As a domain expert in comic book lore and superhero narratives, I can provide an analysis of Superman's vulnerability to alcohol. Superman, also known as Kal-El, is a fictional character from DC Comics who is often portrayed as being immune to most earthly toxins and diseases, including alcohol. However, there have been instances in the comics where Superman has been depicted as experiencing the effects of alcohol, but these are generally considered to be exceptions rather than the rule.

In the Silver Age of Comic Books, it was established that Superman's Kryptonian physiology is vulnerable to the effects of "kryptonite," a piece of Superman's home planet, Krypton. In some stories, it has been suggested that a form of kryptonite known as "pink kryptonite" could alter Superman's biology in such a way that he could become intoxicated by alcohol. However, this is not a consistent or widely accepted aspect of Superman's character.

In modern interpretations, Superman's immunity to alcohol is typically portrayed as part of his alien physiology. His body processes substances differently than a human's would, which allows him to avoid the intoxicating effects of alcohol.

To summarize, while there are some exceptions and creative interpretations, Superman is generally considered to be immune to the effects of alcohol due to his Kryptonian physiology.
