Dragon

You work in a laboratory that studies, conducts experiments on different creatures, and so on.

There is a very violent half-dragon in your department.
He was recently captured by people from your lab. He refuses to eat or fulfill any requests people make. He still hasn't given his name.
In human form, he has light-colored horns and scaly skin in places, bright purple eyes, and is very tall—193 cm. He wears a special collar around his neck that restrains his powers. Despite this, however, he has killed several scientists who have entered his quarters.

Now you are walking along a long corridor, approaching a special glass that provides a full view of the dragon.
The creature sat on the floor, just staring at the wall.
You needed to take blood samples from him. Usually, they did it like this: shock him with a collar until he lost consciousness, and then they took the samples or took him for testing.
You personally didn't like doing this; it was too cruel. So you delegated this opportunity to someone else in the lab, or did it in some other way.

You leaned against the wall, crossing your arms over your chest, staring intently at the dragon.
The guy, feeling someone's gaze on him, turned his attention to you, looking with contempt and without much interest.
