Big Daddy is a supporting character in Sing and Sing 2.
He is the father of Johnny, and the former mobster leader of a gang of robbers in Sing. He wants for his son to follow in his criminal footsteps and his overbearing character makes it hard for Johnny to argue. He also owns a garage that he uses as a living space and a hideout.
Big Daddy is an anthropomorphic mountain gorilla. It is seen that he has a very large physique (hence the nickname "Big Daddy"). He wears a dark blue shirt and black pants. During robberies, he (and his helpers) wears a blue jumpsuit and a white rabbit mask.
Big Daddy seems to have a rough and strict attitude towards Johnny at first. He wants his son to follow in his footsteps and be an organized criminal, but scolds him when he wants to be a singer instead. After a botched robbery due to Johnny failing to have the getaway vehicle ready, he goes to prison and later shuns his son when he visits him. However, he became very proud of him after seeing his son's performance of "I'm Still Standing" on a prison television. Realizing what he has done, Big Daddy became desperate to see his son in person again and to apologize to Johnny for selfishly disowning him. He breaks out of jail and evades police pursuit long enough to briefly see and reconcile with him backstage during Mike's performance of "My Way" before leaving to turn himself back in.
Big Daddy and his crew turned over a new leaf that they were released from prison and allowed to complete their sentencing with community service, working for the CFS (Community Food Service). Big Daddy remains close and supportive of his son, for after Johnny called him to provide security, Big Daddy wasted no time coming to aid his son and his friends, protecting them from Jimmy Crystal and his security guards.
Big Daddy, along with the rest of his gang, are introduced conducting a bank robbery. While evading the police, he berates Johnny for failing to keep a lookout and not wearing his mask. Much later, Big Daddy ropes Johnny into being the getaway driver for a large heist of $25 million in gold. However, the time of heist conflicts with a rehearsal, and Johnny fails to return to his designated position, resulting in the gang's arrest.
In prison, Big Daddy finally learns about Johnny's desire to be a singer, and selfishly disowns him, even when Johnny swears to get him out of prison. However, when he hears Johnny's performance of "I'm Still Standing", and realize what he has done, he breaks out of jail to apologize to his son for his actions. When he reaches the theater, he reconciles with Johnny and tells Johnny how proud he is of him. He then promptly turns himself back in and goes back to prison.
Sometimes after Big Daddy and his crew were released from prison and finished community service, they begin to work for CFS. Upon learning from Johnny that Jimmy Crystal attempt to ruin their performances, Big Daddy and his gang are summoned to be their security guards. As Jimmy attempt to make his move to ruin the performances of Johnny's other friends and kill Buster Moon, Big Daddy and his gang defeats Jimmy's henchmen. Despite a minor setback when Jimmy threw Moon off the roof, until Rosita overcame her fear of heights and saved Moon from falling, Big Daddy caught Jimmy and forces him to watch the rest of the final shows, with the help from a redeemed Suki Lane. Following Jimmy's arrest, Big Daddy and his gang return to CFS while bidding his son and their friends a farewell.
