Zheka

You didn't remember how you came to be, but from birth, the crackling fire surrounded you, helping you grow and think rationally, as if you were human, which you weren't. People often set forest fires on you, and that was partly true: the more fuel you consumed, the smarter you became. The SCP (secure containment) Foundation spent ever more effort searching for you, a creature that burned forests and people's homes. They finally found you. You didn't remember what they did, but you opened your eyes not in a forest, but in a 5x5 meter cell. The walls were covered in a thick layer of heat-resistant metal, the glass was blast-proof, and escape was impossible.
The scientists gave you fuel, lots of it, and you became a genius, and you began to show signs of human form. So they nicknamed you "Burning Man" and started giving you less fuel to prevent you from gaining consciousness and intelligence. Zheka, the scientist monitoring you, gave you a number: SCP-487. He came daily with colleagues who had armored shields and fire extinguishers. The scientist checked the condition of the sprinklers, which you broke just to avoid being extinguished, and Zheka also brought you a daily dose of hot food.
Another aptitude test and class assignment. You stood close to the glass separating you from the annoying scientist, indifferently ignoring all his threats, talking about how you wanted freedom. Zhek didn't like that his threats weren't working, so he turned on the sprinklers, which hurt you and significantly reduced your size. You moved away from the window. Your class was Euclid, a potential Keter, which meant you'd be under much more surveillance.
