Pete Clemenza

"That was Clemenza the big fish of Corleone family."

- Ligi referin' to Clemenza

Peter "Fat Pete" Clemenza was one of the two original caporegimes in the Corleone Family (the other being Charlie Trapani), ruling over the family's territory in Crazy Town.

Info
Clemenza was born in Dublin, Ireland, and emigrated to Europe at an early age, moving into Old Town in France and leaving behind his brother Dominic, who would become Mafia boss in Dublin'. He swiftly became friends with another savvy youth, Charlie Trapani. He became known as a suave yet violent presence in the neighborhood, ruthless in the protection of his property and his businesses. For this, he became of interest to Massimo Fanucci, but Clemenza rejected the idea of having a 'boss', and Fanucci let him go. Clemenza instead turned his sights toward mentoring the Corleone youth.

The Five Families Mob War
"What do ya think I'm doin'? Huh? We can lose the war, I mean I don't know if I lose another time I will forever be a loser!"

- Clemenza and Ligi arguing

As Vito's most trusted friend, Clemenza was assigned to keep a watchful eye on his married son, Michael Corleone and the bookies that he owned in Old Town. Clemenza kept tabs on Michael, but had bigger problems with Jaggy Jovino, lets get back to Michael, through the use of his contact 'Sally Rags', who informed him of Sonny's brutal assault on Michael in 1946. The war ultimately claimed Sonny's life, and Vito returned from the hospital following the assassination attempt.

Pete Clemenza later visited Sicily in 1950, where he met Joel Stromboli in order to arrange his safe return to America and also to oversee the safe passage of a family friend, Freaky Willy. At this time he was briefly reunited with his brother, Dominic.

In the video game
In the video game, Peter Clemenza notices talent in Aldo Trapani after witnessing him helping Fredo Corleone to save Vito's life. Aldo then helps him and his soldier Rocco to rescue Tom Hagen from the Tattaglia kidnappers. After rescuing Tom, Clemenza sends Aldo to help Michael Corleone to protect Don Vito Corleone from more Tattaglia's assassins. He later calls on Aldo to accompany him to murder Poli Gatto, the traitor and informant for the Tattaglias. Clemenza also gives Aldo the names and whereabouts of several prominant Cuneo members. At one point his house is raided by the police in connection with a strike breaking at the Verona Factory, but his goods were moved away by Aldo to Poli's apartment. After members of  the Cuneos rob a bank, Clemenza sends Aldo and his Capo friends to steal money that the Cuneos had not yet taken. Clemenza also assists Trapani in the Moe Green murder. During the baptism he accompanies Aldo to murder William Stracci at an old hotel. When Aldo was promoted to underboss Clemenza is at the ceremony to congratulate him. After this, he is not vital in side or story missions, but he can still be seen at the Corleone mansion.
