Date of Birth: 1470.
A deadly import from Valencia, Spain, he grew up with Cesare, slightly his elder and always his protector. Not only Cesare's personal executioner, he also was a condottiero, leading armies for Cesare and, at one point, he was the governor of Piombino.
It might be easier to dispense with the chit-chat and simply list his known murders:
Giulio Cesare da Varano, lord of Camerino and three of his sons.
Alfonso of Aragon, Duke of Bisceglie and Lucrezia's second husband.
Oliverotto de Fermo and Vitellozzo Vitelli, strangled simoultaneously.
Astorre Manfredi, the Lord of Faenza.
Francesco Troche, the Papal Secretary.
And many more occurred that go unrecorded here. Micheletto was notorious for strangling his victims quietly and disposing of the bodies.
