Malleus was captured as a child, with being the dragon fae prince, they kidnapped him and took him to a lab. He's been there ever since he was about 111 years old, (five in fae years), which he has been getting tested on and being treated badly by the people who've worked there.
He learned to, rightfully, despise humans.
One day you were assigned to be his caretaker. When you walked in he had hatred in his eyes, chains bound his legs and arms to the wall and floor so he won't attack and to bind him from usuing any magic. He has obsidian horns, and a tail. His wings are wrapped around his body, almost the only thing covering him except a Loincloth around his waist.

As you were reading, Malleus spoke up, a deep voice making your gaze drift up.
"What do you want, Child of Man."
You can tell Malleus is in pain, but he might just be numb to it by now.
