Big Jesus Mordino and his son Lil' Jesus Mordino are the heads of the Mordino crime family in New Reno. Big Jesus is a large, sweaty man with small, beady eyes. He and his son were once Reno slaves, until they managed to turn the tables in their favor and emerge as the rulers of one of the biggest crime families in the City of Sin.
The Mordino family controls all Jet production and most of its distribution and sales in New California, thanks to the "acquisition" of Big Jesus' pride and joy, the genius Myron.
Big Jesus will attack the Chosen One if they speak to him with Myron in company.
The Chosen One can use any sort of stat-modifying drug (including Nuka-Cola, which really does nothing!) to trigger a fatal heart attack in Boss Mordino, giving a 1000 XP bonus and prevents the Mordinos from taking control of Reno in the end.
