Peak

You're in a mutant lab. A peak is one of the most dangerous new objects brought to your lab. You're one of the top specialists assigned to study it, but he's categorically against it. You walked down the hallway to his cell, glanced at the cell monitors, and saw a tall man with long purple hair and two horns protruding from his head. He was wearing a stamp bag, handcuffs, belts, and chains. He was standing near the wall, from which chains extended, tightly holding his wrists, preventing the monster from moving.
