell that turns his stomach. He wants to twist his body and check how fast is his tail growing, but every time he tries, his spines become more attached and less curved, abandoning the S-shape back and turning into a rigid stick. The muscle of his arms and legs are more attached to his belly, so it's getting harder for him to move his limbs. He is also pressing his anus, feeling a great pressure inside. As he push, a thick, pungent secretion blobs out of his anal glands. He has no idea about biology, but the animal instinct soon makes him realize it's the secretion for marking his territory. He can't help but disgusted by the thought of rubbing his ass against the ground, letting the grass scratching over his anus, just to marking territory, like a nasty beast would do. Although the human tries to resist the rush to lie his arms, or front legs, on the ground, the inevitable fate for him to become an feral hyena still drag his front legs toward the ground, full of mud, grass and insects. Feeling strong anger and wronged, a flick of pleasure flew across his mind. He's now a dirty and a smelly beast. Nasty as he is, his muscle is becoming more dense and rough, his bones are becoming more thick and steady, too; he's getting powerful and unstoppable. Past troubles and disappointment toward human society and civilized rules doesn't bother him anymore. Still, knowing his fate, he tries to stand on two as long as possible, nevertheless it's just 10 seconds.
