Which character is revealed to be Dominic Toretto’s younger brother in F9?

F9 reveals that Jakob Toretto is Dominic Toretto’s younger brother.

Jakob is introduced as a skilled operative whose troubled history with Dom began during their childhood. The film explains that their conflict was connected to the death of their father, racer and mechanic Jack Toretto, whose final race had a lasting effect on both brothers.

John Cena played Jakob, adding another major action star to the franchise's ensemble. The character initially works against Dom's team but later becomes involved in the larger struggle against the antagonist Otto and the cyberterrorist Cipher.

Jakob's family connection was new to the audience in F9, so it is separate from the already established roles of Mia Toretto and Letty Ortiz. F9 was released in 2021 and was directed by Justin Lin.
