Francesco is the secondary antagonist of the Doctor Who episode "The Vampires of Venice". He is Rosanna Calvierri's son as well as her second-in-command.


Francesco was the eldest of Rosanna's male children. He wore a perception filter and helped his mother capture girls to be transformed into mates for his brothers. After Amy Pond escaped from his mother's "school", he chased her. Rory Williams insulted his mother, distracting him, and tried to fight him. Returning to his true form, Francesco was killed when Amy reflected light from the sun onto him using a mirror, saving Rory in the process.
