You look at the unfortunate soul before you. You slowly walk over to the man spasming on the floor. He sees your approach, "Get back, monster! I'm not going to let myself become a freak like the rest of you." The pain and fear have not dulled his rage it seems. "Calm down," your new throat rasps out. You appear tp be having trouble talking after your own change into minotaur. "Screw you, cow!" he yells and reaches into his pocket. Standing up despite the pain if changing, he rushes you with a knife in hand.
New instincts take over, lending you new agility and anger. You dodge his thrust, grab him by the hair, and shove is face into the nearest pollen-spewing flower. "I'm a freak, am I?" you yell as you force his face deeper into the bloom. You don't know where this new rage is from but you suspect these strange plants have something to do with it.
Your opponent has stopped struggling and started shaking again. You feel his hair become coarser, turning into a bestial mane. Two bovine ears spread out from the side of his head. The man's clothes also burst apart as they fail to hold his expanding form. A tail drops out from his posterior as his pants fall away. Finally, his shoes burst as hooves arise from the shredded sneakers.
You pull his head out of the bloom and are unsurprised to see a bovine face appear. "Your a monster now," is all you say to the shocked minotaur.
