Wikipedia:Articles for deletion/Comparisons between Superman and Batman
nearly the definition of original research.  I'm certain one could find individual comic books that have a situation where these two characters behaved toward each other in a certain way...but unless one could find an interview with the writer and artist of that comic book, any interpretation of the MEANING of that encounter only exists in the mind of the individual, not in any objective and verifiable state.  An article about a psychology textbook that uses Superman and Batman as examples might be excyclopaedic (something like The Simpsons and Philosophy: The D'oh! of Homer) but a straight up article that attempts to determine meaning, psychology and interpretation to these characters is exactly what  is intended to avoid
