Guido (The Vampires of Venice)

Guido was the father of Isabella and a Venetian ship builder.

Biography
Aftergetting Isabella into Rosanna Calvierri's school, Guido discovered it was not what it seemed. He met the Eleventh Doctor following a failed attempt to get his daughter back, and the two became allies. Guido feigned another attempt as a distraction to let the Doctor gain entry to the school. Later he explained to the Doctor he had tried an underground passageway, but was blocked by a trap door. He offered to use the gunpowder he took from the shipyards while working on warships, but the Doctor refused.

When their plan failed again, the group met in Guido's house and plan their next act. The house was attacked by all the female Saturnynian converts, and while the Doctor, Amy and Rory escaped,Guido remained behind. He led the converts to his gunpowder, shouted "We are Venetians" and set light to it. The explosion killed everyone in the house, and ultimately doomed the Saturnynian race to extinction.

 * Due to the Cracks in time being negated, it is most likely that Saturnyne was never lost and the Saturnynians never came to Earth; therefore Guido never died.
