Mobster Michael "Sonny" Corinthos Jr. is the most well-known member of the Corinthos family. He is the son of Adela Corinthos and Mike Corbin, born Michael Corinthos Sr. According to Mike, there was a time in his life when he was in some money trouble with people looking for him. He then decided to change his name from Corinthos to Corbin.
While growing up in Bensonhurst, Brooklyn, Mike left and divorced Adela when Sonny was a young age. Adela began an affair with Trevor Lansing, who was married at the time, and became pregnant with Sonny's brother, Ric Lansing. After Adela left Trevor she and Sonny were physically abused by her next husband Deke Woods who eventually murdered her.
Years later in 1993, Sonny came to Port Charles, being the owner of a strip club and Frank Smith’s right hand man. In 1994, Frank ordered Sonny to have Luke Spencer taken out. Sonny instead joined allegiances with Luke and they agreed to deal with Smith once and for all. When Sonny succeed in setting Frank up to be murdered he decided he would take over as head of Smith’s organization; a position he has held on and off for over a decade. In 1996, Sonny's father Mike, arrived in Port Charles as Luke’s driver. When Sonny discovered Mike was his father he wanted nothing to do with him and continually pushed Mike away. After much time, they managed to come to somewhat of an understanding.
Sonny developed a rocky relationship with Carly Benson nevertheless, the two fell in love and first married in the year 2000. This lead Sonny to adopt Carly's son Michael, whom was given Sonny’s namesake Michael Corinthos Jr..
In 2001, Mike’s old flame Janine Matthews came to town and was followed by her daughter Courtney Matthews. Janine revealed she and Mike had a fling in Vegas and Courtney was the result. Mike had walked out on them just as he did Sonny was he was young but Janine told Courtney that Mike had died. Courtney then immediately reconciled with Mike and Sonny became a loving, but overly controlling brother. A few months later, Sonny discovered he had another sibling when Ric moved to Port Charles.
During Sonny’s tumultuous relationship with Carly, he had a one night stand with Alexis Davis which produced a daughter, Kristina. Due to the fear of Sonny's lifestyle as a known mob boss, Alexis prevented the true paternity of her daughter from becoming public for over a year.
In 2003, Sonny and Carly celebrated the birth of their own son Morgan whom they named after their best friend Jason Morgan. That same year, Sam McCall had a one night stand with Sonny, and became pregnant naming the child, Lila. In 2004, Kristina developed leukemia and Alexis realized Lila’s stem cells could be used to save her. It was then that Alexis revealed Sonny was the father of her daughter. Unfortunately Sam went into early labor and Lila was still born. Lila’s stem cells were then used to save Kristina’s life and Sonny was overjoyed to learn that he still gained another daughter.
A few years later Courtney began an affair with Nikolas Cassadine and became pregnant. However when she contracted the encephalitis virus that was going around town in 2006, she dies right after giving birth to their son whom Nikolas later named Spencer. Mike was especially heartbroken at the loss of his daughter.
In 2009, Olivia Falconeri came to town and was followed by her son, Dante Falconeri. When Dante, a cop, infiltrated Sonny’s organization Olivia was forced to reveal Dante was their son from when they were teenagers in Bensonhurst. Dante was furious to learn that the infamous mob boss was his father, but both eventually formed a relationship. A few months later Mike left town, and went into rehab for his addiction to gambling. Dante and his mother then settled in Port Charles with Dante taking a job at the PCPD and eventually marrying Lulu Spencer. Together they now have a son whom they named Rocco.
