Nicolo is a resident of Soleanna in Sonic the Hedgehog (2006). He is an ordinary civilian who can be found hanging around the streets of New City. He seems to show great concern for others, especially when they are in danger, and becomes frantic when he sees someone in this situation.
In Shadow's story, Nicolo gives Shadow his eighth Town Mission. He has noticed Puccini, a famous professor, driving down the highway of New City, but the road has been obstructed by Iblis and Mephiles creatures, as well as laser gates, and the professor is at risk of death. Nicolo claims that Puccini is "the top authority on Soleanna culture" and that Soleanna would not be the same without him. He gives Shadow the task of protecting Puccini from harm as he travels down the highway.
