Mirror Self

When you look into a mirror, you see a person who is in some ways identical to yourself, but who is also in some ways your opposite. If you are right-handed, your mirror will show a left-handed person, and vice versa.

This "same but opposite" is the cornerstone of a Mirror Universe. A character's "same but opposite" counterpart is the Mirror Self. However, a Mirror Self can sometimes also be created by misuse of Applied Phlebotinum.

Not to be confused with an Alternate Self, who is the same person without being an opposite. Might have gone through different experiences and been changed by them, but is not a polar opposite like the Mirror Self.

Anime and Manga

 * Subverted in Cardcaptor Sakura by the use of The Mirror card which creates an exact copy of Sakura that she can then control. Before her capture The Mirror appeared to be a michevious opposite version of Sakura but this is likely just the personality of the card itself and not because it's Sakura's reflection.

 * John Byrne retold Donna Troy's origin in Wonder Woman so that she was originally the mirror self of Princess Diana as a teenager, but given a separate personality by the sorceress who owned the mirror. Donna Troy was then captured by Queen Hippolyta's nemesis Dark Angel, who mistook her for Diana, and subjected her to live multiple lives that all ended in tragedy, ultimately leading to the one where Donna becomes Wonder Girl/Troia of the Teen Titans.
