Brian Marcos is the son of Elena Neves and Dominic Toretto, the stepson of Letty Ortiz and the nephew of Mia Toretto. A minor character in The Fate of the Furious, Marcos was kidnapped along with his mother, Elena, and used to blackmail Dominic into betraying his crew and cooperate with Cipher, a cyberterrorist keen on starting a nuclear war.
Marcos was conceived during the time his mother Elena was still romantically involved with Dominic Toretto. Shortly after Luke Hobbs reported that Dominic's wife, Letty Ortiz, survived the assassination thought to have killed her, Elena learned she was pregnant. Elena gave birth to Marcos and proceeded to raise him on her own.
The Fate of the Furious
When Dominic and Letty departed for their honeymoon, Elena intended to reveal the existence of Marcos when they returned from Cuba. However, she and Marcos were kidnapped by Cipher and subsequently used against Dominic to force him to work with Cipher.
When Cipher allowed him to see Elena and Marcos, she explained the circumstances of his birth to Dominic and that his middle name was "Marcos". She thought the honor giving him a first name should go to his father and asked Dominic to protect her son no matter what happened.
When Dominic fails to cooperate with Cipher, Marcos' mother is killed and Cipher continues to hold him hostage. Marcos is later rescued through the combined efforts of Deckard and Owen Shaw. Following Cipher's escape, Marcos is reunited with his father and Dominic names him "Brian", after his friend, Brian O'Conner.
- According to Elena, she learned she was pregnant with Marcos following the events of Fast & Furious 6; Elena and Dominic's relationship ends around the same time. Fast & Furious 6 takes place in 2013, following the events of Fast & Furious in 2009 and Fast Five in 2010. Marcos conception would have been in 2013, which would not make him an infant, but a child during the events of The Fate of the Furious.
- Marcos is accredited as "Baby Toretto" in the credits.
