Scarlet Spider (Marvel Legends, Ares series)
The most stable of Peter Parker's many clones, Ben Reilly wandered for years, living the life imposed upon him by false memories implanted by his creator - the Jackal. When the memories of the true Spider-Man began to reassemble in his head, he returned to New York only to find Peter Parker living the life that Reilly thought was his. Though both clone and original at first competed against one another, their shared goals and high moral standards eventually led to them becoming close friends. Reilly considered Parker his brother to the last, when he sacrificed himself to save his genetic twin from the deadly Green Goblin.
