As previously mentioned, Spider-Boy's first appearance came during 1996's "Marvel Versus DC" crossover which introduced readers to the hybrid superheroes of Earth-9602, each of whom combine the powers of famous Marvel and DC heroes.
Within the lore of Earth-9602, Spider-Boy was created by Project Cadmus after they attempted to clone the Captain America/Superman hybrid "Super-Soldier" and augment him with powers of gravity manipulation. The project was sabotaged and the machine ended up cloning a young researcher named Peter Parker, with the original Peter dying in the wreckage. Adopted by Thunderbolt Ross, the clone "Peter Ross" was granted superhuman strength and speed, as well as gravity manipulation powers that allowed him to walk on walls in a manner not unlike a spider.
Taking on the name "Spider-Boy" in order to fight crime, Peter Ross was a major part of the "Marvel vs DC" crossover series, and recently made a cameo during the "End of the Spider-Verse" comic book event –- where his arm was ripped off by the multidimensional vampire Morlun in "Spider-Man #4" Vol 2. Unfortunately, despite being one of the more easily recognizable Spider-Man variants, it seems like these legal issues will keep Spider-Boy off the big screen for the time being.
