Literary Critique of Duplication (imperfect)
Imperfect duplicates can be bizarre or evil but rarely both. Bizarro (DC) is by far the most famous example of a bizarre imperfect duplicate and first appeared in Superboy V1 #68.
Over the years Bizarro created a Bizarro World complete with a Bizzaro Code (Superboy V1 #68)!
In the Modern Age Bizarro was transformed from wacky to dark as exemplified in Alan Moore’s version of Bizzaro in Whatever Happened to the Man of Tomorrow? (Superman V1 #423).
Kara Zor-El II (DC) is an evil duplicate of Supergirl (DC) from the Modern Age. Interestingly, Kara Zor-El II has memories that make her think that she is not the duplicate but the original Supergirl.
Yet another evil Supergirl in Cosmic Adventures in the 8th Grade (DC).
Alan Moore made Supreme into a parody of Superman. The Shadow Supreme is Supreme’s version of Bizzaro.
