During the season one finale, Harry Osborn swore he would 'get to the bottom' of what happened between his dad and Spider-Man, and have his revenge, suggesting he would become a new villain later on.He only appeared once, still having the wolf's curse by the end of the episode. At no point did he ingest or get his powers from the serum. When the Scorpion finally appeared on the show, it was as as Badass Normal and later with a suit of Powered Armor. Aborted Arc: When the Lizard first appeared, a serum for scorpion mutations were seen as well.
