Oscar Nero is a fictional character on the ABC daytime soap opera General Hospital. He is the son of former Navy SEAL, Chief Drew Cain and his former lover, Dr. Kim Nero.
The role was originated by Rio Mangini, who portrayed Oscar for two episodes on June 23 and 26, 2017.
Due to Mangini joining the cast of the Netflix comedy Everything Sucks, the role was recast with Andi Mack actor Garren Stitt, who debuted a week later on July 7.
He was conceived during a brief relationship his parents had in San Diego while his father was in the Navy.
Kim found out she was pregnant shortly after Drew was deployed and didn't think he would've welcomed a child with a woman he barely knew, so she decided not to tell him, although she did try to contact the Navy. However, her attempts to contact the Navy were initially unsuccessful, due to the fact that she was not a family member.
A couple of years later, when Kim did manage to get in contact with the Navy, she learned of Drew's "desertion." In reality, Drew had actually been kidnapped in an elaborate plot spearheaded by Cesar Faison and involving many of Port Charles' most notorious villains.
He is close with his father's family, the Quartermaine and has begun to get close with his uncle Jason.
Oscar was first seen at Josslyn's house for a party. Oscar and Josslyn shared their first kiss on September 14, 2017. After learning that his mother Kim knew Drew Cain in the early 2000s, they both began to suspect that Drew might be Oscar's father.
Joss swiped a coffee mug from Drew's penthouse (one he recently drank out of) after she and Oscar paid Drew and Sam a visit under false pretences. She then used the mug to run a DNA test. They got results but Oscar didn't want to know. Later on, Kim told Drew that Oscar is his son. Oscar and Drew have since hung out a couple of times and have decided to get to know each other.
Oscar eventually changed his mind and wanted to know. The test confirmed that Drew is indeed his father. After finding out, Drew went to see Oscar but it didn't go well. A few days later, Oscar went to see Drew at Aurora and they tried to get to know each other. On Christmas, Oscar decided to spend it with his new family the Quartermaine's. While there he meets his little sister, Scout.
On the 4th of July, Oscar spends the holiday in the park with Josslyn to watch the fireworks. They are joined briefly by Cameron Spencer and Oscar becomes slightly uncomfortable when he learns of Josslyn and Cameron's past closeness.
On September 5, 2018, it's revealed that Oscar has an inoperable brain tumor and may only have months to live. His mother has been searching for treatments for two years but there’s nothing anyone can do.
On September 24, Oscar found out about his cancer from Cameron and then it was confirmed by his parents. He felt betrayed by his parents as they didn't tell him and made him think he has years to live.
On October 17, Josslyn stated that it's Oscar's birthday.
