Miles Gonzalo Morales is a playable character inMarvel's Spider-Man and the main protagonist of the standalone spin-off Miles Morales. A 17-year-old teenager, he is a friend of Peter Parker and the son of police officer Jefferson Davis and councilor Rio Morales. He is also close friends with Ganke Lee, who knows about his secret identity and helps him on missions.

Peter befriends Miles after his father's death, introducing him to the non-profit F.E.A.S.T. shelter so he can serve as a volunteer and cope with his father's loss. Miles is unaware of Peter's secret identity as the masked vigilante Spider-Man, whom Miles idolizes. He eventually gains spider-like powers himself, which he reveals to Peter, who in turn reveals being Spider-Man. Under Peter's guidance, Miles attempts to step up as New York City's newest superhero, the second Spider-Man.

In the original game, a pre-spider bite Miles is featured as a playable character during some investigative stealth gameplay portions in the main story. In the self-titled spin-off, he is the main playable character, adopting both stealth and action gameplay mechanics similar to those of Peter's Spider-Man.
