G is for... Guido

A Venetian gondolier and boat builder who had saved for years to send his daughter to the city's exclusive Calvierri School for Girls. On enrolling her, he was shocked to discover that he would never be able to see his daughter ever again, and was also alarmed when he caught a glimpse of Rosanna Calvierri's son Francesco baring razor sharp fangs.
He then set about trying to catch sight of his daughter when the girls left the school on their frequent trips into the city. This drew him to the Doctor's attention. He had come to Venice to give his companions Amy and Rory a romantic holiday, after Amy had thrown herself at him on the eve of her wedding day. The Doctor decided to help Guido get his daughter back. Rory borrowed his clothes - lending him his stag-party T-shirt in return - whilst Amy would be enrolled at the school to give them access. The plan almost worked, but Guido's daughter - Isabella - had already started to be transformed into a vampire-like human-Saturnyne hybrid. She couldn't stand sunlight and was forced to retreat back into the school. Rosanna and Francesco were refugees from the nocturnal Saturnyne homeworld, who had come to Earth to start their race anew. The canals of Venice were full of male Saturnyne spawn, and the girls at the school were to become their mates.
Isabella was executed for helping the Doctor and her father. The schoolgirls then attacked Guido's house. He had stockpiled explosives taken from the city's arsenal, intent on using them to attack the school.
He sacrificed himself to blow up his house along with the vampire women.
