New details have been revealed about Spider-Man 2099's costume in Spider-Man: Across the Spider-Verse. Oscar Isaac first voiced the character of Miguel O'Hara, a.k.a. Spider-Man 2099, in the post-credits scene of Spider-Man: Into the Spider-Verse, but had a much larger role in the 2023 sequel as the leader of the interdimensional Spider Society. Adapted from the Marvel Comics character who debuted in 1992's Spider-Man 2099 #1, Miguel O'Hara is a very different Spider-Man to those with similar backstories to Peter Parker, as he was never bitten by a radioactive spider, and Across the Spider-Verse makes even more changes to this complex new Spider-Man.
