Johnny Maranzano (played by Chris Tardio) is the son of the late, great Frank Maranzano, a mafia boss and owner of the Oceanic Casino in Las Vegas. He appears in "Big Daddy Calling".
Frank Maranzano was found at Las Vegas international airport with three heads in a duffle bag. The only two things he seems to care about are himself and money. He has no regard for his staff and constantly abuses them – verbally and sometimes physically as well.
He is not above killing anyone who crosses him and has people on his payroll everywhere in Las Vegas and LA. Johnny’s pride and joy is the biggest slot machine in the world called Big Daddy that is in his casino. It was created by him in memory of his father.
After the gang managed to rob Big Daddy, they proceeded to fake their deaths in a boating accident to escape Maranzano catching them.
