Miles Morales is a variant of Spider Man from the Ultimate Spider-Man comics series from 2011. His costume is similar to Peter Parker's in design, but varies drastically in color. This minifigure was released in 2015.
Miles is also the main protagonist of the 2018 movie, Spider-Man: Into the Spider-Verse.
Miles Morales was bitten by a spider that had been genetically enhanced with the Oz Formula. After discovering he had spider-like super powers, Miles was initially hesitant to use them, preferring instead to live a normal life. When Peter Parker was killed, Miles became inspired by Peter's philosophy, "With great power comes great responsibility" and decided to take on the mantle of Spider-Man.
