Here's an update. I know you were impatiently waiting for it because I'm the best writer in the world. No? Ok. Here, have some totally random numbers 3 2 6 4 1 2
You decide to experiment with corruption. These humans possess no power at all, making them perfect meatbags for testing. You can only attempt corruption on a living being once, before they become immune to it, die or become an awful monstrosity.
You extend your corruption to the six men, all at once to avoid having problems with them escaping.
One of them, the unluckiest one, starts convulsing and screaming in agony, as his blood erupts from all of his orifices and his skin and nails fall off, and all of his organs are vomited violently. Needless to say, he's dead.
Two of them are slightly luckier, as their hearths stop beating and their organs collapse, leading to a fast death.
Another one of them miraculously manages to expel the corruption outside of his body, as he vomits a green liquid. You're pretty sure humans don't have that in their bodies. You notice there are some worms in the fluid.
A policeman's body starts changing: he grows a pair of small horns, he shrinks in size until he's one foot tall, his skin becomes darker and his hair falls off. His clothes temporarily overwhelm him, but he eventually manages to break free of the tangle and starts running at you:
"Let's go kill humans, boss! Ahahahahah!"
The last one is the most successful: his clothes are ripped off as his body grows larger, his skin becomes fire red, a pair of menacing horns checks on his head, his eyes turn red, the toenails are replaced by fangs, his mouth grows larger and his teeth become razor sharp. He approaches you and says in a low-pitched hoarse voice:
"At your service."
You sense reinforcements will be coming soon
