The move Brazen Bull of Phalaris is based off its name which is an old torturing killing method where they put you in a brass bull and heat it, cooking you alive.
Phalari's favorite method of torture was known as the brazen bull. This hollow bull statue was presented to him by a Greek artist named Perillos. The bull had a trapdoor installed in the belly, so the condemned could be shut inside the statue, and a roaring fire would be lit underneath. As the metal heated, the person trapped inside would be gradually roasted to death.
