Do any comic book writers portray superman as vulnerable to ordinary humans?
Quick Answer
The available evidence does not indicate that any comic book writer has portrayed Superman as vulnerable to ordinary humans.
Explanation
The only verified information we have about Superman comes from his creation by Jerry Siegel and Joe Shuster and his general description as a superhero with extraordinary abilities. This data does not mention any specific storyline, writer, or depiction in which Superman is shown to be vulnerable to ordinary humans. Without references to particular comic issues, writers, or narrative choices that depict such vulnerability, we cannot confirm that this portrayal exists. Therefore, based on the current evidence, there is no substantiated instance of a comic book writer presenting Superman as vulnerable to ordinary humans. If new sources emerge, this assessment may need updating.
