Maximus "Max" Giambetti, Jr. is a fictional character on the ABC daytime soap opera General Hospital. He has been played by actor Derk Chetwood since 2002. Max is the son of mobster Maximus Giambetti and the older half-brother of Milo Giambetti.
He has worked as a long time bodyguard and driver for mobsters Sonny Corinthos and Jason Morgan since 2002. In 2007, he became the head security guard for the Metro Court Hotel. After finding that too boring, he resumed his position as Sonny Corinthos' body guard. Max has been dating mob lawyer Diane Miller for 4 years. Max was shown to be particularly good with Sonny's children Michael Corinthos III and Morgan Corinthos when they were younger and he served as their main bodyguard. Also before dating Diane, he had a long time crush on Sonny's ex-wife Carly Corinthos, who he referred to as simply Mrs. C, but now he calls her The Former Mrs. C or Mrs. J. Max formerly worked as the primary bodyguard for Sonny's ex-wife Brenda Corinthos and her son Alec Scott before they left Port Charles and returned to Rome.
Max has been a faithful employee of Sonny's for years and often goes above and beyond what he is required to do. Max was there when Sonny was battling his mental illness and worked hard to protect his then wife, Carly and their sons. Also in 2006, when Jason took over Sonny's business because Sonny refused to stop dating his sister, Emily Bowen-Quartermaine, Max refused to take sides in their war, and instead opted to stay loyal to both men. During the Metro Court hostage crisis Max was shot in the shoulder. On August 25, 2011, Max and Diane ended their four year relationship and decided to go their separate ways. They parted amicably as friends.
In 2012, Max was present at Sonny's bachelor's party at Sonny's restaurant. He later is informed by his half-brother Milo that Kate, then Sonny's fiancee, made out with Milo and Olivia overseen. Milo later confesses to Sonny about the ordeal after Connie (Kate's alter) announces to the wedding guests that she as resurfaced.
