Alfano is a resident of Soleanna in Sonic the Hedgehog (2006). He is a high-level mathematician who lives in New City. Being a mathematician, he is a very intelligent man who claims to have an IQ exceeding that of Albert Einstein. He always prefers brain over brawn, believing that having a good intellect is highly important.
In the Shadow Episode, Alfano gives Shadow his second Town Mission. Knowing well about his strength and violent tendencies, Alfano believes that Shadow always uses his muscle and does not focus on his brain too often. With the intention of developing his intelligence, he gives him a series of brain training exercises, all of which involve answering questions based on number sequences.
