Kid Arachnid

Miles Morales is a teenage superhero from another dimension. He was bitten by another genetically-altered spider, giving him spider-like abilities. He took over the mantle of Spider-Man after the death of his world's Peter Parker. When currently living in the original universe where that world's Spider-Man is still alive, Miles took the name Kid Arachnid, without confusing his alter-ego with the original Spider-Man.
