It's possible you're thinking of:
* Spider-Man: The main character, often called "Spidey" or "the Amazing Spider-Man."
* Boss: This term might be used casually for a powerful figure, but there's no official character called "Boss" associated with Spider-Man.
Can you tell me more about what you're looking for?
* What context were you thinking of? A specific comic issue, movie, or video game?
* What made you think of the name "Spider Boss?" Was it from a fan creation, a nickname, or a misunderstanding?
Once I have more information, I can give you a more helpful answer!
