Puccini is a resident of Soleanna in Sonic the Hedgehog (2006). He is a very famous and honorable professor who presumably lives in New City. He is said to be a leading figure in Soleanna's culture, and if he were to die, the heritage of the nation would be lost. He is usually seen driving a red car.
In Shadow's story, Puccini plays a major part in his eighth Town Mission, which is provided by a man called Nicolo. The man has noticed Puccini driving along the highway, apparently eager to reach his destination, but the road has become overrun with Iblis and Mephiles creatures and blocked by lasers, putting him in grave danger. Knowing about the importance of keeping the professor alive, Nicolo gives Shadow his mission: he must protect Puccini's car from destruction by defeating the monsters on the highway.
