Clone of Spider-Girl, paired with a clone of the Symbiote
Technically a clone of Spider-Man created by Magus, though lacked any ability to actually impersonate the person Magus based it on. Only the Hawkeye and Daredevil doppelgangers shared the demonic looking flaw from the start.
Clone of Wolverine with a different chromosome, she is not just Wolvie's clone but in a sense his daughter as well.
Namorita is eventually revealed to be a clone of Namora.
Possible imperfect clone of Harry Osbourne
